The theme of the Federal Reserve Bank of Boston’s Economic Conference this year--reevaluating regulatory, supervisory, and central banking policies in the wake of the crisis--is certainly timely. Not much more than a year ago, we and our international counterparts faced the most severe financial crisis since the Great Depression. Fortunately, forceful and coordinated policy actions averted a global financial collapse, and since then, aided by a range of government programs, financial conditions have improved considerably. However, even though we avoided the worst financial and economic outcomes, the fallout from the crisis has nonetheless been very severe, as reflected in the depth of the global recession and the deep declines in employment both here and abroad. With the financial turmoil abating, now is the time for policymakers to take action to reduce the probability and severity of any future crises.

Although the crisis was an extraordinarily complex event with multiple causes, weaknesses in the risk-management practices of many financial firms, together with insufficient buffers of capital and liquidity, were clearly an important factor. Unfortunately, regulators and supervisors did not identify and remedy many of those weaknesses in a timely way.1 Accordingly, all financial regulators, including of course the Federal Reserve, must take a hard look at the experience of the past two years, correct identified shortcomings, and improve future performance.
