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.

Different Perspectives

Israel

The IDF struck a Lebanese army unit on 6 June, killing a colonel, and privately told Moscow that shelling near Bushehr was accidental, per Putin's SPIEF disclosure. Israel is advancing in Lebanon past an unenforced ceasefire text while maintaining a back-channel to Russia on nuclear-site deconfliction.

Lebanon

President Aoun told CNN on 5 June that Iran uses Lebanon as a bargaining chip and urged Hezbollah toward diplomacy; on 6 June an IDF strike killed a Lebanese army colonel on the Khardali-Nabatieh road. The Lebanese state is publicly rejecting Iranian tutelage while the army sustains casualties from Israeli fire and the Washington framework remains unenforced.

Bahrain

Bahrain's US Fifth Fleet headquarters was among the targets in the 5-6 June two-country salvo; its PAC-3 magazine stands at 87 per cent depletion with an 18-month resupply gap and no comparable arms sale has been announced. The state is defending a critical US regional command on a thinning interceptor stock.

Kuwait

Kuwait received a $1.98bn US counter-drone sale approval on the same day IRGC missiles targeted its bases; it expelled two Iranian diplomats on 4 June and filed a formal protest. The arms approval gives Kuwait a future capability but leaves a 6-18 month delivery gap that the salvo tempo is already pressing.

Russia

Putin reaffirmed Russia's offer to hold Iran's 440.9 kg HEU at SPIEF on 6 June, said Russia is not arming Iran, and disclosed that both the US and Israel privately told Moscow that shelling near Bushehr was accidental. The restatement casts Moscow as the only remaining mediator both sides call, a position serving Russian interests whatever the nuclear file produces.

Iran

The IRGC, per Iranian state media, fired seven ballistic missiles at US bases in Kuwait and Bahrain, the largest two-country salvo of the war, and framed the launches as lawful retaliation; Foreign Minister Araghchi rejected Aoun's bargaining-chip accusation and Velayati warned Beirut against diplomatic naivety. Tehran has sent no HEU counter-proposal since Araghchi confirmed no progress on 4 June.
