Boston Fed President Eric Rosengren said on Monday that it is not right time for hiking interest rate.

"The conditions for beginning the tightening of monetary policy have not yet been met," Rosengren said.

Boston Fed president noted that there is only a little sign of a rebound.

"The data have disappointed before, and an appropriately data-dependent monetary policy requires confirmation in the numbers, not just in forecasts of better times," Rosengren said.

Rosengren is not a voting member of the Federal Open Market Committee this year.
