Oil Price Impact

The 2026 Strait of Hormuz Crisis triggered the largest disruption to global energy supply since the 1970s Energy Crisis and the largest in the history of the global oil market. Brent crude prices surpassed $100/barrelon8March2026—thefirsttimesincethe2022RussianinvasionofUkraine—andpeakedat$126/barrel.

Oil exports from the Gulf region fell from 25 million barrels/day pre-war to approximately 10 million by 15 March — a 60% reduction. The IRGC’s closure affected roughly 13 million barrels/day of supply (accounting for pipeline rerouting), per ING analysis. QatarEnergy stopped gas production and declared force majeure on gas contracts on 4 March. Kuwait Petroleum Corporation, Bapco Energies (Bahrain), and Iraq all declared force majeure. Iraqi oil production at southern fields dropped 70% (from 4.3M to 1.3M barrels/day). By March 13, Saudi Arabia cut production 20% after two offshore fields including Safaniya were shut. The IEA’s 32 member states jointly released 400 million barrels from emergency reserves on March 11.

The market became acutely sensitive to every open/close signal from both sides — oscillating 9–12% on single announcements. On April 17, when Iranian FM Abbas Araghchi declared the strait “completely open,” WTI fell ~12% (to $83.85)andBrentfell9$90.38) in a single session. When Iran reversed this opening on April 18 and IRGC gunboats fired on ships, oil prices climbed back sharply. On April 19, US seizure of an Iranian cargo ship pushed prices to $96/barrel as markets reassessed the durability of any ceasefire arrangement. ING warned: “The physical market is becoming tighter every day that passes without a restart of oil flows through the Strait of Hormuz.”

Beyond oil, the crisis caused cascading commodity disruptions: European natural gas spiked from €30/MWh to a peak above €60/MWh in early March. Urea prices rose 50% by late March, as the Gulf produces ~50% of world urea and 30% of ammonia. About one-third of globally traded fertilizer normally transits Hormuz. Helium distributors began rationing (Qatar produces ~one-third of global helium). Aluminum prices rose as Gulf states produce 20% of raw aluminum. The fertilizer shock during spring planting season threatened to reduce 2026-2027 corn yields in the US and increase global food prices into 2027. California gasoline prices exceeded $5/gallon in mid-March. Slovenia became the first EU state to implement fuel rationing.
