Iran Mulls Transit Fees on Ships in Strait of Hormuz, Lawmaker Says — A Potential Shift in Global Shipping Dynamics

Iran is considering a controversial proposal to impose transit fees on vessels passing through the strategically vital Strait of Hormuz, a move that could reshape the economics of global maritime trade and underscore Tehran’s increasing leverage over the crucial waterway. The proposal, disclosed by a senior Iranian lawmaker, comes amid heightened regional tensions and disruption of shipping traffic in the strait.

The Strait of Hormuz a narrow maritime chokepoint linking the Persian Gulf with the Gulf of Oman and the Arabian Sea is one of the world’s most important shipping lanes. Normally, around one-fifth of global oil and liquefied natural gas (LNG) shipments transit through it, making its security and accessibility central to global energy markets.

Proposal Aims to Monetise Iran’s Strategic Control

According to the Iranian Students’ News Agency, the Iranian parliament is reviewing a draft bill that would require foreign countries whose vessels use the strait for shipping, energy transit and food supplies to pay tolls and taxes to Iran. Proponents of the measure argue it reflects Iran’s growing ability to exert control over the passage following disruptions tied to the ongoing conflict involving Tehran.

An adviser to Iran’s supreme leader has hinted at the broader intent behind such measures, stating that a “new regime for the Strait of Hormuz” could be implemented after the eventual end of the war, granting Tehran greater authority to impose maritime restrictions and financial obligations on states that have sanctioned it.

Shipping Through Hormuz Has Already Been Disrupted

The backdrop to this proposal is a dramatic reduction in maritime traffic through the strait amid escalating conflict between Iran on one side and the United States and Israel on the other. Recent data suggests that in the opening weeks of the crisis, shipping transits plunged sharply, with only a small fraction of typical annual traffic managing to navigate the waterway.

The disruption has contributed to spikes in global oil prices with Brent crude climbing above $100 per barrel and forced many carriers to delay or reroute vessels away from the Gulf. Countries and maritime organisations are increasingly alarmed by the effect on global supply chains, particularly for energy and bulk goods.

Controversy and Global Impact

International shipping firms, insurers and governments already grapple with rising risk premiums and war‑risk surcharges for voyages in the region. The introduction of formal transit fees could compound those costs, pushing up freight rates, impacting energy prices, and forcing consumers and countries to absorb higher transportation expenses at a time of already strained global supply chains.

Analysts warn that such a move if enacted could have profound implications for free navigation and maritime law. Under international law, straits used for international navigation are generally subject to the right of transit passage, which ensures freedom of navigation. However, Iran’s unique political posture and current wartime assertions over the strait complicate this framework.

Geopolitical Ripple Effects

The potential toll proposal arrives as diplomatic and security tensions escalate around the strait. The United States and its allies have repeatedly emphasised the need to ensure open sea lanes. Washington has urged partner navies to ensure safe commercial passage, though allied naval support remains fragmented.

Simultaneously, proposals from other nations to establish safe maritime corridors to assist tens of thousands of seafarers stranded by halted traffic indicate international concern over the ongoing disruption.

Tehran’s Strategic Calculus

Iran’s approach reflects a potentially new phase in its strategic use of influence over the strait. Beyond military posturing, Tehran appears to be seeking not just tactical leverage but also economic compensation for the heightened risks and political power it wields over one of the globe’s most important trade arteries. Such a shift could set a precedent for how critical sea lanes are managed amid geopolitical conflicts, raising questions about long‑term security, international navigation rights and economic stability.
