Oil Stocks Surge as Iran Conflict Fuels Supply Fears, with Exxon Leading Gains

Geopolitical unrest in the Persian Gulf is driving a sharp rally in energy stocks, led by Exxon Mobil (XOM), which gained 4.3% in early trading on March 9, 2026. The spike follows renewed threats of military escalation involving Iran and regional allies, raising concerns over potential disruptions to global oil flows through the Strait of Hormuz. Crude oil futures (CL=F) reached $98.70 per barrel, a 7.4% increase since the start of the month and the highest level since late 2023. The conflict’s impact extends beyond crude prices. Energy equities across the S&P 500 Energy Sector Index are up 6.1% over the past week, with major integrated majors like Chevron (CVX) and ConocoPhillips (COP) also posting double-digit gains. These moves reflect investor anticipation of sustained supply constraints, particularly if sanctions or naval blockades are expanded. Defense stocks have also seen a parallel uptick, with Lockheed Martin (LMT) and Raytheon Technologies (RTX) rising by 3.8% and 2.9%, respectively, amid increased defense spending expectations. Market volatility has intensified accordingly. The CBOE Volatility Index (^VIX) climbed to 21.6 on March 9, up from 19.3 a week earlier—a 12% rise that underscores investor unease. This volatility premium is being priced into options and equities, particularly in energy and defense sectors, where risk premiums are expanding. The sustained rally underscores a shift in market sentiment: while inflation concerns once weighed on equities, supply-side risks now dominate. With geopolitical risk premiums embedded in commodity and equity valuations, the energy sector remains a focal point for capital inflows. Should the crisis deepen, crude prices could breach $105 per barrel, further fueling gains in oil and defense stocks.
