Iran Is Charging $2 Million Per Tanker to Cross the Strait of Hormuz. It Accepts USDT.
Iran's Revolutionary Guard has turned the Strait of Hormuz into a toll booth. Ships wanting safe passage through the world's most important oil chokepoint now pay fees denominated in Chinese yuan or cryptocurrency — with USDT and USDC as the preferred payment methods, according to Bloomberg.
The base rate: $1 per barrel. A Very Large Crude Carrier hauling 2 million barrels generates a $2 million toll. Roughly 20% of globally traded oil and gas transits this strait. Do the math on what full enforcement would mean.
How the System Works
An IRGC-linked intermediary administers the process. Ship operators submit ownership records, flag registration, cargo manifests, destination ports, crew lists, and AIS tracking data. Each nation gets a "friendliness ranking" from one to five. The IRGC's Hormozgan Provincial Command runs geopolitical vetting — checking for ownership or cargo ties to the United States and Israel. Clear the screening, and you get a VHF radio passcode and an Iranian naval escort through the strait.
Pakistan has already secured transit permits for 20 flagged vessels — 14 more than it needs, reportedly reselling the unused slots. At least two Chinese vessels have completed yuan-denominated payments. Some nations have negotiated no-fee transits entirely.
Why Stablecoins, Not Bitcoin
The choice of stablecoins over volatile crypto is deliberate. USDT and USDC eliminate price volatility between invoice and settlement. A $2 million toll stays $2 million whether it takes two hours or two days to process. For Iran, stablecoins function as dollar wire transfers while remaining nominally outside the dollar clearing system — no SWIFT, no correspondent banks, no OFAC chokepoint.
That last part is the uncomfortable irony. Dollar-pegged stablecoins — instruments designed to maintain a 1:1 peg with USD — are being used specifically to route around US financial sanctions. The very thing that makes USDT useful to Tether's legitimate customers is what makes it useful to the IRGC.
The Freezing Problem
Here's the question nobody in these Bloomberg reports is asking: can Tether and Circle freeze these wallets? Both companies have done it before. In January 2026, Circle and Tether simultaneously froze wallets belonging to Wallex, an Iranian exchange, at the request of the US government. If the IRGC's intermediary is receiving USDT to known wallets, those wallets are theoretically freezable.
But freezing toll payments for a naval chokepoint that controls 20% of global oil supply is a different calculation than freezing an exchange's wallets. The geopolitical blowback would be immediate. Iran's parliament has already passed legislation institutionalizing the transit fee system, suggesting they view crypto and yuan settlement as a durable mechanism — not a temporary workaround.
Traffic through the strait remains far below normal levels. Over 320 tankers and gas carriers are trapped in the Arabian Gulf, with roughly 2,000 other vessels backlogged. The toll system is being tested on a handful of daily transits, not full throughput. If and when traffic normalizes, the revenue implications — and the stablecoin flow volumes — scale dramatically.
