Treasury bills, or T-bills, are short-term debt obligations issued by the U.S. government with maturities ranging from one month to one year. They are considered one of the safest investments available, as they are backed by the full faith and credit of the U.S. government.
In the past, T-bills were only available for purchase through banks or brokers. However, with the advent of the internet, it is now possible to buy T-bills directly from the U.S. Treasury Department’s website.
