Three large banks waited years before filing suspicious activity reports on Jeffrey Epstein, even though they are required to do so within 30 to 60 days of detection. Forward look: If Democrats gain control of Congress, they may look to hold banks responsible for failing to report Epstein's suspicious activity in a timely manner. A Senate investigation into Jeffrey Epstein's finances is casting a spotlight on how major banks monitor — and report — illicit financial activity by high-net-worth clients. The report alleges that JPMorganChase , Bank of America and Deutsche Bank failed to report on Epstein's suspicious transactions in a timely manner. Suspicious activity reports get filed with the Financial Crimes Enforcement Network, or Fincen, a bureau of the Treasury Department.
