Iran’s decision to impose tolls on vessels transiting the Strait of Hormuz has raised concerns within the international maritime community, with the International Maritime Organization (IMO) warning of the potential risks and implications of such a move. The Strait of Hormuz, a critical chokepoint for global energy supplies through which nearly 20% of the world’s oil and natural gas exports pass, has been a focal point amid ongoing tensions between Tehran and other international actors.

The toll charges, reportedly introduced by Iran as part of conditions linked to a recent ceasefire agreement, represent a departure from established international maritime norms. Arsenio Dominguez, the IMO secretary-general, described the initiative as a “dangerous precedent” during a recent interview, emphasizing concerns about the lack of alignment with customary international practice and the uncertainty surrounding the safety assurances for vessels navigating the waterway under the new regime.

Ship movements through the Strait remain heavily restricted, with maritime traffic largely halted following the outbreak of hostilities. On Wednesday, only a small number of vessels, all with prior connections to Iran, were observed leaving the Arabian Gulf. Meanwhile, a few Chinese ships were noted waiting to transit, underscoring the fragile nature of the ceasefire and the ongoing disruptions to commercial shipping.

Dominguez indicated that efforts were underway to restore previously established systems that facilitated safer navigation through the strait, notably the international traffic separation scheme that had been in place before the conflict. Additionally, a coalition of countries, including the United Kingdom, is collaborating to verify the absence of naval mines in the region—no confirmed mines have been detected to date, but the verification process aims to reassure shipping safety.

The situation remains dynamic against a backdrop of conflicting statements from U.S. officials, including President Donald Trump, who alluded to potential joint U.S.-Iran toll collection arrangements in the future. However, concrete details on implementing such proposals have yet to materialize, and maritime activity in the strait has not seen significant improvement.

As tensions persist, the international maritime community continues to monitor developments closely, emphasizing the importance of maintaining free and secure passage through one of the world’s most strategically significant maritime corridors.
