US Stocks End Mixed as Iran Attack Pause Eases Oil Prices

U.S. stock markets closed with mixed results on Monday, July 27, 2026, as tensions between the United States and Iran eased following a reported pause in military operations. The Dow Jones Industrial Average rose 0.5% to 52,210.08, while the S&P 500 was nearly flat, up less than 0.1% to 7,413.18. The Nasdaq composite declined 0.2% to 24,932.08, weighed down by a 5% drop in Nvidia. The Russell 2000 index of smaller companies outperformed, rising 0.6% to 2,948.03.

The market rally was driven by eased geopolitical tensions after the U.S. military paused attacks on Iran and both sides signaled interest in resuming negotiations to end their conflict. According to reporting, President Trump ordered U.S. forces to halt new attacks on Iran on July 24. Iranian officials subsequently indicated that if the U.S. did not attack, Iran would also cease attacks. This temporary cessation of military operations reduced immediate concerns about energy supply disruptions in the Middle East, which had pushed oil prices to $102 per barrel the previous week.

Oil prices fell sharply in response to the de-escalation. Brent crude dropped 6.3% to settle at $85.87 per barrel, while West Texas Intermediate crude fell approximately 6% to around $84 per barrel. The decline in oil prices supported overall market sentiment, as lower energy costs ease inflation concerns and benefit consumers. Treasury yields also fell, with the 10-year yield declining to approximately 4.65% from 4.67% the previous week.

Equities showed divergent performance within major indices. Technology stocks including Microsoft, Salesforce, and Alphabet posted gains, while Nvidia, Caterpillar, and Chevron declined. During intraday trading, the Dow had risen as much as 608 points. Market attention is now focused on the U.S. Federal Open Market Committee (FOMC) meeting scheduled for July 28-29, where investors are seeking clarity on the future direction of monetary policy. A pause in interest rate changes is widely expected.
