US Treasury sanctions Iranian crypto exchange network

TLDR

The U.S. Treasury has sanctioned an Iran-linked crypto exchange network centered on BitBank for allegedly moving hundreds of millions of dollars in Bitcoin to sanctioned entities.

1. BitBank, its developer and several associates of financier Babak Zanjani were added to OFAC's SDN list under Operation Economic Outcast targeting Iran's digital asset sector.
2. Sanctions bar US persons from transacting with the network, freeze any assets in US jurisdiction, and pressure global exchanges and stablecoin issuers to blocklisted wallets.
3. For crypto users, this reinforces that regulated platforms must treat Iranian flows as high-risk and that more exchange and wallet designations are likely if evasion continues.

Deep Dive

1. What Treasury Actually Did

The U.S. Treasury blacklisted Iranian crypto exchange BitBank, its software developer Pishtaz Simorgh Electronic Trade Company and three associates of Babak Zanjani for sanctions evasion, alleging they moved hundreds of millions of dollars in Bitcoin to Irans Islamic Revolutionary Guard Corps using the platform blacklisted Iranian crypto exchange BitBank.

BitBank is accused of routing payments for the already-sanctioned Hormuz Safe Marine Services Authority and has now been designated under Executive Order 13902 as part of Operation Economic Outcast, a campaign that explicitly pulls Irans digital asset sector into the sanctions perimeter sanctioned Iranian cryptocurrency exchange BitBank.

Zanjani himself is described by US authorities as a convicted sanctions evader who has rebuilt a digital asset business network, with BitBank promoted through his broader corporate group.

2. How OFAC Sanctions Hit Crypto Infrastructure

OFACs designation places BitBank and related entities on the Specially Designated Nationals list, meaning US persons are generally prohibited from any transactions with them and any assets under US jurisdiction are blocked BitBank placed on the SDN list.

In practice this translates into several crypto-specific effects: compliant exchanges and custodians must screen for BitBank-related names and wallet addresses, stablecoin issuers are expected to freeze tokens controlled by listed parties, and analytics firms expand tracing of known Iranian networks.

Foreign financial institutions and platforms that facilitate significant transactions for these actors also face secondary sanctions risk under EO 13902, which can include loss of access to US dollar banking, so most major venues will avoid direct exposure.

3. Broader Pattern And What To Watch

This is not an isolated move. Earlier in 2026 Treasury sanctioned Iranian exchanges Nobitex, Wallex, Bitpin and Ramzinex, with Nobitex reportedly handling more than half of Irans crypto inflows in 2025 %%CKPROTECTED0%%.

Blockchain intelligence analysis links BitBank to a wider IRGC-related network, including exchanges Zedcex and Zedxion that processed about 1 billion dollars of IRGC-linked activity, underscoring officials view of Iranian crypto infrastructure as part of sanctions evasion rather than neutral market plumbing broader IRGC-linked crypto network.

Looking ahead, the important signals are further OFAC wallet listings, new exchange designations, and any guidance on wind-down or humanitarian exceptions, all of which will shape how strictly global platforms treat Iranian-origin digital asset flows.

Conclusion

By sanctioning an Iranian crypto exchange network, Washington is extending traditional Iran policy into the digital asset layer, treating exchanges, developers and wallets as part of the same enforcement system.

For everyday crypto users, this mainly shows up through tighter compliance at major platforms and higher risk attached to Iranian-linked venues, rather than changes to Bitcoins underlying protocol, but more infrastructure listings could keep this a live regulatory theme.
