Treasury Sanctions Expose Hundreds of Millions in Bitcoin Moving to Iran's IRGC
The US Treasury just put a number, if a vague one, on a story that has circulated for months: Iran has been running a real Bitcoin operation to fund itself, and it works.
THE DESIGNATION
On September 17, 2026, the Treasury's Office of Foreign Assets Control designated BitBank, an Iranian digital asset exchange it describes as a priority venture controlled by sanctioned financier Babak Zanjani, as part of Operation Economic Outcast. The same action named BitBank's software developer, Pishtaz Simorgh Electronic Trade Company, along with three Zanjani associates: Hossein Ali Zaker Hossein, Mohammad Mahdi Zaker Hossein, and Seyed Adel Heidari.
Today, the Department of the Treasury's Office of Foreign Assets Control designated BitBank, a priority digital assets venture controlled by OFAC-designated Iranian financier Babak Zanjani, as part of Operation Economic Outcast, the Trump Administration's whole-of-government economic campaign against the Islamic Republic of Iran and its enablers, and today's designations also include BitBank's developer, Pishtaz Simorgh Electronic Trade Company and three associates of Zanjani: Hossein Ali Zaker Hossein, Mohammad Mahdi Zaker Hossein, and Seyed Adel Heidari.
Treasury Secretary Scott Bessent framed the move bluntly. "Today's designations of Iranian digital asset infrastructure make perfectly clear that efforts to finance the Iranian regime using cryptocurrencies are not beyond OFAC's reach," said Secretary of the Treasury Scott Bessent.
THE HORMUZ MONEY TRAIL
The part of the release that matters for Bitcoiners is what it says about how the money actually moved. Treasury says Zanjani used BitBank between June and July 2026 to move hundreds of millions of dollars worth of Bitcoin to the Islamic Revolutionary Guard Corps, and the previously sanctioned Hormuz Safe Marine Services Authority has used BitBank since June to transfer payments it received to the Iranian regime.
Hormuz Safe Marine Services Authority is the entity that made headlines earlier this year for charging ships Bitcoin for safe passage through the Strait of Hormuz, a story many dismissed as a rumor without proof of real money changing hands. This designation is the closest thing to confirmation that has surfaced: Treasury itself is now saying the toll operation banked its Bitcoin through BitBank, and BitBank moved that Bitcoin on to the IRGC.
This is not Treasury's first pass at Zanjani's network. In January 2026, OFAC designated Zanjani himself alongside two UK-registered exchanges, Zedcex and Zedxion, alleging they laundered funds linked to the IRGC, and in July, Treasury designated additional companies and individuals tied to Zanjani's wider operation across Iran and offshore jurisdictions. BitBank is the latest and most direct target in that same network.
WHAT THIS DOES AND DOES NOT PROVE
Treasury did not publish a precise dollar figure for how much Bitcoin the IRGC now controls, and no official Iranian source has confirmed the size of any so-called strategic Bitcoin reserve. What Treasury's own language confirms is narrower and still significant: an exchange under Zanjani's control processed hundreds of millions of dollars in Bitcoin for the IRGC over a two-month window, and a sanctioned Hormuz toll operation used the same rails since June. The exact current size of Iran's Bitcoin holdings, whether from Hormuz tolls or from Bitcoin acquired over prior years, remains an open figure that neither Treasury nor Tehran has put a hard number on.
What the sanctions action did not do is touch the Bitcoin itself. Treasury shut down an exchange, the choke point where Bitcoin converts into usable local currency, not the underlying holdings or the network that moved them. That distinction is the entire story: Bitcoin's settlement layer stayed untouched while the off-ramp got sanctioned, which is exactly the failure mode Bitcoiners have pointed to for years when they say the coin itself is unconfiscatable even when the on-ramps and off-ramps are not.
WHY IRAN IS LEANING ON BITCOIN AT ALL
Iran's currency has been hyperinflating for months, and the country has been steadily cut off from Western payment rails through the broader Operation Economic Outcast campaign, which Bessent launched on August 24 as "Economic D-Day." A regime that cannot move money through traditional correspondent banking has an obvious incentive to use an asset that does not need a bank's permission to move across a border. That is the same property that makes Bitcoin attractive to a dissident, a remittance sender in a broken-currency country, or a sanctioned regime. The tool does not discriminate based on who is holding it.
The sanctions on BitBank do not end that dynamic. They raise the cost of using it. Every exchange the US designates forces the next transaction onto a slower, more self-custodial, harder-to-track path, which is a worse outcome for anyone trying to track the money, not a better one.
