Tether Freezes $550M in Iran-Linked USDT Amid Growing Sanctions Campaign

Tether has been cooperating with U.S. authorities to freeze assets linked to Iran's Central Bank and sanctions networks.

In 2026, Tether helped freeze nearly $550 million in USDT as part of a broader campaign against financial networks that support Iran.

The company worked closely with the Office of Foreign Assets Control (OFAC) to identify and freeze over $474 million worth of USDT across multiple wallets and addresses.

Tether CEO Ardoino stated that public blockchains give authorities visibility into transactions, allowing them to take action when law enforcement has credible information.
