A top Federal Reserve policymaker signaled Friday that despite a “nearly healed” U.S. labor market, he will not support raising U.S. interest rates until he sees stronger signs of inflation. “Until I have more confidence that inflation will be moving back to 2 percent, I’ll continue to be in wait-and-see mode regarding raising interest rates,” San Francisco Federal Reserve President John Williams said in remarks prepared for delivery to the NBER East Asia Seminar on Economics.
