Money transmission regulations are the rules that decide who may accept money from the public in order to send it on, and on what terms. In the United States they come from two levels: each state's licensing statute and the regulations issued under it, and federal anti-money laundering rules. The whole body of rules is described in Money Transmission Law.
Typical state requirements include a money transmitter license, a surety bond, minimum net worth, rules on how customer funds are held, and regular examinations. Most applications are filed through the NMLS. At federal level the Bank Secrecy Act requires registration, an anti-money laundering programme and suspicious activity reporting. Many states have moved toward common standards through the Money Transmission Modernization Act, a model law approved by state regulators in 2021.
