Money Services Business (MSB)

A money services business is a category in US federal law under the Bank Secrecy Act, covering seven capacities: dealer in foreign exchange, check casher, issuer or seller of money orders or traveler’s checks, provider of prepaid access, seller of prepaid access, money transmitter, and the US Postal Service.

Also called: money service business · MSBs

A firm becomes a money services business by what it does, not by applying to be one. The federal definition catches a person, wherever located, doing business wholly or in substantial part within the United States in any of seven capacities: dealer in foreign exchange; check casher; issuer or seller of traveler’s checks or money orders; provider of prepaid access; seller of prepaid access; money transmitter; and the US Postal Service. FinCEN treats dealing in convertible virtual currency as money transmission for these purposes.

Size matters for some of those capacities and not for others. A USD 1,000 per person per day threshold applies to dealers in foreign exchange, check cashers and issuers or sellers of traveler’s checks and money orders. There is no dollar threshold at all for money transmitters — any amount counts, and that is the point practitioners most often get wrong. Banks and foreign banks sit outside the definition, as do persons registered with and functionally regulated or examined by the SEC or the CFTC, and a natural person who does any of this infrequently and not for gain.

The consequences are federal and administrative. An MSB registers with FinCEN and renews that registration, maintains an AML program with a designated compliance officer, independent testing and staff training, keeps prescribed records, and files currency transaction reports and suspicious activity reports. Those duties begin with the activity, not with a regulator’s approval.

In practice

Being an MSB triggers federal registration with FinCEN and federal AML obligations. It is not a license and it authorizes nothing: FinCEN does not license money services businesses to operate in the United States, and a registered MSB still needs a state license, with very limited exception, in every state where it operates. Note too that money transmission carries no dollar threshold at all — the USD 1,000 a day test applies to foreign exchange dealers, check cashers and money order or traveler’s check issuers, not to transmitters.
