Fed Chairwoman Janet Yellen said last week she still expects to raise interest rates this year if the economy meets her forecasts, with a gradual pace of tightening to follow. The core US consumer-price index rose 0.3 per cent in April, the biggest gain since January 2013, a Labor Department report showed on Friday.
US employment rebounded last month after faltering in March, a sign the world's biggest economy may be regaining momentum after stagnating early this year.
Recent figures suggest the economy's setback in the first quarter was "transitory," Mester said, adding that she's "reasonably confident" that inflation is heading toward the Fed's 2 per cent target in the medium term.
In her speech, Mester said an extended period of "essentially zero" interest rates may pose risks to financial stability. "I do think that when we are making policy decisions, we should be cognizant of the linkages between our nonconventional monetary policy of an extended period of essentially zero interest rates and financial stability."
Mester said it's "very important" the Fed retain its independence in setting monetary policy. "The Congress in the US gives us our goals," she said. "We're held accountable to the American public.''
The Fed has been under increasing congressional pressure to say more about how it conducts monetary policy and bank supervision. The Senate Banking Committee last week approved legislation that would require the Fed to disclose more information to Congress about monetary policy decisions, and make the head of the Federal Reserve Bank of New York subject to confirmation by the Senate.
