US Treasury Sanctions Iranian Crypto Exchanges Including Nobitex for Terrorist Financing

The U.S. Treasury Department’s Office of Foreign Assets Control designated Nobitex, Iran’s largest digital asset exchange, along with three other Iranian cryptocurrency platforms for allegedly facilitating terrorist financing and sanctions evasion.

The Treasury Department alleges Nobitex processed more than 50% of all Iranian digital asset inflows in 2025 and facilitated payments tied to Iran’s terrorist activities, sanctions evasion efforts, and Islamic Revolutionary Guard Corps-linked transactions, including IRGC-affiliated ransomware actors.

The exchange also helped the Central Bank of Iran access hundreds of millions of dollars in stablecoins used to prop up the plummeting value of the Iranian rial, the Treasury alleged in the sanctions announcement.

Wallex, Iran’s second-largest digital asset exchange by volume, received 12% of Iranian digital asset inflows in 2025. Bitpin, which accounts for 10% of such inflows, faced sanctions for having investors reportedly linked to Iranian sanctions evasion efforts. Ramzinex, a Tehran-based digital asset exchange founded in 2018, processed over $2.45 billion in transactions.

The Treasury Department also sanctioned four individuals connected to Nobitex, including chairman and co-founder Amir Hossein Rad, who helped reconstitute operations following a $90 million hack in June 2025. Two co-founders, Seyed Mohammad Ali Aghamir and Seyed Mohammad Aghamir Mohammad Ali, are members of the Kharrazi family, part of Supreme Leader Khamenei’s inner circle. Current Nobitex CEO Seyed Ali Khoee, who previously served as director of product and marketing, was also designated.

Monday’s sanctions mark the latest enforcement action in the Treasury’s campaign against Iranian crypto assets.

Treasury Secretary Scott Bessent said last week that his department had seized around $1 billion in cryptocurrency from Iranian exchanges and wallets since the beginning of its enforcement campaign against Iran. In April, Tether froze $344.2 million in stablecoins held across two wallets attributed to the Central Bank of Iran.

“As promised, Treasury will continue to follow the money in support of Economic Fury, whether it is through the banking system or through digital assets, to prevent the regime from developing a nuclear weapon,” Bessent said in the Treasury statement.
