A Treasury Note is a type of government debt security issued by the U.S. Department of the Treasury. It has a fixed interest rate and matures in two to ten years. Investors buy Treasury Notes to earn interest over time, and they are considered a safe investment because they are backed by the full faith and credit of the U.S. government. Treasury Notes pay interest every six months until maturity, at which point the principal amount is returned to the investor. They are often used by individuals and institutions as a way to preserve capital while earning a predictable return.
