Following a U.S.-Israel attack on Iran in late February, the Strait of Hormuz has been effectively closed by Iranian authorities. In late June, after the nations agreed to a ceasefire, the International Maritime Organization announced an operation to evacuate over 600 trapped ships and more than 11,000 seafarers from the region. The evacuation effort was coordinated with Iran, Oman, other coastal states, the United States, and maritime industry representatives.
The evacuation plan directed vessels along a southern route hugging Oman’s coastline rather than the northern route along Iran’s coast. Initial progress saw over 100 ships depart, but operations halted after a Singapore-flagged cargo ship called the Ever Lovely was attacked while traversing the Omani-side route. Iran’s Revolutionary Guard criticized the evacuation effort for proceeding without Iranian coordination, asserting that only Tehran could determine which shipping routes vessels could use. Maritime observers characterized the resumption of shipping constraints as a frustrating reversal of progress.
Before the conflict, approximately one-fifth of the world’s oil and gas supply passed through the Strait of Hormuz. Analysts note that Iran now effectively controls the waterway, requiring coordination and clearance from Tehran for any vessel transit. However, international maritime law traditionally recognizes the strait as an international waterway critical to global economic activity. Legal and policy experts warn that allowing one nation to claim unilateral control over the passage contradicts longstanding freedom of navigation principles and could establish dangerous precedents for other strategic waterways globally.
Specialists point to concerns that other nations might claim similar authority over critical passages such as the Strait of Gibraltar, the Malacca Strait, or the Taiwan Straits, potentially imposing surcharges, restrictions, or using control as political leverage. Some waterways benefit from established management frameworks, such as the Montreux Convention governing Turkish Straits or cooperative agreements among Southeast Asian nations managing the Malacca Strait, but the Strait of Hormuz lacks comparable diplomatic protections. International maritime law instruments, including the U.N. Convention on the Law of the Sea, have limited enforcement capacity when nations decline ratification or adherence. Observers express concern about the adequacy of existing international mechanisms to protect freedom of navigation in contested waters.
