"With the unemployment rate near 50-year lows and inflation likely to rise toward the 2 percent target, and with financial stability concerns being somewhat elevated given near-record equity prices and corporate leverage, I do not see a clear and compelling case for additional monetary accommodation at this time," Rosengren said in a statement.

Under the Fed's communications policy, Friday is the first day after a Fed rate-setting decision that Fed Chairman Jerome Powell's colleagues are permitted to air their views.

Rosengren did not make any reference to trade uncertainty or to newly imposed tariffs that on Thursday prompted traders to price in expectations for two more rate cuts this year, and more in 2020. Powell cited trade uncertainty as one reason the Fed had decided to cut rates.
