Hormuz tolls paid in yuan, $2m a ship

Lloyd's List confirmed vessels have paid up to $2 million per ship in Chinese yuan to obtain Persian Gulf Strait Authority transit clearance, the first confirmed payments routing outside the dollar correspondent-banking system OFAC's enforcement architecture relies on.

Key takeaway

A yuan toll booth at Hormuz collects revenue in a currency OFAC's screening architecture cannot automatically catch.

Lloyd's List confirmed on 7 May that vessels have paid up to $2 million per ship to obtain Persian Gulf Strait Authority (PGSA) transit clearance, with payments settled in Chinese yuan 1. Iran has not published a tariff schedule, and the PGSA registration channel that opened on 6 May still shows zero formal sign-ups from the 2,000-vessel stranded fleet. The toll route is operating in parallel without a public registry: vessels pay quietly, then transit.

The architecture matters more than the figure. OFAC, the US sanctions enforcement office, runs almost entirely on the dollar. A SWIFT message routed through a US correspondent bank trips a screening obligation under executive orders 13902 and 13224, the legal spine of the 1 May Sanctions Bulletin (SB0483) issued alongside General Licence W . The screening fires automatically; the bank has to act or face penalties. A yuan-denominated payment routes around all of it, with no SWIFT trail through New York, no US correspondent bank on the chain, and no automatic OFAC tripwire.

The legal foundation Iran is invoking is the Majlis Hormuz sovereignty law ratified on 2 May and the PGSA structure created on 5 May. Together they convert a maritime chokepoint into a domestic-law toll booth, and the yuan denomination is the architectural choice that lets Iran's PGSA collect outside the dollar system.

The template is a 2022 import. Russian crude buyers settled in yuan through Chinese correspondent banks after the 2022 SWIFT exclusions, exactly to escape the dollar-clearing leg that OFAC sanctions hook into. Iran has now extended that template from commodity sales to maritime access fees, the first known instance of a sanctioned state using yuan-denominated transit revenue at scale. SB0483 was a warning framing rather than a new prohibition; the vessels paying in yuan face secondary-sanctions risk under existing executive orders, but enforcement against a yuan transaction with no US nexus requires OFAC to designate the specific vessel or shipper rather than rely on the automatic correspondent-bank step. That is a measurably slower, more political enforcement path.

A signed MOU would unwind the PGSA collection inside a month. That ties the precedent's durability to the 9 May reply window: every day the toll collects in yuan is a day the dollar enforcement architecture falls one notch shorter, and a day the yuan-routing template hardens into a usable model for the next sanctioned state to copy.

Deep Analysis

In plain English

Ships passing through the Strait of Hormuz are being charged up to $2 million each to get through, paid in Chinese yuan rather than US dollars. That currency choice is deliberate: the US sanctions enforcement system works by monitoring dollar payments through American banks. Pay in yuan through Chinese banks, and that monitoring system cannot automatically catch it. Iran has essentially found a payment route that the US cannot block the way it normally would. A signed peace deal would end the toll system; until then, the toll keeps collecting.

Deep Analysis
Root Causes

OFAC's Iran sanctions architecture was designed for a dollar-centric global financial system in which every significant cross-border payment eventually routes through a US correspondent bank. The 2022 Russian SWIFT exclusion was the proof-of-concept that demonstrated dollar-clearing avoidance at scale.

The IRGC's finance operation observed the Russian crude routing model for three years before the 2026 conflict opened. Iran chose yuan to exploit the same structural gap: sanctions enforcement requires a US-nexus transaction in the payment chain, and a yuan toll settled through Chinese correspondent banks provides none.

What could happen next?
  • Precedent

    The yuan-denominated PGSA toll is the first confirmed instance of a sanctioned state using yuan-denominated transit revenue at scale; if it persists, it becomes the model for any future sanctioned chokepoint controller.

    Long term · 0.8
  • Risk

    OFAC's only available response, individually designating each vessel or operator, is measurably slower than the automatic correspondent-bank tripwire, creating a window in which the toll collects with near-impunity.

    Immediate · 0.85
  • Opportunity

    A signed MOU would unwind the PGSA collection within the 30-day Hormuz reopening timeline, extinguishing the yuan-routing precedent before it fully hardens into a copyable model.

Different Perspectives
IAEA
IAEA
Director General Rafael Grossi appeared in person at the UNSC on 19 May and warned that a direct hit on an operating reactor 'could result in very high release of radioactivity'. The session produced a condemnation record but no resolution, and the Barakah perimeter was already struck on 17 May.
Hengaw (Kurdish rights monitor)
Hengaw (Kurdish rights monitor)
Hengaw documented three judicial executions and the detention of Kurdish writer Majid Karimi in Tehran on 19 May, establishing Khorasan Razavi province as the newest geography in Iran's wartime judicial record. The organisation's Norway-based operation continues to surface a domestic repression track running in parallel with every diplomatic and military development.
India
India
Six India-flagged vessels conducted a coordinated cluster transit under PGSA bilateral assurances during the 17 May window, paying no yuan tolls. New Delhi's inclusion in Iran's state-to-state passage track insulates Indian energy supply without requiring endorsement of the PGSA's yuan-toll architecture or alignment with the US coalition.
Pakistan
Pakistan
Pakistan is the only functioning diplomatic bridge between Tehran and Washington. Its role is relay, not mediation in the settlement sense: it conveyed Iran's 10-point counter-MOU in early May, relayed the US rejection, and is now passing 'corrective points' in the third documented exchange of this sub-cycle without either side working from a shared text.

Twenty-six coalition members have published no rules of engagement eight days after the Bahrain joint statement; Lloyd's underwriters have conditioned war-risk reopening on written ROE from either Iran or the coalition. Italian and French mine-countermeasures deployments are operating on the in-water clearance task CENTCOM Admiral Brad Cooper's 90% mine-stockpile claim does not address.
Saudi Arabia
Saudi Arabia
Riyadh has not publicly commented on the Barakah strike or the 50-47 discharge vote. Saudi output feeds the IEA's $106 base case; the $5 Brent premium above that model reflects institutional uncertainty no Gulf producer can compress through supply adjustment alone.
