This isn’t the kind of “naming” where OFAC puts you on a sanctions list. It’s a more direct move: U.S. financial institutions are barred from processing payments for you.
On November 6, the U.S. Treasury Department’s FinCEN, under the banner of “Operation Economic Outcast,” issued an order against MEXC Global under Section 9714(a) of the (Combating Russian Money Laundering Act): U.S. financial institutions are prohibited from processing any funds transfers to or from the platform, including transfers involving convertible virtual currency. The order takes effect 30 days after publication in the Federal Register and has no expiration date.
The official allegations involve substantial sums: from May 2021 to May 2026, at least $16 billion was linked to sanctions evasion, cybercrime, and other activities. Of that, about $1.5 billion involved Russian entities, including $232 million in direct dealings with sanctioned parties; roughly $1 billion involved transactions with more than 40 Iranian crypto exchange points. The allegations also name the IRGC’s Quds Force, among others. More strikingly, OFAC flagged Garantex back in 2022, yet MEXC was still dealing with it and its successor platform Grinex as of June 2026.
As of September 2026, according to official figures, MEXC handles over $1 billion in daily trading and holds about $5 billion in reserves, ranking among the top 20 globally. FinCEN said its AML controls had “serious deficiencies,” allowing funds from prohibited jurisdictions to flow through anyway.
To be clear: this does not place the exchange itself on the OFAC list; it cuts off its access to U.S. banks. Violations may incur civil or criminal penalties; this does not change BSA reporting or OFAC obligations.
MEXC says operations are normal and withdrawals are continuing, and that it has launched an independent review of its anti-money laundering and sanctions compliance. Whether users’ assets are affected will depend on how banks act after the notice is published in the Federal Register, and whether MEXC can address its compliance gaps.
A telling pattern: an exchange says it bars Iran and North Korea, yet its transaction flows match up with sanctioned entities. Regulators are increasingly unwilling to accept stories about rules “on the wall” but enforcement elsewhere. This is not investment advice.
