WASHINGTON, June 4, 2026
The U.S. Treasury sanctioned Nobitex and three other Iran-based crypto exchanges, escalating a digital-asset enforcement campaign as bitcoin traded near $64,000 and regulators pushed sanctions risk deeper into global stablecoin and exchange rails.
Treasury’s Office of Foreign Assets Control said on June 2 that it designated Nobitex, Wallex, Bitpin and Ramzinex as part of “Economic Fury,” the administration’s pressure campaign against Iran, according to the Treasury announcement.
The action is not only a blacklist entry. It puts a large slice of Iran’s domestic crypto market into the sanctions perimeter and warns overseas financial firms that transactions with the named exchanges can create exposure even when those firms are outside the United States.
Market snapshot: Bitcoin traded near $64,000, while ether was near $1,800. Treasury said Nobitex processed more than 50% of all Iranian digital asset inflows in 2025, Wallex received 12%, Bitpin received 10%, and Ramzinex has processed more than $2.45 billion in transactions.
Treasury Secretary Scott Bessent framed the move as a follow-the-money campaign. “Treasury will continue to follow the money,” he said in the announcement, referring to both banking channels and digital assets.
Nobitex sanctions hit Iran’s main crypto rail
Treasury described Nobitex as Iran’s largest digital asset exchange and said it facilitated payments tied to sanctions evasion, terrorist activity and Islamic Revolutionary Guard Corps-linked transactions, including activity associated with ransomware actors.
The agency also said Nobitex helped the Central Bank of Iran access hundreds of millions of dollars in stablecoins used to support the rial, and that the exchange helped regime insiders reach international digital asset exchanges.
OFAC named Nobitex under counterterrorism authority and under Executive Order 13902, which targets parties operating in Iran’s financial sector. It also designated Amir Hossein Rad, Nobitex’s chairman, co-founder and former CEO, plus several other Nobitex officials.
The June action follows a string of Iran-linked crypto enforcement moves. Treasury said Rad helped Nobitex reconstitute operations after a $90 million hack on June 18, 2025, making the new designation both a sanctions case and a reminder that exchange infrastructure can become a geopolitical target.
The subject overlaps with a broader sanctions theme Daily Crypto Briefs flagged earlier, when Iran’s defense export portal listed crypto payments as an option for contracts tied to missiles and drones. The new Treasury action gives that risk a named exchange layer.
OFAC warning broadens risk beyond U.S. firms
OFAC’s added guidance makes the action more important for crypto compliance teams than a typical domestic designation. In FAQ 1257, the agency said foreign financial institutions and other non-U.S. persons that engage in certain transactions with Nobitex, Wallex, Bitpin or Ramzinex can face sanctions exposure.
That means a non-U.S. exchange, broker, bank, payment firm or stablecoin intermediary may need to check not only whether a wallet appears on a sanctions list, but whether counterparties have indirect exposure to the exchange cluster.
OFAC said it can designate parties that materially assist the named exchanges or impose strict conditions on correspondent and payable-through accounts for foreign financial institutions that knowingly facilitate significant transactions for them.
TRM Labs said the four designated exchanges accounted for roughly $7.7 billion, or 78%, of Iran’s attributed crypto volume in 2025, according to its June 3 analysis. TRM put Nobitex’s 2025 volume at $4.7 billion and said the platforms span millions of addresses across Bitcoin, Ethereum and Tron.
Those numbers explain why the order can ripple beyond Iran. The same compliance architecture that screens scams, hacks and ransomware must also absorb state-linked exchange risk, a pressure point that sits next to the cybercrime losses covered in our report on $605 million in recent crypto attacks.
Stablecoins move to center of sanctions enforcement
The stablecoin angle is the operational center of the case. Treasury said Nobitex helped the Central Bank of Iran access hundreds of millions of dollars in stablecoins, while Chainalysis said the designation was the largest Treasury action yet against Iran’s digital asset economy in its analysis of the sanctions.
Chainalysis said Iran’s crypto ecosystem reached more than $7.78 billion in 2025 and estimated that addresses associated with the IRGC accounted for more than half of total value received by the Iranian crypto ecosystem in the fourth quarter of 2025.
The enforcement logic is straightforward: stablecoins can move dollars quickly, but large issuers, exchanges and custodians also create points where sanctioned exposure can be screened, frozen or reported. That makes dollar tokens useful to both users seeking hard-currency access and authorities seeking leverage over identifiable intermediaries.
For U.S. policy, this is another reminder that crypto regulation is not only about the SEC, the CFTC or market structure bills. Treasury’s sanctions and anti-money-laundering powers are a separate lane, as outlined in our 2026 U.S. crypto regulation guide.
What remains unclear is how many wallets tied to the four exchanges will be publicly identified, whether additional foreign counterparties will be named, and how quickly stablecoin issuers and exchanges will update screening rules. The next signals to watch are OFAC list updates, new FAQs, issuer freeze disclosures and any secondary-sanctions action against firms that keep routing activity for the named Iranian exchanges.
