U.S. Treasury Bills

One of the Safest Investments Available

Treasury bills, or T-bills, are typically issued at a discount from the par amount (also called face value). For example, if you buy a $1,000 bill at a price per $100 of $99.986111, then you would pay $999.86 ($1,000 x .99986111 = $999.86111).* When the bill matures, you would be paid its face value, $1,000. Your interest is the face value minus the purchase price. It is possible for a bill auction to result in a price equal to par, which means that Treasury will issue and redeem the securities at par value.

You can buy a bill in TreasuryDirect or Legacy Treasury Direct, or through a bank, broker, or dealer. The table below shows the types of bills available for purchase by each of those means.

You can bid for a bill in two ways:

  • With a noncompetitive bid, you agree to accept the discount rate determined at auction. With this bid, you are guaranteed toreceive the bill you want, and in the full amount you want.

  • With a competitive bid, you specify the discount rate you are willing to accept. Your bid may be: 1) accepted in the full amount you want if the rate you specify is less than the discount rate set by the auction, 2) accepted in less than the full amount you want if your bid is equal to the high discount rate, or 3) rejected if the rate you specify is higher than the discount rate set at the auction.

To place a noncompetitive bid, you may use TreasuryDirect, Legacy Treasury Direct, or a bank, broker, or dealer.

To place a competitive bid, you must use a bank, broker, or dealer.
