The U.S. Treasury Department says it just shut down a crypto pipeline that let Iran’s most feared military force collect toll payments from ships passing through one of the world’s busiest oil routes.

Treasury sanctioned Iranian crypto exchange BitBank on September 17, tying it to already-sanctioned financier Babak Zanjani.
Officials say the platform moved hundreds of millions of dollars in Bitcoin to Iran’s Islamic Revolutionary Guard Corps (IRGC) between June and July.
BitBank allegedly processed payments ships made for safe passage through the Strait of Hormuz.
The move is part of a bigger crackdown called Operation Economic Outcast targeting Iran’s entire digital asset sector.

Treasury Targets Iran’s Crypto Lifeline

The U.S. Department of the Treasury’s Office of Foreign Assets Control (OFAC) announced sanctions on September 17 against BitBank, a cryptocurrency exchange it calls a “priority digital assets venture” controlled by Babak Zanjani. Zanjani, an Iranian financier already under U.S. sanctions, has long been accused of building networks that help Tehran dodge economic penalties. Treasury also sanctioned BitBank’s software developer and three people linked to Zanjani.

Officials say the exchange did more than trade coins. Treasury claims BitBank routed hundreds of millions of dollars in Bitcoin to the IRGC, Iran’s most powerful military and security force, between June and July of this year. The Islamic Revolutionary Guard Corps has been designated a terrorist organization by the United States, making any financial support for it a direct sanctions target.

A Toll Booth in the Strait of Hormuz

Beyond funding the IRGC, Treasury says BitBank processed payments tied to ship traffic through the Strait of Hormuz, a narrow waterway that carries a large share of the world’s oil shipments. According to Reuters, the exchange handled payments vessels made to pass through the strait safely. Treasury described BitBank as a key piece of Iran’s broader digital-asset sanctions-evasion system.

This “toll” arrangement suggests shipping companies paid to avoid trouble in waters where Iran has repeatedly threatened commercial vessels. If accurate, it means a crypto exchange helped turn a geopolitical chokepoint into a revenue source for a sanctioned regime, using digital coins instead of traditional bank wires that regulators can track more easily.

Part of a Bigger Crackdown

BitBank is not an isolated case. Treasury has steadily widened its crypto sanctions campaign against Iran throughout 2026, moving from single wallets to entire exchanges. In June, OFAC designated four major Iranian exchanges — Nobitex, Wallex, Bitpin, and Ramzinex — in what it called its largest enforcement action against Iran’s crypto sector at the time. In August, regulators blacklisted two more platforms, Shelbit and Aban Tether.

This pattern dates back further. OFAC first used cryptocurrency addresses as sanctions targets in 2018, during the SamSam ransomware case. Since then, the agency has grown far more aggressive, eventually declaring Iran’s entire digital asset sector “sanctionable” under an expanded executive order. BitBank’s designation fits neatly into that escalating timeline.

Why This Matters Beyond Crypto Markets

For everyday Americans, this story is about more than digital coins. It shows how sanctioned regimes adapt to pressure by using new financial tools that move faster than regulators can track. Whether someone leans left or right, most people share a basic frustration: government rules often lag behind the technology bad actors use to slip past them.

The Trump Administration frames Operation Economic Outcast as a “whole-of-government” effort to cut off Iran’s money supply. Supporters argue this shows the sanctions system finally catching up to crypto. Skeptics of any administration’s enforcement claims might note that these actions rely on Treasury’s own investigations, without independent court verification at this stage. Still, the underlying facts — the designation, the target, and the timing — are not in dispute.

As global attention stays fixed on the Strait of Hormuz, a chokepoint vital to oil markets everywhere, this case is a reminder that modern sanctions battles now play out as much on blockchain ledgers as they do on ocean waters.
