Inflation is likely to continue to ease and possibly allow the U.S. central bank to cut interest rates sooner and faster than expected, Federal Reserve Governor Christopher Waller said on Thursday in comments that pushed against recent market moves that anticipate a shallower Fed rate path.

Outside of a U.S. President bending norms, the Fed also faces challenges in achieving its economic objectives. Inflation remains above its 2% target: Its preferred measure is at 2.4%, though core prices — considered a better gauge of where inflation is headed — rose 2.8% in November from a year ago.
