FinCEN order would cut MEXC Global off from U.S. finance over an alleged $16 billion: check your withdrawal route

What the order prohibits

The text is short on this point: "A covered financial institution is prohibited from engaging in any transmittal of funds from or to MEXC Global." FinCEN defines a transmittal as sending and receiving funds, and it includes convertible virtual currency, so stablecoins and bitcoin are covered as well as bank wires. The order has no end date. Institutions that willfully break it, and their officers, may face civil or criminal penalties.

FinCEN used section 9714(a) of the Combating Russian Money Laundering Act, finding MEXC Global to be of "primary money laundering concern" in connection with Russian illicit finance. Treasury's press release announces a FinCEN order and does not announce an OFAC sanctions designation of MEXC itself. It does say existing OFAC and Bank Secrecy Act duties are unchanged.

The definition reaches beyond one company. It names MEXC Global Ltd and MX Global Ltd in Seychelles, MEXC Estonia OÜ, GIDA Technology AG in Switzerland and MXC Global Ltd in the United Kingdom, two former Singapore entities, and any successor. A rebrand or a new company carrying on the business would still fall inside it. Any MEXC office located in the United States is excluded.

The prohibition is addressed to U.S. institutions. By its text it does not order a non-U.S. customer to close an account, and it does not freeze balances. FinCEN says it chose this measure over narrower ones partly because they would leave a path to dollars through "indirect correspondent relationships via other foreign financial institutions". It also says the order puts U.S. and foreign institutions on notice. Our reading is that banks and payment firms outside the U.S. may review their MEXC exposure before any deadline, though the documents do not say that any have done so.

The numbers FinCEN gives

Treasury's headline is "at least $16 billion". The order itself uses $16.7 billion for the same five-year window. These are FinCEN's assessments from blockchain data and non-public information, and no court has tested them.

The categories overlap with one another and with the total, so they should not be added up. The order also says MEXC directly handled about $129 million with Garantex and $4.1 million with its successor Grinex after those designations, and that it was still transacting with both as recently as June 2026.

The order adds about $36 million tied to the Al-Qassam Brigades and other Iran-linked groups, and about $350,000 received by the sanctioned North Korean launderer Sim Hyon Sop between June and September 2025. Over a longer window, May 2018 to July 2026, it counts more than $13 billion in direct transactions with at least four exchanges the UK has sanctioned.

FinCEN sizes MEXC at more than $1 billion in daily transactions and about $5 billion in reserves, among the 20 largest exchanges by volume. It says it assumes part of the business is legitimate and that lawful users "could readily find alternatives".

What MEXC and others have said

PANews reports that MEXC said on X it is assessing the directive, that operations are normal and user assets safe, and that it plans constructive talks with FinCEN and other regulators. It also says it has started an independent review of its anti-money-laundering and sanctions controls. ChainCatcher carries the same statement and adds that MEXC's legal and compliance teams are involved. MEXC's statement does not answer the specific allegations in the reports we read.

One early market response came from a token issuer. Reserve said it and its market makers will stop providing liquidity for LCAP and CMC20 on MEXC and will soon withdraw those funds. Reserve says liquidity on other venues and on-chain is unaffected. If you hold either token on MEXC, expect a thinner order book there.

What the on-chain and market data show so far

Cointelegraph cited DefiLlama's figure of about $4.48 billion in MEXC assets on Friday. DefiLlama's tracked total stood at $4.578 billion on November 5, $4.480 billion on November 6 and $4.429 billion at 09:10 SGT on November 7, a fall of 3.3% over the two days.

Price explains part of that. Tracked BTC holdings barely changed, at 11,794 and then 11,793 coins between the November 6 and November 7 daily marks. Tracked USDT fell from about $1.664 billion to $1.635 billion, or roughly $29 million, in the same window, which is the clearer sign of money leaving. That is small against the total, and the first mark predates the order. DefiLlama tracks disclosed wallets only, so this is a partial view.

Trading has continued. MEXC's public APIs showed $350 million of 24-hour BTCUSDT spot volume and about $2.35 billion on the BTC_USDT perpetual at about 10:52 SGT on November 7. A live order book tells you nothing about withdrawal speed, and we did not test a withdrawal.

What to do if you have funds on MEXC

1. Write down where your funds would go. If the next stop is a U.S. exchange, a U.S. payment firm or a U.S. bank, that route is what closes once the order takes effect.
2. Plan ahead of the date. The clock starts at Federal Register publication, which had not shown up in our search, so the ban would apply in December at the earliest. Your receiving institution may set its own rules sooner; ask it directly.
3. Send a small test withdrawal before a large one, and check the network, the address and the fee on the withdrawal screen.
4. Keep records: deposit and withdrawal history, transaction hashes and account statements. FinCEN admits U.S. firms often cannot refuse incoming crypto before it arrives, and it gives them discretion in cases such as coins that sat for a long time in a private wallet after leaving MEXC. A receiving firm may ask where your coins came from.
5. Review open positions and any LCAP or CMC20 balances separately. Reserve's exit affects those two tokens first.
6. Treat any "MEXC migration", "asset rescue" or "compensation" link as hostile. Use the app you already have and official channels, and give nobody your codes or keys.

Do not try to hide the origin of funds or route around the order. If you compare other venues, our fee tables and exchange profiles list what each charges, and that comparison can wait until your funds are safely under your control.

Earlier warnings about MEXC

The order cites an enforcement action by Seychelles' Financial Services Authority dated May 26, 2026, a Hong Kong SFC warning from March 2024, and a Japanese FSA notice from April 2023. We covered South Korea's October block on MEXC and other exchange websites last month. The U.S. order goes further because it reaches money movement, where those notices dealt with licensing and access.

What we could not confirm

We could not confirm the Federal Register publication date, so the exact effective date is unknown. MEXC's own site returned HTTP 403 to our request, so we read its statement in its X post and in the PANews and ChainCatcher reports. We found no report of frozen customer balances or suspended withdrawals in the sources we opened, which does not prove there are none. Whether Tether, Circle or non-U.S. banks will change how they treat MEXC is also unknown.

The next dates to watch are the Federal Register publication and any FinCEN exemption or condition, since the order reserves authority to grant both.
