In many advanced countries, lowering the policy rate to zero will be insufficient to counter the next recession. In the United States, for example, with the target range for the federal funds rate at 1½ to 1¾ percent, there is little scope for the nearly 5 percentage-point easing that is typical in recent recessions (see, for example, Kiley).

This is the setting for this year’s report for the U.S. Monetary Policy Forum, written with Michael Feroli, Anil Kashyap and Catherine Mann. Our analysis focuses on the extent to which the “new tools” of monetary policy—including quantitative easing, forward guidance and negative interest rates—have been associated with an improvement of financial conditions. The idea is that the transmission of monetary policy to economic activity and prices works primarily through its effect on a broad array of financial conditions.

The USMPF report does not challenge the views of many researchers and of most central banks that the new monetary policy (NMP) tools have an expansionary impact even at the effective lower bound for nominal interest rates (see also the 2019 report from the Committee on the Global Financial System). However, we find that these new tools generally were not sufficient to overcome the powerful headwinds that prevailed in many advanced economies over the past decade.

Our conclusion is that central bankers should clearly incorporate the new tools in their reaction functions and communications strategies, but should be humble about their likely success in countering the next recession, at least in the absence of other supportive actions (such as fiscal stimulus)….
