Team Transitory is throwing in the towel.

In a clear sign that the U.S. Federal Reserve is shifting to tighter monetary policy, Jerome Powell — who’s spent months arguing that the pandemic surge in inflation was largely due to transitory forces — told Congress on Tuesday that it’s "probably a good time to retire that word.”

The Fed chair, tapped last week for another four-year term, still thinks inflation will ebb next year. But in testimony before the Senate Banking Committee, he acknowledged that it’s proving more powerful and persistent than expected, and said the Fed will consider ending its asset purchases earlier than planned.
