Hormuz Status June 2026: Limited Reopening Under US Navy Watch

The Strait of Hormuz remains one of the most contested chokepoints in global trade as of early June 2026. Roughly a fifth of the world's seaborne oil and large volumes of liquefied natural gas, fertilizers and containerized goods normally pass through this 34 kilometre wide passage between Iran and Oman. The waterway has been effectively shut to most foreign traffic since 28 February 2026, when Iran closed it in response to the start of the war with the United States and Israel. Months later the situation has shifted from a near total blockade toward a fragile and partial reopening, driven largely by the US military.

The American effort began as a high profile operation and has since moved into a quieter, more sustained phase. In early May the United States launched a formal escort mission to push commercial vessels through the strait. The operation ran for roughly one day on 4 and 5 May before being paused while Washington assessed the chances of a wider agreement with Tehran. During that brief window several Iranian fast boats were sunk and at least one French operated container ship was struck, underlining how dangerous the corridor remained.

Since late May the US approach has changed. Rather than running visible convoys, US Central Command has established a marked pathway along the Omani side of the strait and now supports merchant ships mainly through communication and coordination. Navy guided missile destroyers have charted a route and provide what officials describe as distant protection using destroyers, attack aircraft and helicopters positioned near Omani waters. CENTCOM has been careful to state that its assets are not formally escorting vessels but are advising commercial crews on how to cross safely.

The results of this quieter strategy are visible but limited. Of the 109 larger tankers, those able to carry 700,000 barrels or more, that were trapped inside the Gulf when the strait closed on 28 February, 29 had successfully crossed the chokepoint by the end of May according to shipping data. Some vessels received helicopter escorts during their transit. At least two shipowners have confirmed they were in direct contact with US forces who guided them through the passage. The chief executive of Maersk, one of the world's largest shipping lines, praised the American operation that moved one of its ships through the strait, calling it a very well executed mission.

Despite these successes, the corridor is far from fully open. The large majority of stranded tankers, around 80 of the original 109, were still waiting as of early June. Many shipping companies remain unwilling to risk the crossing even with US support, and insurance and security concerns continue to keep traffic far below prewar levels. Brent crude has stayed more than 30 percent above its prewar price, and the US average gasoline price climbed well above 4 dollars per gallon during the spring.

A second source of friction is Iran's parallel system of control. Tehran has set up a body it calls the Persian Gulf Strait Authority and published a map claiming a management zone that reaches deep into waters the United Arab Emirates and Oman regard as their own. Iran has warned that vessels must obtain permission before transiting and has threatened to destroy ships that cross without authorization. Some vessels have reportedly continued to use the Iranian controlled route and faced demands for payments said to reach as high as 2 million dollars per ship. Iranian officials deny charging tolls but argue that navigation, security and environmental services will carry fees.

Oman sits at the centre of this dispute. The sultanate controls the southern shore of the strait, and the US established its safe corridor largely within Omani waters. Iran has discussed setting up a joint toll mechanism with Oman to charge transiting vessels, a plan first reported in connection with talks between the two states. Washington reacted sharply. The US Treasury Secretary said Oman's ambassador assured him the sultanate has no plans to impose any crossing fee, and warned that the Treasury would aggressively pursue anyone involved in collecting or disguising tolls. The United States went on to sanction Iran's Strait Authority, with the Treasury chief dismissing it as illegitimate. Five Gulf states have separately warned shipping companies through the International Maritime Organization not to comply with Iran's claimed zone, and the UN shipping body has cautioned that any toll on an international strait would set a dangerous precedent.

The diplomatic backdrop has worsened in recent days. Iran has suspended its negotiations with the United States in protest at Israeli military operations in Lebanon and has renewed its threat to close the strait entirely. A draft UN Security Council resolution demanding the reopening of Hormuz has broad support but faces resistance from Russia and China.

As of early June 2026 the strait is therefore neither closed nor truly open. A narrow, US backed pathway exists along the Omani coast and has allowed a slow trickle of tankers to escape the Gulf, but the bulk of trapped vessels remain in port, the Iranian controlled route still operates under threat of force and possible charges, and the underlying conflict remains unresolved. The coming weeks will determine whether traffic recovers further or whether renewed Iranian threats push the chokepoint back toward full closure.
