In a move that could reshape international maritime law, Iran is demanding the right to collect tolls from ships passing through the Strait of Hormuz as a condition to reopen the critical waterway. This strategic strait, through which 20% of the world’s oil flows, has been a focal point of conflict since Iran blocked it amid tensions with the U.S. and Israel.
Iran’s Toll Proposal Threatens Maritime Freedom
Iran’s demands, outlined in a 10-point proposal, would allow it and Oman to charge vessels for passage, a direct violation of the United Nations’ Convention on the Law of the Sea. This treaty, ratified by 172 countries but not Iran or the U.S., guarantees "innocent passage" to peaceful ships. Experts warn that granting Iran toll authority could set a dangerous precedent, potentially emboldening other nations to restrict vital trade routes like the Strait of Gibraltar or the Strait of Malacca.
"Freedom of navigation has always been recognized, including specifically in straits. The sea doesn’t belong to anyone," said Philippe Delebecque, maritime law expert at Paris’ Sorbonne University.
Economic and Geopolitical Implications
Iran’s tollbooth scheme, already partially implemented, has reportedly required ships to divert through Iranian territorial waters and provide cargo details to intermediaries linked to the Islamic Revolutionary Guards Corps. At least two vessels allegedly paid $2 million in Chinese yuan for passage. While Iran claims toll revenue would fund reconstruction, critics argue it would cement Tehran’s control over the strait and undermine global trade freedoms.
The U.S. has rejected Iran’s toll proposal, with analysts noting that Gulf oil producers also oppose the plan. Reopening the strait is crucial to easing global energy shortages that have spiked prices worldwide. However, granting Iran toll authority could embolden adversarial nations like China to restrict movement in contested waters, such as the Taiwan Strait, further destabilizing international trade norms.
The standoff underscores the delicate balance between ending conflict and preserving principles of global maritime law—a balance that, if disrupted, could reshape the rules of international commerce.
