The S&P 500 suffered a severe 1.2% decline on Wednesday, with the selloff accelerating sharply during Federal Reserve Chair Kevin Warsh’s first policy meeting press conference.

The rout represents the worst opening-day performance for a new Fed chair in over three decades, underscoring immediate and intense market skepticism regarding the incoming leadership's trajectory.

The equity rout was not a broad-based macro liquidation but a targeted repricing of the new administration's monetary direction.

As Warsh took the podium, the index shed ground at an accelerating pace, signaling that traders are aggressively discounting the likelihood of a dovish pivot or a continuation of the previous Fed's gradualist approach.

The steepening losses during the press conference specifically highlight that the market is reacting to the chair's rhetoric and policy signals rather than just the rate decision itself.

This sharp negative debut places Warsh in historically difficult territory.
