The data (FinCen Files) contains information on more than $35 billion in transactions dated from 2000-2017 that were flagged by financial institutions as suspicious to United States authorities. The map only displays cases where sufficient details about both the originator and beneficiary banks were available, and is designed to illustrate how potentially dirty money flows from country to country around the world, via U.S.-based banks. The data in this map represents a fraction of the more than $2 trillion worth of transactions found in the FinCEN Files.

This map also provides information about the U.S.-based “correspondent” banks that allow financial institutions in more than 150 countries and territories to process payments in U.S. dollars.
