The Fed Should Correct for Overconfidence in Its Review

In a speech Thursday, Federal Reserve Chair Jerome Powell hinted that the central bank’s five-year framework review will focus on the particulars of its maximum employment and stable price goals, as well as efforts to communicate clearly with the public. In both cases, the Fed should be guided by humility in the face of uncertainty.

The potential fracturing of the globalized trading system and a return to 1930s-style tariffs are developments that are expected to boost consumer prices and hurt growth in the US, but the propositions haven’t been tested in nearly a century. It’s impossible to know for sure whether price or growth effects will dominate — or whether some unforeseen third outcome will materialize.

After the last framework review in 2020, the Fed’s rate-setting committee famously implemented a policy based on the bold assumption that the future would look a lot like the past. Influenced by the so-so labor market and low inflation of the post-financial crisis period, the rate-setting committee agreed to target inflation that averaged 2% over time and to permit inflation moderately above that level following periods of persistently low price increases, based on the concept of flexible average inflation targeting. It also committed to reacting to perceived shortfalls in its maximum employment goal, but not necessarily to overshoots, despite the risks to inflation. When inflation took off in 2021 and 2022, critics said these principles had slowed the Fed down, and there appears to be a measure of truth to the criticism, despite Chair Powell’s denials.

That wasn’t the only error and maybe not even the primary one. Powell argued on Thursday — as he has in the past — that the mistakes of 2021 were largely the result of widespread forecast errors, both inside the Fed and beyond, rather than a conscious decision to allow consumer prices and the labor market to run hot. By and large, policymakers and forecasters initially viewed the 2021 inflation as an idiosyncratic supply shock — impacting just used cars and a few other items — and decided to look through the data that was staring them in the face. It was overconfidence in this narrow interpretation and the audacity to ignore the evolving data that ultimately led the Fed astray. The Fed’s goals should return to a simple 2% inflation target and maximum employment, but policymakers shouldn’t pretend that will solve all their problems.
