U.S. Stocks Rally After Iran Strikes Spark Energy Volatility, Dip Buyers Step In

U.S. stock indices reversed course after opening lower, driven by a surge in buying interest amid escalating tensions in the Middle East. The conflict intensified on March 8, 2026, when Iranian forces launched missile strikes in response to U.S. and Israeli air raids targeting an oil depot in Tehran on February 28. The attacks reignited fears of supply disruptions in global energy markets, particularly affecting crude oil flows through the Strait of Hormuz. The benchmark Brent crude futures, tracked via CL=F, jumped 6.4% to $98.30 per barrel, reflecting heightened risk premiums. This spike in energy costs also boosted defense-related equities, with stocks in aerospace and defense firms showing strong gains. Meanwhile, the CBOE Volatility Index (^VIX) rose to 28.7, up 15% from the prior session, signaling increased market anxiety over potential supply shocks. Despite the geopolitical flare-up, major indices showed resilience. The S&P 500 ended the day up 1.2%, while the Nasdaq Composite gained 1.8%, led by technology names such as Apple (AAPL), which rose 2.3% as investors sought quality assets amid uncertainty. The rally was fueled by dip buyers stepping in after early afternoon losses, betting on a short-term rebound once initial panic subsided. The broader market reaction underscores the dual impact of regional conflict: while energy and defense sectors benefit from elevated risk, broader equity markets can stabilize if disruptions remain contained. Investors are now closely monitoring developments in the Middle East, particularly Iran’s next moves and the potential for further escalation involving regional allies.
