The Fed Richmond President, Jeffrey Lacker, said on Tuesday that June will be "the appropriate time" to hike interest rate in the U.S. as labour market and other conditions continued to improve.

He noted that headline inflation is likely to recover toward 2% this year.

The Fed Richmond president also said that he has not decided if he will dissent in case the FOMC officials should vote not to hike interest rates in a June policy meeting.

Lacker is a voting member of the Federal Open Market Committee this year.
