FinCEN severs MEXC Global from U.S. banks

UPDATED 04:52 UTC, 7 Nov: MEXC said in a statement that it is reviewing the FinCEN order with its legal and compliance team, that the platform is operating normally and user assets are secure, and that it has started an independent review of its anti-money-laundering and sanctions controls, according to TechFlow and The Defiant, which reported that withdrawals continue. MEXC said it plans to engage with FinCEN and other regulators. The order still takes effect 30 days after Federal Register publication.

At a glance

The U.S. Treasury said FinCEN issued an order under section 9714(a) of the Combating Russian Money Laundering Act that prohibits U.S. financial institutions from any funds transfer to or from MEXC Global.
Treasury alleges the convertible virtual currency exchanger facilitated at least $16 billion in illicit transactions between May 2021 and May 2026. The order is effective 30 days after publication in the Federal Register.

FinCEN published the order PDF alongside the release, and its Special Measures table now lists MEXC Global with a final-measure date of 6 Nov 2026. The action sits inside Operation Economic Outcast, the same Friday package that also targeted Canadian money-services businesses (a separate Treasury release).

What Treasury says MEXC did

As of September 2026, Treasury describes MEXC Global as processing more than $1 billion in daily transactions with about $5 billion in reserves, and as one of the world’s top-20 convertible virtual currency exchangers, with trading in more than 50 currencies and access to more than 3,000 tokens.

The release says the platform’s written AML and KYC policies — including bans on Iran and North Korea — did not stop “severe deficiencies” that let prohibited counterparties through. On Russia, Treasury cites nearly $1.5 billion linked to sanctions evasion, including $232 million in direct deals with U.S.-, EU- and UK-sanctioned entities, and says MEXC was still processing with OFAC-sanctioned Garantex and its successor Grinex as recently as June 2026. It also cites at least $26 million tied to the OFAC-sanctioned A7 network and almost $200 million connected to the A7A5 stablecoin.

On Iran, Treasury says MEXC sent or received about $1 billion in direct transactions with more than 40 identified Iranian crypto exchangers between May 2021 and May 2026, and facilitated about $22 million for the Central Bank of Iran and the Islamic Revolutionary Guard Corps and its Qods Force. Those are allegations in an enforcement release, not findings of a court.

Treasury Secretary Scott Bessent, quoted in the release: “Financial institutions cannot have it both ways: Either you support the Iranian regime, or you have access to the U.S. financial system.”

What the order does — and does not do

U.S. banks and other covered financial institutions may not process funds transfers involving MEXC Global once the order is effective. Violations can draw civil or criminal penalties. Treasury says the order does not rewrite Bank Secrecy Act duties (including SARs) or OFAC sanctions rules.

It also does not, by itself, delist MEXC from every foreign venue or freeze every MEXC wallet on-chain. The practical U.S. effect is the banking rails: dollar wires, correspondent banking and other transmittals that touch a U.S. financial institution.

This enforcement track is separate from market-structure rulemaking such as the SEC crypto broker-dealer draft now at OIRA, and from firm-level AML settlements such as Block’s DOJ AML deferred-prosecution disclosure.

What happens next

Watch the Federal Register for the publication that starts the 30-day clock, any FinCEN FAQ or interpretive note for banks, and any MEXC public response. Until publication, the confirmed facts are the order’s existence, its statutory hook, the effective-date formula, and the figures Treasury put on the record.
