Fed's Rosengren sees 'at least' three rate hikes per year

The Federal Reserve may need to raise interest rates a bit more aggressively than the thrice-per-year pace forecast by Fed policymakers if the U.S. economy picks up steam as expected, a pragmatic Fed official said on Wednesday. Boston Fed President Eric Rosengren, a long-time dove who last year switched tack and began pushing for tighter monetary policy, said he expects the U.S. central bank to raise rates "at least as quickly" as the median Fed forecast from December.
