FinCEN Cuts MEXC Off From the US Financial System: What the Order Does

In short: FinCEN has ordered every US financial institution it covers to stop moving money to or from the crypto exchange MEXC Global, including crypto transfers. The order rests on a finding that MEXC is of primary money laundering concern in connection with Russian illicit finance. It alleges $16.7 billion in flows tied to sanctions evasion, Iran, North Korea, terrorist groups and cybercrime.

What FinCEN did

The Financial Crimes Enforcement Network posted the action on 6 November 2026, as part of Treasury's Operation Economic Outcast. Treasury's press release says the order "prevents U.S. financial institutions from processing funds transfers involving MEXC Global."

The order itself finds that MEXC Global "is a financial institution operating outside of the United States of primary money laundering concern in connection with Russian illicit finance." It is signed by Jimmy L. Kirby, FinCEN's Deputy Director.

The authority it used

FinCEN did not act under section 311 of the USA PATRIOT Act alone. It used section 9714(a) of the Combating Russian Money Laundering Act, as amended by the National Defense Authorization Act for Fiscal Year 2022. Section 9714 sits in a note to the section 311 statute and adds a power section 311 lacks: a special measure "prohibiting, or imposing conditions upon, certain transmittals of funds."

The difference matters. A section 311 measure on correspondent accounts stops a foreign institution banking through US accounts. The order says a measure limited to those accounts "would be similarly inadequate" here. A ban on transmittals reaches the transfers themselves, crypto included.

This is not an OFAC sanctions designation. Treasury says the order "does not modify existing obligations under the Bank Secrecy Act or sanctions administered by OFAC."

What the order requires

The operative rule is one sentence: "A covered financial institution is prohibited from engaging in any transmittal of funds from or to MEXC Global." The order's key terms:

Crypto creates a practical problem the order acknowledges. FinCEN notes "technological limitations" that may stop institutions from declining crypto transfers sent from addresses outside their control, and says it elected to provide for the rejection of certain incoming CVC transfers. A crypto transfer, like an instant payment, lands without the recipient's consent and cannot simply be refused at the door.

When it takes effect

The order's terms take effect 30 days after publication in the Federal Register, "with no cessation date." The Federal Register's public inspection copy lists it as FR Doc. 2026-22962, scheduled for publication on 10 November 2026. FinCEN chose an order rather than a rulemaking, citing "the imminent threats posed by the illicit actors" whose transactions MEXC facilitates.

What FinCEN alleges

FinCEN's headline figure in the order is $16.7 billion "in funds connected to Russian illicit finance and other illicit activities, including sanctions evasion and cybercrime," between May 2021 and May 2026. Treasury's release rounds this to "at least $16 billion." The order breaks it down by counterparty, based on FinCEN's analysis of blockchain data:

The periods differ by row, so the rows do not sum to the headline. These are FinCEN's findings in an administrative order, not findings of a court.

The order describes MEXC as a crypto exchanger founded in 2018, incorporated in the Seychelles without a virtual asset service provider licence, and operating in over 170 countries. As of June 2026, it says, MEXC processed more than $1 billion a day and held about $5 billion in reserve assets. Before issuing the order, FinCEN consulted the Justice and State Departments and the federal banking and markets regulators; none objected.

MEXC's response

MEXC said in a statement, reported by TechFlow, that it was reviewing the order with its legal and compliance team, that operations were proceeding normally and user assets remained secure, and that it had begun an independent review of its anti-money laundering and sanctions controls.

The precedent

FinCEN's first order under section 9714 targeted the crypto exchange Bitzlato in January 2023, also prohibiting certain transmittals of funds. The MEXC order applies the same tool to a much larger venue.

What it means for compliance teams

The duty falls on US financial institutions, not on MEXC's customers abroad. In practice, the work is screening: identifying wallet addresses and counterparties linked to MEXC's named entities, and stopping transfers to or from them once the order is in force. Incoming crypto is the hard case, and FinCEN's reserved power to set conditions is where any operational guidance will come from. On our reading, the order contains no asset-freeze provision: it restricts what US institutions may transfer, rather than blocking property.
