How FinCEN labeled MEXC in November 2026
FinCEN’s order against MEXC Global shows how much weight the label carries. The agency announced it on November 6, 2026, cutting the exchange off from the US financial system over at least $16 billion of illicit transactions, by FinCEN’s account.
MEXC is a Seychelles company, the order itself notes. FinCEN still calls it a “money transmitter”, because a crypto exchanger moves “funds or value that substitutes for currency.” The ban then lands on every US financial institution defined in 31 CFR 1010.100(t), and that list puts money services businesses next to banks and broker-dealers.
The order takes effect on December 10, 2026, 30 days after the Federal Register printed it on November 10.
Seven kinds of business
The definition in 31 CFR 1010.100(ff) covers a person “wherever located” that does business wholly or in substantial part within the United States in one of seven roles. These are dealer in foreign exchange, check casher, issuer or seller of traveler’s checks or money orders, provider of prepaid access, money transmitter, the US Postal Service and seller of prepaid access.
Banks are left out. So are firms registered with and regulated by the SEC or the CFTC. Several roles count only above $1,000 for one person on one day, but FinCEN’s registration page says no such threshold applies to money transmitters.
For crypto, FinCEN’s 2019 guidance says exchangers and administrators generally qualify as money transmitters, while users do not. Every MSB must also keep an effective anti-money-laundering program, a duty set out in 31 CFR 1022.210.
Registration and the public list
Under 31 CFR 1022.380, a new business files within 180 days of being established and renews every two calendar years. A foreign firm must name a US agent to accept legal papers, and the duty applies “whether or not licensed as a money services business by any State,” so state licenses are a separate matter.
The results show up in FinCEN’s MSB Registrant Search, which listed 29,453 registered MSBs when read on November 10, 2026, in an update dated November 3. Each entry shows the legal and trading names, the address, the activities the firm declared, the states it works in, its number of branches and the dates the form was signed and received.
Registered is not approved
The misreading FinCEN tackles at the top of its search page is to take a listing as a seal of approval. Fraudsters claim to be MSBs “approved” or “endorsed” by FinCEN, the page says, and inclusion “is not a recommendation, certification of legitimacy, or endorsement of the business by any government agency.” FinCEN does not vet what registrants submit, it adds.
The second misreading runs the other way. Holding coins in a self-custody wallet does not make you an MSB, since the 2019 guidance says a person using an unhosted wallet to buy goods or services on their own behalf is not a money transmitter.
Outside the US the label changes. The EU’s nearest term for an exchange is crypto-asset service provider, a firm authorized under Article 59 of MiCA. Before you send money through a US platform, search FinCEN’s list by its exact legal name, then look for the state licenses it holds.
