The U.S. government has frozen nearly $500 million in cryptocurrency assets tied to Iranian financial networks, one of the largest digital asset seizures targeting a sanctioned nation. Treasury Secretary Scott Bessent announced the milestone on April 29, calling it a critical escalation in Washington’s economic pressure campaign.
The seizures fall under “Operation Economic Fury,” a Trump administration initiative launched in March 2025 that targets Iran’s use of crypto channels to evade sanctions.
Tether froze more than $344 million in USDT after OFAC sanctioned multiple crypto wallets linked to Iran on April 24. Additional wallet seizures and frozen bank accounts brought the total close to $500 million.
Bessent framed the timing around Iran’s “currency crisis,” noting the sanctions compound severe economic turmoil. Iran faced a major bank collapse and severe currency depreciation in late 2025.
The $344 million freeze underscores that when OFAC comes calling, Tether responds quickly. For Tether, cooperation with U.S. authorities demonstrates regulatory compliance as stablecoin legislation moves through Congress.
The layered enforcement model-OFAC designations, stablecoin issuer compliance, and cross-border exchange sanctions-creates significant legal exposure for any platform interacting with wallets even tangentially connected to sanctioned entities.
