Simple definition
A Treasury bond is a long-term loan you make to the U.S. federal government. In return, the government pays you fixed interest twice a year and returns your original amount when the bond matures — typically after 20 or 30 years. Because it's backed by the U.S. government, it's considered one of the lowest-risk investments around. Think of it like lending money to the most reliable borrower there is.
Why it matters
Treasury bonds are the bedrock of the low-risk part of a portfolio. Backed by the full faith and credit of the U.S. government, they carry very low default risk, so investors use them for steady income and stability. Their interest is also exempt from state and local income tax.
Real-life example
You buy a $1,000 Treasury bond with a 4% coupon rate. Twice a year the government pays you interest, totaling about $40 a year. You collect that income for the life of the bond, and at maturity you get your $1,000 back. You can buy Treasuries directly at TreasuryDirect.gov with no broker.
Formula
Annual interest = face value × coupon rate. A $1,000 bond at a 4% coupon pays $40 a year, usually split into two $20 payments.
Common mistakes
- Assuming 'very low default risk' means the price can't fall — bond prices drop when interest rates rise.
- Locking into a 20- or 30-year term when you may need the cash much sooner.
- Confusing Treasury bonds with shorter Treasury bills and notes.
- Forgetting that selling before maturity can mean taking less than you paid.
Pro tips
- Buy directly from the government at TreasuryDirect.gov to avoid fees.
- Match the bond's term to when you'll actually need the money.
- Remember the interest is exempt from state and local income tax.
- Hold to maturity if you want your full principal back regardless of price swings.

Frequently asked questions
Are Treasury bonds risk-free?
They're considered among the safest investments because they're backed by the U.S. government, so default risk is very low. But no investment is fully risk-free. If interest rates rise, the market price of your bond falls, and inflation can erode what your fixed payments buy over 20 or 30 years.
What's the difference between Treasury bills, notes, and bonds?
They differ mainly in length. Treasury bills mature in a year or less, notes in two to ten years, and bonds in 20 or 30 years. Longer terms usually pay more interest but tie up your money longer. All three are backed by the U.S. government.
How do I buy a Treasury bond?
You can buy new Treasury bonds directly from the government at TreasuryDirect.gov with no fees, or buy them through a broker. Many investors get Treasury exposure through low-cost bond funds instead, which hold a basket of government bonds and handle the buying and reinvesting for you.
