St. Louis Federal Reserve President James Bullard said at a London event that the U.S. needs strong data backing its decisions if it wants to implement monetary policy independently of other global central banks, Reuters reported.

Bullard said the U.S. has historically tried to "go it alone," but the current global monetary policy environment requires data justification.

"If you want to go it alone in this environment you have to really have data that's coming in strong behind you and justifying what you want to do," Bullard said.
