Global Shipping Groups Urge UN To Reject Any Compulsory Transit Tolls In Strait Of Hormuz
Our take

The recent plea from global shipping groups to the United Nations to reject compulsory transit tolls in the Strait of Hormuz highlights a critical intersection of maritime commerce, geopolitical instability, and the potential for escalating tensions. The reported movement towards an agreement between Iran and Oman to manage the Strait, a vital chokepoint for approximately 30% of the world's seaborne oil trade, introduces a layer of complexity that demands careful scrutiny. This situation is inextricably linked to broader discussions around maritime security and resource governance, a theme we’ve explored previously in our analysis of [Regulating project-associated greenhouse gas emissions from deep-seabed mining: a climate-sensitive EIA framework for the International Seabed Authority], demonstrating how resource management and international agreements are inherently intertwined. Furthermore, the heightened tensions in the region, as evidenced by recent events such as the attack on an Indian-flagged ship – detailed in [Indian-Flagged Ship With 14 Crew Members Overturns & Sinks In Red Sea After Attack] – underscore the fragility of maritime routes and the potential for disruption. The shipping industry's concern over tolls reflects a deeper anxiety about the potential for arbitrary control and the imposition of unilateral measures that could significantly impact global trade flows.
The impetus behind Iran’s potential implementation of transit tolls remains unclear, although it’s widely understood to be linked to economic pressures and a desire to assert greater control over regional waterways. While Oman's involvement could potentially moderate Iran’s actions, the history of the Strait of Hormuz is marked by periods of heightened tension and intermittent disruptions. The threat of military action, as exemplified by statements like those referenced in [‘Will Sink You’, Tehran Warns U.S Navy If It Continues Naval Blockade Around Iranian Ports], further complicates the situation and adds to the uncertainty surrounding the future of maritime traffic. The shipping groups' call for the UN's intervention is strategic; it seeks to establish a framework that prevents unilateral actions and ensures the free flow of commerce through this critical waterway, aligning with established international maritime law and principles of freedom of navigation. The potential for Iran to unilaterally impose tolls, regardless of Oman's involvement, raises serious questions about the enforceability of such measures and the potential for retaliatory actions from other nations.
The broader significance of this development extends beyond the immediate impact on shipping costs and trade volumes. It underscores the vulnerability of global supply chains to geopolitical risks and the importance of maintaining stable maritime environments. The Strait of Hormuz is not simply a geographic feature; it's a strategic asset with profound implications for energy security and global economic stability. Any disruption to the flow of oil through this waterway can trigger significant price volatility and have far-reaching consequences for economies worldwide. The current situation calls for a nuanced and collaborative approach, prioritizing diplomatic solutions and adherence to international law. A unilateral imposition of tolls, without a clear and internationally recognized legal basis, risks escalating tensions and potentially triggering a wider conflict, which would have devastating consequences for the global economy and maritime security. The integrated data ecosystem we champion at World Data Ocean aims to provide the real-time, validated information needed to assess such risks and inform decision-making, underlining the importance of calibrated monitoring and predictive analysis.
Looking ahead, the key question will be whether Iran and Oman can reach a mutually acceptable agreement that addresses Iran’s economic concerns while safeguarding the principles of freedom of navigation. The UN’s role in mediating this process and establishing a clear legal framework will be crucial. A failure to do so could lead to a protracted standoff, characterized by heightened military presence in the region and an increased risk of maritime incidents. The longer-term implication is a potential shift towards diversifying energy supply routes and exploring alternative transportation modes, albeit at considerable cost and logistical complexity. The evolution of this situation warrants continuous, empirical observation and longitudinal data analysis to understand its true impact on global trade and maritime security.


Eight major shipping associations have called on the United Nations and the International Maritime Organization (IMO) to oppose any compulsory tolls or charges on vessels using the Strait of Hormuz, warning that such measures could affect global trade and energy supply chains.
The joint letter was sent on Monday to UN Secretary-General António Guterres and IMO Secretary-General Arsenio Dominguez. It was signed by the Asian Shipowners Association (ASA), BIMCO, Cruise Lines International Association (CLIA), European Shipowners (ECSA), International Chamber of Shipping (ICS), INTERCARGO, INTERTANKO and the World Shipping Council (WSC).
The organisations said introducing mandatory transit fees or service charges for ships passing through the Strait of Hormuz would be a major change from current international practice and could affect the legal framework governing navigation through international waterways.
“Introducing compulsory charges for transit, or service fees that are a toll in all but name, through the Strait of Hormuz would represent a significant departure from established international practice,” the groups said in the letter.
The appeal comes amid reports that Iran and Oman are moving towards an agreement to manage the Strait of Hormuz, a key route for global energy shipments.
The shipping groups said seafarers have continued working in difficult conditions since the beginning of the conflict, with some injured and others losing their lives while operating at sea. They said the safety of seafarers and freedom of navigation must remain protected.
The associations warned that allowing transit charges in the Strait of Hormuz could create a precedent for similar measures in other international waterways. They said this could increase uncertainty for shipping companies and global businesses that depend on predictable maritime routes.
The groups also said additional costs on maritime transport would eventually affect supply chains, potentially contributing to higher energy prices, inflation and economic uncertainty.
“Any additional costs imposed on maritime transport inevitably flow through international supply chains,” the associations said, adding that the impact could affect people and businesses worldwide.
They urged that internationally recognised navigation rights should not be affected by political discussions over regional security and conflict resolution.
The organisations said they would continue working with the IMO and the United Nations to protect existing international rules governing navigation through strategic waterways, including those recognised under the United Nations Convention on the Law of the Sea (UNCLOS).
IMO Secretary-General Arsenio Dominguez has previously said that countries do not have the right to impose tolls, payments or charges on international straits, warning that such measures could create a harmful precedent for global shipping.
The possibility of a permanent toll system has raised concerns about the impact on energy markets, particularly in Asia, which imports a large share of Gulf energy exports.
Deborah Elms, head of trade policy at the Hinrich Foundation in Singapore, said higher costs linked to disruptions in the Strait of Hormuz could affect diesel prices, fertiliser costs and plastics supply. She added that while some oil shipments could potentially be redirected through pipelines, natural gas shipments remain more difficult to replace.
Shipping activity in the region has faced continued disruption during the conflict. The IMO has confirmed 64 incidents and 17 deaths in the area since the conflict began.
According to the IMO and UN Human Rights Chief Volker Türk, at least 6,000 seafarers remained stranded in and around the Strait of Hormuz as of late July.
