US equities closed lower on Wednesday as investors digested the Federal Reserve's decision to keep interest rates unchanged, a move overshadowed by significant internal dissent.

The central bank maintained its benchmark federal funds target in the 3.50% to 3.75% range, marking the fifth consecutive meeting without a rate adjustment.

However, the unanimity of previous decisions was broken, with three of the 12 FOMC members voting in favor of a 25 basis point increase.

This split highlights growing concern among policymakers about persistent inflationary pressures and the potential need for further tightening.

The hawkish dissent weighed on risk assets, contributing to the downward pressure on US stocks.

Markets are now recalibrating expectations for the policy path, with the dissent suggesting that the Fed's pause may be shorter than previously anticipated.
