FinCEN (FinCEN)

The bureau of the US Treasury that administers the Bank Secrecy Act. FinCEN writes the anti-money-laundering rules applying to financial institutions, receives suspicious activity and currency transaction reports, and maintains the federal register of money services businesses.

Also called: Financial Crimes Enforcement Network

FinCEN’s authority comes from the Bank Secrecy Act and the regulations made under it. Three functions follow. It makes rules — who counts as a money services business, what an anti-money-laundering program must contain, when the travel rule applies. It collects and analyzes reports, principally suspicious activity reports and currency transaction reports, and makes the resulting intelligence available to law enforcement. And it enforces, bringing civil money penalty actions against institutions and, at times, against named compliance officers personally.

What FinCEN does not do

It does not authorize anyone to move money. A US money transmitter needs a license from each state it operates in, granted by that state’s banking or financial services department, and the federal registration filed with FinCEN sits alongside those licenses without substituting for any of them. A company holding a FinCEN registration and no state license is registered and unlicensed, which is not a lawful position to be operating from.

In practice

FinCEN does not license anyone. It receives registrations and reports and enforces the Bank Secrecy Act; the authority to transmit money in the United States comes from the states, one license at a time.

Example

A payments startup files its FinCEN registration in week one and treats the confirmation as permission to launch. It is not. The registration tells the Treasury the business exists and pulls it inside Bank Secrecy Act obligations. Every state where its customers sit still has to grant a license, and operating before they do is unlicensed money transmission.
