U.S. Sanctions Iran’s Largest Digital-Asset Exchanges, Restricting Regional Bitcoin Access
The U.S. Treasury sanctioned Nobitex, Wallex, Bitpin, and Ramzinex as part of a campaign targeting Iranian digital-asset infrastructure. Although the action covered digital assets broadly, it materially affected major exchanges through which Iranian users accessed Bitcoin and other cryptocurrencies.
On June 2, 2026, the U.S. Department of the Treasury’s Office of Foreign Assets Control designated Nobitex, Iran’s largest digital-asset exchange, together with Wallex, Bitpin, and Ramzinex. Treasury described the action as part of “Economic Fury,” a sanctions campaign aimed at constraining Iranian financial networks, sanctions evasion, and transactions linked to the Islamic Revolutionary Guard Corps and other sanctioned actors.
The scale of the targeted infrastructure made the action more than a symbolic designation. Treasury identified Nobitex as Iran’s largest digital-asset exchange and said Wallex had received 12 percent of Iranian digital-asset inflows in 2025, while Bitpin had received 10 percent. Ramzinex, founded in 2018, had processed more than $2.45 billion in transactions. By designating several of the country’s most important exchanges at once, OFAC placed a large share of Iran’s formal digital-asset access layer under U.S. sanctions pressure.
The action was not Bitcoin-exclusive, and its historical significance should not be overstated as “Bitcoin regulation.” Its Bitcoin relevance came through market access. In Iran, where international banking restrictions and currency instability had long made digital assets useful for savings, settlement, and cross-border transfer, large domestic exchanges functioned as important gateways into Bitcoin as well as other assets. Sanctioning those gateways therefore changed the practical environment in which Iranian users and businesses could access Bitcoin liquidity and exchange services.
For the Bitcoin timeline, the event illustrates a broader evolution in sanctions policy. Governments were no longer focused only on individual blockchain addresses or isolated actors; they were increasingly willing to target national-scale digital-asset infrastructure. Bitcoin was not the sole subject of the action, but the mechanism affecting Bitcoin users was concrete and immediate: major regional access points were placed under sanctions.
