Fed’s Yellen sees rate hikes ahead, but few hints on when

Federal Reserve Chair Janet Yellen Monday gave a largely upbeat assessment of the U.S. economic outlook and said interest rate hikes are coming but, in an omission that stood out to some investors, gave little sense of when.

To some investors, the absence of a timeframe in Monday’s remarks suggests the Fed will delay its next rate hike well beyond next week, when U.S. central bankers next gather to make monetary policy.

To others, Yellen’s repeated emphasis on the positive aspects of recent economic data continues to suggest a rate hike in the near future.

The U.S. central bank raised rates from near zero in December in the first U.S. policy tightening in nearly a decade.
