The U.S. Department of Treasury is an executive branch of the federal government. It manages national finances once Congress has set fiscal policy. It does this by collecting taxes funding the U.S. debt through Treasury bonds. It also advises the Office of the President on financial, trade and tax policy.

What the Treasury Department Does

Unlike most other federal departments, 98% of the work of the Treasury is done by its ten Bureaus.


  1. The Internal Revenue Service (I.R.S.) collects federal income taxes.
  2. The Treasury Inspector General for Tax Administration prevents IRS fraud.
  3. The Bureau of the Fiscal Service manages the public debt
  4. The U.S. Mint prints postage stamps, currency, and coinage. 
  5. The Bureau of Engraving and Printing designs and manufactures U.S. currency and securities.
  6. The Office of the Comptroller of the Currency regulates national banks.
  7. The Inspector General conducts audits.
  8. The Financial Crimes Enforcement Network investigates and prosecutes tax evaders, counterfeiters, and forgers. It aids the war on terrorism by identifying and freezing funds of terrorists. 
  9. The Alcohol and Tobacco Tax and Trade Bureau enforces laws controlling alcohol and tobacco. It collects firearms and ammunition taxes. 
  10. The Community Development Financial Institution Fund expands credit in poor communities.

The remaining two percent of the work is the office of the  Secretary of the Treasury.

The Secretary manages the U.S. current account deficit by selling Treasury notes and bonds. Since this controls the value of the dollar, it impacts the global economy.

Congress created the Treasury Department and the other two executive departments of Defense and State in 1789. It employs 117,000 people with a $11 billion budget.

It controls $358 billion in tax credits and debt financing.

How It Affects the U.S. Economy

The Treasury auctions Treasury bills, notes, and bonds to pay for the U.S. debt. The ten-year Treasury note sets the benchmark rate for all other long-term debt. The Treasury yield reflects the demand for government debt. The greater the demand, the lower the yield. That reduces interest rates on fixed-interest 15- and 30-year mortgages. Low mortgage rates strengthen the economy by allowing homebuyers to buy more and bigger houses. That stimulates the real estate industry, Low rates also encourage homeowners to borrow more against the equity in their home. That permits them to spend more on consumer products.

Treasury faces a critical role whenever Congress delays raising the debt ceiling. Once the public debt hits the ceiling, Treasury must stop auctioning new Treasury notes. It can extend its ability to pay bills by borrowing from federally-managed retirement funds except for Social Security. It then starts to borrow from the Treasury notes purchased by the Federal Reserve. Once these emergency measures are exhausted, Treasury must rely on incoming tax revenue to pay the government's bills. For most of the year, that's not enough to cover expenses like payments to recipients of Social Security and Medicare benefits.

Federal employees may have to be furloughed. 

If the Treasury doesn't have enough to pay the interest on the debt, then the U.S., would go into debt default. Although it might seem that Congress would want to avoid this at any costs, it did create a debt crisis in 2011, and shut down the government in 2013. For more, see U.S. Debt Crisis.

How It Affects You

By issuing Treasury Bonds, Treasury affects you by influencing mortgage interest rates. It affects your ability to buy and sell your home, and to get equity loans. For more, see How Do Treasury Notes Affect Mortgage Interest Rates?.

It also affects the value of the dollar. That impacts the cost of imports and inflation. Over the long haul, a declining dollar erodes your retirement savings to the point that you may have to keep working past 65.

Treasury affects you more directly, as well. Every April, the I.R.S. expects a check from you, unless it has withheld enough from your paycheck. You may also have U.S. Savings Bonds. If you are concerned about inflation, you might own I Bonds which are from the Bureau of the Public Debt.

Demand for Treasury notes reflects the demand for U.S. dollars. When demand is high, it keeps the price of imports low, reducing inflation. But the U.S. current account deficit threatens to reduce confidence in the dollar. That would increase the cost of imports, aggravating inflation. Worse, it could also trigger a dollar crash.

Unclaimed Money

The Treasury Department has a page devoted to helping you find unclaimed money. That's where you file claims for missing IRS refund checks, Savings bonds, and Treasury bonds. It helps you track property from states you've lived in, class action suits, and unclaimed credit union shares. For more, see U.S. Treasury Unclaimed Money
