Treasury Bills (T-Bills)


Treasury Bills (T-Bills) are short-term debt securities issued by the U.S. government to finance their debt. They are backed by the U.S. Treasury’s full faith and credit and have maturity periods ranging from a few days to 52 weeks. T-Bills are sold at a discount to face value and, instead of paying periodic interest, the investor is paid the full face value at maturity.


The phonetic spelling for “Treasury Bills (T-Bills)” is: Treasury: Treh – zhuh – reeBills: BillzT-bills: Tee- Billz

Key Takeaways

  1. Treasury bills, or T-Bills, are short-term debt instruments issued by the U.S. government. They are considered one of the safest investments because they are backed by the credit of the U.S. government. They offer a reliable return with very low default risk.
  2. T-Bills have maturity dates that usually range from a few days to 52 weeks. These short-term debts do not pay an interest rate. Instead, they are sold at a discount from their face value. For example, you could buy a $1,000 T-Bill for $980, and when the bill matures, you will receive the full face value of $1,000. The $20 difference represents the interest you earned.
  3. The yield on T-Bills is the difference between the purchase price and the face value, divided by the face value, then multiplied by 100 to get the percentage. The yield serves as a benchmark for interest rates on other types of loans and investments.


Treasury Bills (T-Bills) are crucial in both the business and finance sectors because they serve as a reliable and virtually risk-free investment instrument, often utilized by companies, financial institutions, and individual investors. As short-term securities issued by a government to finance national borrowing, T-Bills set a benchmark for short-term interest rates in the financial market. They are considered the safest investments because they are backed by the credit of the government. Furthermore, T-Bills influence the country’s money supply and thus can impact inflation and economic stability, making them an important tool for monetary policy.


Treasury bills (T-bills) serve as a cornerstone for short-term borrowing needs of a country. Governments issue these debt instruments to fund a wide array of projects and initiatives. The funds raised from T-bills contribute towards infrastructure development, social projects, sustainability initiatives and even routine administrative expenses of the government. As they are backed by the government, they are seen as a relatively low-risk investment tool, hence, are an attractive option for investors who are averse to high-risk financial instruments.Furthermore, T-bills play a pivotal role in implementing monetary policy. They are a key tool for central banks in controlling money supply in the economy. By selling T-bills, central banks can absorb excess liquidity and thus curb inflation. Conversely, when central banks want to inject liquidity into the system, they buy back these T-bills. In essence, T-bills are not just financing tools for the government, but also levers that can be used to influence the broader economic landscape.


1. U.S. Government’s Financing: The United States government frequently issues Treasury Bills as a method of financing its operations. For example, during the economic crisis triggered by the Covid-19 pandemic, the government used T-Bills extensively to raise funds for stimulus packages. Purchasing these T-Bills helps fund government expenses, but for the buyer or investor, they serve as a short-term investment.2. Corporate Investments: Large companies often have significant cash reserves that are not needed for immediate operations. Instead of leaving this money in a basic savings account, they may choose to invest in T-Bills. A significant example is Apple Inc., as they have been known to invest their excess cash in Treasury Bills as a low risk way to generate additional profit.3. Monetary Policy Implementation: Central banks like the Federal Reserve, often participate in buying and selling Treasury Bills as part of their monetary policy. For instance, when the Federal Reserve wants to increase the money supply, it will buy T-Bills from banks. This provides the banks with more cash that they can lend to businesses and individuals. This was seen during the 2008 recession, when the Fed purchased large quantities of T-Bills to help stabilize the economy.

Frequently Asked Questions(FAQ)

What are Treasury Bills (T-Bills)?

Treasury Bills (T-Bills) are short-term U.S. government debt securities with a maturity period of one year or less. They are usually issued in denominations of $1,000 up to a maximum purchase of $5 million and are considered a safe and low-risk investment option.

How do T-Bills work?

T-Bills are auctioned off by the U.S. Treasury Department. Investors buy them at a price less than their face value, and when they mature, the government pays the holder the full face value. The difference between the purchase price and the face value is the interest earned.

Can you sell T-Bills before they mature?

Yes, T-Bills can be sold on the secondary market before they mature. The price will depend on the demand and current interest rates.

What are the benefits of investing in T-Bills?

T-Bills offer a low-risk investment as they are backed by the U.S. government. They are considered liquid assets as they can be easily sold in the secondary market. Lastly, interest earned from T-Bills are exempt from state and local taxes.

Where can I purchase T-Bills?

T-Bills can be purchased directly from the U.S. Treasury through the TreasuryDirect website, or through banks, brokers, and dealers.

Do T-Bills pay interest?

Unlike traditional interest-bearing securities, T-Bills do not pay periodic interest. Instead, they are sold at a discount from their face value and the investor receives the full face value upon maturity. The difference between the purchase price and the value at maturity is the return to the investor.

How frequently are T-Bills issued?

The U.S. Treasury department issues T-Bills at regular intervals throughout the year. They commonly issue new T-Bills with 4-week (1 month), 13-week (3 month), 26-week (6 month), and 52-week (1 year) maturities.

What are the risks associated with T-Bills?

While T-Bills are generally considered safe investments due to the backing of the U.S. government, they do carry some degree of risk. The primary risk is interest rate risk – if interest rates rise, the value of the T-Bill if sold before maturity could be less than the purchase price. Additionally, since T-Bills have a low return relative to other investments, there is also inflation risk – the risk that the return on the investment doesn’t keep up with inflation.
