U.S. Treasury Imposes Sanctions on Iran's Largest Crypto Exchange, Nobitex, and Key Executives

The U.S. Department of the Treasury has taken significant action against Iran's digital financial sector, sanctioning Nobitex, the country's largest cryptocurrency exchange, along with three other platforms and several key individuals. This move marks an escalation in the U.S. government's "maximum pressure" campaign against Tehran.

Targeting Illicit Financial Networks

This week's designations include Nobitex, which reportedly processed over 50% of all Iranian digital asset inflows in 2025. The Treasury alleges that Nobitex has served as a conduit for payments tied to Iran's Islamic Revolutionary Guard Corps (IRGC), ransomware operations, and efforts to safeguard regime wealth during internet blackouts. Treasury Secretary Scott Bessent stated that while Iran's economy faces significant challenges, the regime has opted to use digital asset technologies for illicit purposes, including evading sanctions and transferring wealth out of the country.

Beyond Nobitex, the sanctions also hit Wallex, Iran's second-largest crypto exchange by volume, which reportedly received 12% of Iranian digital asset inflows and facilitated IRGC-linked transactions. Bitpin, accounting for 10% of inflows, is said to have backers connected to Iranian sanctions evasion. Additionally, Raminex, founded in 2018, processed over $2.45 billion in transactions, including for a government-backed Iranian financial institution. Blockchain analytics firm Elliptic has linked Nobitex to a network consistent with IRGC financial activity. In April 2026, Tether froze $344.2 million across wallets attributed to the Central Bank of Iran, with ties to the IRGC-Qods Force and Hizballah, marking a significant on-chain freeze. The U.S. has reportedly seized approximately $1 billion in Iranian cryptocurrency.

A Shift Towards Individual Accountability

What sets this round of sanctions apart is the direct targeting of individuals. Amir Hossein Rad, Nobitex's chairman, co-founder, and former CEO, was designated. He was notably involved in reconstituting Nobitex's operations after a $90 million hack in June 2025. Also named were two co-founders from the Kharrazi family, reportedly connected to former Supreme Leader Khamenei's inner circle, and the current CEO, Seyed Ali Khoee.

This strategy signals a pivot towards holding executives personally accountable, rather than just platforms. Analysts suggest this approach carries more deterrent weight, as it threatens individuals with personal asset freezes and exposure to secondary sanctions. This could have a broader impact across the industry.

Broader Implications of Treasury's Actions

The Treasury invoked two executive orders for these designations: E.O. 13224 (a counterterrorism authority) and E.O. 13902 (targeting Iran's financial sector). Both orders result in the blocking of all U.S. property interests belonging to the named entities and individuals. Furthermore, any foreign company or financial institution continuing to engage with them risks exposure to secondary sanctions. This move intensifies the scrutiny on global financial entities, including stablecoin issuers.

Compliance professionals are closely watching to see if these explicit designations will compel stablecoin issuers and foreign exchanges to broadly restrict services for Iranian users. While OFAC clarified earlier that Iranian digital asset exchanges are considered blocked financial institutions regardless of being on the SDN list, a direct SDN designation triggers secondary sanctions against global counterparties and provides clear legal justification for bulk freezes. The Treasury has also cautioned against facilitating payments through the Strait of Hormuz, designating the "Persian Gulf Strait Authority" in May 2026 for its alleged role in extorting international shipping. This comprehensive approach underscores the U.S. commitment to combating illicit finance within the crypto space, drawing attention to the complexities of global crypto regulation.

Key Takeaways:

• U.S. Treasury sanctioned Nobitex and three other Iranian crypto platforms.
• Key executives, including Amir Hossein Rad, were also targeted.
• Actions aim to curb alleged funding for IRGC and sanctions evasion.
• This marks a strategic shift to hold individuals personally accountable.
• Foreign entities face secondary sanctions for continued dealings.
