Majlis approves Hormuz toll bill

2 min read

A key Majlis committee approved the Hormuz toll bill, advancing legislation that would permanently ban US and Israeli vessels and require fees in Iranian rial from all other shipping. Once codified, the toll becomes reversible only through domestic political process ; no future ceasefire can unwind it.

Key takeaway

Committee approval advances legislation that would make Hormuz's contested status a matter of Iranian domestic law, not merely military posture.

The Majlis committee approved the Hormuz toll legislation on 1 April, advancing a bill that permanently bans US and Israeli vessels from the strait and requires fees in Iranian rial from all other shipping. The bill had been drafted in parliament on Day 25, moved to committee stage on Day 32, and has now cleared committee. Full parliamentary vote, Guardian Council review, and presidential signature remain.

There is a fundamental difference between the IRGC imposing a toll because it controls a strait and the Iranian Parliament enacting a law that makes the toll a statutory requirement. The first is a military fact reversible by military defeat. The second is a legal instrument reversible only by domestic political process. Iran had already demanded Hormuz sovereignty as a formal peace condition ; the legislation converts that negotiating demand into permanent law.

The bill bans US and Israeli vessels explicitly and requires fees in Iranian rial, forcing buyers to transact in a sanctioned currency. The NPT withdrawal bill is advancing on the same legislative track . Both bills are designed to survive any ceasefire: a ceasefire can stop the shooting, but it cannot repeal domestic Iranian legislation.

The IRGC's toll system had already been operating since around Day 12, with Chinese state ships paying and crossing . Codifying the practice into permanent law removes any ambiguity about whether a future Iranian government could unilaterally rescind it. If Trump withdraws in two to three weeks without securing this bill's reversal, the US leaves behind a legal architecture that makes Hormuz permanently contested.

Deep Analysis

In plain English

The Iranian parliament is voting on a law that would permanently charge ships money to use the Strait of Hormuz ; a narrow channel through which about one in five barrels of the world's oil passes. Right now, Iran is blocking the strait militarily during the war. This law would make that blockade permanent and legal under Iranian law, even after the war ends. American and Israeli ships would be banned outright. This matters because there is a big difference between Iran blocking the strait with soldiers, which can be reversed, and Iran blocking it with a law, which can only be reversed by Iran itself choosing to change the law.

Deep Analysis
Root Causes

The toll bill was drafted as a direct response to US and Israeli strikes on Iranian infrastructure . It converts an emergency military response into a permanent economic instrument, institutionalising the leverage Iran discovered it holds over global energy markets.

What could happen next?
  • Precedent

    First instance of a state attempting to codify transit fees for an international strait into domestic law, potentially triggering a global UNCLOS legal challenge.

    Long term · Assessed
  • Consequence

    A ceasefire that leaves the Hormuz toll law in place fails to address the economic cause of the oil price spike.

    Medium term · Assessed
  • Risk

    Guardian Council and presidential signature stages create multiple veto points, but each ratification stage makes repeal politically harder.

Different Perspectives
India (BRICS meeting host, grey-market beneficiary)
India (BRICS meeting host, grey-market beneficiary)
New Delhi hosted the BRICS foreign ministers' meeting on 14 May that Araghchi attended under the Minab168 designation, giving India a front-row seat to Iran's diplomatic positioning. India's state refiners have been absorbing discounted Iranian crude through grey-market routing since April; Brent at $109.30 means every barrel sourced outside the formal market generates a structural saving.

Hengaw / Kurdish human rights monitors
Hengaw's daily reports from Iran's Kurdish provinces remain the sole independent cross-check on Iran's judicial activity during the conflict. Two executions across Qom and Karaj Central prisons on 15 May and five Kurdish detentions on 15-16 May indicate the wartime judicial pipeline is operating independently of military tempo.
Pakistan (mediator and bilateral partner)
Pakistan (mediator and bilateral partner)
Islamabad spent its diplomatic capital as the US-Iran MOU carrier to secure LNG passage for two Qatari vessels through a bilateral Pakistan-Iran agreement, spending its mediation credit for direct economic gain. China's public endorsement of Pakistan's mediatory role on 13 May is the structural reward.
China and BRICS bloc
China and BRICS bloc
Beijing endorsed Pakistan's mediatory role on 13 May, one day after the BRICS foreign ministers' meeting in New Delhi. Chinese state banks are processing PGSA yuan toll payments; China has not commented on its vessels' continued Hormuz passage, but benefits structurally from a non-dollar toll system it did not design.
Iraq (bilateral passage partner)
Iraq (bilateral passage partner)
Baghdad negotiated a 2-million-barrel VLCC transit without paying PGSA yuan tolls, offering political alignment in lieu of cash. Iraq's position inside Iran's adjacent bloc makes it the natural first bilateral partner and a template for how Tehran structures passage deals with states that cannot afford Western coalition membership.
Bahrain and Qatar (Gulf signatories)
Bahrain and Qatar (Gulf signatories)
Both signed the Western coalition paper while hosting US Fifth Fleet and CENTCOM's Al Udeid base, respectively. Qatar occupies the sharpest contradiction: it is on coalition paper while simultaneously receiving LNG passage through the bilateral Iran-Pakistan track, a position Doha has tacitly accepted from both sides.
