Crude oil prices climbed above $79 per barrel on Thursday, driven by a confirmed attack on a commercial tanker linked to Iran, intensifying regional tensions and triggering a sharp market response. The move marks a 15% weekly increase and reflects growing fears over Middle East supply security.

U.S. crude oil futures (CL=F) breached $79 per barrel on March 5, 2026, following a reported attack on a merchant tanker in the Strait of Hormuz, with multiple intelligence assessments attributing the strike to Iran. The incident escalated longstanding regional tensions between Tehran and Western powers, prompting immediate reactions from global energy markets. The 15% surge in crude prices over the past five days represents one of the most abrupt spikes in energy markets since 2022, underscoring investor concerns over potential disruptions to global oil flows. The volatility index (VIX) jumped 22%, reflecting heightened market anxiety, while the energy sector ETF (XLE) rose 6.3% on the day, signaling a broad-based risk premium being priced in. The attack targeted a vessel operated under a flag of convenience, though no casualties were reported. Nevertheless, the incident prompted the U.S. Department of Defense to enhance naval patrols in the Persian Gulf and the Red Sea, increasing the risk of spillover conflict. Shipping insurers have begun reviewing coverage for vessels transiting high-risk zones, while major oil traders are reassessing supply chain routes. Energy analysts warn that sustained instability in the region could lead to a prolonged supply premium, with Brent crude potentially reaching $87–$90 per barrel if diplomatic resolution stalls. The situation remains fluid, with international diplomatic channels actively engaged to de-escalate tensions.
