The U.S. Treasury market is a financial market where the government issues debt securities to raise funds for various public expenditures. These securities include Treasury bills, Treasury notes, and Treasury bonds, each differing in maturity length and interest payment structures. Investors, including individuals and institutions, buy these securities as a way to lend money to the government in exchange for interest. This market is considered one of the safest investments because it is backed by the full faith and credit of the U.S. government. The yields on these securities serve as a benchmark for other interest rates in the economy, influencing borrowing costs for consumers and businesses.
