Binance MEXC Transactions Halted After FinCEN Designates Exchange Primary Money Laundering Concern

Binance announced on November 10, 2026, that it would immediately stop processing transactions involving MEXC Global and approximately 13 affiliated entities. The move follows FinCEN's November 6 designation of MEXC as a financial institution of primary money laundering concern linked to Russian illicit finance.

Binance Implements Immediate Transaction Restrictions

Outgoing transfers to MEXC addresses are now rejected outright. Incoming deposits from MEXC-related wallets undergo compliance review and may result in account restrictions or offboarding for affected users. The policy applies to direct and indirect transfers and covers entities such as MEXC Global Limited, MEXC Estonia OÜ, MEXC Singapore Pte Ltd, GIDA Technology AG and MEXC (Comoros) Ltd.

Binance stated that one listed entity was not explicitly named in the FinCEN order yet still falls under the platform's expanded restrictions. The exchange acted four weeks before the U.S. prohibition takes effect on December 10, 2026. No other major exchanges had announced comparable blocks as of November 11.

Binance's announcement references the need to align internal controls with the forthcoming U.S. regulatory measure. Users with existing MEXC-linked balances face potential holds while reviews proceed.

FinCEN Order Details and Alleged Activity

FinCEN issued the order under Section 9714 of the Combating Russian Money Laundering Act. It prohibits U.S. financial institutions from transmitting funds, including cryptocurrency, to or from MEXC Global or its subsidiaries. The measure takes effect 30 days after Federal Register publication on November 10 and carries no end date.

FinCEN cited more than $16 billion in transactions from May 2021 to May 2026 connected to sanctions evasion, cybercrime and other illicit activity. This total includes nearly $1.5 billion tied to Russian sanctions evasion, with $232 million involving sanctioned entities directly. Additional flows reached Iranian CVC exchangers, Iran's Central Bank and IRGC-linked entities, DPRK facilitators and darknet markets.

MEXC, founded in 2018 and incorporated in Seychelles, processes over $1 billion in daily volume and reported roughly $5 billion in reserves according to FinCEN figures. The agency noted severe deficiencies in AML controls despite the platform's public prohibition on sanctioned-jurisdiction users. MEXC has initiated an independent AML and sanctions review and established communication with FinCEN through U.S. counsel.

Industry Context and Next Steps

The FinCEN designation marks the first use of this authority against a cryptocurrency exchange. MEXC reported that deposits, withdrawals and trading remain operational on its platform, with user assets unaffected. Elliptic restored the exchange to standard categorization following the announcement.

Enforcement begins December 10, 2026. MEXC continues engagement with FinCEN, and further regulatory actions or compliance adjustments remain possible. Other platforms may conduct their own reviews of exposure to designated entities in the coming weeks.
