Treasury Cuts Off MEXC Over $16 Billion in Alleged Illicit Flows

FinCEN barred US financial institutions from moving funds to or from MEXC Global, citing $16 billion in illicit flows from May 2021 to May 2026.

Woman in glasses raising a finger in a warning gesture

The US Treasury's Financial Crimes Enforcement Network (FinCEN) on Friday, 6 November 2026, ordered US financial institutions to stop processing any funds transfer to or from MEXC Global, one of the world's 20 largest crypto exchanges by volume. FinCEN alleges that MEXC moved at least $16 billion tied to sanctions evasion, cybercrime and other illicit activity between May 2021 and May 2026. The ban takes effect 30 days after the order appears in the Federal Register. As of Friday evening, it had not appeared there.

What the FinCEN order does

The order is a funds-transmittal ban, not a sanctions listing. FinCEN issued it under section 9714(a) of the Combating Russian Money Laundering Act, after finding MEXC a "primary money laundering concern" in connection with Russian illicit finance. FinCEN used the same provision against the Russia-linked exchange Bitzlato in January 2023. The order was signed by FinCEN Deputy Director Jimmy L. Kirby and frames the action as part of Treasury's Operation Economic Outcast.

Once the 30-day window closes, US banks, money transmitters and other covered institutions cannot send or receive dollars or crypto to or from MEXC. Willful violations carry civil or criminal penalties. The order leaves Bank Secrecy Act reporting and OFAC rules unchanged, and it sets no end date.

The ban reaches beyond one company. The order names these MEXC entities and their successors:

  • MEXC Global Ltd and MX Global Ltd, incorporated in Seychelles
  • MEXC Estonia OÜ in Estonia
  • GIDA Technology AG in Switzerland
  • MXC Global Ltd in the United Kingdom

The $16 billion in Treasury's allegations

Treasury's press release uses $16 billion. The 24-page order itself puts the figure at $16.7 billion. Treasury breaks out these components of the total, with its own rounding:

FlowAmountPeriod
Russian sanctions evasionnearly $1.5 billionMay 2021 to May 2026
Direct transactions with US-, EU- and UK-sanctioned entities$232 millionSame
A7A5 ruble-backed stablecoinalmost $200 millionSame
OFAC-sanctioned A7 networkat least $26 millionSame
Direct transfers with 40+ Iranian exchanges$1 billionSame
Central Bank of Iran, IRGC and Qods Force$22 millionSame

The named items add up to less than $3 billion. Treasury attributes the remainder to cybercrime, ransomware and scam payments, and darknet market activity, with no further breakdown. North Korea appears in the order as a jurisdiction MEXC served despite its own ban on DPRK users. No dollar figure is given.

One detail weighs more than the totals. FinCEN says MEXC kept transacting with Garantex and its successor Grinex as late as June 2026. OFAC designated Garantex in April 2022. The Crypto Times, citing the order, puts those flows at $129 million with Garantex and $4.1 million with Grinex. In our view, four years of exposure to a listed exchange is hard to explain as a screening gap.

Treasury Secretary Scott Bessent said financial institutions "cannot have it both ways." FinCEN described MEXC's anti-money-laundering controls as having "severe deficiencies," despite the exchange's published policies barring users from Iran and North Korea.

How MEXC responded

MEXC posted marketing content on X through Friday afternoon. It acknowledged the order on 7 November. The exchange said it is reviewing the order with its legal and compliance teams, that it is "operating normally" and that user assets remain secure. MEXC also said it has started an independent review of its AML and sanctions controls and intends to engage with FinCEN and other regulators.

CEO Vugar Usi said deposits and withdrawals were running despite higher withdrawal volumes. The exchange published no withdrawal figures. By Treasury's count, MEXC processed more than $1 billion a day and held $5 billion in reserves as of September 2026. DefiLlama data cited in coverage put its total assets at $4.48 billion on 6 November.

What changes for users outside the US

For US residents, little changes on paper. MEXC already lists the United States as a prohibited jurisdiction in its terms. The order targets the infrastructure that serves the exchange: dollar rails, banking partners and US-regulated counterparties.

For users in Canada, the UK and Australia, the order creates no direct obligation. The indirect effects are harder to read. The questions that remain open as of 8 November:

  • Whether US-based payment processors, card networks and liquidity providers end their MEXC relationships before the deadline.
  • Whether MEXC contests the finding, seeks an exemption or reroutes liquidity through non-US partners.
  • Whether regulators outside the US follow, given that the UK's FCA has listed MEXC Global as unauthorized since March 2024 and Seychelles' FSA took action against MX Global Ltd in May 2026.

This is a softer instrument than the 2022 Garantex designation. Wallets on MEXC are not frozen, and non-US trading continues. Still, the order has no end date, and FinCEN chose an order over a slower rulemaking, citing imminent threats. In our assessment, that choice signals that Treasury sees no room for a negotiated fix within 30 days.
