Crude oil prices surged to their highest levels in four years as escalating U.S.-Israeli military operations against Iran led to the effective closure of the Strait of Hormuz, triggering a major supply shock. The benchmark CL=F contract climbed over 12% in a single session, while volatility spiked on the VIX.
- CL=F surged 12.3% on March 1, 2026, reaching $118.20/barrel
- Strait of Hormuz effectively closed due to U.S.-Israel-Iran military escalation
- ^VIX spiked 28% amid rising market uncertainty
- Over 20 million barrels per day of global oil exports pass through the Strait of Hormuz
- Energy stocks including XOM and CVX rose over 6% on heightened risk premiums
- Potential for crude prices to reach $130/barrel if closure persists beyond 10 days
Global crude markets plunged into turmoil on March 1, 2026, as the Strait of Hormuz—through which nearly 20 million barrels per day of oil traditionally flows—was rendered effectively inoperable due to intensified military activity between the U.S., Israel, and Iran. The closure, confirmed by multiple shipping tracking sources, has disrupted one of the world’s most critical energy chokepoints, significantly raising the risk of a severe supply shortage. The benchmark West Texas Intermediate (CL=F) futures rose by 12.3% in the session, marking the largest single-day gain since early 2022. This surge pushed the contract above $118 per barrel, a level not seen since late 2022. The broader energy sector responded with immediate volatility: the CBOE Volatility Index (^VIX) jumped 28%, signaling heightened market anxiety over supply chain disruptions and potential escalation. With over 30% of global oil exports passing through the Strait of Hormuz, the disruption has prompted emergency stockpile drawdowns by several nations, including the United States and Japan. OIL ETFs and energy equities saw sharp gains, led by major integrated producers such as ExxonMobil (XOM) and Chevron (CVX), which rose over 6% on the day. Analysts warn that sustained closure could push crude prices toward $130/barrel if no alternative shipping routes are established within the next 10 days. The defense sector also reacted, with defense contractors including Lockheed Martin (LMT) and Raytheon Technologies (RTX) seeing increased trading volume as geopolitical tensions escalated. The international community is now assessing contingency plans, including naval escorts and rerouting via the Cape of Good Hope, but such measures would add significant time and cost to deliveries.
