Federal Reserve: When will it raise interest rates?

US markets have surged on the Federal Reserve's vote of confidence in the strength of the economy.

The bank kept interest rates on hold, but dropped a key pledge to remain patient about future rate rises.

The Fed indicated that it could move as early as June, but there's no guarantee it will happen that early.

The BBC's Michelle Fleury attempts to decode the central bank's statement to get a better sense of when a rate rise might occur.
