FinCEN Bars Transfers to and From MEXC After Identifying $16.7 Billion Linked to Illicit Finance
Key Facts
The U.S. Treasury Department’s Financial Crimes Enforcement Network, or FinCEN, issued an order on November 6, 2026, barring covered financial institutions from sending funds to or receiving them from MEXC Global. FinCEN said the platform facilitated the movement of $16.7 billion in funds linked to illicit Russian finance and other illicit activity between May 2021 and May 2026. The legal designation rests on the finding that MEXC is a primary money laundering concern in connection with illicit Russian finance. A transfer is defined to include sending and receiving funds, including convertible virtual currency. The order targets covered institutions’ transaction channels and does not call for the trading platform itself to be shut down.
The order prohibits any transfer of funds to or from MEXC at a covered financial institution, but expressly excludes the platform’s branches, subsidiaries and offices located in the United States from the definition of MEXC Global for purposes of the measure. The Treasury Department said violations could result in civil or criminal penalties and that the order does not change existing reporting obligations under the Bank Secrecy Act. The stated legal basis centers on Russian finance, while the order’s findings also include Iranian and North Korean flows and transactions linked to cybercrime. For Russia, FinCEN estimated that the platform’s transactions with direct and indirect exposure linked to sanctions evasion totaled nearly $1.5 billion between May 2021 and May 2026. That included $232 million in direct transactions with entities subject to U.S., European or British sanctions.
FinCEN detailed some flows linked to sanctioned Russian platforms. After Garantex was added to sanctions lists, direct activity with MEXC totaled about $129 million, while activity with Grinex totaled $4.1 million; the network said dealings with both platforms continued through June 2026. It also said MEXC facilitated at least $26 million in transfers for Russia’s sanctioned A7 network and sent or received nearly $200 million linked to the A7A5 stablecoin. The network estimated that the platform transacted directly more than $13 billion with at least four high-risk platforms between May 2018 and July 2026. Between May 2021 and May 2026, its direct transactions with Russian platforms and others said to collect no customer identity verification data totaled about $2.9 billion.
Regarding Iran, FinCEN said more than $1 billion in direct transactions took place between MEXC and more than 40 Iranian virtual currency platforms identified by authorities. It estimated total transactions with Iran exposure at about $1.87 billion, within nearly $2 billion linked to Iranian entities or known or suspected terrorist groups. The findings included about $22 million in transactions linked to Iran’s sanctioned central bank, the Islamic Revolutionary Guard Corps and the Quds Force. The order also cited about $36 million in transactions linked to Hamas’s Izz al-Din al-Qassam Brigades and other Iran-linked groups between May 2021 and May 2026. On North Korea, FinCEN said the platform facilitated the receipt of about $350,000 by U.S.-sanctioned financial facilitator Sim Hyon-sop between June and September 2025.
Alongside sanctions-related flows, FinCEN identified at least $1.99 billion in funds transferred to or from cybercriminal entities through MEXC between May 2021 and May 2026, averaging more than $1 million a day. It said that between January 2022 and July 2024, the platform received more than $37.9 million in suspected ransomware payments, with exposure to more than 125 ransomware variants. The order also identified $8.5 million in transactions linked to Russian dark-web marketplaces between September 2020 and July 2026. Treasury Secretary Scott Bessent said financial institutions "cannot have it both ways: either support the Iranian regime, or retain access to the U.S. financial system." In September 2026, FinCEN held an information-sharing meeting with global financial institutions in support of an "economic exclusion" operation, and Bessent said the department would continue working with the private sector against Iranian financial networks.
MEXC ranked among the world’s top 20 convertible virtual currency platforms by trading volume in June 2026, according to FinCEN estimates. The order said it was then processing transactions worth more than $1 billion a day, with reserves of nearly $5 billion. In response to the order, the company said it was reviewing it in coordination with its legal and compliance teams, continuing normal operations and beginning an independent review of its anti-money laundering and sanctions controls. It added that "MEXC is operating normally." Chief Executive Vugar Usi said withdrawal volumes increased after the order was issued, but operations remained orderly. The order is scheduled to be published in the Federal Register on November 10, 2026, and states that it will take effect 30 days after publication, with no expiration date.
The move falls under authority FinCEN has previously used to cut off transfers linked to virtual currency platforms. In an action against Bitzlato, the network set February 1, 2023, as the date covered institutions would begin prohibiting transfers. The MEXC order sets a similar effective period, calculated from publication, and is due to take effect 30 days after publication in the Federal Register. The order does not set an expiration date for the restrictions. The ban’s start date therefore depends on the official publication date and the specified waiting period.
