What are Treasury Bills?

The US government sells T-Bills to raise money to help fund its debt and its day-to-day operations. When you buy a T-Bill, you are giving the US government a short-term loan. In return, you receive an interest payment when the bill matures. A Treasury Bill (T-Bill) is a type of short-term US debt security with a maturity of one year or less. They’re one of five types of Treasury marketable securities, which are securities that can be transferred or sold before they reach the end of their term. The Treasury Department sells T-Bills in $100 increments with a maximum purchase of $10 million in noncompetitive bids.

T-Bills are widely regarded as a safe investment, as they’re backed by the full faith and credit of the US government.

Treasury Bills vs. bonds

Treasury Bills are a type of short-term debt security issued by the US government, while bonds are a long-term debt security issued by governments and corporations.

Pros and cons of treasury bills


  • Near zero-risk since T-Bills are backed by the US government
  • Low investment minimum of $100
  • Fixed interest rate means stable income
  • No state or local taxes on interest income
  • Purchase T-Bills through the Treasury Department or through a bank or broker


  • T-Bills pay no interest leading up to maturity, only at maturity
  • Fixed interest rate means interest rate risk, so their rate could fall out of favor during periods of rising interest rates

Bottom line

With a low risk of default, low investment minimum and short time horizon, T-Bills may be an appealing place to invest. In an environment where shorter-term yields are higher than longer-term yields, T-Bills may be even more attractive. But they don’t come without disadvantages. Periods of rising interest rates may make existing T-Bills less attractive, but this won’t matter if you plan to hold the bill until maturity.
