While annual inflation may have peaked, it remains at levels we last saw in the early 1980s. Indeed, our preferred measure of the medium-term inflation trend– the six-month annualized change in the trimmed mean personal consumption expenditure price index—is up by nearly 5 percent. Fortunately, policymakers now realize the severity of the situation and are raising interest rates quickly as they work to catch up. Fed fund futures anticipate a rate of at least 3½ percent by yearend—the most rapid increase in more than 40 years. Will this be enough?

In this post, we address this question. Our conclusion is that policymakers will have to act more aggressively than financial markets anticipate if inflation is to decline to the Fed’s 2-percent target within two years. The reason is that inflation has substantial forward momentum arising from two sources. First, a tight labor market combined with elevated short-term inflation expectations appear poised to drive wage inflation higher. Second, there is the continuing impact of increases in prices of housing, both for owners and renters.
