How should financial markets be regulated?
Dowd, Kevin ; Hutchinson, Martin
It is hard to imagine a more stupid or dangerous way of making
decisions than by putting those decisions in the hands of people who pay
no price for being wrong.
--Thomas Sowell
Financial regulation is a recurring and central issue in
contemporary policy discussions. Typically, leftists want more of it,
while proponents of free markets want less, or preferably, none of it.
We would suggest, however, that the central issue is not whether markets
should be regulated, but by whom--by the market itself, which includes
self-regulation by market practitioners, or by the state or one of its
agencies. To put it in Coasean terms, what is the most appropriate
institutional arrangement by which markets--including financial
markets--should be regulated?
This question is of fundamental importance to a sound retrospective
assessment of the Federal Reserve and is a prerequisite for sound
analysis of contemporaiy reform issues.
To answer this question, we should first consider what the term
"regulate" actually means. The primary and oldest meaning is
"to govern or direct according to rules." (1) However, the
term is often used in modern discussions to mean "control by
government agencies." This is a very different meaning, not least
because government bureaucrats often follow no rules themselves.
Instead, they have a vast amount of discretion to do as they please,
make up the rules as they go along, and issue lots of regulations in the
process.
Thus, regulation pertains to rules, but the term "rule"
is itself ambiguous. Sometimes the noun 'rule" means a bedrock
principle, but in other cases it refers to a stipulation from a
rulebook. In the former sense, a rule is long-lasting and there are not
too many of them; an example might be "Thou shalt not kill."
In the latter sense, a rule is reminiscent of the growing
micro-regulations drat abound in modem life. In this sense, a rule might
merely be bureaucratic discretion written down.
It is then clear that all conceivable systems have rules or
regulation in one form or another and the question at issue is not
whether to have rules or regulation but, rather, what form they should
take.
In this article, we explore this issue in the context of financial
regulation in the United States--and, more precisely, we compare the
very different systems of financial regulation that existed before and
since the founding of the Federal Reserve System a century ago. We
examine these systems from the perspective of how well they managed to
constrain (or alternatively, encourage) excessive risk taking on the
part of financial and other institutions, and we are particularly
interested in contemporary systems of government-sponsored financial
regulation such as Basel, Dodd-Frank, and the financial regulation
provided by the monetary policies of the Federal Reserve itself.
The storyline is one in which risk-taking discipline of the
original system was eroded over time by a series of government
interventions that not only kicked away the earlier constraints against
excess risk taking but strongly encouraged such risk taking, and so made
the financial system increasingly unstable. In the process, the
"tight" rules and self-managing character of the earlier
system gave way to more active management (or rather, mismanagement) and
growing discretionary (and largely unaccountable) power on the part of
the bureaucrats who ran the system with their ever-longer rulebooks. In
short, a basically good system became bad, and then worse.
We also emphasize the importance of the monetary backdrop. In the
old system, the discipline of the gold standard served to provide a
stable monetary environment that helped to rein in excessive risk
taking. Once the Fed was established, however, it began to manage the
system and first supersede and then replace the gold standard. It then
pursued activist monetary policies that produced boom-bust cycles, with
periods of low interest rates and loose credit feeding speculative
bubbles and inflation, and leading to one crisis after another.
How could this happen? The answer is the usual suspects--the
influence of bad ideas and interest groups subverting the coercive
powers of the state for their own ends.
Before the Federal Reserve: Regulation by the Market
In the years before the Fed, regulation was provided by the market
itself--that is, by the big players operating under competitive
conditions. When crises occurred, they would be dealt with by industry
leaders or by clearinghouse associations (see Timberlake 1984). These
provided emergency loans and in some cases issued emergency currency. A
distressed institution would seek assistance from the relevant club, and
club leaders would consider the request and respond in their own
interest. They would take account of the applicant's financial
health, its reputation, and the overall impact of their decision,
including the impact of possible localized contagion if they allowed an
institution to fail. An institution that was in otherwise good health,
and had been well run and had a good reputation, would be likely to get
a favorable response. A badly run and ill-regarded institution would
not. The good were helped and the bad were thrown to the wolves. Crises
were quickly resolved and any contagion, where it occurred at all, was
limited. The most famous example was the resolution of the 1907 crisis,
orchestrated by J. P. Morgan from his personal library, while the
government played no active role at all. (2)
There was little or no government involvement in resolving
financial crises, although government intervention and legal
restrictions were often important contributory causes of them. This
said, by modem standards there was limited government involvement. (3)
It is worth pausing to consider the main features of this type of
regulatory system, if we can even call it that:
* There was little formal regulation in modern sense.
* Such regulation as existed was created and operated by private
bankers' clubs.
* Rules were usually informal and left considerable room for
discretion on the part of decisionmakers. Indeed, their rulebooks are
best understood as codes of good practice or guidelines that evolved in
response to changing circumstances and lessons learned. Rules were
highly functional.
* Rules were created by industry practitioners who understood their
own business, operated under unlimited or extended personal liability,
and placed great emphasis on reputation, both personal and
institutional.
* The rule-malting process was self-interested and constrained both
by the profit motive and by market forces. Those involved understood
that bad regulations were costly and that they themselves would bear the
cost: this was why rules were few and the regulatory burden light. There
was also a process by which bad rules would be identified and weeded
out. One could say that the rule-generation process was modest and
subject to a robust error-correction mechanism--namely, the market
itself.
* The competitive process also applied to the regulatory systems
themselves: competition encouraged good innovations, which would be
widely copied. Individual member institutions also had the option of
opting out or joining other regulatory clubs; they could also set up new
clubs of their own.
* Participants operated against the backdrop of the monetary
discipline provided by the gold standard. By limiting money and credit,
the gold standard helped to counter speculative excess, allowing
overextended banks to fail and encouraging the survivors to conduct
their business in a more responsible and less system-threatening way.
The discipline of the gold standard also meant that interest rates and
the cost of credit were largely beyond the control of individual
institutions and more in line with market fundamentals than was later
the case.
Each of these features is very different from what we see in the
modern system. Underlying this system--indeed, making it possible--was a
conventional wisdom that was much more pro laissez-faire than that
prevailing today. Associated with this ideology were high levels of
personal liability and personal responsibility that created strong
incentives to keep costs down and rein in excess risk taking. These
incentives created a system that had strong governance features and was
highly effective--though by no means perfect--in controlling risk taking
and handling financial crises when they occurred.
We now discuss how these key features were each overturned.
The Establishment of the Federal Reserve System and an Expansionary
Fiat Monetary System
As a preliminary, we should emphasize that the period before the
Fed was not some monetary idyll; far from it. There were repeated
experiments with central banking in the earlier years and a considerable
amount of monetary instability throughout much of the 19th century.
Among the most notable examples were the crash of 1819, caused by the
monetary excesses of the Fed's predecessor, the Second Bank of the
United States; the disruption caused by the suspension of specie
payments and the move to a wartime economy with the onset of the Civil
War in 1861; and the crisis of 1873, which was due in no small part to
the U.S. Treasury's greenback scheme and by government promotion of
the Northern Pacific Railroad.
The United States formally adopted the gold standard only in
1879--a move intended essentially to revert to the status quo ante
bellum, but with the importance difference that the new system was a de
jure gold standard and not a bimetallism that functioned de facto as a
gold standard. However, the gold standard was still highly controversial
and bitterly opposed by the silver movement in the last decades of the
19th century--and became firmly established only with the victory of
William McKinley over William Jennings Bryan in the presidential
election of 1896 and the subsequent passage of the Gold Standard Act of
1900.
By then Britain had been on the gold standard continually and
successfully for almost 80 years with only one major crisis--that of
1825--compared to the succession of major crises that had plagued the
United States over the same period.
The Panic of 1907 led a few years later to the creation of the
Federal Reserve System by an act of Congress in December 1913. The Fed
opened its doors in 1914. Its principal purpose was to provide emergency
currency and a lender of last resort (LOLR) function, which conventional
wisdom wrongly presumed had been handled badly by the private sector.
The Fed was intended to operate subject to the discipline of the gold
standard. However, the Fed had barely begun its operations when the
First World War broke out. Belligerent countries suspended the gold
standard and the United States soon found itself the only major country
still operating on it.
Inevitably, the Fed had too much discretion and was too big a
player to be passively disciplined by the gold standard--and was soon
engaging in active monetary policy. This was very apparent in the later
1920s, when Benjamin Strong's policy of low interest rates helped
fuel the contemporary boom and subsequent bust. There followed the
catastrophe of the 1930s, to which the Federal Reserve's failure to
provide emergency liquidity to the banking system--remember this was
what the Fed had been set up to do--was a major contributing factor. The
response to this failure was to increase the Fed's power,
centralize the Fed's administration, and greatly expand financial
regulation. The most notable examples were the passage of the
Glass-Steagall Act, separating commercial and investment banking (and
decapitalizing the latter, which seriously hampered recovery), and tire
establishment of federal deposit insurance. The Fed then blundered again
when it doubled reserve requirements in 1936-37, which helped kill the
nascent economic recovery and push the economy into renewed recession.
In the meantime, the feeble international gold standard of the
interwar years--a much watered-down version of the classical gold
standard of pre-1914--had come and gone. Only tire United States had
remained on gold, but in 1933, President Franklin D. Roosevelt issued an
executive order effectively prohibiting private holdings of gold, and
the next year he revalued the official price of gold from $20.67 to $35
dollars an ounce--that is, he devalued the dollar against gold.
The new Bretton Woods system set up after the Second World War was
a gold standard only in the weakest possible sense. It was merely a
dollar standard with a commitment by the Fed to maintain the price of
gold, in a gold market from which private individuals and institutions
were almost entirely excluded. There followed the loose monetary
policies of the 1950s, and it was soon obvious that the United States
had a mounting inflation problem.
In A Program for Monetary Stability, published in 1960, Milton
Friedman provided a memorable assessment of the government's record
to date in stabilizing the U.S. economy:
The Great Depression did much to ... reinforce the now widely held
view that inherent instability of a private market economy has been
responsible for the major periods of economic distress experienced by
the United States. On this view, only a vigilant government, offsetting
continuously the vagaries of the private economy, has prevented or can
prevent such periods of instability. As I read the historical record, I
draw almost the opposite conclusion. In almost every instance, major
instability in the United States has been produced or, at the very
least, greatly intensified by monetary instability. Monetary instability
in its turn has generally arisen either from governmental intervention
or from controversy about what governmental monetary policy should be.
The failure of government to provide a stable monetary framework has
thus been a major if not the major factor accounting for our really
severe inflations and depressions [Friedman 1960: 9].
Post-1913, much of this instability was created by the Fed, and it
is fair to say that the Fed's record has not improved in the
half-century or so since Friedman wrote those words.
The monetary acceleration continued in the 1960s. This led to
rising inflation and the stock market surge of the late 1960s, which was
in many ways a repeat of the late 1920s. This bubble burst with the Penn
Central failure in 1970 and its attendant wave of brokerage
bankruptcies. By this point, the Federal Reserve was having great
difficulty maintaining its Bretton Woods gold peg, and in August 1971
President Nixon abandoned the peg and let the price of gold float. The
United States was now on a fiat currency without even the pretence of
any link to gold.
The way was now open for the highly inflationary policies of the
1970s and the necessary but painful monetary correction by Paul Volcker
from 1979 onward. Fast forward now to the late 1980s: inflation has been
brought down and Volcker has been replaced by Alan Greenspan as Fed
chairman.
Greenspan then introduced the "Greenspan put"--the policy
of propping up the stock market if it should plummet--in the aftermath
of the stock market crash of October 1987. This was followed by further
monetary easing in 1991. By the mid-1990s, however, Greenspan was
complaining of "irrational exuberance" in the stock market. He
responded by reducing interest rates, thus stimulating the boom of the
late 1990s; the centerpiece (U.S.) of which was the tech boom that burst
in 2001. He then responded by a more aggressive monetary policy that
produced an even bigger boom culminating in the crisis of 2008-09. His
successor, Ben Bernanke, then responded to that crisis with an even more
aggressive monetary policy--in the process stimulating the biggest
bubbles of all time and leaving policymakers with a huge headache.
Such policies led to an ever more damaging boom-bust cycle and to
the state of affairs described by Andy Haldane, the Bank's of
England's executive director for financial stability. Speaking to
the UK Parliament's Treasury Select Committee in June 2013, he said
that the "biggest risk to global financial stability right
now" is that posed by inflated government bond markets across the
world. He then told astonished British MPs: "Let's be
clear.... We have intentionally blown the biggest government bond bubble
in history." [4]
The same could be said for the policies pursued by the Federal
Reserve: the financial system wouldn't be so unstable if the Fed
hadn't tried so hard to stabilize it. The Fed's response to
the bubbles it has created is to blow even harder and hope for the best.
The Fed has got itself into a corner and has no credible strategy to get
itself out. We know that the latest bubbles must burst at some point and
when they do interest rates are likely to rise sharply as bond market
investors attempt to dump their holdings. When that happens the
financial system will collapse, again. The temptation will then be to
prop up bond prices by monetizing what could well be the entire
government debt, at which point the Federal Reserve's balance sheet
would explode from $4 trillion to $16 trillion or more almost overnight
and inflation will be off to the races.
Monetary policy has thus become progressively more destabilizing
and now poses an unprecedented threat to the U.S. economy. Federal
Reserve officials have no credible solutions to the problems they have
created. Instead, they merely offer lame excuses and ask us to trust
them one more time as they seek to gamble their way out and nothing is
done to hold them to account. Fed chairmen have appropriated enormous
power to themselves, and it could reasonably be said that the Fed
chairman now has more power over the U.S. economy than the president. In
these circumstances, it is hardly surprising that policy discussions are
increasingly dominated by "cult of personality" nonsense. No
matter how smart Alan Greenspan, Ben Bernanke, and Janet Yellen are,
none of them predicted the 2008-09 financial crisis.
The Federal Reserve as Lender of Last Resort
As we have seen, before the Fed, last-resort lending was managed by
the big players. If an institution sought assistance, the big players
would decide whether and on what terms to provide it. However, once a
central bank is established with its monopoly privileges, then the
last-resort function inevitably passes to it--in part because other
banks are restricted in their freedom to issue liquidity, but also
because this is now the explicit responsibility of the central bank. But
once the LOLR becomes a matter of central bank policy, what should that
policy be?
The classic answer was suggested by Walter Bagehot in Lombard
Street (1873). He suggested that the central bank should provide
last-resort support to solvent but illiquid institutions at a penalty
rate against prime collateral. The penalty rate would discourage such
requests (and make them genuinely last-resort), and the requirements
that the bank be solvent and offer first-class collateral should protect
the central bank against possible losses.
The existence of a central bank LOLR function gives rise to two
related problems, however. One problem is that of moral hazard: banks
might count on that support and behave less responsibly. The other
problem is that of how to credibly limit central bank support ex ante to
discourage such irresponsibility. These two problems are intimately
related. While a central bank might talk tough before the event about
how it would not bail out badly run banks, how it responds in the heat
of a crisis is another matter, where the pressure is on to arrange a
hurried rescue and never mind any threats it previously made to let
badly run banks fail. Ex ante, bankers know this, and might reasonably
dismiss such threats as lacking credibility and then do whatever they
want. This leads to a game of chicken that is almost impossible for the
central bank to win, and also to a big-risk moral hazard problem.
There is an interesting analogy here. Back in the f 8th century,
the British navy had a problem with weak commanders. A case in point was
Admiral John Byng. An inexperienced desk officer appointed commander of
the Royal Navy's Mediterranean fleet when the Seven Years' War
broke out in 1756, he failed to fully engage a slightly superior French
fleet at the Battle of Minorca. Instead, he retreated to Gibraltar after
an inconclusive battle, as a result of which Minorca fell to a French
invasion three weeks later. Public opinion in Britain was outraged and
Byng was court-martialed, found guilty of "failing to do his
utmost" to avert the loss of Minorca, and shot. It was this episode
to which Voltaire referred in a famous passage in Candide two years
later: "In this country [Britain] it is good, from time to time, to
kill an admiral pour encourager les autres." Byng's punishment
may have been a trifle harsh, but it worked--and no British fleet ever
again shied away from engaging a superior enemy force.
Reverting back to modern bankers, the Byng example suggests that
incompetent bankers should be shot. We would not quite go that far,
although another 18th century punishment, the stocks, is tempting.
However, our point is simply that they should be punished, not rewarded,
for their incompetence. The obvious way to do this is to impose some
personal penalty, such as the loss of a personal bond. (5) Incentives
matter.
There is no credible solution to this problem short of abolishing
the central bank. Indeed, it is interesting to note that Bagehot himself
acknowledged this point. As he wrote toward the end of Lombard Street:
I know it will be said that in this work I have pointed out a deep
malady, and only suggested a superficial remedy. I have tediously
insisted that the natural system of banking is that of many banks
keeping their own cash reserve, with the penalty of failure before them
if they neglect it. I have shown that our system is that of a single
bank keeping the whole reserve under no effectual penalty of failure.
And yet I propose to retain that system, and only attempt to mend and
palliate it.
I can only reply that I propose to retain this system because I am
quite sure that it is of no manner of use proposing to alter it. A
system of credit which has slowly grown up as years went on, which has
suited itself to the course of business, which has forced itself on the
habits of men, will not be altered because theorists disapprove of
it.... You might as well, or better, try to alter the English monarchy
and substitute a republic, as to filter the present constitution of the
English money market, founded on the Bank of England [Bagehot 1873:
331-32].
In short, Bagehot himself offered his rule as a second-best
solution to a problem that shouldn't have existed in the first
place, and could easily be remedied by abolishing the privileges of the
central bank.
The LOLR remit then expanded over time. The highlights of this
process include the bailouts of Continental Illinois in 1984, LTCM in
1998, and then those of much of the banking system in 2008-09, by which
point "too big to fail" (TBTF) was now firmly established as a
cornerstone of policy toward the banking system.
The history of the central bank LOLR thus embodies an interesting
policy logic. We wish to discourage banks getting themselves into
difficulties, so we rule out the first-best solution, free banking. This
is mistake number one. We then offer them help instead of punishment
when they get into difficulties: mistake number two. When they do get
into difficulties, we rarely apply the Bagehot Rule itself, but bail
them out instead: mistake number three. (6) Never mind all those earlier
promises that next time we really are going to let badly run banks fail.
Instead, the banks see those promises as exactly what they are--hot
air--and we duly find ourselves with the albatross of TBTF stuck around
our necks and a huge incentive for banks to take irresponsible risks.

Federal Deposit Insurance
Federal deposit insurance was established in 1934 under the
provisions of the Banking Act of 1933. Its proponents offered an
apparently self-evident justification that it would help tire banking
system by removing any incentive on the part of depositors to run. Yet,
federal deposit insurance was bitterly opposed by the bankers
themselves. It was, said the president of the American Bankers
Association, "unsound, unscientific and dangerous" (New York
Times 1933:14). Opponents argued that deposit insurance was bad because
it creates major moral hazard problems. In particular, it incentivizes
bankers to take more lending risks and to run down their banks'
capital, both of which would weaken their banks and make the banking
system less rather than more stable. They also pointed out that past
experience with compulsory deposit insurance systems at the state level
showed that it didn't work for exactly these reasons. (8)
A good example was Texas in the 1920s. To quote one contemporaneous
assessment of this experience:
The plan made too many banks and too few bankers. All kinds of
incapable people tried the start a bank under the protection of the
fund. The system gave a false sense of security--people looked to the
fund for protection and paid no attention to the soundness of the banks
themselves, nor to the ability of the managers. Prosecution of bank
wreckers and crooks was made impossible. The depositors got their money
from the fund, so they were not particularly interested in prosecuting
the unscrupulous or incompetent men who caused the banks to fail. Such
an unsound system of banking weakened the financial structure of the
entire state [quoted in Salsman 1990: 54],
As Salsman (1990: 54) aptly put it, "Federal deposit insurance
was instituted in 1934 under political pressure and expediency, despite
... prescient warnings and frequent references to the most basic
rudiments of economics."
It turned out that the critics were right. Banks' capital
ratios fell by more than half in just over a decade, and regulators were
never able to reverse the trend to capital deterioration created by
deposit insurance (Salsman 1990: 56-57). The adoption of deposit
insurance also led over rime to major changes in the banking industry
itself, which became less conservative and more prone to risk taking.
The eventual outcome was the great deposit insurance crisis of 1980s and
early 1990s and the destruction of much of the American thrift industry.
(9)
The "bad ideas" here are that banking is inherently
unstable and, relatedly, that that instability manifests itself in the
vulnerability of the banking system to runs--a vulnerability that can
remedied by deposit insurance removing the incentive of depositors to
run.
Ironically, just as the problems of deposit insurance were becoming
evident in the early 1980s, mainstream economists were persuading
themselves that we really did need deposit insurance after till--and
never mind the basic rudiments of moral hazard economics or even its
track record.
The seminal event was the publication in 1983 in the Journal of
Political Economy of the Diamond-Dybvig (DD) model, which offered a
justification for deposit insurance based on the fallacious premise that
the banking system was inherently unstable. This model rapidly gained
mainstream acceptance and is still accepted by the bulk of the economics
profession as providing the standard justification for it.
Their reasoning goes as follows. Imagine that we live in a
neoclassical economics world where we make up simplified models to
capture the essence of an economic problem. The model is our analytical
framework and is intended to guarantee rigor. In this model, individuals
live for two periods and are given endowments at the start of period 1.
They have access to a technology that will yield a return in period 2,
but don't know in which of the two periods they will want to
consume: these consumption preferences are only revealed after they have
invested. At that point, an investor is revealed as either type I, who
wants to consume in period I, or type 2, who wants to consume in period
2. Individuals can always invest in their own back yard and consume
whenever they want, but in that case, a type 1 investor would never earn
any return, because he would have to dig up his investment and consume
it before it had had time to produce any yield.
DD now suggest that everyone could be better off ex ante coming to
a mutual insurance arrangement in which they insure each other against
the risk of turning out to be a type I investor. DD call this
arrangement a "bank." The arrangement works if the proportion
of type 1 investors is known, but the DD bank is then exposed to a run
problem if the proportion of type I investors is not known. Everyone
knows that the bank does not have the resources to redeem all its
deposits at the promised rate if everyone decides to withdraw in period
I, because the underlying investment has not yet yielded a return but
the bank has committed itself to pay some return to depositors who
withdraw in the first period. This leads to the possibility that
individuals might get spooked and decide to redeem then deposits. To
prevent a system-wide bank run, the government would intervene and offer
a deposit guarantee. Everyone could than breathes a sigh of relief, and
the fear of a run goes away. Those who wish to consume early can do so
and, thanks to the guarantee, the others can be confident that their
deposits will be safe at the end of period 2.
Unfortunately, there are not one but three serpents lurking in this
Garden of Eden. The first is that the model involves a deus ex
machina--a methodological "no no" because it means that the
model is logically inconsistent. The problem here is that the deposit
insurance mechanism has to be feasible in the context of the assumed
model. So how would this mechanism work? Presumably, once the last type
2 depositor had withdrawn and the proportion of type 1 vs. type 2
depositors is revealed, then the government would be able to track
everyone down and arrange for the transfer payments between them to
honor the deposit guarantee. However, the model itself presupposes that
individuals cannot be traced once they leave the bank--it was exactly
the absence of any mechanism to track them down afterward that was used
to justify the existence of the bank in the first place. In short, DD
assume that such a mechanism does not exist when they motivate the
existence of their bank, but assume that such a mechanism does exist
when they propose their solution to the inherent instability to which
their bank is prone.
Well, either the mechanism exists in the model or it does not. If
it does, then the model's private sector can also use it and create
a run-proof and certainly different institutional structure to the one
postulated by DD. In this case, there is no need for deposit insurance.
If the mechanism does not exist, then neither the government nor anyone
else can make use of it either. In this case, deposit insurance would
not be implementable however much it was "needed"--it would
just not be possible. In a nutshell, in this model, properly considered,
deposit insurance is either not needed or impossible to implement. Take
your pick. Either way, the model can't be used to justify it. (10)
Even if we ignore the point that the model is inconsistent, there
is a second problem. Let's suppose for the sake of argument that DD
are correct that what is needed is a collective guarantee along the
lines of their deposit insurance scheme. Since this supposedly gives a
welfare-superior outcome, then everyone in their society will agree to
it voluntarily and there is no need for any compulsion by the
government. In other words, the market left alone would deliver their
preferred outcome--that is, we would have private rather than government
deposit insurance. So their model, taken at face value, gives no
justification for any compulsory system of deposit insurance.
The third problem is obvious to any banking professional though
apparently not to many academic financial economists: the bank in their
model has no capital. Such an institution is not a bank in any true
sense of the term, even within the ratified confines of a neoclassical
economic model. It is a mutual fund that tries to ape a bank by fixing
the values of its liabilities despite having uncertain asset returns and
no capital. Although DD call this institution a "bank," just
calling it a bank does not make it one. A true bank is a financial
institution that issues both debt (deposits) and equity. If DD had
called their financial institution a mutual fund instead of a bank, and
had then assumed that their mutual fund was going to issue fixed-value
liabilities, the problem with their financial intermediary would have
jumped out: you cannot have a financial intermediary with fixed
liabilities, assets that vary in value, and no capital and not expect it
to be prone to runs.
With this point in mind, consider an extension to the DD
environment. Suppose we have a type 3 agent who also has an endowment
but who differs from the other agents in knowing that she will not wish
to consume in period 1. This agent can then use her endowment to create
a financial institution that has the capital to offer credible
guarantees to the type 1 and type 2 agents. The institution can now be
described as a bank in a recognizable sense, and the type 3 agent can be
described as the banker. We then have an institutional structure that
resembles the banking systems we observe in the real world--in
particular, we have deposits, equity capital, depositors, and bankers.
And guess what? Assuming the banker has enough equity capital, then the
promised returns on early-withdrawal deposits can be credibly met even
if everyone runs on the bank. There is then no reason for any of the
type 2 agents to panic. In plain English, extend the DD model to allow
for bank capital and the DD problem of a run-prone financial
intermediary disappears. Again, there is no justification for deposit
insurance. Instead, depositors are reassured by bank capital--provided
that the banker has enough of it, but this is just a modelling
assumption. (11)
In short, there are only five things wrong with the Diamond-Dybvig
justification for bank deposit insurance:
* It is logically inconsistent.
* Even taken at face value, it provides no justification for a
compulsory scheme, since everyone would agree to it.
* It has nothing at all to say about banks--except those with zero
capital, and these should not be in business anyway.
* It ignores moral hazard issues.
* It is at odds with the historical evidence that deposit insurance
does not work.
Any one of these problems ought to preclude the model from serious
consideration, and yet this model is still the standard justification
for deposit insurance--another bad idea that has captivated the
somnolent economics profession.
Modern Financial Regulatory Systems (I): Features
Modern financial regulatory systems have quite different features
from the club-based systems of over a century ago: excessively long
rulebooks, high and growing costs, poorly designed rules, gameable
rules, and bad thinking.
Excessively Long Rulebooks
Perhaps their most striking features are their size and their
astonishing rate of rule production. In an article on Dodd-Frank
mischievously subtitled "Too Big Not to Fail," in early 2012,
The Economist noted:
The law that set up America's banking system in 1864 ran to
29 pages; the Federal Reserve Act of 1913 went to 32 pages;
the Banking Act that transformed American finance after the
Wall Street Crash, commonly known as the Glass-Steagall
act, spread out to 37 pages. Dodd-Frank is 848 pages long.
Voracious Chinese officials, who pay close attention to regulatory
developments elsewhere, have remarked that this
mammoth law, let alone its appended rules, seems to have
been fully read by no one outside Beijing (your correspondent
is a tired-eyed exception to this rule).
As if this wasn't bad enough, the article goes on to observe
that
size is only the beginning. The scope and structure of Dodd-Frank
are fundamentally different to those of its precursor laws, notes
Jonathan Macey of Yale Law School: "Laws classically provide people
with rules. Dodd-Frank is not directed at people. It is an outline
directed at bureaucrats and it instructs them to make still more
regulations and to create more bureaucracies." Like the Hydra of
Greek myth, Dodd-Frank can grow new heads as needed [Economist 2012].
Industry experts have suggested that the eventual Dodd-Frank
rulebook might run to some 30,000 pages, although we are tempted to
suggest that when it hits that target it will just continue to grow. As
Gordon Kerr (2013), notes: "The size of this mountain task is not
simply immense, it is unscalable."
Another example is Basel. This originated in the aftermath of the
serious disturbances to banking and currency markets that followed the
Herstatt bank failure in 1974. The resulting Basel Committee on Banking
Supervision was to provide a cooperative forum for the central banks of
member countries to discuss banking supervisory matters, and its initial
focus was merely to establish rules for bank closures. In the early
1980s, however, the committee became increasingly anxious about the
capital ratios of the major international banks deteriorating at the
same time as the international environment was becoming more risky. The
committee sought to reverse this deterioration and strengthen the
banking system--never mind the awkward fact that this deterioration was
in large part due to the incentives created by government deposit
insurance and the expanding LOLB function--while working toward greater
convergence across different countries' national capital
requirements. Thereafter, the committee experienced one of the most
remarkable cases of mission creep in history. Over time, the Basel
system transformed into a transnational regulatory empire that spawned a
vast cottage industry of parasitic "Basel specialists" whose
sole purposes were to interpret and implement the ever-expanding Basel
rulebooks. This Basel empire is growing at a phenomenal rate post the
utter disaster of
Basel II--and, thanks to its own repeated failures, is likely to
expand much further yet.
High and Growing Costs
There has also been a remarkable growth in the budgets, not to
mention the number, of regulatory agencies. Consider:
* The Securities and Exchange Commission budget request for
financial year 2014 is $1.67 billion, up 42 percent from 2012, and up 91
percent since 2007, versus 13 percent cumulative inflation according to
official CPI statistics.
* The Commodity Futures Trading Commission budget request for
financial year 2014 is $315 million, up 58 percent from 2012, and up 407
percent since 2007.
* The Office of the Controller of the Currency budget request for
financial year 2014 is $1,043 million, up 69 percent since 2007.
* The new Consumer Financial Protection Bureau budget request for
2014 is $497 million--and this agency didn't even exist in 2011.
There are also the costs of the Federal Reserve (with system
expenses up 31 percent since calendar 2007) and of Basel--and goodness
knows what they might be, although we can be confident that they will be
very high. (12)
We should keep in mind that these are only some of the direct costs
of regulations. We also need to consider the costs of compliance on the
part of regulated firms, who must employ their own armies of compliance
officers and establish cumbersome compliance procedures. Moreover, there
are the indirect costs of these regulations--namely, the costs of the
damage they do, including the costs of badly designed rules and the
costs of crises created or bungled by incompetent regulators.
Poorly Designed Rules
Modern systems are littered with poorly designed rules. Some of our
favorites are zero-risk weighting of sovereign bonds, pressuring soundly
run banks to take greater risks, regulatory endorsement of the Gaussian
(normal) distribution, and regulatory endorsement of the Value-at-Risk
(VaR) measure of risk and the mathematical modelling behind it.
Zero-Risk Weighting of Sovereign Bonds. In the original Basel
Accord, or Basel I, the debt of OECD governments was assigned a zero
risk weight. This implies that all such debt, including Greek government
debt, was assumed to be riskless. Its effect was to artificially
encourage banks to hold higher levels of government debt than they
otherwise would, and was a major contributor to recent EU banking
problems. When the Eurozone sovereign debt crisis escalated a couple of
years ago, many banks then suffered major and otherwise avoidable losses
on their holdings of government debt. This rule has been repeatedly
criticized, but is still on the books.
Pressuring Soundly Run Banks to Take Greater Risks. In private
correspondence, John Allison gives an entertaining story of how
regulations impacted his bank, BB&T (see also Allison 2013). This is
a conservatively run institution that that did not suffer a single
quarterly loss since the onset of the crisis. The bank did not have
highly sophisticated risk management systems. It did not need them
because it did not take excessive risks. The risk models it then
submitted to the Fed under the risk supervisory process used its own
loss experience, which was much lower than the industry average.
However, supervisors rejected their models and demanded that the bank
use more sophisticated models and industry loan-loss experience instead
of its own. This requirement saddled the bank with an unnecessary model
development cost of over $250 million and a higher regulatory capital
charge--and will force the bank to take more risk to pay for the extra
costs involved. In short, in the interests of promoting good risk
management and discouraging excessive risk taking, the Federal Reserve
forced a well-run bank to adopt highly expensive risk management
technology that it neither wanted nor needed, imposed higher regulatory
capital requirements that were not justified by the risks the bank
wanted to take, and will then force the bank to take extra risks that it
didn't want to take in order to recoup its higher costs.
Regulatory Endorsement of the Gaussian Distribution. The most
widely used statistical distribution is the Gaussian, or normal, and
this is the standard distribution used in risk management too. However,
the Gaussian is suitable only for statistical problems relating to the
central tendency of the distribution, such as problems involving means.
It works in such situations by virtue of the Central Limit Theorem.
However, in risk management we are interested in the tails of the
distribution and this theorem does not apply to the tails, which are
governed by the very different Extreme Value Theorem. In fact, the
Gaussian assumption gives extremely poor estimates of tail
probabilities.
To give an example, in August 2007 there was talk of hedge funds
getting hit by "25 sigma" events--losses that were 25 standard
deviations away from expected losses. It was repeatedly said in the
media that these were so extreme that one might have to wait 10,000 or
100,000 years to expect to see such losses on a single day. However,
such claims were manifestly wrong because the losses suffered by the
hedge funds were not in fact that rare.
But now ask the following question: How long would we have to wait
to see one such daily loss if the world were Gaussian? The answer is
1.309e+135 years--that is, 1.309 years, but with the decimal point moved
135 places to the right (see Dowd et al. 2008: 3). This number is about
equal to the number of particles in the universe multiplied by the
number of nanoseconds since Big Bang multiplied by all the atoms in all
the bodies of everyone who has ever lived times multiplied by a few
trillion, give or take a few zeros. The probability of observing such
losses is about on a par with seeing Hell freeze over. The take-home
message is that since such losses are not that uncommon, the Gaussian is
totally unsuitable for estimating tail risks.
Regulatory Endorsement of the VaR Risk Measure and the Mathematical
Modelling behind It. The VaR (Value-at-Risk) measure of risk is a
percentile on a probability density function that gives the cutoff to
the relevant tail, and is used to determine banks' regulatory
capital requirements. Unfortunately, it is of very limited use for
banks' financial risk management because it does not tell us
anything meaningful about the tail itself--that is, the VaR is blind to
tail risks. The VaR is rather like a chocolate tea pot: it looks good
with all that fancy math until it is actually stressed with a little hot
water. There is also evidence that the bigger, more complex and more
expensive, VaR models perform worse than much simpler ones (Berkowitz
and O'Brien 2002). Any benefits from all that extra complexity
appear to be more than outweighed by the many implementation compromises
that "sophisticated" models inevitably entail.
It is important to stress that most of these problems have been
known for a long time, and yet these rules remain on the books.
Gameable Rules
Even worse than poorly designed rules are poorly designed rules
that are gameable. These are highly destructive because they encourage
the looting of bank capital and the furtive offloading of risks onto
other parties, often with serious systemic implications. The following
are several examples, all of which have regulatory approval.
Capital Plundering or How to Destroy Securitizations. A major
feature of Basel is the way in which positions hedged with credit
derivatives get a risk-weighted capital charge of 0.5 percent, whereas
the standard default charge for most positions is 8 percent. This opens
up opportunities for clever financial engineers to come up with scams in
which portfolios that would otherwise attract healthy capital charges
can be reclassified as hedged for Basel purposes and the capital
released for "better" uses--such as paying bonuses to the
clever financial engineers who designed them and their managers (see
Kerr 2010; also Kerr 2011, 2013). The banks that employ them are then
left seriously capital-depleted even though their risk-adjusted capital
numbers are, if anything, improved.
Hidden Hypothecations. This is another set of scams--examples
include "failed sale" and some covered bond
securitizations--in which banks furtively pledge assets to
counterparties while the assets ostensibly remain on their balance
sheets. The banks then enter into arrangements with other counterparties
who do not realise that those assets are not recoverable in subsequent
bankruptcy proceedings. Such hypothecations deceive the later
counterparties, who don't realize how weak their counterparties
really are, and are in essence fraudulent (see Dowd, Hutchinson, and
Kerr 2012 for more details).
Hidden Re-Hypothecations. Many transactions involve the posting of
collateral by investors who assume that their collateral is safely
tucked away in a vault with the institutions they entrusted it to. The
reality is that collateral is often secretly re-hypothecated--quietly
posted elsewhere--and it is not uncommon for the same collateral to be
re-hypothecated a dozen times or so.
This problem became apparent with the MF Global meltdown in late
2011.
To quote one informed commentator:
MF Global's bankruptcy revelations concerning missing client
money suggest that funds ... were instead appropriated as part of a mass
Wall Street manipulation of brokerage rules that allowed for the
wholesale acquisition and sale of client funds through re-hypothecation.
A loophole appears to have allowed MF Global, and many others, to use
its own clients' funds to finance an enormous $6.2 billion Eurozone
repo bet. If anyone thought that you couldn't have your cake and
eat it too in the world of finance, MF Global shows how you can have
your cake, eat it, eat someone else's cake and then let your
clients pick up the bill [Elias 2011],
The magnitude of this problem is enormous:
Engaging in hyper-hypothecation have been Goldman Sachs ($28.17
billion re-hypothecated in 2011), Canadian Imperial Bank of Commerce
(re-pledged $72 billion in client assets), ... Oppenheimer Holdings
($15.3 million), Credit Suisse (CHF 332 billion), Knight Capital Group
($1.17 billion), Interactive Brokers ($14.5 billion), Wells Fargo ($19.6
billion), JP Morgan ($546.2 billion) and Morgan Stanley ($410 billion)
[Elias 2011],
In other words, re-hypothecation is yet another disaster waiting to
happen.
SPV Financial Alchemy. There is, finally, the old classic of SPV
financial alchemy. (13) You start with a portfolio of credit-risky
bonds. In fact, even better if it is a portfolio of very credit-risky
bonds: in this game, the junkier the bonds, the better the alchemy
works. Let's say that this portfolio would attract a particular
credit rating, C, say, which is the lowest S&P rating north of
default. You now set up a special purpose vehicle (SPV), which buys the
portfolio and issues tranched claims against it. The trick is in the
tranching: the junior tranche protects the senior tranche by absorbing
the first losses, and only after the junior tranche is wiped out do
claimants to the senior tranche lose anything. A not atypical
arrangement is a 20/80 split between junior and senior tranches, after
which the senior tranche attracts an A, even AAA, rating, and can be
flogged off to investors accordingly. And so a pile of junk--financial
lead--is converted into 80 percent gold and only 20 percent lead, even
though the risks in the underlying pool remain exactly as they were. You
then repeat the process again on the junior tranche and others like it,
and repeat as many times as you like, each time converting more and more
of the toxic waste into investment-grade investments in a manner
reminiscent of the way in which the mafia make the proceeds of crime
respectable by repeatedly laundering it. Unfortunately, when a crisis
occurs, the financial magic is apt to suddenly wear off and much of the
"gold" then reverts to its original leaden state--and
investors discover the hard way what they had really invested in.
Again, we emphasize that each of these practices--and many others
like them, and they are very widespread--greatly increase systemic
instability in the banking system.
More Bad Thinking
Underlying badly designed rules is some seriously bad thinking.
A Regulatory Risk Management Standard. A major objective of modern
financial regulation, especially Basel, is the promotion of a regulatory
risk management standard. At first sight this objective might seem
reasonable--it connotes the benefits of, say, standards for accounting
or physical measurement--but the reality is that it flies in the face of
how markets actually work and embodies a major fallacy of composition.
Consider the following: If we were dealing with a single
institution, we might advise it to move out of risky positions when a
crisis occurs. This makes sense for a single player but the market as a
whole cannot divest itself of risky positions--someone has to hold them.
There is, consequently, a fallacy of composition in which the individual
institution can sell, but the market as a whole cannot. The collective
attempt to dump such positions then sends prices down sharply and
creates a vicious spiral, in which the collective attempt to move out of
risky positions makes those positions even riskier. The fundamental
problem is, then, that the encouragement (by regulators or anyone else)
of a single risk-management strategy itself destabilizes the market.
Market stability requires players who pursue different strategies: when
many firms are selling in a panic, we need other institutions willing to
move in and buy. (14)
Financial Regulation Should Mimic the Market. A common assertion
among central bankers and financial regulators is that financial
regulation should somehow mimic market incentives. One distinguished
exponent of this view is Alan Greenspan, who really should know better.
Speaking at the Chicago Fed Conference on Bank Structure and Competition
in May 1997, he said:
I believe that in many cases, policymakers can reduce potential
distortions by structuring policies to be more
"incentive-compatible"--that is, by working with, rather than
around, the profit-maximizing goals of investors and firm managers.... I
readily acknowledge this is often easier said than done. Nevertheless, I
believe some useful guiding principles can be formulated.
The first guiding principle is that, where possible, we should
attempt to strengthen market discipline, without compromising financial
stability ... A second guiding principle is that, to the extent
possible, our regulatory policies should attempt to simulate what would
be the private market's response in the absence of the safety net
[Greenspan 1997].
But this argument leaves the goal wide open: if you want market
incentives, simply have market incentives and be done with it.
The fallacy here is that regulators can have their cake and eat it
too. They don't want genuine free markets because they would entail
unpleasant outcomes like bank failures--and the regulators themselves
would be out of a job. So they imagine that they can avoid such
unpleasantness by establishing a bank safety net to ensure that banks
don't fail. This seriously distorts the incentives that banks face,
and they then imagine that by some regulatory sleight-of-hand they can
recreate the incentives created by fear of failure in a regime where
they themselves have removed that fear.
Scientism. A veritable minefield of problems relate to the
regulators' (and industry's) addiction to scientistic
thinking--the naive application of physical science models and ways of
thinking to social science problems where they do not belong. This
mindset is wrong for a whole host of reasons, but let's just cite
the following four:
* It assumes that social processes such as markets can be described
by stable laws of motion. However, stable laws exist in physics but not
in markets: market processes are changing all the time. Any
relationships that do get picked up by empirical methods are fleeting
and apt to break down, especially when market participants attempt to
use them. For example, market participants are apt to model stock price
processes and use their models to develop trading strategies, but those
very strategies change the stock price process itself.
* It fails to take account of the reality that many risks--in fact,
most of those that really matter--are not quantifiable at all. These are
the "unknown unknowns" famously defined by Donald Rumsfeld.
Modelling such risks is impossible by definition.
* It ignores that effective risk management is often undermined by
senior management. The problem with good risk modelling is that it leads
to high estimates of financial risk and hence high capital charges. This
ties up capital and curtails risk-taking, both of which reduce
bonuses--and this will never do. In most banks, an overly diligent risk
manager risks confrontation with his or her superiors and will likely
soon be out of a job.
* Last but not least, scientism in finance--which usually goes by
the name quantitative finance--is insanely wedded to the VaR risk
measure and the Gaussianity assumption.
It is almost superfluous to point out that scientistic drinking is
a key reason why risk modelling--by the regulators or the
industry--almost never works.
Constructivist Mindset. Underlying scientism is the constructivist
mindset with its tendency to believe in "planned" solutions.
Suffice here to note that the problems with this mindset were
beautifully set out in a well-known passage from Adam Smith ([1759]
1976: 380-81):
The man of system is apt to be very wise in his own conceit; and is
often so enamoured with the supposed beauty of his own ideal plan
of government, that he cannot suffer the smallest deviation from
any part of it. He goes on to establish it completely and in all
its parts, without any regard either to the great interests, or to
the strong prejudices which may oppose it.
He seems to imagine that he can arrange the different members of a
great society with as much ease as the hand arranges the different
pieces upon a chess-board. He does not consider that the pieces
upon the chess-board have no other principle of motion besides that
which the hand impresses upon them; but that, in the great
chess-board of human society, every single piece has a principle of
motion of its own, altogether different from that which the
legislature might choose to impress upon it.
One of the many curiosities with this mindset is that it imagines
that there is some perfect solution out there that is superior to
whatever the market can provide--this is just taken from granted as an
article of faith--and that all that is needed is to delegate some body
of experts to identify and implement it. The resulting solution comes
back obviously full of holes (e.g., Basel II), and those in charge are
then surprised when it does not work. Their response is to repeat the
exercise again but typically on a more grandiose scale. The new solution
is a bigger failure and they repeat the mistake again, and again. There
is no reflectivity or learning by experience built into the process.
Instead, there is an unchallenged assumption that there is no other way
to think about the problem and the naive belief that "we will get
it right this time" without ever pausing to consider why it
didn't work all those times before. We then have another instance
of Einstein's notion of insanity--repeating the same mistake but
each time expecting an outcome different from all die previous ones.
Modern Financial Regulatory Systems (II): Rule-Generation Process
It is also interesting to consider the process by which the rules
are generated. The first point to recognize here is that those who
generate the rules do not bear the costs of the rules they produce. On
the contrary, it is in their interest to produce long rulebooks to
justify their own existence and argue for more resources to produce even
longer rulebooks. Modern financial regulatory systems have a built-in
incentive to produce massive and growing oversupply, and the correction
mechanisms that used to constrain rule-generation no longer exist. Those
involved are no longer governed by the profit motive, and regulated
firms can no longer opt out or set their own competing regulatory clubs.
If we ever hope to tame these systems, we have to find some way to
ensure that those who create these rules bear at least some of the costs
of the rules they generate.
A second point is that the earlier learning mechanisms that
governed rule-generation no longer exist. Since there is no competition
amongst rule-generators, it is no longer possible to rely on competition
among alternative regimes to eliminate bad rules and promote good ones.
We are then in the classic command economy situation where we no longer
know how many bakeries or what the price of bread should be, since we
have suppressed the only mechanism that could tell us. We are then
dependent on the wisdom of bureaucrats to make these decisions for us.
The main exception is competition at the international level--
competition between the various national regulatory bodies--so how do we
deal with that? The answer is that we seek to suppress that competition
too in the name of "harmonization." Instead of leaving die
United States, the European Union, Japan, and others free to offer
competing regulatory systems, with the jurisdiction with the better
practices gaining some advantage, and in so doing pressuring the others
to follow suit and improving the quality of regulation overall, we
suppress that process and hand over the harmonization process to a
committee instead. Once again, we replace a good rule-generation process
with an inferior one. (15)
A third point is that the rule process becomes a politicized
committee process that is accountable in the main only to itself. The
process is then subject to all the pitfalls of committee decisionmaking:
a tendency to duck difficult issues, engage in horse-trading, and
promote excessive standardization; a vulnerability to politicization and
domination by powerful individuals with their own agendas; and a
vulnerability to groupthink and a proneness to go for solutions that
look good on paper but don't work in practice. It also leads to
overemphasis on a culture of compliance with no thought given to the
costs involved. When it comes to risk issues, it often leads to a total
obsession with risk modelling and capital management--which they
don't understand anyway--with those involved becoming so bogged
down with the risk metrics that they lose all sight of the risks. It is
also often the case that the rules are so obviously poorly put together
that those involved are too embarrassed to defend them afterwards, even
though they signed off on them. (16)
There is, thus, a serious accountability gap that can't be
resolved unless there is some mechanism to make the individuals involved
personally responsible.
To make matters worse, modern regulatory systems are also prone to
capture:
* Financial firms have vastly greater resources, so they can hire
the best talent and assemble expert teams in relevant areas (e.g.,
financial modeling, accounting, and law) giving them the ability to
outgun the regulators, especially on complex technical issues, and set
the agenda. By comparison, regulatory bodies are often short-staffed and
have inadequate research support. Consequently, regulatory officials are
often outnumbered and outgunned in meetings. They are also hampered by a
steady exodus of their staff, who take their skills and institutional
knowledge to the private sector, where they are far better paid.
* Firms are often able to hold carrots in front of individual
regulators with the prospect of lucrative future jobs. As a result,
regulators are often reluctant to challenge firms for fear of
jeopardizing their own prospects.
* Financial Firms wield big sticks; they have great influence and
powerful friends, who can (and sometimes do) bring pressure to bear and,
where necessary, intimidate individual regulators who get in their way.
Their greater resources also allow firms access to superior legal
firepower, which means, in practice, that they can often get their way
merely by threatening the regulators with legal action.
* There is the cozy relationship between the financial industry
giants, the regulatory system, and the government. Key players move back
and forth between all three, leading to industry capture, not just of
the financial regulatory system, but of the political system too.
The regulatory system is also captured by the regulators
themselves, who use it to promote their own interests--to promote an
agenda that emphasises their importance, promotes their power, and gives
them more resources.
Nor should we forget that the regulatory process is also captured
by politicians who use it for their own ends: to promote reforms that
they have rarely thought out, to grandstand, and to help friends in the
industry who pay their campaign contributions.
The Volcker Rule provides a perfect example. This is an offshoot of
Dodd-Frank that had the worthy intention to ban proprietary trading by
financial institutions on government support, and hence stop at least
one avenue by which traders could speculate for personal gain at the
expense of the taxpayer. Threatened with the loss of one of its favorite
lunch buckets, the industry responded by lobbying extensively for
exemptions. In so doing, they "took a simple idea and bloated it
into a 530-page monstrosity of hopeless complexity and
vagueness"--effectively killing it off by filling it full of holes
(Eisinger 2013). The regulators themselves supported this process for
their own ends: they stood to gain from more regulations and the
resources that go with them, and from an extension of regulatory
discretion. (17) Neither the industry nor the regulators had any stake
in making the Volcker Rule effective, so the end result-- the appearance
of the Volcker Rule, but without the substance--is hardly surprising.
Note how this arrangement satisfies all three principal
participants: the politicians get their legislation and are seen to be
doing something (and never mind what), while the industry and the
regulators get their way in ensuring that the Volcker Rule is unworkable
--and the fact that this arrangement is horrendously costly and doomed
to failure doesn't matter to any of them.
Regulatory capture is also the main reason why so many bad
regulatory practices persist, despite their weaknesses being well known.
They persist because their weaknesses serve the purposes of key interest
groups. An example is the Basel rule giving credit derivatives a 0.5
percent capital weight, which enables financiers to construct all manner
of dubious securitizations, such as the "how to destroy" scam
mentioned earlier. Other examples are the regulatory endorsement of the
Gaussian assumption and the VaR risk measure. These lead to major
underestimates of true risk exposures but are convenient for the
industry because they lead to low capital charges. Capital that should
be used to buffer banks against risk can then be siphoned off as
dividend and bonus payments, and senior management can play dumb when
the bank later collapses and the taxpayer is required to pay for the
bailout. (18)
Putting these points together, we have an undisciplined
rule-generation process that is out of control. Everyone including the
regulators complains that the rules are burdensome, excessive, and often
make no sense--and yet the system produces ever more of them. They also
lose any contact with their underlying supposed rationale--to control
risks, protect investors and so forth--and often become
counterproductive. In the end, the process of rule-generation becomes
the end in itself. We then get to the point where there are so many
rules, so many consultation papers, so many meetings, so many agendas
and so many changes in agendas, that even the regulators who produce all
this gumpf can no longer keep up with the juggernaut that they have set
in motion. Nevertheless, the regulatory apparatus continues to grow, and
it doesn't matter that the regulatory burden continues to expand or
that none of this regulation actually works.
Basel II is a case in point. This was in essence just thousands
pages of regulatory gibberish with the ostensible objective of ensuring
that the international banking system would be safe. It was rolled out
in June 2004 and had just been adopted--in the EU and Japan, though not
yet in the United States--when the crisis hit and the banking system
collapsed. In their resulting panic, bank regulators across the world
then rushed out many thousands of pages of new draft rules, plus many
more pages of discussion and consultation documents. Indeed, so great
was the deluge of regulatory material that by spring 2010 observers were
jokingly referring to it being tantamount to a Basel III. By the fall of
that year, however, Basel III had become a reality and the joke was on
the jesters. But the real jesters are those telling us that the solution
to all that gobbledegook was now to have even more of it, crafted on the
fly under crisis conditions by the same people who had gotten it wrong
the previous time, not to mention the times before that. And remember
that Basel II had been produced over the course a fairly quiet decade,
whereas Basel III was the product of a few months' panic.
If one thing is for sure, it is that this ever-inflating system
will certainly fail again. When it does, we can expect it to further
ratchet up its expansion--and presumably again and again, assuming the
whole system does not collapse before then--until the parasite has
weakened its host so much that the host can no longer function.
This example reminds us that modern financial regulatory systems
are not only prone to failure but actually thrive on it. In any sensible
system, failure would lead to some error correction or negative
feedback. However, in modern financial regulation--not to mention that
of the 1930s--the opposite is the case. When it fails the response is
not "Let's get rid of all that useless regulation because it
has failed," but rather "Let's create a regulatory system
that works." In practice, this always gets hijacked into
"Let's have even more of it." Instead of being held to
account, they use the crisis they help create to push for even more
power and resources and fob us off with excuses and promises that the
new system really will work next time. When it comes to monetary policy
and financial regulation, it is truly the case that nothing succeeds
like failure. It is no wonder, then, that regulation has such a tendency
to ratchet up.
There is also the problem of there being no mechanism to make rules
or policies consistent. Indeed, consistency becomes impossible. Faced
with rules that clash, those who apply the rules--the regulators--are
then increasingly free to pick and choose which rules to cite or which
to apply. Defenders of the regulatory system can do the same: whatever
the problem, they can point to some rule that addresses it--and never
mind that this solution is contradicted by some other provision
somewhere else. They can argue, with the appearance of plausibility,
that their regulatory systems address any and all problems, and they
would usually be right, on paper--provided one ignores all those
inconvenient contradictions or the track record of repeated failure. We
are tempted to describe this as a perfect example of Coasean textbook
economics. But it is in fact far worse than Coase ever imagined.
If regulators can pick and choose which rules to cite, or to
apply-- and who outside the regulatory system can keep up with rules to
challenge them?--then the whole process becomes one of regulatory
discretion and there are no longer any rules in the proper sense of the
term. We then have the appearance of rules but the reality of
unaccountable discretion on the part of those managing the system: they
can do whatever they want. Ironically, the rulebook becomes a license
for almost unlimited discretion; it is then literally "discretion
written down"--and there is no mechanism to hold regulators or
policymakers to account.
It gets worse. The system has rules, but they are superseded by
discretion, which is to say, the system doesn't really have any
rules at all. At the same time, there is a huge regulatory burden, so
rules do exist in that sense--and they are ineffective too. It is hard
to imagine a system less fit for purpose.
And this takes us to the most sinister and most damaging result of
unaccountable officials doing whatever they want: the subversion of the
rule of law. If we have so many rules that no one else can keep up with
them, and if the regulators are free to pick and choose the rules or
polities they apply, exploiting inconsistencies as they see fit, and if
there is no effective mechanism to hold them to account, then we are no
longer living under the rule of law; we are living under a regulatory
dictatorship.
The good old system didn't have any of these problems because
it had features that the modern systems so conspicuously lack: incentive
structures and accountability mechanisms that worked, and underlying
those, the rule of law.
Conclusion
In concluding, we would emphasize two points. The first is that the
modern system has not only kicked away most of the constraints against
excessive risk taking but positively incentivizes systemic risk taking
in all manner of highly destructive ways. These include:
* The replacement of a monetary regime in which money managed
itself to one that requires management, leading to a central bank with a
proclivity to inflate the currency and engage in alternate policies of
boom followed by bust.
* The encouragement of excessive risk taking by a greatly expanded
LOLR function and by the destructive incentives created by federal
deposit insurance.
* The almost innumerable ways in which capital regulation, designed
to counter such risk taking, has exactly the opposite effects.
Underlying the LOLR function, deposit insurance, and financial
regulation generally, is a fundamental moral hazard issue--that each of
these, in different but reinforcing ways, incentivizes bankers to take
excessive risks because they reap the short-term benefits but offload
subsequent losses onto others, most notably, taxpayers.
Each of these features, and the problems they entail, reflects the
most fundamental point of all--namely, that the modern system of a
central bank and armies not only of regulators but of regulatory
bodies--has all but destroyed the old governance systems that used to
keep risk taking in reasonable check.
We have gone from a system that managed itself to one that requires
management but cannot be managed. We have gone from a system that was
guarded by market forces operating under the rule of law to one that
requires human guardians instead, but we have still not solved the
underlying problem of how to guard the guardians themselves.
The outstanding issue of the day is, therefore, very simple: how to
get back from here to there--preferably before the whole system
collapses. Abandoning bad ideas might be a good start.

(1) The etymology is also revealing. The English term
"regulate" comes from the late Latin regulat, meaning
"directed" or "controlled," but originates from the
Latin verb regulare, whose root is the noun regula or "rule."
(2) The role of the government in this crisis is highlighted by a
nice anecdote. Once the terms of the deal that was to end the crisis had
been agreed to by the bankers meeting in Morgan's library on
November 3, one of the participants advised him to consult President
Theodore Roosevelt about it. "But what has the president got to do
with it?" asked Morgan indignantly. He was then warned that the
centerpiece of the deal--the acquisition of Tennessee Coal & Iron by
U.S. Steel--was in violation of the Sherman Act and the deal would be
undermined unless the president agreed to waive any prospect of federal
prosecution, which Roosevelt then did. (See Bruner and Carr 2007:
131-33.) In other words, the government involvement in ending the crisis
of 1907 boiled down to it agreeing not to attack the deal by which the
crisis was resolved.
(3) This is not to suggest that U.S. bankers operated under
laissez-faire. They operated under severe amalgamation restrictions that
prevented interstate and even some intrastate banking. These rules
prevented banks from reaping the full benefits of economies of scale and
increased their vulnerability. They also operated under the legislative
restrictions of the National Banking System, which also created
considerable instability. By contrast, the contemporaneous Canadian
banking system was free of these restrictions and both much stronger and
more stable.
(4) We do not wish to single out Haldane for criticism. On the
contrary, he is almost alone among central bankers in having both the
intelligence and the courage to address the real problems that others
deny.
(5) There are various ways in which this could be done. Ideally,
one could roll back unlimited liability, at least for banks. Another
possibility, put forward by UK MP Steve Baker (Con, Wycombe) in 2012, is
to impose a regime of extended personal liability on bank directors,
with safeguards attached such as the requirement to post personal bonds
that would be forfeit if the bank got into difficulties. Critics might
argue that measures such as these would mean that banks would never
apply for assistance, but that is exactly the point: we don't want
them to.
(6) So the net effect of the Bagehot Rule was to provide a thin end
of the wedge by which the LOLR function had become its opposite, the
Bailout of First Resort. Old Bagehot must be turning in his grave.
(7) Note here the underlying "bad idea"--namely, that
there has to be a central bank LOLR function because the market on its
own can't provide emergency liquidity or its own LOLR. Yet this
idea flies in the face of the evidence that the market did provide its
own LOLR in the absence of a central bank--and this assistance was more
successful precisely because it was limited.
(8) For more on U.S. experiences with state deposit insurance, see
Calomiris (1989, 1990).
(9) Space precludes us from discussing some of the other ways in
which ill-judged policies contributed to this crisis. These include the
impact of Regulation Q combined with the highly inflationary Federal
Reserve policies of the late 1970s, which pushed many banks and thrifts
into insolvency. There was the impact of the increased deposit insurance
ceiling--raised from $40,000 to $100,000 in 1980--not to mention the
fact that the deposit insurance premium was at a flat rate rather than
risk-adjusted, which exacerbated the moral hazard associated with
deposit insurance. There was also the impact of regulatory forbearance,
in which regulators let insolvent institutions continue in operation in
order to avoid short-term strain on the deposit insurance fund, only to
result in larger losses later on.
(10) For a more extended treatment of these issues, see Dowd
(1992).
(11) An example is provided by Dowd (2000).
(12) We are not aware of estimates for the United States, but a
credible estimate for Europe puts the cost of Basel III at more than
70,000 full-time private sector jobs (Harle et al. 2010).
(13) This section draws on Dowd and Hutchinson (2010).
(14) This example is a perfect illustration of how the Basel system
tends to promote systemic instability. Going further, any weaknesses in
the Basel rules will have systemic potential. Any weakness in those
rules is likely to affect all banks at much the same time, whereas the
same weakness in any one institution's risk management will be
unlikely to have any systemic impact.
(15) The real issue is not harmonization at all: competing rule-
making systems tend to harmonize anyway. Instead, the real issue is the
process of harmonization. This is overlooked by the "planners"
who can only see one route to harmonization and have conveniently
hijacked the term itself. As they repeatedly argue, Who could be against
harmonization? But such propaganda misses the point.
(16) We are reminded of an anecdote about a senior Basel official
at one of the big risk conferences before the financial crisis.
Challenged to defend the (then) new Basel II rulebook of more than 1,250
pages of mind-numbing gobbledegook, he sighed and admitted, "It
does rather look as though it was written without adult
supervision."
(17) The regulators preferred to implement the Volcker Rule in a
"nuanced fashion," intending to distinguish between
intentional and unintentional prop trading, a barmy idea that would make
enforcement impossible unless a miscreant trader was considerate enough
to leave an incriminating e-mail trail. However, a "nuanced"
implementation does have the advantage of giving great scope for
discretion and enabling regulators to argue for more resources. Remember
that Volcker's original idea was for a simple rule that left no
exemptions and no room for ambiguity.
(18) This said, other rules serve the interests of the government.
The Basel zero weighting of OECD sovereigns is a case in point. This was
useful to governments because it artificially boosted the demand for
government debt.
