Macroprudential Supervision and Monetary Policy in the Post-crisis World

Until two years ago, it was believed that the financial system as a whole was self-correcting and that modern tools of stabilization policy—monetary policy in particular—were sufficient to prevent severe economic contractions. We now know that we need a robust system of regulation and supervision that will recognize and prevent financial excesses before they lead to crisis, while at the same time maintaining an environment conducive to financial innovation. This address traces the causes of the crisis and the role of the Dodd-Frank Act in providing a framework for preventing recurrence. It then describes what must be done to identify emerging systemic financial risk, the tools and implementation of macroprudential financial supervision that must be developed, and the role of coordination between monetary policy and macroprudential supervision. Prevention of crises will not be easy—particularly because it will be necessary to walk a tightrope between prevention of catastrophe and keeping too tight a hold on the financial system.
