Republican presidential candidate Donald Trump would be inclined to replace Federal Reserve Chair Janet Yellen if he wins the White House despite supporting the U.S. central bank's efforts to keep interest rates low, he told Fortune magazine.

"I think she's done a serviceable job," Trump said in an interview published late on Tuesday, as the billionaire real estate mogul moved a step closer to becoming his party's nominee with a resounding win in the New York state nominating contest.

"I don't want to comment on reappointment, but I would be more inclined to put other people in."
