The Department of the Treasury is responsible for promoting economic prosperity and ensuring the soundness and security of the U.S. and international financial systems.

The Department 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, the collection of taxes, and the borrowing of funds necessary to run the federal government. The Department works with other federal agencies, foreign governments, and international financial institutions to encourage global economic growth, raise standards of living, and, to the extent possible, predict and prevent economic and financial crises. The Treasury Department also performs a critical and far-reaching role in enhancing national security by improving the safeguards of our financial systems, implementing economic sanctions against foreign threats to the U.S., and identifying and targeting the financial support networks of national security threats.

The Secretary of the Treasury oversees a budget of approximately $13 billion and a staff of more than 100,000 employees.
