US sanctions Iran-linked crypto exchanges

TLDR

The United States has added two Iran-linked crypto exchanges to its sanctions list, targeting how Tehran allegedly uses digital assets to move money and fund the Revolutionary Guard.

1. OFAC sanctioned Shelbit Exchange and Aban Tether, plus operator Siavash Kayvanpour, for laundering Iran-linked funds and supporting the Islamic Revolutionary Guard Corps (IRGC).
2. The move expands an ongoing campaign against Irans use of crypto, increasing compliance pressure on exchanges, stablecoin issuers and anyone touching higher risk counterparties.
3. Next steps include monitoring further OFAC designations, potential freezing of listed wallets, and how major global exchanges adjust screening of Iran-exposed flows.

Deep Dive

1. Who Was Sanctioned

The U.S. Treasurys Office of Foreign Assets Control (OFAC) sanctioned Georgia and UAE linked Shelbit Exchange and Iran-based Aban Tether, plus Iranian national Siavash Kayvanpour and several front companies. Reports state the platforms processed millions in digital assets for Iran, including flows tied to the Islamic Revolutionary Guard Corps, or IRGC, and previously sanctioned Iranian exchanges such as Nobitex, Wallex, Bitpin and Ramzinex. According to Treasury, IRGC-controlled wallets sent over $1 million in crypto to Shelbit-linked addresses and received more than $2 million back, while Aban Tether handled additional flows for already listed platforms. These entities are now on OFACs Specially Designated Nationals list, blocking their U.S. related assets and prohibiting U.S. persons from dealing with them.

2. Why It Matters For Crypto

This action builds on earlier OFAC measures against Iran-linked wallets, exchanges like Zedcex, Zedxio and Nobitex, and prior freezes of over $100 million in Iran associated crypto, as described in recent Treasury focused coverage. The signal to the industry is that regulators treat lightly regulated offshore exchanges, stablecoin rails and gambling linked flows as part of the same sanctions evasion problem. Non U.S. firms that continue servicing sanctioned entities risk secondary sanctions, loss of banking and delisting from major partners. For large exchanges and stablecoin issuers, this raises the bar on sanctions screening, chain analytics and counterparty due diligence, especially around high risk jurisdictions and mixers.

3. What To Watch Next

Future OFAC actions are likely to target additional exchanges, wallet clusters and shadow banking networks, as outlined in the broader Economic Fury campaign reporting. Watch for three things: further SDN list updates that add new exchanges or wallets, announcements from major stablecoin issuers about freezing tagged addresses, and compliance changes or delistings by large centralized exchanges following these designations. For markets, the direct volume impact is probably small, but the regulatory trend is clear toward tighter controls on cross border crypto liquidity linked to sanctioned states.

Confidence: high, based on OFAC linked reports and multiple independent news sources.

Conclusion

U.S. sanctions on Shelbit and Aban Tether deepen a long running effort to cut off Irans access to global finance through both traditional and crypto channels. While the immediate flows are modest compared with overall crypto volumes, the action raises regulatory risk for any venue that ignores sanctions exposure and pushes the industry toward more rigorous compliance and counterparty screening.
