Fed Chair Kevin Warsh’s Policy Shift Fuels US Stock Market Moves

Kevin Warsh was sworn in as the Federal Reserve’s 17th chair on May 22, succeeding Jerome Powell. In testimony before the Senate Banking Committee, Warsh warned of a “regime change in the conduct of policy,” signalling a move away from the Fed’s long‑standing predictability, a smaller balance sheet and a more flexible inflation definition.

The market responded with a mixed day on June 4. The Dow Jones Industrial Average reached a fresh record high as investors rotated into healthcare, financials, retail and small‑cap stocks, while the Nasdaq Composite slipped after Broadcom’s shares fell about 14% on a miss of AI‑chip sales expectations. The broader S&P 500 rose modestly, but technology and semiconductor indices posted losses. Traders priced in a roughly 75% chance of a 25‑basis‑point rate hike at Warsh’s first policy meeting later that month, reflecting heightened scrutiny of the new chair’s monetary stance.

Analysts noted that the shift away from aggressive AI‑driven equity rallies toward more traditional sectors could persist if Warsh pursues a tighter monetary stance and balance‑sheet reductions, potentially reshaping borrowing costs and market dynamics in the coming months.
