Tether has frozen more than $344 million in USDT following coordination with U.S. authorities, including the Office of Foreign Assets Control (OFAC), targeting two wallet addresses linked to alleged illicit activity. According to AMBCrypto, the action was announced on April 23, 2026, with Tether acting after investigators identified the wallets and flagged them for sanctions evasion, criminal network activity, or other illicit use. The company moved to restrict access and block transactions before the funds could be transferred further, demonstrating how stablecoin issuers have become active participants in financial crime investigations. The latest freeze specifically targets two Tron addresses, potentially linked to Iranian sanctions evasion amid ongoing U.S.-Iran tensions.
CEO Paolo Ardoino stressed that 'USDT is by no means a safe haven for illegal activities,' arguing that the token's traceability and Tether's controls make it a poor tool for criminals. As reported by AMBCrypto, Tether has significantly expanded its enforcement capabilities, working with more than 340 agencies across 65 countries and supporting over 2,300 cases to date. The company has increasingly aligned its wallet-freezing policy with OFAC's Specially Designated Nationals list, blocking addresses connected to sanctioned individuals, terrorism financing, and high-risk jurisdictions. Tether committed to blocking payments that help 'evading sanctions' following reports that Venezuela's state oil company PDVSA used USDT to bypass U.S. sanctions.
U.S. enforcement agencies have leveraged Tether's capabilities in a series of high-profile 'pig butchering' cases, where scammers cultivate relationships with victims before funneling their savings into fake crypto investments. According to AMBCrypto, in February, the U.S. Attorney's Office for the Eastern District of North Carolina announced the seizure of over $61 million in USDT tied to such schemes, with Tether assisting the Department of Justice (DOJ) and Homeland Security Investigations in tracing and transferring the funds. In an earlier civil forfeiture case, the DOJ sought to seize roughly $225 million in USDT routed through exchange OKX, calling it the largest-ever U.S. seizure linked to crypto confidence scams, with authorities acknowledging support from Tether in the operation.
The USDT freeze has generated minimal immediate market reaction, with prediction markets showing only 2.9% probability of stablecoin depegging before 2027. As reported by CryptoBriefing, the freeze may contribute to increased regulatory scrutiny that raises volatility risk for Bitcoin and other cryptocurrencies, though current market liquidity suggests it would take only about $80 in capital to move prices 5 points. The thin order book in prediction markets for Bitcoin dipping to $60,000 in April 2026 indicates traders are waiting for more concrete signals before placing directional bets. Any shift in sentiment would likely show up in order book depth before price moves, with the freeze potentially serving as a precursor to broader enforcement actions touching other cryptocurrencies beyond USDT.
