Tehran is attempting to exert formal control over the Strait of Hormuz, a critical passage for global oil and gas, by proposing a charge for passage. This move contradicts established international shipping norms which prohibit countries from imposing fees for safe navigation through international waterways. Though experts are skeptical about its success, the proposal has nonetheless unsettled the shipping industry.

For nearly three months, shipping companies have faced increased uncertainty, as vessels and workers are stuck in the Persian Gulf amid ongoing conflict in Iran. There is concern that, emboldened by its geographic advantage, Iran might influence strait traffic even after hostilities subside. These threats have the potential to cause lasting harm to the global economy.

Arsenio Dominguez, head of the International Maritime Organization, criticized the idea of a toll system. He stated that such measures contradict the principles of freedom of navigation and innocent passage. Dominguez expressed these views following reports of discussions between Iran and Oman, a country bordering the strait and allied with the U.S., about implementing a fee system.

Mr. Dominguez emphasized that mandatory tolls disregard international maritime norms. His stance highlights the importance of maintaining free and open international shipping routes.
