Binance Blocks MEXC Transfers After FinCEN’s $16 Billion Money Laundering Allegations
Binance has introduced immediate restrictions on transactions involving cryptocurrency exchange MEXC and its affiliated entities following a major enforcement action by the US Treasury Department. The exchange announced on November 10 that users can no longer send funds to, receive funds from or otherwise conduct transactions involving the designated entities through Binance.
The restrictions cover a broad list of businesses, including MEXC Global Limited, MEXC Estonia OÜ, GIDA Technology AG, MEXC Singapore Pte Ltd, MXC Global Ltd, MEXC Global Foundation Ltd and MEXC (Comoros) Ltd. Binance also included MEXC affiliates, related entities and several other corporate names associated with the exchange.
Under the new measures, withdrawal requests from Binance accounts to the listed entities will be rejected. Deposits originating from those businesses will be temporarily withheld and subjected to compliance reviews. Binance warned that affected users could face account restrictions while investigations are ongoing, with further action potentially including termination of services under its Terms of Use.
The announcement also extends beyond direct transfers. Binance specifically warned customers against indirect transactions involving MEXC through its platform. This means users should not assume that routing funds through another wallet or intermediary will avoid the restrictions if the transaction is ultimately connected to a listed entity.
The decision follows FinCEN’s November 6 announcement identifying MEXC Global as a financial institution of primary money laundering concern. The US agency said the exchange had facilitated at least $16 billion in transactions connected to illicit finance between May 2021 and May 2026, including sanctions evasion, cybercrime and transactions involving sanctioned actors.
Why FinCEN Targeted MEXC
According to the US Treasury, MEXC Global facilitated transactions connected to Russian illicit financial networks, Iranian entities and North Korean financial facilitators. FinCEN also identified activity involving darknet markets and cybercriminals. The agency attributed the exposure partly to weaknesses in the exchange’s anti-money laundering controls and customer identification procedures.
One particularly significant allegation concerns transactions involving Iranian cryptocurrency exchanges. FinCEN said MEXC processed approximately $1 billion in direct transactions with more than 40 identified Iranian crypto exchanges between May 2021 and May 2026. It also identified approximately $22 million in transactions benefiting Iran’s sanctioned central bank and the Islamic Revolutionary Guard Corps and its Qods Force.

FinCEN’s action was issued under Section 9714 of the Combating Russian Money Laundering Act. It prohibits covered financial institutions from processing certain transfers to or from MEXC Global. However, the federal order becomes effective 30 days after publication in the Federal Register. Binance’s decision to introduce its own restrictions immediately is a separate compliance measure that goes beyond simply waiting for that effective date.
MEXC has disputed the implications of the regulatory action. The exchange said its legal and compliance teams were reviewing the order and its sanctions and anti-money laundering controls. It also maintained that its platform remained operational and that user assets were secure. These statements do not resolve the allegations, but they demonstrate that MEXC has not publicly accepted FinCEN’s assessment.
What Binance’s Decision Means for Crypto Users
For customers, the immediate concern is the possibility of having deposits withheld or accounts restricted because of transaction histories involving the listed entities. Binance has not provided a fixed timetable for completing compliance reviews or releasing affected funds. Users who believe their transactions may be impacted should contact Binance through its official support channels rather than attempting to bypass the restrictions.
The decision also highlights the increasing compliance responsibilities facing centralized exchanges. Binance is effectively screening not only the identities of its direct customers but also the counterparties connected to transactions passing through its infrastructure. This reflects a broader shift toward monitoring the origin and destination of funds, particularly when regulators identify exposure to sanctions evasion or other illicit financial activity.

For MEXC, losing access to transaction channels involving one of the industry’s largest exchanges could complicate fund movements for customers who regularly transfer assets between the two platforms. The longer-term consequences will depend on how other exchanges, payment providers and financial institutions respond to FinCEN’s findings.
The development sends a wider message to the cryptocurrency industry: regulatory exposure at one exchange can quickly affect access to other platforms. Binance’s immediate response demonstrates how compliance decisions can reshape the movement of digital assets before a federal prohibition formally takes effect. For crypto users, checking counterparties and understanding exchange restrictions are becoming increasingly important parts of managing digital assets.
