The U.S. Treasury blacklisted Nobitex, Iran’s largest cryptocurrency exchange, on June 2, 2026, along with three other domestic platforms accused of moving money for the Iranian regime. The Office of Foreign Assets Control (OFAC) added Nobitex, Wallex, Bitpin and Ramzinex, plus several of their executives, to its Specially Designated Nationals list, citing ransomware payments, sanctions evasion and ties to the Islamic Revolutionary Guard Corps. Treasury called the move part of its “Economic Fury” campaign against Tehran. The designation lands days after the department said it had seized roughly $1 billion in Iranian crypto, and it cuts the four exchanges off from any business touching the U.S. dollar.
The Specially Designated Nationals (SDN) list is a U.S. blacklist that bars Americans and dollar-based institutions from transacting with named entities and freezes any assets within U.S. reach.
Key takeaways
- OFAC sanctioned Nobitex, Wallex, Bitpin and Ramzinex on June 2, 2026, the largest U.S. action yet against Iran’s crypto economy.
- Nobitex handled more than 50% of all Iranian digital asset inflows in 2025; Wallex took 12% and Bitpin 10%.
- Four individuals were named, including chairman and co-founder Amir Hossein Rad and current CEO Seyed Ali Khoee.
- The designations create secondary sanctions risk for any global exchange or bank still processing transactions for the four platforms.

What happened and why it matters
OFAC’s action targets the on-ramps that connect ordinary Iranians, and the state, to global crypto markets. Nobitex alone processed more than half of the country’s digital asset inflows in 2025, according to Treasury and blockchain analytics firms reviewing the designation. Wallex accounted for roughly 12% and Bitpin about 10%, making the four-exchange sweep a strike at the core of Iran’s domestic crypto plumbing rather than a single bad actor.
Treasury said Nobitex processed payments tied to Iran’s terrorist activities, IRGC-linked transfers and ransomware operators, and that it helped the Central Bank of Iran access hundreds of millions of dollars in stablecoins. The press release also alleged the exchange moved wealth out of the country during internet blackouts and after U.S. strikes earlier in the year. “While Iran’s economy is in free fall, the regime has chosen to co-opt digital asset technologies for its own corrupt agenda,” Treasury Secretary Scott Bessent said in a statement.
The impact on traders, exchanges and the regime
For the platforms themselves, the designation is close to a death sentence in dollar terms. Any stablecoin issuer, custodian or offshore exchange that continues to clear transactions for the four names now risks being cut off from the U.S. financial system itself. That secondary sanctions exposure is what pushes compliance teams at firms like Tether, Circle, Binance and Coinbase to freeze related wallets and screen for connected addresses, often within hours of a designation.
Iranian users face the more immediate squeeze. With the largest local exchanges blacklisted, retail traders lose the simplest path to convert rials into crypto and back, and any holdings flagged as linked to the sanctioned entities can be frozen by compliant counterparties. On-chain, the practical effect is that funds sitting in or routed through these exchanges become harder to spend anywhere that follows OFAC rules, even if the tokens themselves keep moving.
The market reaction was muted, in part because the news arrived during a broader sell-off that pushed bitcoin toward its 2026 lows. Sanctions on regional exchanges rarely move major coin prices, but they steadily raise the cost and risk of using crypto to dodge U.S. restrictions, the outcome Treasury is after.
The regulatory angle and what comes next
The Nobitex designation is the latest layer in a months-long enforcement push that has paired asset seizures with blacklistings. It follows the late-May announcement that Treasury had seized about $1 billion in Iranian crypto, and it fits a pattern of using OFAC’s blacklist to isolate financial infrastructure rather than chase individual wallets. Compliance firms expect further designations as investigators trace funds that flowed through the four exchanges to downstream counterparties abroad.
For the wider industry, the action is another reminder that crypto rails are now squarely inside the sanctions regime. Exchanges with any Iranian exposure will need to re-screen customers and freeze flagged balances, and stablecoin issuers, the rails Treasury says Tehran exploited, face renewed pressure to show they can block sanctioned use. Expect the secondary sanctions warning to ripple through offshore venues that have historically served Iranian traders.
Frequently asked questions
What did OFAC actually do to Nobitex?
OFAC added Nobitex and three other Iranian exchanges to the Specially Designated Nationals list on June 2, 2026. That bars U.S. persons and dollar-based institutions from dealing with them and freezes any assets within U.S. jurisdiction, effectively cutting the platforms off from the global dollar system.
Why were the other exchanges sanctioned too?
Wallex, Bitpin and Ramzinex together handled a large share of Iran’s crypto inflows alongside Nobitex. Treasury treated the four as connected infrastructure that helped the regime evade sanctions and move funds, so it designated them as a group rather than targeting one platform.
Does this affect crypto prices or U.S. users?
Major coin prices saw little direct impact. The bigger effect is on compliance: global exchanges and stablecoin issuers must screen for and freeze funds linked to the sanctioned entities, raising the risk for anyone who keeps transacting with them.
