President Trump announced that the United States will reinstate a naval blockade of Iranian ports and establish a new fee structure for maritime traffic through the Strait of Hormuz. The blockade is scheduled to take effect on 16:00 Eastern Time Tuesday, with all cargo passing through the waterway subject to a 20% charge. Trump stated that while Iranian vessels and their customers would be restricted from the strait, all other nations would retain fair access to the passage.
The announcement followed military exchanges between US and Iranian forces in the region. The US conducted strikes against Iranian military infrastructure, including air defense systems and coastal radar installations. Iran responded by launching attacks on US military positions in Kuwait, Jordan, Bahrain, and radar facilities in Oman. Trump justified the new blockade and fee structure as necessary to ensure security in what he characterized as a volatile region, positioning the US as the guardian of the strait.
Iran’s Foreign Minister Abbas Araghchi responded by acknowledging that providers of maritime security should receive compensation, though he argued the 20% rate was excessive. He reasserted Iran’s historical role as the strait’s guardian. The International Maritime Organization, the UN agency overseeing global shipping regulations, stated there is no legal basis for imposing mandatory tolls for transit through international straits.
The practical implications of Trump’s announcement remain uncertain, particularly given international maritime law regarding territorial waters. The Strait of Hormuz at its narrowest point lies entirely within the territorial waters of Iran and Oman. The waterway is critical to global energy supplies, with approximately 25% of the world’s oil and 20% of liquefied natural gas previously flowing through it.
The blockade represents a resumption of earlier US actions. The US had previously imposed a blockade in April, which it lifted in June as part of a memorandum of understanding aimed at ending hostilities. Trump notified Congress on a recent Friday that the US had resumed military operations against Iran on 7 July. The announcement may face resistance from US allies concerned about the financial burden and potential complications for oil markets, which observers note were stable before recent hostilities commenced.
