A government bond is a loan you give to a federal, state, or local government, and they pay you back with interest
When you buy a government bond, you are lending money to that government for a set period. The 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 interest rate is fixed when you buy the bond, so you know exactly how much you will earn before you hand over your money.
Governments issue bonds to raise money for things like building roads, funding schools, or paying existing debts. Instead of raising taxes all at once, they borrow from investors like you and repay the loan over time. The bond itself is a certificate or digital record that proves the government owes you that money.
The three main types are Treasury bonds issued by the federal government, municipal bonds issued by states and cities, and savings bonds sold directly to individuals. Each type has different interest rates, maturity lengths, and tax treatment.
Key Takeaways
- A government bond is a debt security where you lend money to a government and receive interest payments until the bond matures.
- Treasury bonds are backed by the U.S. federal government, municipal bonds by states or cities, and savings bonds are sold directly to individuals through the Treasury.
- The interest rate on a bond is locked in when you buy it, so your earnings are predictable and do not change if market rates move.
- You can hold a bond until maturity and get your full principal back, or sell it before maturity on the secondary market at a price that may be higher or lower than you paid.
- Municipal bonds often have tax advantages — the interest may be free from federal income tax and sometimes state income tax too.
How the interest payments and maturity date work
When you own a bond, the government pays you interest on a schedule — usually twice a year, though the exact timing depends on the bond type. This interest payment is called the coupon, even though modern bonds are digital and have no physical coupon to clip. The coupon rate is a percentage of the bond's face value, and it stays the same for the life of the bond.
For example, if you buy a $1,000 Treasury bond with a 4 percent coupon, you receive $40 per year in interest, split into two $20 payments. This happens every year until the maturity date arrives. On that date, the government sends you the final interest payment plus the full $1,000 principal back. You then own nothing — the bond is retired.
The maturity date can be anywhere from a few months to 30 years away, depending on which bond you buy. Shorter bonds are called bills or notes; longer ones are called bonds. The longer the maturity, the higher the interest rate usually is, because you are taking on more risk that inflation or other conditions will change during that time.
The difference between Treasury bonds, municipal bonds, and savings bonds
| Bond Type | Issued By | Interest Tax Treatment | How You Buy It | Typical Maturity Range |
|---|---|---|---|---|
| Treasury bond | U.S. federal government | Free from state and local income tax; subject to federal income tax | Through TreasuryDirect.gov or a broker | 20 to 30 years |
| Treasury note | U.S. federal government | Free from state and local income tax; subject to federal income tax | Through TreasuryDirect.gov or a broker | 2 to 10 years |
| Treasury bill | U.S. federal government | Free from state and local income tax; subject to federal income tax | Through TreasuryDirect.gov or a broker | 4 weeks to 1 year |
| Municipal bond | State or local government | Usually free from federal income tax; may be free from state income tax if you live in the issuing state | Through a broker | 5 to 30 years |
| Series I savings bond | U.S. federal government | Free from state and local income tax; federal tax deferred until you cash it in | Through TreasuryDirect.gov only | 30 years (can cash after 1 year) |
| Series EE savings bond | U.S. federal government | Free from state and local income tax; federal tax deferred until you cash it in | Through TreasuryDirect.gov only | 30 years (can cash after 1 year) |
Treasury bonds, notes, and bills are all issued by the U.S. Department of the Treasury. The difference is maturity length: bills mature in less than a year, notes in 2 to 10 years, and bonds in 20 to 30 years. All three are backed by the full faith and credit of the U.S. government, which means the risk of the government failing to pay you back is extremely low. You can buy them directly through TreasuryDirect.gov with no fees, or through a broker if you want more flexibility in timing or amount.
Municipal bonds are issued by states, cities, counties, and other local governments to fund schools, water systems, highways, and other public projects. The main advantage is the tax treatment: the interest is almost always free from federal income tax, and if you live in the state that issued the bond, it is usually free from state income tax too. This tax break makes the effective interest rate higher than the stated rate for many people. You buy municipal bonds through a broker, not directly from the government.
Savings bonds — Series I and Series EE — are sold directly to individuals through TreasuryDirect.gov and cannot be bought through a broker. Series I bonds have interest rates that adjust every six months based on inflation, so your earnings keep pace with rising prices. Series EE bonds have a fixed rate for the life of the bond. Both require you to hold them for at least one year before cashing them in, and if you cash them in before five years, you lose the last three months of interest as a penalty.
What happens if you sell a bond before it matures
You do not have to hold a bond until maturity. You can sell it on the secondary market — a marketplace where existing bonds trade between investors — at any time. The price you get depends on what has happened to interest rates since you bought it.
If interest rates have fallen since you bought your bond, your bond becomes more valuable because it pays a higher rate than new bonds being issued. You can sell it for more than you paid. If interest rates have risen, your bond becomes less valuable because new bonds pay higher rates. You would have to sell it for less than you paid to find a buyer.
This price movement is why bonds are considered less risky than stocks but not risk-free. If you need your money before maturity and interest rates have risen, you take a loss. Savings bonds cannot be sold on the secondary market — you can only cash them in directly with the Treasury, and only after holding them for one year.
Why people buy government bonds
Government bonds are popular because the interest rate is locked in and known upfront. You do not have to guess or hope — you know exactly what you will earn each year. This predictability makes bonds useful for people who want steady income and are willing to accept a lower return in exchange for lower risk.
Bonds are also considered safe because governments are unlikely to default on their debts. A U.S. Treasury bond is backed by the taxing power of the federal government, which makes it one of the safest investments available. Municipal bonds carry slightly more risk because local governments are smaller, but default is still rare.
Another reason people buy bonds is diversification. Bonds often move in the opposite direction from stocks — when stock prices fall, bond prices often rise — so holding both can smooth out the ups and downs in your overall portfolio. Bonds also produce income through coupon payments, which can be reinvested or used to cover living expenses.
The relationship between bond prices and interest rates
Bond prices and interest rates move in opposite directions. This relationship is one of the most important things to understand about how bonds work in the real world.
Imagine you bought a $1,000 Treasury bond paying 3 percent interest per year. You receive $30 annually. If the Federal Reserve raises interest rates and new Treasury bonds now pay 5 percent, your old bond paying 3 percent becomes less attractive. If you try to sell it, buyers will offer you less than $1,000 because they can buy a new bond paying more interest elsewhere. The price drops to restore the yield to match the market rate.
The opposite happens when interest rates fall. If new bonds pay 1 percent and yours pays 3 percent, your bond becomes more valuable. Buyers will pay more than $1,000 to own it because it pays above-market interest. The price rises.
This price movement only matters if you sell before maturity. If you hold the bond until the maturity date, you always get your full principal back regardless of what happened to prices in between. This is why bonds are sometimes called "buy and hold" investments.
Frequently Asked Questions
Are government bonds completely safe?
U.S. Treasury bonds are backed by the federal government's taxing power and are considered one of the safest investments. Default is extremely unlikely. Municipal bonds carry slightly more risk because local governments are smaller, but default is still rare. The main risk with any bond is that interest rates will rise, making your bond worth less if you need to sell before maturity.
Can I lose money on a government bond?
If you hold a bond until maturity, you get your full principal back — no loss. If you sell before maturity and interest rates have risen, the price will be lower than what you paid, so you lose money on the sale. You cannot lose money on a savings bond if you hold it to maturity, but you lose three months of interest if you cash it in before five years.
How much interest do government bonds pay?
Interest rates vary by bond type, maturity length, and current market conditions. Treasury bills and short-term notes typically pay lower rates than longer-term bonds. Municipal bonds often pay less than Treasury bonds of the same maturity, but the tax advantage makes them competitive. You can see current rates on TreasuryDirect.gov and through any broker.
What is the difference between a bond and a stock?
A bond is a loan — you lend money to a government and receive fixed interest payments. A stock is ownership — you own a small piece of a company and may receive dividends and price appreciation. Bonds are generally less risky but offer lower returns. Stocks are riskier but have higher growth potential over long periods.
Do I have to pay taxes on bond interest?
Interest from Treasury bonds is subject to federal income tax but free from state and local income tax. Interest from municipal bonds is usually free from federal income tax and may be free from state income tax if you live in the issuing state. Interest from savings bonds is subject to federal income tax, but you can defer paying it until you cash the bond in. Consult a tax professional about your specific situation.
