The U.S. Treasury Department's FinCEN has identified MEXC Global as a primary target for money laundering concerns.

On November 6, the U.S. Treasury Department’s FinCEN issued an order designating MEXC Global as a major money laundering target and prohibiting U.S. financial institutions from conducting financial transactions with it. The order took effect on December 10 and has no expiration date. The order states that in the five years leading up to May 2026, MEXC Global circumvented nearly $1.5 billion in Russian sanctions, conducted $232 million in direct transactions with sanctioned entities, had at least $26 million in connections with the A7 network, nearly $200 million in connections with the A7A5 ruble stablecoin, and had approximately $1 billion in transactions with more than 40 Iranian exchanges. As of June 2026, MEXC Global was still conducting transactions with Garantex and its successor, Grinex. FinCEN states that while MEXC Global has banned users from Iran and North Korea, compliance loopholes allow sanctioned entities to still access the system, and the order does not apply to its entities registered in the United States.
