Treasury Notes are government debt securities issued by the U.S. Department of the Treasury to help finance national spending. They typically have maturities ranging from 2 to 10 years and pay interest every six months until they mature. Investors buy Treasury Notes as a relatively safe investment, as they are backed by the full faith and credit of the U.S. government. At maturity, the principal amount is returned to the investor, making them a popular choice for those seeking stable returns.
