Tether Reports $550 Million in Iran-Linked Freezes Amid Senate Scrutiny

Tether stated it successfully froze approximately $550 million in USDT linked to Iranian sanctions networks throughout 2026. This follows a report from the Senate Permanent Subcommittee on Investigations, which analyzed 846 wallets associated with Iran and regional groups, noting that 84% of these wallets transacted primarily in USDT. Democratic subcommittee staff alleged that delays in blacklisting certain wallets allowed roughly $35 million to move illicitly. Senator Richard Blumenthal has referred these findings to the Treasury and Justice departments to review Tether's compliance with anti-money laundering and sanctions regulations. Tether maintains that its cooperation with authorities led to the freezing of the identified assets.
