Philadelphia Federal Reserve Bank President Patrick Harker on Monday said he would be open to raising interest rates again at the U.S. central bank's March meeting if growth in jobs and wages continues. "I still am supportive of three rate hikes this year, of course with a major caveat, depending on how the economy evolves and policy, fiscal policy, evolves," Harker told reporters after a speech on the regulation of fintech firms." I think March should be considered as a potential for another 25-basis point increase." The Fed raised rates for only the second time since the financial crisis in December, and most Fed policymakers agree with Harker that three more rate hikes this year would be appropriate. Wall Street banks and interest-rate futures traders are betting the Fed will only lift borrowing costs twice this year, starting in June.
