A government bond is a loan you make to the federal, state, or local government
When you buy a government bond, you are lending money to a government body. That government promises to pay you back the full amount on a specific date, called the maturity date, and to pay you interest along the way. The government uses the money from bond sales to fund roads, schools, military operations, or other public expenses. You get a steady income stream and your principal back; the government gets the cash it needs without raising taxes immediately.
Government bonds are considered low-risk investments because governments have the power to tax and print currency — they almost never default. This safety comes with a trade-off: the interest rate (called the yield) is usually lower than what you could earn from stocks or corporate bonds. The longer you agree to lend the money, the higher the yield typically is, because you are giving up access to your cash for a longer period.
Key Takeaways
- A government bond is a debt security where you lend money to a government and receive interest payments plus your principal back at maturity.
- U.S. Treasury bonds, notes, and bills are issued by the federal government; municipal bonds are issued by states and cities.
- Government bonds pay less interest than riskier investments because they are backed by the government's taxing power and are considered very safe.
- You can buy bonds directly from the U.S. Treasury through TreasuryDirect, or through a bank or brokerage firm, and you can sell them before maturity if you need the cash.
The three main types of U.S. government bonds
Treasury bills (T-bills) mature in less than one year — typically 4, 8, 13, or 26 weeks. You buy them at a discount to their face value and receive the full face value at maturity; the difference is your interest. A $1,000 T-bill might cost you $990, and you get $1,000 back in a few months.
Treasury notes mature in 2, 3, 5, 7, or 10 years. They pay interest twice a year and are the most commonly owned Treasury securities. A 10-year note might pay 4% annually, meaning you receive $40 per year on a $1,000 bond, plus your $1,000 back after 10 years.
Treasury bonds mature in 20 or 30 years and also pay interest twice yearly. They offer higher yields than shorter-term bonds because you are committing your money for decades. The 30-year bond is sometimes called the "long bond" and is watched closely by economists as a sign of where interest rates are headed.
Municipal bonds are issued by states, cities, and counties to fund local projects like schools, water systems, or transit. The key difference: interest from municipal bonds is usually not taxed by the federal government, and often not by your state either. This tax advantage means they pay lower interest rates than Treasury bonds of the same length, but the after-tax return can be higher if you are in a high tax bracket.
How to buy government bonds
You can buy U.S. Treasury securities directly from the federal government through TreasuryDirect, a free online platform run by the Bureau of the Fiscal Service. You set up an account, link a bank account, and bid on new bonds during regular auctions. There are no fees, no middleman, and you own the bonds outright. This is the cheapest way to buy Treasuries if you plan to hold them to maturity.
You can also buy Treasuries through a bank or brokerage firm like Fidelity, Vanguard, or Charles Schwab. These firms charge a small fee or commission, but they make it easier to buy and sell bonds before maturity, and they handle the paperwork. If you think you might need to sell before the maturity date, a brokerage account gives you more flexibility.
Municipal bonds are sold through brokers and financial advisors, not directly from the government. You will need a brokerage account to buy them. The secondary market for municipal bonds is less liquid than the Treasury market, meaning it can be harder to sell them quickly if you need cash.
What happens to bond prices when interest rates change
If you hold a bond to maturity, you get your full principal back no matter what happens to interest rates. But if you sell a bond before it matures, its price in the secondary market rises and falls based on current interest rates.
When interest rates go up, existing bonds become less attractive because new bonds pay more. If you own a bond paying 3% and new bonds are paying 5%, you would have to sell your bond at a discount to find a buyer. The longer the bond's maturity, the bigger the price drop, because the buyer is locked into a low rate for longer.
When interest rates go down, your existing bond becomes more valuable. A bond paying 5% is worth more when new bonds only pay 3%. This is why long-term bonds are more sensitive to interest rate changes than short-term bonds — the interest rate risk is larger over a longer time horizon.
The difference between yield and interest rate
The coupon rate is the interest rate printed on the bond when it is issued — it never changes. A bond with a 4% coupon pays 4% of its face value every year, period.
The yield is the actual return you get, and it changes based on what you paid for the bond. If you buy a bond at face value, the yield equals the coupon rate. But if you buy it at a discount (below face value), your yield is higher than the coupon rate. If you buy it at a premium (above face value), your yield is lower. Yield is what matters for your actual return on investment.
Why homeowners and savers own government bonds
Government bonds are popular with people who want steady income without stock market risk. Retirees often hold bonds because they need predictable cash flow and cannot afford big losses. People saving for a specific goal — a down payment, a child's college fund — use bonds as a safer alternative to stocks.
Bonds also act as a hedge in a diversified portfolio. When stocks fall, bond prices often rise (especially when interest rates drop), so bonds cushion the blow. Financial advisors typically recommend a mix of stocks and bonds based on your age and risk tolerance — younger people hold more stocks, older people hold more bonds.
For homeowners specifically, understanding bonds matters because bond yields influence mortgage rates. When Treasury yields rise, mortgage rates usually rise too. If you are considering refinancing or shopping for a mortgage, watching the 10-year Treasury yield gives you a sense of where rates are headed.
Frequently Asked Questions
Can I lose money on a government bond?
If you hold the bond to maturity, you get your full principal back — no loss. If you sell before maturity and interest rates have risen, you will sell at a discount and lose money. The longer the bond, the bigger the potential loss. But the government itself will not default on a Treasury bond.
What is the difference between a Treasury bond and a savings bond?
Treasury bonds are sold in auctions and trade on the secondary market. Series I and Series EE savings bonds are sold directly to individuals by the government and cannot be traded; you hold them until maturity or cash them in. Savings bonds have different rules about when you can cash them and what penalties apply.
Do I have to pay taxes on bond interest?
Interest from U.S. Treasury bonds is taxed by the federal government but not by most states. Interest from municipal bonds is usually not taxed by the federal government or your state. Interest from corporate bonds is fully taxable. You report bond interest on your tax return each year.
What happens if I need to sell my bond before it matures?
You can sell it on the secondary market through a broker. The price depends on current interest rates and how much time is left until maturity. If rates have risen since you bought it, you will sell at a loss. If rates have fallen, you will sell at a gain. The transaction takes a few days to settle.
Are government bonds a good investment right now?
That depends on your goals, time horizon, and what interest rates are at the moment you buy. Bonds are not meant to beat inflation or stocks over long periods — they are meant to provide safety and steady income. If you need the money in a few years and want to avoid risk, bonds make sense. If you are saving for retirement decades away, stocks typically offer better long-term returns.
