Iran has established what amounts to a formalized toll system at the Strait of Hormuz, accepting Chinese yuan and crypto – specifically stablecoins pegged to fiat currencies – as payment for naval escort through the waterway, according to a Bloomberg report published April 1.
The system, administered through an Islamic Revolutionary Guard Corps-linked intermediary, assigns each nation a friendliness ranking of one to five and requires vessel operators to submit documentation for geopolitical vetting before receiving a VHF-broadcast passcode and IRGC Navy escort. At least two vessels have already paid in yuan, with oil tanker fees reportedly opening at $1 per barrel.
A draft proposal to let Iran collect transit fees in the Strait of Hormuz has been prepared and would be sent to parliament’s research center next week for legal review, an Iranian lawmaker said on Thursday.
Mohammadreza Rezaei Kouchi said he had prepared the draft jointly with…

We suspect this represents something structurally distinct from the informal blockade enforcement that characterized Iran’s earlier Hormuz posture: the parliamentary approval of a transit fee bill – reported by semi-official Fars news agency, citing lawmaker Mohammadreza Rezaei Kouchi, who stated that “we provide its security, and it is natural that ships and oil tankers should pay such fees” – suggests Iran is institutionalizing crypto and yuan settlement as a durable mechanism for extracting revenue from a sanctions-constrained chokepoint, not improvising under battlefield pressure.

Hormuz And Iran Crypto Tolls: How the Payment Mechanism Reportedly Works
According to the Bloomberg report, ship operators seeking Hormuz transit clearance must submit vessel ownership records, flag registration, cargo manifests, destination ports, crew lists, and AIS tracking data to an IRGC-linked intermediary.
The IRGC Navy’s Hormozgan Provincial Command then conducts sanctions screening and geopolitical vetting, checking for ownership or cargo ties to the United States, Israel, or nations classified as adversaries under Iran’s ranking system. Clearance, when granted, arrives in the form of a passcode broadcast over VHF radio, followed by a naval escort through the strait.
The currency structure is deliberate. Yuan settles outside the SWIFT-dependent dollar clearing system entirely, while stablecoins – if denominated in USDT or USDC – technically reference dollar value but transfer on blockchain rails that bypass correspondent banking.
Bloomberg reported that at least two vessels have completed yuan-denominated payments, with oil tankers the prioritized cargo class. The $1-per-barrel opening rate for oil tanker negotiations implies that a single Very Large Crude Carrier carrying 2 million barrels could generate a $2 million toll – a figure that scales rapidly across the roughly 20% of globally traded oil and gas that normally transits the strait.
We suspect the stablecoin preference, rather than Bitcoin or Ethereum, is operationally rational: stablecoins eliminate price volatility between invoice and settlement, making them functionally equivalent to dollar wire transfers for the receiving party while remaining nominally outside the dollar clearing system.
This is precisely the architecture that OFAC has been attempting to close through pressure on stablecoin issuers – and precisely why the Hormuz toll mechanism, if it scales, creates direct enforcement pressure on Tether and Circle.
