摘要：An examination of U.S. banking history shows that economically efficient private bank money requires that information-revealing securities markets for bank liabilities be closed That is, banks are optimally opaque, which is why they are regulated and examined.

The opacity of bank money in the recent financial crisis is also discussed.
