Office of the Inspector General


OIG Office of Investigations

The Department of the Treasury’s Office of Inspector General (OIG) was established in 1989 by the Secretary in accordance with the Inspector General Act. 
The Office of Investigations is responsible for investigating criminal activity and employee misconduct associated with the operations of the following Treasury Bureaus:
·         United States Mint
·         Bureau of Engraving and Printing
·         Bureau of the Fiscal Service
·         Office of the Comptroller of the Currency
·         Financial Crimes Enforcement Network
·         Alcohol and Tobacco Tax and Trade Bureau
·         Community Development Financial Institution Fund
·         Departmental Offices:
   o   Office of Foreign Assets Control
   o   Office of Terrorism and Financial Intelligence
   o   Office of Financial Stability
Bank Failures
These investigations are related to potentially fraudulent acts that contributed to a bank failure.  In a number of cases, we have partnered with the OIG’s of the Federal Deposit Insurance Corporation (FDIC) and the Board of Governors of the Federal Reserve System to conduct these investigations.
 The objective of this initiative is to bring to justice individuals who impede or defraud the regulatory oversight functions of Treasury’s bank regulators. 
The intent of our collective efforts is to deter others contemplating similar criminal activity and help maintain the public’s confidence in the nation’s financial systems.
Unregistered Money Service Businesses
The term “”Money Services Business” (MSB) includes any person or entity doing business concerning one or more of the following capacities:
·         Check Casher
·         Currency Dealer or Exchanger
·         Issuer of Money Orders, Stored Value Cards or Traveler Checks
·         Money Transmitter
MSB’s must register with the Treasury Department.  Our office is committed to identifying, investigating and bringing to justice illegal MSB’s in an effort to combat acts of potential money laundering, terrorist financing and other threats against our nation’s financial infrastructure.
Treasury Check Fraud
In August 2010, the Office of Investigations embarked on an initiative involving the Check Forgery Insurance Fund (CFIF). The Fund, established in 1941, is a revolving fund administered by the Bureau of the Fiscal Service (Fiscal Service) to settle claims of non-receipt of U.S. Treasury checks.  In the past there have been instances where the claims were fraudulent. 
According to Fiscal Service, millions of dollars in claims settlements are disbursed each year which are filed by criminals involved in U.S. Treasury check fraud.  These disbursements have resulted in the loss of millions of dollars to the government.  In an effort to help law enforcement prosecute criminals, this office has been linking payment data with forgery cases to identify instances where the law has been violated.
