With Wall Street looking for any clues that tighter policy is coming, the Federal Reserve on Wednesday declined to raise interest rates or provide any clues about when a hike is on the way.

In a move widely expected on Wall Street, the U.S. central bank's Open Market Committee kept its key funds rate near zero. There had been some anticipation the FOMC would provide at least few code words indicating that it was ready to move, but there was scant evidence in the post-meeting statement.
