What happened.

The US Treasury sanctioned Iranian exchange BitBank over alleged bitcoin payments to the IRGC. According to the upstream summary, OFAC says the previously sanctioned Hormuz Safe maritime scheme routed payments through BitBank, moving hundreds of millions of dollars in bitcoin to the IRGC. The payment route and amount are OFAC’s claims as represented in the supplied record.

The record lists four supporting reports, including coverage by [The Block](https://www.theblock.co/news/regulation/2026-09-17-us-sanctions-iranian-crypto-exchange-bitbank-alleged-bitcoin-transfers-to-irgc-415462) and [CoinDesk](https://www.coindesk.com/policy/2026/09/18/iran-s-strait-of-hormuz-toll-booth-ran-through-a-bitcoin-exchange-u-s-says). Their titles align on the sanctions action, though the supplied material does not include the articles’ text.

Why it matters.

The designation puts a named exchange at the center of OFAC’s account of how the Hormuz Safe scheme received bitcoin payments. It gives counterparties a specific entity and alleged payment route to examine for compliance exposure.

The record does not identify transactions, wallet addresses, counterparties or the method behind the reported dollar amount. Those details would be needed to assess the claimed route and scale independently.

What to watch

Watch for an OFAC notice or supporting documentation that identifies the basis for BitBank’s designation and provides transaction details. Those receipts would help establish what OFAC can substantiate about the alleged transfers.
