Iran Restricts Strait of Hormuz Access to US and Israeli Vessels Amidst Rising Tensions

March 15, 2026 – Iranian Foreign Minister Abbas Araghchi announced Saturday that the Strait of Hormuz remains open to all nations except the United States and Israel. This declaration comes as tensions escalate in the region following recent US military action against Iranian targets and amid ongoing concerns about the security of vital oil shipping lanes.

Strategic Importance of the Strait of Hormuz

The Strait of Hormuz is a critical chokepoint for global energy supplies, with approximately 20% of the world’s crude oil passing through the narrow waterway. Control over the Strait allows Iran significant leverage in regional and international affairs.

Iran’s Restrictions and Justifications

According to Araghchi, the restrictions are limited to vessels belonging to the US, Israel, and their allies, which he characterized as “enemies” actively attacking Iran. “As a matter of fact, this Strait of Hormuz is open. It is only closed to the tankers and ships belonging to our enemies, to those who are attacking us and the allies. Others are free to pass,” he stated in an interview with MS NOW.

Despite the restrictions, Araghchi asserted that many ships “prefer” not to transit the Strait due to “security concerns,” but maintained that these concerns are unrelated to Iranian actions.

Recent Ship Transits and Regional Impact

Recent reports indicate that vessels from India have safely transited the Strait of Hormuz. However, the situation has prompted the US and its allies to release 400 million barrels of strategic oil reserves in an attempt to stabilize crude oil prices, which have risen sharply in response to the increased tensions. WTI crude oil is currently trading at $98 per barrel, while Brent crude has reached $103 per barrel.

Escalating Conflict and Security Concerns

Iran has claimed responsibility for several attacks on ships in and around the Strait of Hormuz, including an incident involving a Thai vessel. The Islamic Revolutionary Guard Corps has previously stated that any ship seeking passage through the Strait must obtain permission from Iran.

The Iranian Revolutionary Guard has similarly warned people across the Gulf to evacuate areas near oil ports.

International Response

US President Trump has threatened to destroy Iran’s oil infrastructure on Kharg Island, a critical energy hub through which 90% of Iran’s oil exports pass, should Iran continue to impede safe passage through the Strait.
