- FinCEN issued the order under Section 9714 of the Combating Russian Money Laundering Act, barring domestic financial institutions from transacting with or transferring crypto to MEXC.

U.S. Treasury Moves to Cut Off MEXC Over $16 Billion in Illicit Activity
The United States Department of the Treasury has initiated sweeping regulatory action to cut off prominent cryptocurrency exchange MEXC from the American financial system. Federal authorities allege that the platform processed at least $16 billion linked to sanctions evasion, cybercrime, and other illicit financial operations involving Iran, North Korea, and Russia.
The punitive measure was issued on Friday by the Treasury’s Financial Crimes Enforcement Network (FinCEN) pursuant to Section 9714 of the Combating Russian Money Laundering Act. Once the order formally takes effect, U.S. financial institutions will be strictly prohibited from transmitting funds to or receiving funds from MEXC, an enforcement barrier that explicitly covers both fiat transactions and cryptocurrency transfers.
Legal Authority and Enforcement Scope
The Treasury unveiled the action as part of Operation Economic Outcast, an enforcement initiative introduced in August designed to systematically sever Iran’s access to the international financial architecture. However, because Section 9714 authority is statutorily restricted to foreign entities linked to illicit Russian financing, FinCEN’s formal order relies on MEXC’s alleged involvement with Russian illicit financial flows.
By targeting MEXC, federal regulators have significantly escalated their enforcement benchmarks under the anti-money laundering provision. Earlier actions under Section 9714 targeted much smaller cryptocurrency entities, including Bitzlato in 2023 and PM2BTC in 2024. In contrast, MEXC operates on a major global scale. As of September, Treasury figures positioned MEXC among the world’s 20 largest digital asset trading platforms, maintaining approximately $5 billion in reserves and handling more than $1 billion in daily trading volume.
Why This Matters
This action marks a decisive escalation in U.S. efforts to target high-volume offshore cryptocurrency exchanges that facilitate cross-border sanctions evasion and sovereign cybercrime. By invoking Section 9714 against a top-20 global exchange with billions of dollars in reserves, the U.S. government signals that major liquidity hubs can no longer operate outside international compliance norms without facing total isolation from U.S. financial rails, banks, and crypto liquidity conduits.
Frequently Asked Questions
What specific restrictions does the FinCEN order place on MEXC?
Once enacted, the order under Section 9714 requires all U.S. financial institutions to halt processing transactions to or from MEXC. This restriction encompasses traditional fiat transactions as well as cryptocurrency deposits and withdrawals routed through U.S. financial systems.
Why did the Treasury use Russian anti-money laundering authorities if the move falls under an Iran-focused operation?
Although the enforcement action was announced as part of Operation Economic Outcast—a campaign targeted at curbing Iranian illicit finance—Section 9714 of the Combating Russian Money Laundering Act specifically governs foreign institutions linked to Russian illicit activity. As a result, the regulatory order is formally anchored to MEXC’s alleged Russian financial transactions.
How large is MEXC compared to previous platforms targeted under the same law?
MEXC is substantially larger than prior targets like Bitzlato and PM2BTC. According to the U.S. Treasury, MEXC ranks among the top 20 crypto exchanges globally as of September, holding approximately $5 billion in reserves and handling upwards of $1 billion in trading volume on a daily basis.
