摘要：In early 2006 nine Eurosystem central banks – the national central banks (NCBs) of Belgium, Germany, Spain, France, Italy, the Netherlands, Portugal and Finland, as well as the European Central Bank (ECB) – established a task force to analyse and discuss the use of portfolio credit risk methodologies by central banks. The objectives of the task force were threefold. The first was to conduct a stock-taking exercise as regards current practices at NCBs and the ECB. The second followed directly from the first: to share views and know-how among participants. The third was to develop or agree on a “best practice” for central banks on certain central bank-specific modelling aspects and parameter choices. Two common portfolios were analysed by several task force members with different systems and the simulation results were compared. This report summarises the findings of the task force. It is organised as follows. Section 2 starts with a discussion of the relevance of credit risk for central banks. It is followed by a short introduction to credit risk models, parameters and systems in Section 3, focusing on models used by members of the task force. Section 4 presents the results of the simulation exercise undertaken by the task force. The lessons from these simulations as well as other conclusions are discussed in Section 5.
