The Department of the Treasury is the executive agency responsible for promoting economic prosperity and ensuring the financial security of the United States. It was established by an Act of Congress in 1789 to manage government revenue. Treasury operates and maintains systems that are critical to the nation's financial infrastructure, such as the production of coin and currency, the disbursement of payments to the American public, revenue collection, and the borrowing of funds necessary to run the federal government.

The Treasury includes offices such as the Internal Revenue Service (IRS), Office of the Comptroller of the Currency (OCC), Office of Financial Stability, and the Bureau of Engraving and Printing.
