US expands Iran sanctions to digital assets

TLDR

The US has formally added Irans digital asset sector to its sanctions regime, making crypto activity tied to Iran a direct target for enforcement.

1. Treasury issued a new determination under Executive Order 13902 that lets OFAC sanction any person worldwide operating in or supporting Irans digital asset sector.
2. Global exchanges, OTC desks, payment processors and even DeFi front ends now face higher sanctions and compliance risk if they touch Iran-linked flows, though ordinary retail users are not the direct target.
3. The impact will depend on how aggressively OFAC names specific wallets, platforms and intermediaries, plus how major players like China and large exchanges respond over the coming months.

Deep Dive

1. New Authority Over Irans Crypto Sector

On 24 Aug 2026, the US Treasury expanded sanctions to Irans digital asset sector, adding crypto to a list of targeted sectors that already included technology, gold, aviation and shipping under Executive Order 13902.

The sectoral determination lets the Office of Foreign Assets Control (OFAC) sanction any foreign individual or company that operates in or provides services supporting Irans digital asset sector, regardless of where they are based. Nearly 60 entities, individuals and vessels were designated in this wave, including UAE-based broker Ivan Obukhov and his firm Foscom FZE, which Treasury alleges processed over $100 million in crypto for oil sales linked to Irans Revolutionary Guard.

Importantly, this does not automatically sanction every crypto firm serving Iranian users; OFAC still has to name specific parties before blocking rules apply.

2. How It Hits Crypto Infrastructure

For crypto businesses, this is primarily a sanctions and anti-money-laundering issue, not a direct price shock. Treasury and OFAC have already sanctioned Iranian exchanges like Nobitex, Wallex, Bitpin, Ramzinex, Shelbit and Aban Tether for facilitating Iran-linked flows, and this new framework explicitly treats digital assets as a sanctionable sector.

Exchanges, custodians, OTC brokers, wallet providers and analytics firms with US exposure now need tighter screening of customers, counterparties and wallet addresses to avoid secondary sanctions, including potential loss of access to US banking. DeFi front ends and routing services are not exempt in principle if they knowingly facilitate transactions for designated Iranian entities.

3. What To Watch Next

Reporting indicates this is part of Operation Economic Outcast, a broader campaign to sever Irans financial lifelines, with officials signaling more Iran-related crypto designations are likely.

Outside the US, China has publicly pushed back against the expanded sanctions, arguing that its Iran cooperation is lawful, but Chinese entities that touch Iran-related digital asset flows could still face US secondary sanctions. Major centralized exchanges and stablecoin issuers are likely to update their sanctions policies, wallet blacklists and geo-blocking, which will shape how visible the impact becomes for everyday users.

Conclusion

The expansion of Iran sanctions into digital assets turns crypto rails from a grey area into an explicitly named enforcement channel, raising compliance stakes for exchanges and intermediaries worldwide.

If OFAC follows through with detailed wallet and platform designations, this campaign could materially reshape how cross-border crypto payments interact with sanctioned jurisdictions, even if headline prices barely move in the short term.
