Strait of Hormuz Transit Fee: The Iran-Oman Toll Proposal Explained
Last updated: 1 July 2026
Iran has spent months asserting a right to authorise traffic through the Strait of Hormuz, and reporting now points to Iran and Oman moving to levy fees or otherwise tighten control over vessels transiting the world's most important oil chokepoint. This page explains what is actually being proposed, whether it is lawful, who would pay, and where things stand right now.
What is being proposed
There is no published tariff and no fee is currently being collected. What exists is a political signal: Iran wants to be recognised as the gatekeeper of Hormuz and has raised the prospect of charging for, or conditioning, passage. Independent tracking (Kpler) has recorded on the order of three dozen ships a day still crossing the strait, so traffic continues even as the diplomatic and security picture stays tense. Oman, which controls the southern side of the shipping lanes, is widely seen as the decisive variable in whether any scheme could function.
Why it matters
Roughly one-fifth of the world's seaborne oil and a large share of LNG move through Hormuz. Even the credible threat of a new cost or a tightening of control tends to move war-risk insurance premiums and freight rates before it moves anything else. For owners, charterers, P&I clubs and war-risk underwriters, the question is not only "is the strait open?" but "what does one transit now cost to insure and to price?"
The legal question: transit passage
Under the UN Convention on the Law of the Sea, ships have a right of transit passage through straits used for international navigation, and coastal states may not impede or charge vessels merely for exercising it. A unilateral transit toll would therefore draw strong legal objection from flag states and shipping bodies. The practical caveat is that enforcement on the water - inspections, warnings, re-routings - can diverge from the strict legal position, which is why the market prices risk rather than waiting for a legal ruling.
Who pays, and how the cost flows
If a fee or a control regime raised the cost of a Hormuz voyage, owners would typically seek to pass it to charterers, while war-risk premiums - quoted as a percentage of hull value per seven-day entry - would absorb much of the near-term shock. You can model that insurance side directly with our War-Risk Premium Estimator, which turns the live Hormuz risk band into an indicative additional premium for a given hull value.

Frequently asked questions
Is there currently a fee to transit the Strait of Hormuz?
No. As of the last update, no transit fee is being collected. Iran and Oman have signalled intent to assert greater control over Hormuz traffic and have floated the idea of charging vessels, but no tariff has been formally set or enforced.
How much would a Hormuz transit fee cost?
No official rate has been published. Any figure circulating is speculative. The commercial impact for owners and charterers would depend on the fee structure (per transit, per tonne, or per cargo value) and whether war-risk insurers treat the levy as an additional voyage cost.
Is charging for Strait of Hormuz transit legal?
It is disputed. Under the UN Convention on the Law of the Sea, ships enjoy the right of transit passage through international straits used for navigation, which coastal states cannot impede or charge for simply to pass. A unilateral transit toll would face strong legal objection, though enforcement realities on the water can differ from the legal position.
Who would collect a Hormuz transit fee?
The strait's navigable channels run through Iranian and Omani territorial waters. Any collection mechanism would involve one or both states. Oman controls the southern side of the shipping lanes, which is why analysts note Oman's cooperation is pivotal to any workable scheme.
How would a transit fee affect oil prices and shipping costs?
Roughly a fifth of the world's seaborne oil and LNG passes through Hormuz. A new cost or any tightening of control tends to widen war-risk insurance premiums and freight rates first; sustained disruption can feed into crude benchmarks. Owners typically seek to pass such costs to charterers.
