The Fed Can’t Ignore All of Trump’s Intentions

When US Federal Reserve Chair Jerome Powell faces the media after the central bank’s policy-making meeting next week, he’ll probably get a politically fraught question: How will the Fed incorporate president-elect Donald Trump’s stated plans — including tax cuts, tariffs and deportations — into its economic outlook and monetary policy?

In November, Powell’s response was categorical: “We don’t guess, we don’t speculate, and we don’t assume.” This time around, he’ll have to be more nuanced.

In fact, the Fed can and must at times make assumptions about what politicians will do. Back in December 2016, when I was vice chairman of the policy-making Federal Open Markets Committee and Trump had just been elected to his first term, the staff forecast assumed that “Congress will pass a personal income tax reduction worth 1 percent of GDP, to begin in the third quarter of next year.”

At the time, I asked the staff a question similar to what Powell will likely get: “What’s the threshold for deciding to put something in for trade barriers going up or immigration policy being tightened?” Based on the answer then and my experience at the Fed, I see four criteria.

First, there has to be a strong likelihood that a policy shift will take place.

Second, the shift must be large enough to have meaningful consequences for economic growth, employment, inflation or financial conditions, including stock prices and interest rates.

Third, the Fed needs some clarity about what the policy will be. In December 2016, potential tariffs weren’t incorporated in the forecast. As Steve Kamin, then head of the Fed’s Division of International Finance, put it, the possibilities were “so disparate” and their magnitude “so difficult to gauge” that the staff “chose not to assume.”
