On 21 February 2019, representatives of Europol and the Financial Crimes Enforcement Network (FinCEN)of the United States Department of the Treasury met to discuss possibilities for further cooperation, especially with regard to the exchange of financial information. The agencies agreed on the deployment of a FinCEN Liaison Officer to Europol to support and coordinate the cooperation between FinCEN, Europol and EU Member States.

FinCEN carries out its mission by receiving and maintaining financial transactions data, which are analysed and disseminated for law enforcement purposes. It also regulates banks and other financial institutions as far as the combating (detection, reporting and prevention) of money laundering and the countering of terrorism financing are concerned.
