Any discussion about the costs and benefits of forward guidance must take place in the context of the situation in which it is being used. This brings me to my first case study, the Fed’s use of explicit time-based guidance starting on August 9, 2011. Despite extraordinary monetary stimulus—over 2½ years of near-zero short-term interest rates and QE1 and QE2—the unemployment rate had come down only 1 percentage point from its recession peak, to 9 percent, and the economic recovery remained tepid. Given the weakness in the economy, the FOMC repeatedly stated that it intended to keep rates exceptionally low “for an extended period.” Nonetheless, public expectations were glued to the idea that the Fed would start to raise rates in about a year.
It was against that backdrop that the FOMC decided to take dramatic action to shift public expectations using time-based forward guidance. The August 2011 FOMC statement said “The Committee currently anticipates that economic conditions—including low rates of resource utilization and a subdued outlook for inflation over the medium run—are likely to warrant exceptionally low levels for the federal funds rate at least through mid-2013.” Three comments are in order. First, this statement, as well as subsequent FOMC statements that used forward guidance, clearly put the economic outlook front and center as the determinant of policy. The outlook defines the guidance. Second, it was the lower bound that tied the hands of policymakers, not the introduction of date-based guidance. Third, this action was taken after weighing the concerns around the costs of time-based guidance discussed in Feroli et al. (2016); the conclusion then was that the benefits from stimulating the economy outweighed the potential cost.
The evidence bears out this judgment. The issuance of the statement dramatically shifted public expectations of future Fed policy. This is seen in private economists’ forecasts of the length of time until the Fed would raise rates, which jumped following the statement. Compared to the gentle taps of the hammer of previous FOMC verbal guidance that appeared to have little effect on expectations, the time-based guidance was like a sledgehammer.
