The Treasury Department on Nov. 6 ordered U.S. financial institutions to stop moving money to or from MEXC Global, the crypto exchange it says handled at least $16 billion tied to sanctions evasion, cybercrime and other illicit activity. The action, announced as part of what Treasury calls Operation Economic Outcast, effectively cuts the exchange off from the U.S. financial system. It takes effect 30 days after the order is published in the Federal Register.
What exactly did Treasury order?
The order comes from the Financial Crimes Enforcement Network, known as FinCEN, a Treasury bureau. FinCEN issued it under section 9714(a) of the Combating Russian Money Laundering Act, and it is titled “Imposition of Special Measure Prohibiting the Transmittal of Funds Involving MEXC Global.” Its core rule reads: “A covered financial institution is prohibited from engaging in any transmittal of funds from or to MEXC Global.”
Transmittals of funds include sending and receiving money, including convertible virtual currency, the order says. Willful violations can bring civil or criminal penalties for the institutions and for their officers, directors, employees and agents. The order does not change existing Bank Secrecy Act duties, such as filing suspicious activity reports, or sanctions obligations enforced by the Treasury’s Office of Foreign Assets Control.
For anyone who holds crypto, the question is whether any of their money touches this exchange, because banks and payment firms must stop handling transfers once the order is in force. Neither Treasury’s release nor the order says anything about what happens to customer balances held on MEXC. The order’s reach is on the U.S. side of the transfer, and it excludes U.S.-located affiliates, branches and offices of the exchange.

Where does the $16 billion figure come from?
Treasury says the money moved between May 2021 and May 2026. About $1.5 billion was linked to Russian sanctions evasion, including $232 million in direct transactions with entities sanctioned by the United States, the European Union or the United Kingdom. Treasury also says MEXC dealt with the sanctioned exchange Garantex and its successor Grinex as recently as June 2026.
The release adds that about $1 billion went in direct transactions with more than 40 identified Iranian crypto exchangers, and about $22 million benefited the Central Bank of Iran and the IRGC-Qods Force. The FinCEN order itself puts the Russia-linked and other illicit total at $16.7 billion. Its finding is that MEXC is of primary money laundering concern in connection with Russian illicit finance, which is the legal basis for the order. Treasury describes the Iran, North Korea and cybercrime links as further evidence, but the Russia finding is what the order rests on.
Who is MEXC, and who runs it?
Treasury says MEXC Global was founded in 2018 and, as of September 2026, processed more than $1 billion in daily transactions and held about $5 billion in reserves. It describes the exchange as one of the 20 largest crypto exchangers in the world, offering trading in more than 50 currencies and access to more than 3,000 cryptocurrencies and tokenized assets. The release does not say where the company is headquartered.
The order names the entities it covers: MEXC Global Ltd, also known as MX Global Ltd, in Seychelles; MEXC Estonia OĂś in Estonia; GIDA Technology AG in Switzerland; and MXC Global Ltd in the United Kingdom. It also covers the formerly Singapore-registered MEXC Global Foundation Ltd and MEXC Singapore Pte Ltd, plus any successor entities. The order is signed by FinCEN Deputy Director Jimmy L. Kirby.
What did Treasury say about compliance and Iran?
MEXC says it has anti-money-laundering and customer verification policies and bars users in certain jurisdictions, including Iran and North Korea. Treasury says weaknesses in those controls allowed transactions involving those places anyway. Treasury Secretary Scott Bessent said “financial institutions cannot have it both ways,” and that Treasury “will continue to sever the Iranian regime’s economic lifelines.”
The release also points to FinCEN’s whistleblower program. People who report sanctions violations, including those that involve Iranian proxies and facilitators, may be eligible for awards if their information leads to an enforcement action with penalties above $1 million.
What happens before the cutoff takes effect?
The order as released is a pre-publication version with no Federal Register citation, and FinCEN says the official text will appear at federalregister.gov and treasury.gov. The 30-day clock starts when that publication happens, so the exact start date depends on it. The order also reserves FinCEN’s authority to set conditions on some transmittals and to grant exemptions.
It lets institutions reject certain crypto transfers received from or originating at MEXC, and gives them some discretion where funds cannot be returned, such as when they sit in an unhosted wallet. Covered financial institutions that handle crypto transfers will need to screen for the exchange once the order is in force, and the order spells out that the prohibition applies to transfers both from and to MEXC Global.
Do your bank logins hold up when crypto money moves?
The MEXC order is aimed at an exchange, not at customers. Still, anyone who sends money from a bank account to a crypto platform is relying on that bank login staying private, and a stolen login lets a thief send the money out the same way.
