US Treasury bond

US Treasury bonds are long-term government debt securities, typically issued with 30-year terms.

New bonds are sold at a par value of $1,000, and existing bonds trade in the secondary market at prices that fluctuate to reflect changing demand. These bonds, sometimes referred to as long bonds, are often used as a benchmark for market interest rates.

While interest on US Treasury bonds is federally taxable, it is exempt from state and local taxes. Treasury bonds are considered among the world's the most secure investments, since they are backed by the full faith and credit of the US federal government.
