William Dudley, head of the New York Fed, and John Williams, head of the San Francisco Fed, both signaled support for an interest rate hike this year, saying they expect inflation to rise towards the Fed’s 2-percent target. Williams sounded more hawkish, saying that just “a little bit” more data could convince him that a rate hike is needed. The Fed’s 17 policymakers have scheduled 16 separate speeches or public appearances this week across the country, less than two weeks after the central bank decided to delay what would be its first rate hike in nearly a decade.
