One Dollar Per Barrel, Paid in Sats: Iran Turns the Strait of Hormuz Into a Bitcoin Highway

Iran has officially gone full degen. The regime confirmed that bitcoin is now accepted as payment for cargo ships passing through the Strait of Hormuz, because why use traditional banking when you can use blockchain? Sometimes the best way to dodge sanctions is to just... not touch fiat at all.

The fee is $1 per barrel of oil, which means the largest tankers carrying up to two million barrels could be forking over a nice chunk of change in BTC or USD-pegged stablecoins. Not exactly chump change for a sanctions-hit nation. We're talking about a toll that would make even the most hardened crypto maxis nod in respectful approval.

This move isn't exactly surprising, according to Chainalysis. The Islamic Revolutionary Guard Corps has been quietly stacking crypto to facilitate cross-border oil sales for years. Andrew Fierman, head of national security intelligence at Chainalysis, said it's highly unsurprising this type of trade would happen via cryptocurrency, given Tehran's existing sanctions-skirting trade networks. In other words, they were already cooking with gas—now they're just cooking with on-chain gas.

The data backs it up. In December 2024, a U.S.-sanctioned IRGC-affiliated financier linked to the Iran-backed Houthi regime facilitated Iranian oil sales to Yemen involving crypto addresses totaling over $178 million in transfers in a single year. Then in April 2025, a broader network of Houthi financiers were purchasing weapons and commodities from Russia, with their crypto addresses included in a sanctions designation accounting for nearly a billion dollars in activity. That's not pocket change—that's a whole crypto treasury, and it's been busy.

The Houthis have also floated the idea of imposing a second shipping chokepoint at the Bab-al-Mandeb channel connecting the Red Sea to the Gulf of Aden. Because when you've got a good thing going, might as well double down. Two toll booths > one toll booth. Basic economics, really.

Fierman noted the IRGC has a whole network of crypto wallets facilitating this cross border activity. They don't even need traditional exchanges given the liquidity out there. It's basically the inverse of North Korea's crypto strategy, which is mostly about stealing and laundering billions rather than using it for legitimate trade. One team's HODLing, the other's rugging. Different vibes entirely.

Tom Keatinge from RUSI agreed that USD-backed stablecoins have become an increasingly important payment mechanism for the Iranian regime to avoid sanctions and western banking controls. He added that while stablecoin use might open users up to Western regulatory intervention, evidence suggests the risk is low. Lee Reiners from Duke University even suggested a cheeky scenario: if Iran demanded payment in the Trump family-affiliated USD1 stablecoin launched by World Liberty Financial, the U.S. President would have a direct financial incentive to lift sanctions. Now that's creative thinking. Sometimes the best way to predict the future is to just make it absurd enough that it becomes inevitable.

With about a fifth of the world's oil and liquefied natural gas passing through the Strait of Hormuz, this crypto toll system is basically a commercial-scale operation at this point. The blockchain just got a new highway, and it runs right through some very contested waters. Buckle up.
