Stock Market Today: Dow Surges 1,200 Points, Oil Prices Fall On U.S.-Iran Cease-Fire (Live Coverage)

A U.S.-Iran cease-fire agreement triggered a historic 1,200-point surge in the Dow Jones Industrial Average, marking one of the largest single-day gains in recent years. Global oil prices plummeted following the cease-fire announcement, easing geopolitical tensions that had previously driven energy market volatility and supply chain concerns. The rally extended across major indices, with the S&P 500 and Nasdaq also posting significant gains as investor confidence rebounded amid reduced Middle East conflict risks. Analysts attributed the market reaction to immediate de-escalation, though warnings persist about long-term stability and potential residual economic impacts from prolonged tensions. The cease-fire’s timing in April 2026 coincides with broader economic uncertainty, raising questions about whether the market surge reflects lasting recovery or short-term relief.
