Bernanke on the financial system, reserves, risk
"At the same time that we are addressing such immediate challenges, it is not too soon for policymakers to begin thinking about the reforms to the financial architecture, broadly conceived, that could help prevent a similar crisis from developing in the future. We must have a strategy that regulates the financial system as a whole, in a holistic way, not just its individual components. In particular, strong and effective regulation and supervision of banking institutions, although necessary for reducing systemic risk, are not sufficient by themselves to achieve this aim.
"Today, I would like to talk about four key elements of such a strategy. First, we must address the problem of financial institutions that are deemed too big--or perhaps too interconnected--to fail. Second, we must strengthen what I will call the financial infrastructure--the systems, rules, and conventions that govern trading, payment, clearing, and settlement in financial markets--to ensure that it will perform well under stress. Third, we should review regulatory policies and accounting rules to ensure that they do not induce excessive procyclicality--that is, do not overly magnify the ups and downs in the financial system and the economy. Finally, we should consider whether the creation of an authority specifically charged with monitoring and addressing systemic risks would help protect the system from financial crises like the one we are currently experiencing."
Regarding mark-to-market accounting, which some banking industry officials claim is the root of all evil, Bernanke has the following to say (I've already weighed in here):
"The ongoing move by those who set accounting standards toward requirements for improved disclosure and greater transparency is a positive development that deserves full support. However, determining appropriate valuation methods for illiquid or idiosyncratic assets can be very difficult, to put it mildly. Similarly, there is considerable uncertainty regarding the appropriate levels of loan loss reserves over the cycle. As a result, further review of accounting standards governing valuation and loss provisioning would be useful, and might result in modifications to the accounting rules that reduce their procyclical effects without compromising the goals of disclosure and transparency. Indeed, work is underway on these issues through the Financial Stability Forum, and the results of that work may prove useful for U.S. policymakers."
