FinCEN Orders U.S. Institutions to Halt Fund Transfers Involving MEXC Global

On 6 November 2026 the U.S. Department of the Treasury's Financial Crimes Enforcement Network (FinCEN) issued an order finding that MEXC Global — a Seychelles-incorporated convertible virtual currency exchanger among the world's 20 largest by trading volume — is a financial institution operating outside the United States of primary money laundering concern in connection with Russian illicit finance. The order prohibits covered U.S. financial institutions from engaging in any transmittal of funds from or to MEXC Global.

The instrument is titled "Imposition of Special Measure Prohibiting the Transmittal of Funds Involving MEXC Global" and rests on section 9714(a) of the Combating Russian Money Laundering Act, as amended. Treasury's same-day press release states that the order takes effect 30 days after publication in the Federal Register. The pre-publication PDF on FinCEN's site uses the same 30-day-after-publication formula and carries no cessation date. FinCEN's public special-measures table already lists a MEXC Global final rule dated 11/06/2026.

What the Order Requires of Covered Institutions

Under the order, a covered financial institution — defined by cross-reference to "financial institution" in 31 CFR 1010.100(t) — is prohibited from engaging in any transmittal of funds from or to MEXC Global. "Transmittals of funds" expressly include convertible virtual currency (CVC). The defined target covers MEXC Global's branches, subsidiaries and offices operating as a financial institution outside the United States, and any successor entities; U.S.-located affiliates, subsidiaries, branches and offices are expressly excluded from the definition and therefore outside the order's scope.

The order names illustrative affiliated entities including MEXC Global Ltd / MX Global Ltd (Seychelles), MEXC Estonia OÜ (Estonia), GIDA Technology AG (Switzerland) and MXC Global Ltd (United Kingdom), plus formerly Singapore-registered entities. Violations may attract civil or criminal penalties under 31 U.S.C. 5321 and 5322 for willful non-compliance. The order does not modify existing Bank Secrecy Act obligations, including Suspicious Activity Report filing, or OFAC sanctions programmes. FinCEN reserves authority to impose conditions or grant exemptions.

Treasury's press release frames the practical effect as cutting off MEXC Global's access to the U.S. financial system: U.S. financial institutions may not process funds transfers involving the exchanger once the order is in force. As of the 6 November announcement the Federal Register publication date — and therefore the exact calendar force date — had not yet been set in the pre-publication PDF.

Why FinCEN Found Primary Money Laundering Concern

FinCEN's finding rests on public and non-public information that, between May 2021 and May 2026, MEXC Global facilitated about USD 16.7 billion in funds connected to Russian illicit finance and other illicit activity, including sanctions evasion and cybercrime. Within that total, the order cites nearly USD 1.5 billion linked to Russian sanctions evasion, including USD 232 million in direct transactions with entities sanctioned by the United States, the European Union and/or the United Kingdom.

Concrete examples in the order include continued processing of transactions with OFAC-sanctioned Garantex and its successor Grinex as recently as June 2026 — more than four years after Garantex's April 2022 designation — about USD 129 million with Garantex and USD 4.1 million with Grinex after those designations. The order also cites exposure to the Russia-based, OFAC-sanctioned A7 sanctions-evasion network and almost USD 200 million connected to the A7A5 stablecoin. Parallel findings cover Iranian and DPRK-linked flows: about USD 1 billion in direct transactions with more than 40 identified Iranian CVC exchangers, and about USD 22 million involving the Central Bank of Iran and the Islamic Revolutionary Guard Corps and its Qods Force.

FinCEN assesses that MEXC Global's published AML/CFT and customer-identification policies have been insufficient in practice, including facilitation of transactions involving jurisdictions the platform's own user agreement prohibits. The order also notes prior licensing enforcement or public warnings against MEXC Global in Seychelles, Hong Kong and Japan. As of June 2026 the exchanger processed more than USD 1 billion in daily transactions and held about USD 5 billion in reserves, with trading in more than 50 currencies and access to more than 3,000 CVCs and tokenized assets.

Companion OFAC Designations and What Comes Next

The FinCEN order was announced as part of Operation Economic Outcast. On the same day OFAC designated eight Canada-based money services businesses under Executive Order 13902 for operating in Iran's digital asset sector: Diverse Trade Inc (Million Exchange), 1380079 BC Limited and Top PC Technician Inc (Amin Exchange), NIA Nations Currency Ltd, 2397639 Ontario Ltd (Farah Exchange), CCC Inc, B Galaxy Inc (Cryptoyal), and Darvish Exchange. Treasury says those firms facilitate rial and other-currency exchanges into digital assets for Iran-linked flows, including activity involving IRGC-associated addresses and previously sanctioned Iranian exchanges.

Immediate addressees of the FinCEN measure are U.S. covered financial institutions that must stop fund and CVC transmittals involving MEXC Global once the 30-day post-publication clock runs. Counterparties, banks that clear fiat for crypto platforms, and any firm that routes USD rails to or from MEXC Global need to map exposure before the force date. Existing BSA and OFAC duties continue unchanged. Watchpoints are Federal Register publication of the order (which sets the 30-day force date), any FinCEN exemption or condition notices, and further SDN or special-measure actions under the same operation.
