Why Did OFAC Target BitBank?
The U.S. Treasury Department has sanctioned Iranian cryptocurrency exchange BitBank, alleging the platform was used to transfer hundreds of millions of dollars in bitcoin to the Islamic Revolutionary Guard Corps.
The Office of Foreign Assets Control designated BitBank on September 17 alongside its software developer, Pishtaz Simorgh Electronic Trade Company, and three associates of Iranian financier Babak Zanjani: Hossein Ali Zaker Hossein, Mohammad Mahdi Zaker Hossein and Seyed Adel Heidari.
Treasury described BitBank as a digital asset venture controlled by Zanjani, who has previously been sanctioned by OFAC. According to the agency, Zanjani used BitBank between June and July to facilitate transfers of hundreds of millions of dollars worth of bitcoin to the IRGC.
BitBank’s developer, Pishtaz Simorgh, is a subsidiary of the previously sanctioned Dot One Value Creation Group. Treasury said the three individuals designated Thursday are executives or associates within Zanjani’s wider business network.
“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,” Treasury Secretary Scott Bessent said. “If you support the Iranian regime, the Department of the Treasury will sanction you.”
How Does Hormuz Safe Fit Into the Crypto Network?
The action also connects BitBank to Hormuz Safe Marine Services Authority, a previously sanctioned Iranian digital platform linked to shipping through the Strait of Hormuz.
Treasury said Hormuz Safe has used BitBank since June to transfer payments it collected. The agency previously described Hormuz Safe as a digital maritime services business accepting bitcoin and other digital assets for services connected with vessels transiting the Strait of Hormuz.
That link broadens the significance of the BitBank action beyond a single exchange. The U.S. allegation describes a network in which digital assets can move between commercial platforms, shipping-related services and entities tied to sanctioned Iranian financial networks.
For crypto businesses dealing with Iranian counterparties, the issue is therefore increasingly one of exposure across connected entities rather than simply whether a wallet or exchange itself has already appeared on an OFAC list.
Investor Takeaway
The BitBank designation shows how U.S. sanctions enforcement is moving beyond individual wallets toward exchanges, developers and businesses that Treasury says form part of the same payment network. That raises screening and counterparty risks for exchanges, stablecoin issuers and service providers handling transactions linked to Iran.
How Broad Is the U.S. Crackdown on Iranian Crypto Platforms?
BitBank is the latest crypto platform targeted during a series of U.S. sanctions actions against Iranian digital asset businesses in 2026.
OFAC sanctioned Nobitex, Wallex, Bitpin and Ramzinex in June. Treasury said Nobitex handled more than half of Iranian digital asset inflows during 2025 and alleged that the exchange processed transactions linked to the IRGC and other sanctioned entities.
The agency followed in August with sanctions against Shelbit and Aban Tether. Aban Tether was accused of processing transactions involving previously sanctioned Iranian exchanges, while Shelbit was linked by Treasury to money flows involving online gambling operations and sanctioned actors.
The September BitBank action falls under Operation Economic Outcast, a Treasury campaign launched on August 24 targeting financial channels and businesses the U.S. government says assist Iranian sanctions evasion.
The repeated use of sanctions against exchanges and their associated corporate structures suggests Treasury is concentrating increasingly on the infrastructure that allows digital assets to move between Iranian businesses and international counterparties.
What Does the BitBank Designation Mean for Crypto Firms?
OFAC designation carries direct consequences for businesses subject to U.S. sanctions rules. Property and interests in property belonging to the designated parties that are located in the U.S. or controlled by U.S. persons must be blocked and reported to OFAC.
Companies owned 50% or more, directly or indirectly, by blocked persons can also be treated as blocked even if they are not separately named on the sanctions list.
That makes ownership structures and transaction counterparties increasingly important for exchanges, custodians and blockchain compliance providers. A platform may face sanctions exposure not only through direct dealings with a named entity but also through companies controlled by sanctioned individuals or businesses.
The BitBank action also reinforces the role blockchain transactions are playing in sanctions enforcement. Digital asset transfers may operate outside conventional banking rails, but their links to exchanges, developers and identifiable corporate networks can still give authorities routes for financial restrictions.
For crypto companies operating internationally, the practical issue is becoming less about whether sanctions enforcement reaches digital assets and more about how far regulators trace the networks surrounding them.
