The US Treasury Department’s Financial Crimes Enforcement Network issued a final order on November 6, 2026, that will sever major cryptocurrency exchange MEXC Global from the American financial system. Officials alleged the platform facilitated at least $16 billion in illicit transactions between May 2021 and May 2026 linked to sanctions evasion, cybercrime and other prohibited activity involving Iran, North Korea and Russia.

The action forms part of Operation Economic Outcast, a broader campaign aimed at disrupting financial channels that enable the Iranian regime and other sanctioned actors to move funds through digital assets. Unlike a standard Office of Foreign Assets Control designation, the measure relies on Section 9714(a) of the Combating Russian Money Laundering Act. It identifies MEXC as a primary money laundering concern in connection with Russian illicit finance and prohibits covered US financial institutions from processing any funds transfers—including convertible virtual currency—to or from the exchange or its named affiliates.

Details of the Alleged Activity

FinCEN’s findings detail sustained transaction patterns over the five-year period. Roughly $1.5 billion was tied to Russian sanctions evasion, of which about $232 million involved direct transfers with entities already sanctioned by the United States, European Union or United Kingdom. The exchange continued to process trades with the sanctioned Russian platform Garantex and its successor Grinex as recently as June 2026, more than four years after Garantex was first designated.

Iranian-linked flows included approximately $1 billion in direct traffic with more than 40 Iranian cryptocurrency exchanges and about $22 million connected to Iran’s Central Bank and the Islamic Revolutionary Guard Corps’ Qods Force. Additional volumes of nearly $200 million were associated with the A7A5 stablecoin and roughly $26 million with Russia’s sanctioned A7 network. North Korean facilitators and cybercrime-related activity were also cited.

Regulators pointed to severe deficiencies in MEXC’s anti-money-laundering and customer-identification controls despite the platform’s public claims of compliance policies and geographic restrictions. The order covers MEXC Global and affiliates operating outside the United States, including Seychelles-incorporated entities, Estonia’s MEXC Estonia OÜ, Switzerland’s GIDA Technology AG and the United Kingdom’s MXC Global Ltd, along with any successors.

Scope and Timeline of the Restriction

Once published in the Federal Register, the order starts a 30-day clock. After that period, US banks, money transmitters and other covered institutions face civil or criminal penalties for willful violations if they process transfers involving the named entities. The restriction does not rewrite existing Bank Secrecy Act obligations or OFAC rules; it functions specifically as a funds-transmittal ban.

MEXC, founded in 2018 and formerly known as MXC, ranks among the world’s 20 largest centralized crypto venues by trading volume. Treasury data indicated daily turnover exceeding $1 billion and reserves near $5 billion as of mid-to-late 2026, with the platform offering access to more than 3,000 tokens. Independent data placed total assets around $4.48 billion at the time of the announcement. The exchange already lists the United States as a prohibited jurisdiction in its terms of service, so the practical impact centers on remaining dollar-clearing relationships, banking partners and counterparties that still interact with US institutions.

Prior regulatory scrutiny had already appeared in multiple jurisdictions. The UK Financial Conduct Authority added the firm to its warning list in 2024, Hong Kong’s Securities and Futures Commission issued a similar alert the same year, and Seychelles authorities took enforcement action in 2026 for unlicensed virtual-asset operations.

Context Within Broader Enforcement Efforts

The MEXC order arrives amid an intensified focus on crypto infrastructure used for sanctions circumvention. Recent related actions have targeted Russian networks linked to the A7A5 token and Iranian platforms such as Nobitex. The FinCEN tool under the Combating Russian Money Laundering Act has been applied previously to other venues, providing a mechanism to isolate platforms that operate largely outside traditional correspondent banking channels.

As of the order’s issuance, MEXC had not issued a public response. Its main social media channels continued routine marketing activity. Market participants will now monitor Federal Register publication for the exact effective date and any subsequent adjustments by the exchange to its banking relationships, liquidity routes or operational structure outside US rails.
