At the presidential debate on Sept. 26, Republican candidate Donald Trump accused Federal Reserve Chair Janet Yellen of inflating “a big, fat, ugly bubble” by keeping interest rates too low. Yellen couldn’t just shrug off the accusation, because only five days earlier three members of her own rate-setting group, the Federal Open Market Committee, had expressed the same idea in more delicate language. Loretta Mester, Esther George, and Eric Rosengren dissented from the FOMC decision to stand pat on rates, the committee announced, because they “preferred” to raise the federal funds rate a quarter percentage point at the meeting.
