FinCEN orders US institutions to cut off crypto exchange MEXC Global

What happened

On 6 November 2026, the US Financial Crimes Enforcement Network (FinCEN) issued an order under section 9714(a) of the Combating Russian Money Laundering Act against MEXC Global. The firm is a convertible virtual currency (CVC) exchanger founded in 2018 and incorporated in the Seychelles. The order finds MEXC Global to be of primary money laundering concern in connection with Russian illicit finance. It prohibits covered financial institutions from engaging in any transmittal of funds from or to MEXC Global. The order takes effect 30 days after publication in the Federal Register, with no cessation date.

FinCEN says that between May 2021 and May 2026, MEXC Global facilitated the movement of USD 16.7 billion connected to Russian illicit finance and other illicit activities. Treasury’s press release uses the figure of at least $16 billion. According to the order, MEXC Global sent or received nearly USD 1.5 billion in exposure linked to Russian sanctions evasion, including USD 232 million in direct transactions with sanctioned entities. After their designations, it directly facilitated about USD 129 million with Garantex and USD 4.1 million with its successor Grinex. It continued to transact with both as recently as June 2026.

The findings extend well beyond Russia. FinCEN assesses that nearly USD 2 billion was connected to identified Iranian actors or known or suspected terrorist groups. That includes over USD 1 billion in direct transactions with more than 40 identified Iranian CVC exchangers, although MEXC Global’s user agreement bars people and entities located in Iran. FinCEN also points to at least USD 1.99 billion linked to illicit cyber actors.

The definition of MEXC Global covers branches, subsidiaries, offices, and successor entities outside the United States. Any located in the United States are excluded.

Why it matters

The measure reaches further than a correspondent account ban. FinCEN explains that restricting those accounts alone would be inadequate, because MEXC Global could still reach US dollars through indirect correspondent relationships. The order defines a transmittal as sending and receiving funds, including CVC.

Receiving is the hard part. FinCEN acknowledges “few, if any, readily available ways” to reject incoming CVC before receipt. It says the order gives institutions flexibility to act with discretion on the facts of a particular transaction, for example where CVC sat for an extended period in an unhosted wallet. The likely effect is that examiners will look for a documented decision on each such receipt.

Firms outside the United States are not directly covered, but FinCEN says the order will put foreign institutions and regulators on notice. FinCEN places MEXC Global among the 20 largest CVC exchangers by trading volume, and assumes a portion of its business is legitimate. Exposure alerts are therefore likely to include many ordinary retail customers.

The order also records earlier warning signs. Regulators in the Seychelles, Hong Kong, and Japan had found MEXC Global operating without a licence, the Hong Kong notice dating from March 2024.

Practitioner angle

• Add the named entities to crypto and fiat screening, including MEXC Global Ltd, MX Global Ltd, MEXC Estonia OÜ, GIDA Technology AG, and MXC Global Ltd.
• Watch the Federal Register for publication, then set your effective date 30 days later.
• Write a procedure for CVC received from MEXC Global after that date, covering who decides, what is recorded, and when funds are held or returned.
• Run a lookback on customer exposure to MEXC Global across the May 2021 to May 2026 period FinCEN reviewed. The order leaves suspicious activity report (SAR) obligations unchanged.
• If you sit outside the United States, ask your US correspondents how they will treat flows with a MEXC Global connection.
• Add regulator warning lists to virtual asset service provider due diligence, so that an unlicensed-operator notice affects the counterparty rating.
