US Treasury Sanctions Iran Exchange BitBank Over Bitcoin

The US Treasury sanctioned Iranian crypto exchange BitBank on 17 September 2026, accusing it of moving bitcoin for Iran's Revolutionary Guard. Wallet users everywhere should note it: Washington is now targeting exchanges themselves, not just the addresses they touch.

What actually happened

According to The Block, Treasury designated BitBank on 17 September 2026. The agency alleges BitBank processed bitcoin transfers connected to Iran's Islamic Revolutionary Guard Corps. Treasury said Hormuz Safe, a platform already under sanction, used BitBank to move payments it had collected since June 2026. The report does not list transfer amounts, exact dates beyond June, or named Treasury officials. BitBank's size, user count, and home jurisdiction are not detailed in available reporting. What is confirmed: a sanctioned Iranian platform routed funds tied to a designated military body through this exchange.

How we got here

Hormuz Safe was sanctioned before this action, though the exact date is not given in current reporting. This new designation reaches past that platform to the exchange rail it relied on to move money since June. That marks a shift from targeting end-use platforms to targeting the exchange infrastructure beneath them. BitBank's founding, headquarters, and prior regulatory record are not disclosed in the source material, leaving its full history before this action unclear.

Why this matters for you

For everyday wallet holders, this adds a new screening risk. If funds pass through BitBank or Hormuz Safe addresses, even unknowingly, compliant exchanges may flag or freeze them. Bonuz users moving crypto across chains should expect stricter address checks from partner exchanges and on-ramps. Builders integrating exchange rails should review counterparty exposure to Iran-linked platforms now, before a similar designation lands closer to home. Expect more screening prompts and delays at centralized on-ramps in coming weeks.

The bigger question

Can sanctions on exchanges actually stop bitcoin from reaching designated groups, or do public blockchains simply push transfers toward harder-to-trace intermediaries? BitBank's case will show whether choking one exchange slows the flow or just reroutes it.

What to watch

Treasury has not set a compliance deadline or court date in the material reviewed. Watch for further designations naming exchanges linked to Hormuz Safe, and for whether other platforms delist Iran-linked addresses. Bonuz will track new Treasury actions on crypto exchanges as they are confirmed by primary sources.
