Iran's Persian Gulf Strait Authority launched an official X account and a vessel-submission portal on 18 May, converting the Majlis-backed Hormuz toll from political signalling into an administrative interface ships must engage with.

Key takeaway

Iran's Hormuz toll moved from a slogan to a working permit office on 18 May.

Iran's Persian Gulf Strait Authority launched an official X account and a live vessel-submission portal on 18 May 2026, demanding ownership details, insurance, crew manifests, cargo declarations and routing for a transit permit through the Strait of Hormuz. Euronews reported the launch the same day 1. The body is IRGC (Islamic Revolutionary Guard Corps)-backed and answers to the Majlis, Iran's parliament. PGSA replaces a parliamentary mechanism Azizi posted as legislative intent two days earlier with a working administrative interface that ships now have to engage with one way or another.

the strait of Hormuz is the 33-km chokepoint through which roughly a fifth of seaborne oil moves each day. Permit systems there are not a matter of fee schedules alone; they reset who counts as the gatekeeper. Euronews relayed a market-reported figure of up to $2 million per transit in yuan-denominated fees 2, though PGSA has not published an official tariff. The absence of a public price list means insurance underwriters and tanker owners are bidding into a system whose terms are still being written by the office collecting them.

For the 26-nation coalition that signed the Hormuz joint statement on 12 May , the PGSA portal is the first hard test of UNCLOS Article 38 transit-passage rights against a sovereign administrative system. UNCLOS (UN Convention on the Law of the Sea) Article 38 protects freedom of transit through international straits, but it presumes the strait state is not running a permit office. Once a vessel registers with PGSA, even under protest, the coalition's legal frame stops being an open-seas argument and becomes a treaty dispute over a working bureaucracy.

Deep Analysis

In plain English

Iran set up a new government body called the Persian Gulf Strait Authority (PGSA) to control who passes through the Strait of Hormuz, the narrow waterway through which about 20% of the world's oil moves. For weeks the PGSA existed on paper only. On 18 May, it went live online: shipping companies can now submit their vessel's details and pay a fee of up to $2 million per trip, in Chinese yuan, to get a transit permit. Ships that file the paperwork are implicitly accepting Iran's right to charge. Ships that refuse must decide whether to risk the consequences. Neither option removes the legal dilemma the PGSA has created.

Deep Analysis
Root Causes

The PGSA's X-account launch rests on three structural conditions that no ceasefire automatically removes.

First, Iran never ratified the 1982 UN Convention on the Law of the Sea (UNCLOS). The transit-passage right that coalition planners invoke under UNCLOS Article 38 simply has no standing in Iranian domestic law, which Tehran updated in 2024 to assert jurisdiction over 'hostile-linked vessels' in what it terms Persian Gulf rather than international waters.

Second, the yuan-denominated payment rail routes outside the US dollar correspondent-banking system, creating a financial infrastructure whose utility to China, Russia, and sanctioned states predates and survives any Iran-specific political settlement.

Third, the PGSA emerged from a Majlis legislative mandate rather than an executive decree, giving it institutional depth that a presidential ceasefire commitment cannot unilaterally revoke without a parliamentary counter-vote.

Escalation

The PGSA going operational marks a qualitative step beyond political posturing: Iran now has an administrative interface that generates compliance dilemmas for every vessel, rather than a legislative threat that ships could ignore. Escalation risk comes not from the fee itself but from the first enforcement action against a vessel that refuses to file.

What could happen next?
  • Consequence

    Shipping companies face an immediate compliance fork: file with PGSA and implicitly accept Iranian jurisdiction, or refuse and absorb unquantified transit risk.

  • Risk

    If even a handful of carriers pay the yuan toll, the payment rail becomes self-reinforcing and difficult to wind back in a ceasefire negotiation.

    Short term · 0.72
  • Precedent

    A functioning yuan-denominated strait-toll mechanism would represent the first major energy-chokepoint fee collected outside the US dollar system, with implications for renminbi internationalisation well beyond the Iran conflict.

Update #102 · Iran signs Hormuz toll; Trump posts a cancelled strike

Different Perspectives
Human rights monitors (Hengaw, Amnesty International, Iran HRM)
Human rights monitors (Hengaw, Amnesty International, Iran HRM)
Monitors documented a second death sentence for Zahra Tabari, 68, reported cemetery record deletions at Behesht-e Zahra, and a poll showing 81.5% of medical residents want to emigrate, against a background of 200+ confirmed executions since February. Iran's security courts operate at uninterrupted wartime tempo regardless of the diplomatic track.
Pakistan (mediator)
Pakistan (mediator)
Islamabad carried Trump's revised MOU demanding HEU destruction to Iranian negotiators, formally inheriting the role of sole active mediator after Oman's forced withdrawal. Pakistan lacks Oman's banking infrastructure for frozen-asset routing and carries its own regional stakes, making it a less structurally neutral broker.
Kuwait
Kuwait
Kuwait intercepted Iranian missiles and drones for a second time in days on 1 June, with air-raid sirens sounding nationwide, after invoking Article 51 self-defence on 28 May following the Ali Al Salem ballistic-missile strike. The repeated interceptions test whether Kuwait's domestic politics can sustain hosting US forces as a de facto co-belligerent.
China (PRC)
China (PRC)
Beijing sent scholars to Shangri-La rather than its defence minister and addressed Taiwan without mentioning Iran, maintaining bilateral energy corridor protection with Tehran while refusing diplomatic exposure at multilateral forums. Trump barred China as an HEU custodian on 27 May, removing Beijing from the deal architecture while China continues supplying DPI hardware that caps Iran's internet.

Lloyd's held its Hormuz war-risk designation at $10-14 million per voyage while Brent recovered to $93.91, maintaining the structural divergence from futures pricing that has persisted since late May. Underwriters require a UN Security Council resolution or government certification letter, not diplomatic optimism.

Five Gulf states wrote to the IMO on 21 May rejecting Iran's PGSA transit authority over international waters; Saudi Arabia and the UAE have not confirmed participation in the European Hormuz mission. The GCC is navigating between US security guarantees and exposure to Iranian fire, with no Gulf state formally co-belligerent except Kuwait.
