Tehran is attempting to leverage one of the world’s most critical maritime chokepoints as a bargaining chip in a high-stakes diplomatic gamble. As part of its proposals to end the current conflict with Israel and the United States, Iran is seeking the authority to impose transit fees on ships traversing the Strait of Hormuz, effectively proposing to turn the waterway into a toll route.
The move comes after weeks of restricted traffic in the strait, where the Islamic Revolutionary Guards Corps (IRGC) has blocked most vessels and reported firing on ships in the Gulf. The proposal represents a significant departure from established maritime norms and could fundamentally alter the economics of global energy transport if realized in a permanent peace deal.
The Strait of Hormuz is a narrow strip of water, only 34 km (21 miles) wide, separating Iran and Oman. It serves as the primary artery connecting the Persian Gulf to the Indian Ocean, facilitating the passage of approximately one-fifth of the world’s total oil supplies, as well as essential shipments of fertilizers and other vital goods.
The Mechanics of Tehran’s Proposal
According to a senior Iranian official, the demand for transit fees is intended to be a core component of any permanent peace settlement following the escalation that began with U.S. And Israeli strikes on Iranian leadership on February 28. The proposed fee structure would not be flat; instead, it would vary based on the type of vessel, the nature of its cargo, and other unspecified prevailing conditions.
In a parallel effort to formalize this control, Iran’s deputy foreign minister, Kazem Gharibabdi, recently stated that Tehran is drafting a protocol with Oman. This agreement would require ships to obtain specific permits and licenses to pass through the strait. While Gharibabdi characterized these measures as a means to facilitate transit rather than restrict it, the requirement for state-issued permits suggests a move toward a regulated, rather than free, maritime corridor.
Oman has acknowledged holding discussions with Iran regarding options to ensure smooth transit, though the Sultanate has not confirmed whether any formal agreements have been reached. Meanwhile, reports have surfaced regarding a potential $2 million payment made by a single vessel to secure passage through the blocked strait, though these reports remain unconfirmed.
Global Opposition and Legal Hurdles
The international community has reacted with sharp opposition to the idea of a paid transit system in the strait. Shipping industry officials have noted that a unilateral move to demand fees for traversing a natural strait is unprecedented in modern history. The U.S. Administration has been explicit in its stance; President Donald Trump stated on Monday that the free flow of oil through the strait must be a non-negotiable element of any peace deal.
Regional stakeholders, particularly Gulf states whose economies rely on the export of hydrocarbons, view the proposal as an existential threat to their trade. The United Arab Emirates stated over the weekend that the waterway “cannot be held hostage by any country” and insisted that free navigation be guaranteed in any final settlement. Similarly, Qatar’s foreign ministry asserted that all regional countries possess the right to use the strait freely, suggesting that any financial mechanisms should only be discussed after the waterway is fully reopened.
From a legal perspective, Iran’s proposal clashes with the United Nations Convention on the Law of the Sea (UNCLOS). Under international maritime law, states bordering straits cannot demand payment simply for the permission to pass. While coastal states may charge for specific services—such as piloting, tugging, or port services—these cannot be used as a pretext for a general transit fee, nor can they be levied disproportionately against specific nations.
Comparing Global Maritime Transit Fees
| Waterway | Type | Fee Structure | Legal Basis |
|---|---|---|---|
| Suez Canal | Man-made Canal | Standardized Tolls | Sovereign Control (Egypt) |
| Panama Canal | Man-made Canal | Standardized Tolls | Sovereign Control (Panama) |
| Turkish Straits | Natural Strait | Service Charges Only | 1936 Montreux Convention |
| Strait of Hormuz | Natural Strait | Proposed Tolls | Proposed by Iran (Disputed) |
| Singapore Strait | Natural Strait | Free Passage | International Custom |
The Geopolitical Leverage Play
Despite the legal and diplomatic opposition, the international community faces a complex tactical dilemma. Forcing the reopening of the strait via military means would likely necessitate a prolonged ground operation along Iran’s mountainous coastline, where entrenched forces can target vessels from inland positions.
This puts significant pressure on China, which remains the largest importer of energy shipped through the strait and maintains strong diplomatic ties with Tehran. As a global power with a vested interest in both energy security and regional stability, Beijing may hold more influence over Tehran’s decision than Western powers.
The volatility of the region is further highlighted by other maritime chokepoints. While the Houthis in Yemen have periodically disrupted the Bab el-Mandeb Strait, alternative—albeit longer—routes exist. In contrast, the Strait of Hormuz offers no such detour for the vast majority of Gulf oil exports, making the prospect of it becoming a toll route a critical risk for global energy price stability.
The next critical phase will be the formalization of the peace proposals and whether the U.S. And Israel are willing to concede any level of maritime administrative control to Tehran in exchange for a cessation of hostilities. All eyes remain on the upcoming diplomatic rounds and the evolving protocol between Iran and Oman.
