US sanctions Iranian crypto exchange network

TLDR

The U.S. Treasury has sanctioned Iranian crypto exchange BitBank and related entities for allegedly sending hundreds of millions of dollars in bitcoin to Irans Revolutionary Guard.

1. BitBank, its software developer and close associates of financier Babak Zanjani were designated after alleged bitcoin transfers to the Islamic Revolutionary Guard Corps.
2. The move extends ongoing U.S. campaigns against Irans digital asset infrastructure, following sanctions on other Iran-based exchanges earlier this year.
3. Exchanges and users globally face higher compliance pressure, as Washington signals that crypto based sanctions evasion will be treated like traditional finance violations.

Deep Dive

1. What Was Sanctioned

According to the U.S. Treasury, Iranian crypto exchange BitBank was sanctioned after allegedly facilitating hundreds of millions of dollars in bitcoin transfers to the Islamic Revolutionary Guard Corps, a U.S.-designated terrorist organization, between June and July. Treasury also designated BitBanks software developer Pishtaz Simorgh Electronic Trade Company and three close associates of Iranian financier Babak Zanjani, who controls BitBank as a priority digital asset venture within his sanctions evasion network.

Officials say Hormuz Safe Marine Services Authority has used BitBank since June to route payments to the regime via a bitcoin settled platform tied to shipping coverage in the Strait of Hormuz, targeting more than 10 billion dollars in revenue. These details are outlined in Treasury focused reporting on the BitBank action by The Block and others.

2. Part Of Wider Crackdown

This designation is not isolated. U.S. authorities had already hit Irans largest crypto exchange Nobitex and platforms such as Wallex, Bitpin and Ramzinex, alleging they processed a large share of Irans digital asset inflows and IRGC related activity, under earlier Economic Fury actions. The BitBank move is described as part of Operation Economic Outcast, a broader effort to disrupt Irans financial and logistics networks that use digital assets.

Treasury Secretary Scott Bessent stated that these Iranian digital asset designations show that efforts to finance the Iranian regime using cryptocurrencies are not beyond OFACs reach, underscoring that crypto rails are now firmly within the sanctions enforcement perimeter.

3. Impact On Crypto Market

Practically, an OFAC designation means U.S. persons must stop dealing with the listed entities, any property under U.S. jurisdiction is blocked, and secondary exposure risk rises for non U.S. firms that choose to interact with them. Major exchanges, custodians and compliance vendors are likely to further tighten Iran related controls, including screening counterparties and flows linked to BitBank and its network.

For ordinary users, direct impact is limited unless they use Iran based platforms or routes that touch them, but the signal is clear: regulators view crypto based sanctions evasion as a high priority, and compliant venues will increasingly distance themselves from opaque cross border infrastructure.

Conclusion

The BitBank sanctions show U.S. authorities treating Iranian crypto infrastructure as an extension of its traditional sanctions targets, not as a loophole. For the broader market, this reinforces a trajectory where large, regulated platforms invest heavily in sanctions and AML controls, while users and smaller venues face growing pressure to prove that their flows are not part of state backed evasion networks.
