This expansion of the scope and scale of Fed lending may not have been so large had we had better resolution mechanisms to deal with such failing firms as Bear Stearns and AIG. And perhaps our lending would not have become so wide-ranging had there been better regulation or more resiliency in the payment and settlement systems, including more transparency about the markets for mortgage-backed securities and credit default swaps.

Some may think access to the Fed's lending facilities should be permanently expanded to include a wide range of financial institutions. I believe such expanded access to central bank credit would raise significant issues of moral hazard that would need to be addressed. And I have urged that we must continue to avoid compromising the Fed's independence — one of the great strengths of central banks.
Some people might think that expanding the Federal Reserve's regulatory and supervisory authority and giving it a sweeping mandate for financial stability would prevent the types of financial crises we have been experiencing this year. That is unrealistic.

Going forward our focus should be on better regulation, not necessarily more regulation. We need to focus on ways to strengthen our financial markets to make market discipline more effective at mitigating systemic risk. We should think about which financial markets are critical to the efficient functioning of the payment system rather than focusing on individual firms. Ideally, we need to determine which aspects of the financial system are critical and then make sure we have the market mechanisms, regulations, and supervision to ensure those sectors are resilient.
