What is a Treasury Bond?

A Treasury Bond is a long term fixed income security offered by the United States government with maturities greater than 10 years.

A Treasury Bond pays a fixed rate of interest every 6 months, based on the yield of the bond at its auction.

An investor buys a Treasury Bond at a price that may be above, below or at par (Par is $100 for Treasury Bonds). When the bond matures, you are paid back its par value.

Not to be confused with a Treasury Bill or Treasury Note (Or, See our article here: What’s the Difference?).

Why invest in Treasury Bonds?


Treasury Bonds are typically used for long term investments. They are valued because they are a risk-free asset (if held to maturity) that provides a steady fixed rate of income to investors.

Investors choose Treasury Bonds because of their increase in yield over securities with shorter maturities.

For example as I write this, these are the yields on the treasury securities of various maturities:

Length to Maturity

1 Year

2 Year

3 Year

5 Year

10 Year

30 Year









As you can see, investors who are willing to commit their investments to longer term maturities are paid a higher interest rate.

An investor today who buys $10,000 in 30 year Treasury Bonds will be paid roughly $182.50 every 6 months ($365 per year) for 30 years (and then their $10,000 in principal will be returned).
