FinCEN cuts MEXC off from U.S. finance over $16 billion in alleged illicit flows
A Section 9714 order bars U.S. financial institutions from moving funds, including crypto, to or from MEXC Global. It is the largest exchange ever hit under the Russia-focused law.

TL;DR
- On Nov. 6, 2026, FinCEN issued an order under Section 9714(a) of the Combating Russian Money Laundering Act that prohibits U.S. financial institutions from any transmittal of funds to or from MEXC Global, the U.S. Treasury said.
- Treasury alleges MEXC facilitated at least $16 billion tied to sanctions evasion, cybercrime and other illicit activity between May 2021 and May 2026, including nearly $1.5 billion linked to Russian sanctions evasion.
- The order takes effect 30 days after publication in the Federal Register; CoinDesk reports MEXC is the largest crypto exchange targeted under Section 9714, after far smaller Bitzlato (2023) and PM2BTC (2024).
- MEXC said it is reviewing the order, continues to operate normally and has launched an independent review of its AML and sanctions controls, according to CoinDesk.
Washington just pulled one of the world's 20 largest crypto exchanges off the U.S. banking grid. On Nov. 6, 2026, the Treasury's Financial Crimes Enforcement Network (FinCEN) issued an order that prohibits U.S. financial institutions from engaging in any transmittal of funds from or to MEXC Global, according to the U.S. Treasury.
Treasury alleges MEXC facilitated at least $16 billion in illicit transactions connected to Iranian, North Korean and Russian sanctions evasion and cybercrime between May 2021 and May 2026.
What the order does
The order rests on Section 9714(a) of the Combating Russian Money Laundering Act. Once in force, it bars U.S. financial institutions from sending funds to or receiving funds from MEXC, including crypto transfers, CoinDesk reported. Violations may result in civil or criminal penalties, Treasury said. The order takes effect 30 days after publication in the Federal Register.
Treasury announced the step under Operation Economic Outcast, its campaign against Iran's access to global finance. But Section 9714 can only be used against foreign institutions tied to Russian illicit finance, so the order formally rests on MEXC's alleged Russian dealings, CoinDesk noted.
The allegations
- Nearly $1.5 billion linked to Russian sanctions evasion, including $232 million in direct transactions with U.S.-, EU- and UK-sanctioned entities (Treasury).
- Transactions with sanctioned Russian exchange Garantex and its successor Grinex as recently as June 2026 (Treasury).
- Almost $200 million connected to the A7A5 stablecoin and at least $26 million benefitting the sanctioned A7 network (Treasury).
- About $1 billion in direct transactions with more than 40 Iranian crypto exchangers, and about $22 million for the Central Bank of Iran and the IRGC and its Qods Force (Treasury).
Treasury says MEXC, founded in 2018, processed more than $1 billion in daily transactions and held about $5 billion in reserves as of September 2026, offering access to more than 3,000 cryptocurrencies and tokenized assets.
"Financial institutions cannot have it both ways: Either you support the Iranian regime, or you have access to the U.S. financial system," Treasury Secretary Scott Bessent said in the release.
MEXC's response
MEXC, which announced in October 2026 that it would stop serving users in Russia and Belarus, said it is reviewing the order, continues to operate normally and has launched an independent review of its anti-money-laundering and sanctions controls, CoinDesk reported. CoinDesk called MEXC the largest crypto exchange targeted under Section 9714; earlier targets Bitzlato (2023) and PM2BTC (2024) were far smaller.
What it means for Web3 teams – Analysis
This is not a fine. It is a plumbing cut. Any project that relies on MEXC for listings, market making or treasury liquidity now faces a counterparty that U.S. banks, payment firms and regulated custodians must stop touching once the order takes effect. Map your exposure before the Federal Register clock runs out: listing agreements, MM loans, deposit addresses used by U.S. partners. Offshore volume is not the same as offshore immunity. Not investment advice.
