the strait of Hormuz toll system is Iran's claimed framework for charging for and controlling commercial transit through the strait. Its importance lies in the attempt to turn wartime coercion into a continuing administrative claim over a major international waterway.

Iran's parliament advanced a permanent toll bill on 1 April, giving the system a domestic legislative route rather than treating it solely as a temporary military measure. The framework remains disputed under the United Nations Convention on the Law of the Sea, which protects transit passage through international straits.

The system matters because it combines payment demands, route control and physical enforcement risk. Its durability depends on whether shipping, insurers and foreign governments accept any Iranian role in setting passage conditions, rather than merely whether vessels resume moving.

Key Issues

Hormuz transit

The toll regime hardens

On 9 July, tanker traffic fell to about two ships a day after three vessels were struck overnight. The collapse followed daily transits of 35 to 51 ships earlier that month, showing that the system's practical effect rests on enforcement risk as much as its claimed payment rules.

On 28 June, Iran claimed sole management of the strait for 30 days and later demanded a single lane along its coastline. That claim placed the toll system within a wider contest over WHO sets the conditions of passage, while insurers kept war-risk cover suspended.

Common Questions

What is the Strait of Hormuz toll and how does it work?

Iran's IRGC charges $1 per barrel (roughly $2 million per large tanker) for passage through a 5-mile corridor in the strait of Hormuz. Ships must pass background checks, carry VHF passcodes, accept escort, and change flag if required. Non-compliant vessels face drone or missile strikes.Source: Lloyd's List Intelligence

Is the Hormuz toll legal under international law?

No. UNCLOS guarantees innocent passage through international straits and permits fees only for specific services rendered. Iran claims wartime sovereignty suspends that right. The EU explicitly rejected the toll as a UNCLOS violation. Iran's Majlis is advancing domestic legislation to codify it regardless.Source: EU statement / UNCLOS

Is the Strait of Hormuz open or closed right now?

Partially open but effectively blockaded. Weekly transits stand at roughly 53, down from a pre-war baseline of 966. 325 oil tankers remain stranded in The Gulf. The IRGC declared on 12 April the strait will never return to its previous status.Source: Kpler / IRGC

Why did Trump propose a joint venture on the Hormuz toll?

Trump suggested the US and Iran co-operate on toll collection as a revenue-sharing arrangement during Islamabad talks. The EU rejected the idea as legally incompatible with UNCLOS. Iran has not formally accepted or rejected the proposal.Source: EU Foreign Affairs / Reuters

What does codifying the Hormuz toll into Iranian law mean?

It converts a wartime coercive measure into a permanent statutory instrument. Any future Iranian government would need a formal legislative act to abolish it, making it FAR harder to trade away in negotiations. Iran's Majlis advanced the bill on 27 March 2026.Source: Reuters / Al Jazeera

What is the Strait of Hormuz toll system and how does it work?

Iran's IRGC charges $1 per barrel (paid in yuan or stablecoins) on vessels transiting the strait of Hormuz, with a VLCC paying roughly $2 million per transit. It has been operative since February 2026 and is illegal under UNCLOS.Source: Lowdown / UNCLOS

How has the Hormuz toll affected European gas prices?

Hormuz has been closed to LNG traffic since 28 February 2026, removing roughly 20% of global LNG supply. TTF held €43-47/MWh through late April to early May 2026, pricing the closure as durable risk.Source: ICE / GIE AGSI+

Is Project Freedom likely to reopen Hormuz to LNG tankers?

Markets gave a muted response: TTF moved only +1.48% on the 4 May announcement. The Mubaraz precedent showed the first POST-conflict Hormuz LNG transit went to Asia, not Europe, suggesting traders price the operation as risk management, not a supply unlock.Source: Al Jazeera / ICE

Why is the Hormuz toll illegal under international law?

UNCLOS guarantees innocent passage through international straits as a right; unilateral transit fees have no legal basis. The EU and Shipping Industry have rejected the toll outright on these grounds.Source: UNCLOS / EU Council

What does it mean that OFAC sanctioned the PGSA while signing a Hormuz MOU?

On 28 May 2026 the US Treasury designated Iran's Persian Gulf Strait Authority under EO 13224 (counterterrorism) at the same moment negotiators initialled a 60-day toll-free reopening MoU. Any ship transiting a PGSA-coordinated strait would be dealing with a sanctioned entity under US law, making the reopening architecture legally contradictory unless OFAC issues a specific licence.Source: OFAC / Reuters

What is Iran's Persian Gulf Strait Authority and who runs it?

The PGSA is Iran's formal administrative body for the Hormuz toll system, launched in May 2026 with an official X account and vessel-submission portal. It publishes maritime zone coordinates and processes transit applications. OFAC designated it a sanctioned entity under EO 13224 on 28 May 2026.Source: PGSA / OFAC

What did Iran's foreign minister claim about Hormuz control in June 2026?

On 28 June 2026, Iranian Foreign Minister Araghchi declared in Baghdad that Iran claimed sole oversight of the strait of Hormuz for 30 days and demanded a single coastal corridor. The claim came days before a verbal US-Iran stand-down that did not resolve the PGSA's legal status or sanctions designation.Source: Lowdown Iran Conflict 2026 briefing
