Overview
- Treasury Secretary Scott Bessent said Friday that U.S. authorities have seized roughly $1 billion in cryptocurrency tied to Iran as part of a sustained campaign called Operation Economic Fury.
- On‑chain actions independently confirmed include Tether’s freeze of about $344 million in USDT on two Tron addresses and additional Treasury seizures that together approach $500 million, with the larger $1 billion figure appearing to aggregate separate measures rather than a single audited takeaway.
- Blockchain‑forensics firm Chainalysis helped attribute the frozen Tron addresses to Islamic Revolutionary Guard Corps patterns, and Tether’s ability to freeze USDT has become a practical enforcement chokepoint for U.S. sanctions.
- The campaign, launched in March 2025, combines OFAC designations, sanctions on exchanges, coordinated asset freezes of bank accounts and overseas real estate with allied governments, and targeted actions against wallets and crypto infrastructure.
- U.S. officials say the pressure has strained Iran’s finances—citing unpaid security personnel and high inflation—while the use of stablecoins and alternative chains by Iranian actors highlights both how crypto can be used to evade sanctions and how centralized service providers can be used to enforce them.
