The U.S. Treasury Department on June 2 sanctioned four Iranian cryptocurrency exchanges, Nobitex, Bitpin, Ramzinex, and Wallex, accusing them of facilitating sanctions evasion and supporting the Iranian regime’s financial infrastructure.
What the Treasury action covers
The Office of Foreign Assets Control (OFAC) designated all four exchanges alongside four Iranian nationals, including Nobitex co-founder and CEO Amir Hossein Rad and two Kharrazi-family brothers tied to the exchange.
Treasury singled out Nobitex as Iran’s largest digital asset platform, stating it processed over 50% of all Iranian digital asset income in 2025 and provided significant support to the regime’s sanctions-evasion network.
The department also accused Nobitex of helping move and protect regime wealth after U.S. combat operations in Iran, even during internet blackouts, according to Reuters reporting.
Which exchanges are affected and how they rank
Beyond Nobitex’s dominant position, Treasury broke down market share for the three smaller platforms. Wallex received 12% and Bitpin 10% of all Iranian digital asset inflows in 2025, giving the four sanctioned exchanges collective control over more than 72% of Iran’s crypto volume.
Ramzinex, the fourth exchange, has processed over $2.45 billion in crypto transactions since 2018, according to Treasury’s designation.
Blockchain analytics firm Elliptic reported earlier that the Central Bank of Iran had acquired at least $507 million in crypto via Tron by the end of June 2025, with at least $387 million in USDT passing through Nobitex specifically.
The OFAC designation means any U.S. person or entity transacting with these exchanges, their listed operators, or associated wallet addresses faces potential sanctions violations. Global counterparties with U.S. exposure will likely sever connections to the four platforms.
Why the sanctions matter for crypto markets
The action is the most sweeping U.S. sanctions move targeting crypto infrastructure in Iran to date. By naming four exchanges that collectively handled the majority of Iran’s digital asset flows, Treasury is signaling that crypto-based sanctions evasion is a top enforcement priority.
John Reed Stark, a former SEC official, framed the stakes bluntly in comments reported by Reuters via Investing.com:
“The entities doing crypto financing through these platforms are the very ones that the president is trying to defeat in the war.”

The move comes as U.S. lawmakers advance new crypto compliance frameworks. The CLARITY Act recently reached the Senate calendar after committee approval, and regulators are increasingly looking at how exchanges handle jurisdictional risk, an area where derivatives platforms filing for new product approvals will also face scrutiny.
For the broader market, the sanctions add to a risk-off atmosphere. Bitcoin traded at roughly $67,621 at the time of the announcement, down 4.7% over 24 hours, while the Fear & Greed Index sat at 23, deep in “Extreme Fear” territory. Institutional players like Strive, which recently added 2,500 BTC to its treasury, continue accumulating despite the macro headwinds.
Industry observers will be watching whether OFAC follows up with secondary sanctions on non-U.S. entities that continued routing volume through the four exchanges. Any wallet addresses tied to Nobitex, Wallex, Bitpin, or Ramzinex are now potential compliance tripwires for every exchange and OTC desk with U.S. touchpoints.
