Yes, the U.S. Treasury acted against MEXC Global on Nov 6, 2026.

FinCEN, as part of Operation Economic Outcast, issued an order designating MEXC Global of primary money laundering concern and severing its access to the U.S. financial system. U.S. financial institutions will be prohibited from any transmittal of funds to or from MEXC Global, with civil or criminal penalties for violations. The order is effective 30 days after publication in the Federal Register.

Treasury says between May 2021 and May 2026 MEXC moved at least $16B connected to sanctions evasion, cybercrime and other illicit activity, including nearly $1.5B linked to Russian sanctions evasion, including $232M in direct transactions with U.S., EU and UK sanctioned entities, transactions with Garantex and successor Grinex as recently as June 2026, at least $26M benefitting the OFAC-sanctioned A7 network and almost $200M connected to the A7A5 stablecoin. It also cites about $1B in direct transactions with 40+ Iranian exchangers and about $22M for the sanctioned Central Bank of Iran and IRGC and its Qods Force, plus Iranian and North Korean sanctions evasion, ransomware, scams and darknet activity, enabled by severe AML deficiencies.

This is a FinCEN Section 9714 cut-off from U.S. banking, not an OFAC SDN listing of MEXC itself, but the practical effect flagged in Telegram, including markettwits, DeCenter and WatcherGuru via Rickler, is correct: MEXC cannot legally use the U.S. financial ecosystem.

No Treasury notice orders a customer withdrawal freeze, and no halt has been confirmed. Given the U.S. ban, de-risking by banks and partners, and MEXC's recent Russia restrictions, reducing exposure is prudent. Withdraw via normal channels to your own account. Do not follow advice to route through privacy bridges to evade AML controls, that creates further legal and freeze risk.
