UN Rejects Iran's Hormuz Sovereignty Claim, Escalating Tensions in Maritime Trade

The International Maritime Organization (IMO) Governing Council has stated that countries should reject Iran's efforts to impose sovereignty over the Strait of Hormuz and Tehran's unilateral decision to create a body to control traffic through the waterway. The council, reaching a non-binding decision on Friday, affirmed that member states should not recognize such Iranian endeavors. This development raises significant concerns regarding maritime security and international law in the strategic strait, a vital artery for global energy supply.

The IMO, the UN's London-based shipping agency, is responsible for regulating the safety and security of international shipping. Its 40-member Governing Council discussed the protection of vital shipping lanes during its session this week. Gulf countries, the United States, and Iran have been at odds over the future of the strait. Iran's recently established Persian Gulf Strait Authority had issued an advisory in June, stating that no vessel would be permitted to pass through the waterway without a valid passage permit.

This decision comes amid renewed hostilities between the U.S. and Iran this week, including U.S. military airstrikes prompted by attacks on ships that Washington attributed to Tehran. These attacks have reignited concerns about the recovery of global oil supplies and shipping, highlighting the fragility of an interim truce aimed at ending the more than four-month conflict between the U.S. and Iran. The IMO Council “strongly condemned” Iran's decision and called upon member states not to recognize Iran's claims of sovereignty or its assertions of jurisdiction over the maritime zones of third states that violate their sovereign rights.

The escalating situation has had tangible impacts on markets. Commercial shipping through the Strait of Hormuz has sharply declined following the renewed military exchanges. According to shipping data from Kpler, only six cargo ships transited the strait on Thursday, down from 21 vessels on Wednesday, indicating a significant slowdown in maritime traffic. Crude oil prices temporarily spiked amidst the tensions, recovering to around $77 per barrel. IMO Secretary-General Arsenio Dominguez urged shipowners and operators to avoid exposing seafarers to unnecessary risks by transiting the Strait of Hormuz while tensions remain elevated.

These events must be viewed within the broader context of regional and political tensions between the U.S. and Iran. The Strait of Hormuz is a critical chokepoint through which approximately one-fifth of the world's oil and a significant amount of liquefied natural gas passes. Any instability in the region has direct and far-reaching implications for global energy markets. Iran, which does not have a seat on the IMO Council, rejected what it called “selective, politically motivated and legally unfounded allegations.” Iranian officials stated that their measures are intended to uphold maritime safety and security, safeguard Iran's sovereignty, and ensure non-threatening navigation, asserting that they do not constitute a closure of the strait.

Market analysts anticipate that geopolitical risks in the region will remain high in the near term. As international pressure on Iran mounts, it remains uncertain whether Tehran will retract its claims of control over maritime activities. This situation will continue to pose a persistent risk factor for global supply chains and energy prices, standing out as a development that investors must closely monitor.
