Iran has increasingly consolidated its control over the Strait of Hormuz, a vital route for global oil transportation, by implementing a multi-layered system for maritime navigation. This system involves government-to-government agreements, inspections by the Islamic Revolutionary Guard Corps (IRGC), and potential fees for safe passage. For instance, the tanker Agios Fanourios I, carrying Iraqi crude oil to Vietnam, experienced a two-day ordeal due to IRGC inspections, which raised suspicions of smuggled cargo. While no payments were made for its transit, reports suggest that vessels could be charged upwards of $150,000 USD for safe passage, especially those not covered by diplomatic agreements. The U.S. Navy's blockade of Iranian vessels has further complicated navigation in the strait, which is crucial for about 20% of the world's oil supply. Iran's new control measures prioritize vessels linked to its allies, while imposing strict vetting procedures aimed at identifying connections to the U.S. or Israel. This evolving mechanism highlights the significant geopolitical tensions in the region, as countries navigate the complexities of maritime law and international sanctions.
