Iran's claim of exclusive control over the Strait of Hormus raises alarms over global oil transit and heightens risk of supply disruptions

Iran asserted exclusive control over the Strait of Hormus amid renewed US‑Iran hostilities. The strait carries about 30% of global oil shipments; any disruption could spike energy prices and affect global markets. Iranian government, United States military, Gulf states (Bahrain, Kuwait), international shipping industry. Possible US or allied naval escort missions, UN Security Council discussions, and short‑term oil price volatility. On June 28, 2026, Iranian officials renewed their demand for sole authority over the Strait of Hormus, a vital chokepoint for roughly one‑third of the world’s seaborne oil trade. The statement follows a series of reciprocal military strikes between the United States and Iran in the Gulf region, which have heightened fears of a broader confrontation. Analysts warn that any attempt to restrict passage could trigger spikes in crude prices, higher insurance premiums for tankers, and potential international diplomatic or military responses. The situation remains fluid, with both sides signalling readiness to defend their positions.
