Strait of Hormuz, Iran
Hormuz is a contested shipping corridor where conflict, mines and blockades threaten commercial transit
The Strait of Hormuz is a major maritime route whose traffic has become a central pressure point in the conflict between Iran and the United States. Reporting dates the armed conflict to 28 February 2026, after which Iran closed the strait while the US maintained a strategic blockade of Iranian ports and vessels. Iran has also threatened vessels transiting without its authorisation and insisted that ships use the northern corridor through Iranian waters.
The waterway remains severely disrupted. US forces say they have cleared Iranian mines and helped 1,500 commercial vessels transit, carrying nearly 750 million barrels of crude oil. US strikes have targeted IRGC positions and rocket launchers near the strait, which Washington said were intended for laying mines. Iran has not commented on the clearance claims, while US allies doubt that the shipping lanes are mine-free. The UN reported 70 incidents since the war began, with 19 seafarers killed.
- Iran and the US are contesting access, with Iran imposing conditions and the US supporting commercial transits.
- Mine clearance is disputed: US commanders claim success, while allies still assess the strait as potentially mined.
- Traffic remains well below normal, despite US-supported movement of 1,500 commercial vessels.
- Reported incidents since the war began include attacks on vessels, with 19 seafarers killed.
- Watch Iran's enforcement of the northern corridor and any further US strikes near the waterway.
- Iran and Oman previously agreed in principle to administer traffic and discuss conditions for restoring normal flows.
