The US Treasury has blacklisted two Iranian firms that sold ships a strange kind of "insurance" for passing through the Strait of Hormuz — and took payment in bitcoin. Persian Gulf Marine Insurance Company and a platform called HormuzSafe ran a simple racket: skip the policy, and Iranian forces might seize your vessel. Buy it, and you sail through untouched.
The catch is that Iran itself created the danger it was charging ships to avoid. Treasury didn't call this insurance — it called it extortion. HormuzSafe was built by Iran's Ministry of Economy, and the money flowed through the Persian Gulf Strait Authority, an IRGC-linked body Washington had already sanctioned back in May, straight into the Revolutionary Guard's coffers.
Accepting crypto wasn't incidental. A dollar wire transfer runs through correspondent banks that would flag and freeze it almost instantly. Bitcoin skips SWIFT and the traditional banking rails entirely, making the money harder to intercept in real time — though not impossible to trace after the fact, which is exactly how investigators reconstructed the scheme from the public blockchain.
The same action hit eight shipping companies registered in China, Hong Kong and the Marshall Islands, plus eight tankers used to move Iranian crude. Treasury Secretary Scott Bessent said the US "will not allow Iran to hold global commerce hostage" to fund IRGC terrorism and repression. Iranian state media had earlier floated a $10 billion revenue target for the scheme, a figure Treasury didn't validate and that looks wildly optimistic next to its actual scale.
For crypto markets, it's another reminder that bitcoin's use as a sanctions workaround now draws serious regulatory attention — and that a public ledger can end up working against the people trying to hide behind it.
