Asian stocks stumbled and the dollar stood tall on Thursday after minutes from the U.S. Federal Reserve's October meeting hinted at stimulus tapering, while the euro was pressured by speculation of more easing by the European Central Bank.
Federal Reserve officials indicated at the bank's Oct. 29-30 policy meeting that they could decide to start scaling back the asset purchases at one of its next few meetings provided this was warranted by economic growth.
"The headline that most participants saw tapering in the next couple of meetings cannot be much of surprise, since the alternative is a virtual indefinite postponement," said Steven Englander, global head of G10 FX strategy at CitiFX.
"That said, the 5 percent probability associated with a December tapering seemed too low so there may have been an unwinding of somewhat overly dovish expectations," Englander wrote in a note to clients.
