The Fed may have to raise rates faster than current projections indicate, Boston Fed Eric Rosengren said on Friday. 

"My own view is that if the unemployment rate falls as much as I'm expecting, then it is possible that we'll have to raise rates faster than the summary of economic projections," Rosengren, a hawkish member of the Federal Open Market Committee, told CNBC. 

Rosengren anticipated the unemployment rate to decline to 4.5% next year, an unsustainable level that may force the Fed to act. Current projections put interest rates at just above 1% by the end of next year. Another rate hike at the December meeting is widely expected.
