Stocks Fall as Fed Nominee Backs Rollback; Trump Extends Truce

U.S. stock indexes tumbled on April 21 after Federal Reserve nominee Kevin Warsh told senators he supports reducing the central bank's elevated balance sheet and reports emerged that planned U.S.-Iran diplomatic talks in Islamabad had been canceled. President Trump announced a ceasefire extension after markets closed.

At a Senate confirmation hearing in Washington, Warsh affirmed the need to move away from an expanded balance sheet and defended the Fed's independence. His comments pressured equities early in the session as traders reassessed the outlook for monetary policy.

Late in the trading day, reports said Iranian negotiators were reluctant to finalize the Islamabad talks ahead of a ceasefire deadline at midnight Pakistan time on April 22. The diplomatic setback removed a market catalyst that had supported recent gains.

The combination of the Fed remarks and the diplomatic reports triggered a rapid late-session selloff. Algorithmic and institutional desks moved to reduce risk, pushing major U.S. indexes to intraday lows by the close. Crude oil prices rose on heightened geopolitical uncertainty. The dollar initially strengthened on Warsh's comments, then slipped after the White House announced the ceasefire extension. The New Zealand dollar gained following a surprise pickup in domestic inflation data.

Metals and several European equity markets registered larger declines than the U.S. market, reflecting adjustments to the diplomatic outlook. Consumer-focused companies are scheduled to report second-quarter projections and April earnings on April 22, and market participants said those results will offer additional information on demand and margins.

Traders reported that thin liquidity and automated order flow amplified the late-session price moves, accelerating selling in the final minutes. After the market close, the White House statement extended the ceasefire but did not include a detailed schedule for renewed talks; futures recovered some losses on that announcement.

No direct quotes from Warsh or Iranian negotiators were included in initial reports. Investors said they will watch for further updates from Islamabad and for additional remarks during the confirmation process to assess the likely path for balance-sheet normalization and the implications for markets.
