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.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Russia's 2022-2023 yuan-routing transition for crude sales after SWIFT exclusion followed the same architecture: Chinese correspondent banks processed ruble-yuan settlements outside the dollar system, and OFAC's enforcement against individual tankers was effective only where it could identify a US-nexus transaction in the chain.

The Kremlin's energy ministry publicly described this as an 'OFAC-proof' payment rail as early as October 2022. Iran has now extended the same template from commodity sales to maritime access fees, moving it from a trade-finance workaround into a toll-collection mechanism.

Counter-parallel: In 1973, Arab oil producers used the dollar-denominated oil trade as leverage by embargoing dollar-priced sales. The structural irony of the 2026 PGSA toll is the reverse: Iran is collecting a maritime access fee that specifically avoids the dollar to neutralise the currency's enforcement utility. The 1973 embargo weaponised oil's dollar dependency; the 2026 PGSA toll weaponises dollar exclusion.

The PGSA's up-to-$2 million per vessel toll generates direct revenue for Iran's IRGC financial conglomerate, settled outside dollar-clearing where OFAC has no automatic enforcement mechanism. The more consequential effect is the precedent: a yuan-denominated maritime access fee at any chokepoint controlled by a sanctioned sovereign replicates the architecture with minimal legal risk.

For shipping operators, the toll adds a cost layer on top of the already-elevated war-risk insurance premiums that Lloyd's P&I clubs extended after the 4 May UKMTO critical-tier advisory. A vessel paying both war-risk premiums and the PGSA toll faces combined per-transit costs that may exceed cargo value for lower-margin bulk carriers.

Consensus view: RUSI's financial-crime unit assesses the yuan-routing architecture as a direct extension of the post-2022 Russian crude evasion template. OFAC's Iran sanctions enforcement depends on the dollar-clearing leg: when a SWIFT message routes through a US correspondent bank, the bank has a legal obligation to screen and block.

A yuan payment through Chinese correspondent banks has no US nexus, no SWIFT leg requiring US-bank clearance, and no automatic OFAC tripwire. RUSI estimates enforcement against a yuan transaction requires OFAC to individually designate the vessel or operator, a process that takes weeks rather than milliseconds.

Counter-view: The Paulson Institute's finance analysts argue the yuan-routing precedent is less durable than it appears because Chinese state banks remain exposed to secondary sanctions via their US dollar correspondent relationships for non-Iran business.

ICBC, Agricultural Bank of China, and China Construction Bank each clear billions in dollar transactions daily through New York; OFAC has the authority to threaten dollar-clearing access as leverage against yuan-based Iran toll payments, even if it cannot block the yuan transaction itself.

Key tension: Whether OFAC's secondary-sanctions leverage over Chinese bank dollar-clearing is a credible threat given the Trump-Xi summit in six days, or whether the summit makes secondary sanctions politically undeliverable for the immediate window.

This Event

Hormuz tolls paid in yuan, $2m a ship

The yuan denomination defeats the SWIFT-and-correspondent-bank tripwire that makes OFAC's Iran sanctions automatically enforceable, turning the Hormuz toll into a working precedent for sanctions evasion.

Different Perspectives

EU Council / European Commission

With Orban's veto lifted and Magyar's Tisza government not placing a replacement block, the European Commission is signalling the first 90 billion euro Ukraine loan tranche for late May or early June 2026. Disbursement depends on Magyar's 5 May government formation proceeding to schedule.

Germany

Russia's Druzhba northern branch transit halt from 1 May removes one of Germany's residual non-Russian crude supply options. The timing compounds Berlin's exposure in the same week Ukrainian strikes drive Russian refinery throughput to its lowest since December 2009.

IAEA / Rafael Grossi

Grossi confirmed the Zaporizhzhia Nuclear Power Plant lost external power for its 14th and 15th times within a single week in late April, with the Ferosplavna-1 backup feeder damaged 1.8 km from the switchyard. He was negotiating a further local ceasefire; the previous IAEA-brokered repair lasted less than a week.

Japan

Japan authorised direct PAC-3 exports to the United States on 30 April, breaking its post-1945 arms export restrictions to replenish Iran-war-depleted US stockpiles. The White House global Patriot export freeze remains in place; Japan's historic policy shift benefits US readiness without reaching Ukraine.

Kazakhstan

Russia's Druzhba northern branch transit halt from 1 May cuts Kazakhstan's access to the German crude market. Astana routes most of its export crude through Russian infrastructure, meaning Moscow's unilateral decision directly constrains Kazakh export diversification despite Kazakhstan's stated neutrality on the war.

Péter Magyar / Tisza Party / Hungary

Magyar targets 5 May for government formation ahead of the 12 May constitutional deadline. Orbán lifted the EU loan veto before leaving office; Magyar supports Hungary's opt-out but has not placed a new veto, leaving the first 90 billion euro tranche on track for late May disbursement.
