Powell said Wednesday that the central bank is "strongly committed" to bringing down inflation and can do so with its monetary policy tools.
He also said that the Fed is not trying to provoke a recession by rate hikes, but it may be a possibility.
The remarks came one week after the U.S. central bank delivered the largest interest rate hike since 1994 in an effort to combat inflation that is running at a four-decade high.
