Iran’s Islamic Revolutionary Guard Corps (IRGC) has declared that any ship passing the Strait of Hormuz must first obtain official approval. Rear Admiral Alireza Tangsiri, commander of the IRGC Navy, warned that vessels ignoring Iran’s directives could face attacks. This announcement highlights growing tensions in the region and the strategic significance of the waterway.
Tangsiri posted on X that two ships that disregarded Iranian warnings were specifically targeted in the Strait. He criticized the United States’ promises to protect vessels as “hollow” and suggested crews relying on these assurances had put themselves at risk. He identified the ships as Express Rome and Mayuree Naree, noting they attempted to cross without authorization.
The Strait of Hormuz remains a vital artery for global oil transport, historically handling nearly one-fifth of the world’s crude supply. Iran has increasingly restricted vessel passage amid ongoing U.S.-Israeli military operations against the country. Authorities stress that ships not serving U.S. or Israeli interests can still transit safely, provided they comply with Iran’s requirements.
Global markets have already reacted to these restrictions. Energy and commodity prices have surged, with analysts warning that prolonged tensions could trigger record-high costs worldwide. Washington’s failure to provide the promised naval escorts has amplified market uncertainty and disrupted shipping plans.
Despite the heightened risks, Iran has reportedly increased its oil exports. Data from maritime tracking shows Iranian tankers moving an average of 2.1 million barrels per day, surpassing February’s exports. Seven tankers have successfully loaded oil since hostilities began, with at least two now safely navigating the Persian Gulf.
Experts note that Iran’s ability to maintain shipments contrasts with declining outputs from other regional producers. This demonstrates Tehran’s strategic advantage in controlling the Strait of Hormuz. Analysts suggest that the enforcement of stricter passage rules could further shift energy dynamics and influence global geopolitics. Officials emphasize that any vessel must adhere to Iran’s directives to ensure safe transit. The policy reinforces Tehran’s authority over one of the most critical maritime chokepoints.
For international operators, compliance will be essential to avoid potential confrontations. The situation remains fluid, with regional security and energy markets closely monitoring developments. Iran’s measures may set new precedents for naval control, while global stakeholders assess the economic and political consequences. Future adjustments to the passage rules could further impact trade flows and diplomatic relations in the Gulf.
