Majlis approves Hormuz toll bill

2 min read
13:55UTC

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
Lloyd's of London
Lloyd's of London
The Joint War Committee left Hormuz war-risk premiums at $10-14 million per voyage on 25 May, declining to move on Brent's 5% fall. The JWC's protocol requires a UN Security Council resolution or bilateral government certification letter before de-listing, and neither has arrived: a verbal understanding does not satisfy the formal condition the reinsurance market's treaty terms require.
Gulf Arab producers
Gulf Arab producers
Saudi Arabia and UAE depend on Hormuz for their own crude exports; Aramco CEO Nasser has warned no oil market recovery arrives until 2027 if the blockade continues past mid-June. Monday's $98.96 Brent settlement shortens nothing for Gulf producers without a signed instrument and a Pentagon mine-clearance timeline that runs up to six months post-ceasefire.
Qatar
Qatar
Qatar holds $12bn of frozen Iranian assets at the centre of the sequencing dispute but cannot release them without explicit US Treasury authorisation, given the original freeze was a US instrument. As the asset-holding state, Qatar's leverage is real but passive: it is the escrow holder, not the decision-maker, and any resolution requires US Treasury sign-off that Trump has withheld.
Pakistan
Pakistan
With both Prime Minister Sharif and army chief Munir simultaneously in Beijing on 25 May, Pakistan has for the first time consolidated its civilian and military mediation tracks under China's roof. Munir's direct Tehran-to-Beijing flight signals that the security and financial threads of the sequencing problem are now being worked in parallel rather than sequentially.
China
China
Beijing hosted Pakistan's principal mediators and Iran's China envoy Ghalibaf simultaneously on 25 May while its banking regulator capped new state-bank lending to five sanctioned refiners. China is simultaneously the most credible third-party underwriter of the $12bn sequencing and the state whose institutions face live OFAC secondary-sanctions exposure if the deadlock persists through GL V's expiry.
United States
United States
Trump posted on 24 May that the blockade holds until a deal is certified and signed, ruling out the informal MOU structure both sides had been building. The 'certified, and signed' condition is the first operational bar Trump has attached in 87 days, but it arrived without an executive instrument, maintaining the gap between posted ultimatum and signed US policy.
