The U.S. Department of the Treasury’s Office of Foreign Assets Control designated an Iran-linked digital-asset exchange called BitBank on September 17 as part of “Operation Economic Outcast.”
The designation materially changes the sanctions risk for any exchange, custodian, OTC desk, payment provider or blockchain analytics team that encounters BitBank-linked counterparties, ownership structures or wallets.
Critical entity boundary: this is not Japanese bitbank, inc.
The Treasury action concerns the Iran-linked BitBank controlled by sanctioned financier Babak Zanjani as described in the OFAC notice.
It should not be confused with the Japanese cryptocurrency exchange bitbank, inc.
Entity matching must therefore use ownership, jurisdiction and identifiers rather than the display name alone.
What Treasury says BitBank did
Treasury says BitBank is controlled by Babak Zanjani, an Iranian financier previously designated by OFAC.
According to Treasury, Iran-linked entities used BitBank as part of payment and sanctions-evasion infrastructure; Hormuz Safe Marine Services Authority used BitBank to transfer payments received since June; and between June and July, Zanjani used BitBank to facilitate transfers of hundreds of millions of dollars’ worth of Bitcoin to the Islamic Revolutionary Guard Corps.
These are Treasury findings supporting the sanctions action.
Additional entities designated
OFAC also designated Pishtaz Simorgh Electronic Trade Company, identified as BitBank’s software developer, plus three Zanjani associates: Hossein Ali Zaker Hossein, Mohammad Mahdi Zaker Hossein and Seyed Adel Heidari.
The action therefore extends beyond one exchange brand into its operating/development network and associated individuals.
Legal basis and operational impact
Treasury says the entities were designated under Executive Order 13902.
As a general matter under OFAC blocking sanctions:
- property and interests in property of designated persons that are in the United States or in the possession/control of U.S. persons are blocked;
- blocked property must be reported to OFAC;
- entities owned 50% or more, directly or indirectly, by blocked persons can also be blocked even if not separately named;
- U.S. persons are generally prohibited from transactions involving blocked persons unless authorised or exempt.
Crypto businesses therefore need to screen customer identities, beneficial ownership, counterparty exchanges, wallet clusters and nested broker flows.
Why this matters to crypto compliance teams
Sanctions risk does not stop at a listed wallet address. Exchanges can rotate wallets, use omnibus accounts or transact through intermediaries.
The designation shows why sanctions controls need to combine entity intelligence, blockchain analytics, ownership mapping, transaction monitoring and enhanced due diligence.
What not to conclude
The designation does not mean every user who ever touched BitBank is automatically sanctioned, every downstream wallet is automatically blocked, Japanese bitbank, inc. is designated, or Treasury proved a criminal case in court.
Evidence Status
Confirmed / Official U.S. Treasury
BitBank was designated September 17; Treasury identifies it as Iran-linked and controlled by Babak Zanjani; Treasury says it was used for state-linked payments and Bitcoin transfers; its developer and three associates were also designated.
Requires Case-Specific Analysis
Whether a particular wallet belongs to BitBank, whether a downstream transaction is prohibited or blockable, and whether a non-U.S. party faces sanctions exposure.
Risk Assessment
High sanctions / counterparty risk.
What to Watch Next
OFAC wallet/address additions, exchange freezes, law-enforcement actions, partner de-risking, secondary-sanctions exposure and clarification of BitBank infrastructure.
