St. Louis Federal Reserve Bank President James Bullard worried that the Fed's decision earlier this week to announce a plan to reduce bond buying was poorly timed, the regional Fed bank said in a statement on Friday explaining his dissent.
"President Bullard ... felt that the committee's decision to authorize the chairman to lay out a more elaborate plan for reducing the pace of asset purchases was inappropriately timed," the St. Louis Fed's statement said.
Bullard was one of two dissents cast on Wednesday by members of the U.S. central bank's policy-setting Federal Open Market Committee. The other dissent, by Kansas City Fed President Esther George, was in the opposite direction, as she worried that ongoing bond buying could stoke financial instability.
