At the close of U.S. trading, the Dow Jones Industrial Average finished down 0.70%, the S&P 500 index fell 0.58%, while the Nasdaq Composite index fell 0.38%.
Fed language released earlier suggested monthly asset purchases will begin to taper soon, though uncertainty remained over the timing of such a decision, which sparked volatility in equities bourses Wednesday.
"Almost all participants confirmed that they were broadly comfortable with the characterization of the contingent outlook for asset purchases," the minutes read, adding two camps remain in place over the timing of tapering.
"A few members emphasized the importance of being patient and evaluating additional information on the economy before deciding on any changes to the pace of asset purchases. At the same time, a few others pointed to the contingent plan that had been articulated on behalf of the Committee the previous month, and suggested that it might soon be time to slow somewhat the pace of purchases as outlined in that plan."
