Nobitex Sanctioned, CoinEx Tightens Controls
The findings arrive against a backdrop of intensifying US enforcement. On June 2, 2026, the Treasury Department's Office of Foreign Assets Control (OFAC) designated Nobitex, along with three other Iranian digital asset exchanges, as part of the Trump administration's Economic Fury campaign targeting the Iranian regime's use of digital assets for sanctions evasion and terror finance.
In response to the scrutiny, CoinEx has moved to implement enhanced Know Your Customer protocols and has restricted access for users based in Iran, though critics have characterised these steps as reactive rather than proactive.
Scale Could Be Far Larger
The $3.84 billion figure is likely a conservative estimate. Privacy tools and peer-to-peer transactions remain difficult to trace, meaning the true volume of Iran-linked flows through CoinEx could be significantly higher. Iran's broader crypto economy has grown sharply in recent years: TRM Labs and Chainalysis estimate total Iranian crypto transaction volumes reached between $8 billion and $10 billion in 2025, as both state actors and ordinary citizens turned to digital assets to access hard currency and sidestep a crippled traditional financial system.
The CoinEx case illustrates a wider pattern that US regulators are working to address, shifting enforcement focus from individual wallets to the crypto infrastructure that sanctioned actors rely on to move money across borders.
