Treasury bills, or T-bills, are short-term debt obligations issued by the U.S. government. They are considered one of the safest investments available, as they are backed by the full faith and credit of the United States. T-bills are sold at a discount from their face value and mature in one year or less. Investors can make money with T-bills by holding them until maturity and collecting the face value, or by selling them in the secondary market before maturity.
T-bills are an important part of the U.S. financial system. They provide a safe and liquid investment for individuals and institutions, and they help the government finance its short-term borrowing needs. T-bills have been around for over a century, and they have a long history of providing stable returns for investors.
