Treasury bonds are long-term, fixed income debt securities issued by the U.S. Department of the Treasury. Also known as U.S. Treasury bonds or T-bonds, they are backed by the federal government and pay a fixed rate of interest every six months until maturity. In this article, we’ll explain how Treasury bonds work, how they compare with Treasury bills and notes, and the benefits and risks investors should understand.
How U.S. Treasury bonds work
With a U.S. Treasury bond, the government borrows a dollar amount from you (usually a minimum of $100 and going up in increments of $100 from there) and promises to regularly pay you interest. At the end of the loan term, it gives back the original amount you lent it. And even though the U.S. government credit rating was reduced back in 2011, it's still rated AA+ by Standard and Poor's – which indicates a strong capacity for the issuer to meet financial commitments.
How U.S. Treasury bonds compare to bills and notes
You may be familiar with the three main types of U.S. government Treasuries: bills, notes and bonds. The difference between them is simply the length of the loan you're giving to the government. U.S. Treasury notes are issued in maturities ranging from two years to 10 years, while U.S. Treasury bonds' are issued with 20- or 30-year terms. Both pay interest twice a year.
Treasury bills (more known commonly as "T-bills") are very short-term, maturing between four and 52 weeks. Unlike notes or bonds that pay regular interest payments, when you buy a T-bill, you generally buy it at a discount. Then, when the bill matures, you receive its face value. For example, let's say you pay $9,700 for a 13-week T-bill. The government is basically writing you an IOU for $10,000 and agreeing to pay it back to you in three months.
Comparison Table
| Treasury security | Typical maturity | Interest payments | Best suited for |
|---|
| Treasury bills, or T-bills | 4 to 52 weeks | Sold at a discount; no regular interest payments | Short-term savings or cash management |
| Treasury notes | 2 to 10 years | Fixed interest every six months | Intermediate-term income |
| Treasury bonds | 20 to 30 years | Fixed interest every six months | Long-term income and portfolio diversification |
