A corporate bond is a loan you make to a company, and the company pays you back with interest
When you buy a corporate bond, you are lending money to a business. The company promises to pay you interest on that loan at set times — usually twice a year — and to return your full investment on a specific date called the maturity date. That date might be in 2, 5, 10, or 30 years depending on the bond. You are not buying a piece of the company the way you would with stock; you are a creditor, not an owner.
The company issues bonds instead of borrowing from a bank because it can often borrow larger amounts this way, and sometimes at lower interest rates. For you, a corporate bond is different from a savings account or a stock because the return is fixed — you know exactly how much interest you will receive each year — but you also take on the risk that the company might not pay you back.
Key Takeaways
- A corporate bond is a debt security where you lend money to a company and receive regular interest payments plus your principal back at maturity.
- The interest rate on a bond depends on the company's credit rating, how long until maturity, and overall market conditions when the bond is issued.
- You can hold a bond until maturity or sell it before then, though the price you get depends on interest rates and the company's financial health at the time of sale.
- Corporate bonds carry credit risk — the chance the company cannot pay you back — which is why bonds from stronger companies pay lower interest rates than bonds from weaker ones.
How the interest rate and maturity date are set
When a company issues a bond, it decides two main things: the interest rate (called the coupon rate) and the maturity date. The coupon rate is a percentage of the bond's face value — the amount you lend. If you buy a $1,000 bond with a 5% coupon rate, you receive $50 per year in interest, usually split into two $25 payments.
The company sets the coupon rate based on what investors will accept at that moment. If the company has a strong credit rating and the overall interest rates in the economy are low, the company can offer a lower coupon rate and still find buyers. If the company is riskier or interest rates are high, it must offer a higher coupon rate to attract lenders. The maturity date is fixed when the bond is issued and does not change — if you buy a 10-year bond today, it matures in 10 years, not sooner.
Credit rating and what it tells you about risk
Before you buy a corporate bond, you can look up the company's credit rating. Three major rating agencies — Moody's, Standard & Poor's, and Fitch — assign letter grades to bonds. Ratings range from AAA (highest quality, lowest risk) down to C or D (lowest quality, highest risk). A bond rated BBB or higher is considered investment grade, meaning the company is expected to pay back its debt. Bonds rated below BBB are called high-yield or junk bonds, and they carry much higher risk of default.
The credit rating reflects the rating agency's view of whether the company can afford to pay interest and principal on time. A company with strong earnings, low debt, and stable cash flow gets a high rating. A company struggling with losses or carrying heavy debt gets a lower rating. The rating is not a may provide — it is an assessment. Even highly rated bonds can default if the company's situation changes dramatically.
What happens to a bond's price before maturity
You do not have to hold a bond until maturity. You can sell it to another investor at any time on the secondary bond market. However, the price you receive depends on what has happened since the bond was issued.
If interest rates in the economy have fallen since you bought the bond, your bond becomes more valuable because it pays a higher coupon rate than new bonds being issued. An investor will pay more than face value to buy it from you. If interest rates have risen, your bond becomes less valuable because new bonds pay higher rates. You would have to sell at a discount — below face value — to find a buyer. The company's credit rating can also change. If the company's financial health improves, the bond price rises. If it worsens, the bond price falls.
This price movement matters only if you sell before maturity. If you hold the bond until the maturity date, you receive the full face value regardless of what the price was in the market along the way.
The difference between corporate bonds and government bonds
Corporate bonds and U.S. Treasury bonds both pay interest and return principal at maturity, but they carry different risks. Treasury bonds are backed by the U.S. government, which has never defaulted on its debt. Corporate bonds are backed only by the company's ability and willingness to pay. Because of this difference, Treasury bonds pay lower interest rates than corporate bonds of the same maturity — investors accept lower returns in exchange for lower risk.
Municipal bonds, issued by states and cities, fall somewhere in between. They carry more risk than Treasuries but often less than corporate bonds, and they offer a tax advantage: the interest is usually free from federal income tax. Corporate bond interest is taxed as ordinary income at your federal tax rate.
How to buy and hold corporate bonds
You can buy corporate bonds through a brokerage account — the same type of account you would use to buy stocks. You place an order for a specific bond, and your broker executes the trade. Some bonds trade frequently and are straightforward to buy or sell; others trade rarely and may be harder to move quickly. You can also buy bonds through a bond fund or exchange-traded fund (ETF), which pools money from many investors to buy a basket of bonds.
When you hold individual bonds, you receive interest payments directly, usually twice a year. You are responsible for tracking the maturity date and deciding what to do with your money when the bond matures. With a bond fund or ETF, the fund manager handles buying and selling bonds, and you receive distributions (which may include interest, capital gains, or both) on a schedule set by the fund.
What can go wrong: default and other risks
The main risk with a corporate bond is that the company defaults — fails to pay interest or principal on time. If this happens, you may lose some or all of your investment. Companies in financial distress sometimes restructure their debt, which can mean bondholders receive less than they are owed or receive it later than promised.
Interest rate risk is another factor. If you need to sell a bond before maturity and interest rates have risen, you will receive less than you paid. Inflation risk matters too: if inflation rises significantly, the fixed interest payments on your bond become worth less in real terms. Liquidity risk means you might not be able to sell a bond quickly if you need cash, especially if it is a less common bond or the market is stressed.
Frequently Asked Questions
Can a corporate bond default even if the company is profitable?
Yes. A company can be profitable but still default if it does not have enough cash on hand to pay bondholders, or if it chooses to prioritize other obligations. Default happens when a company cannot or will not pay interest or principal when due, regardless of whether it is making money overall.
What is the difference between a bond's coupon rate and its yield?
The coupon rate is the interest rate set when the bond is issued and never changes. Yield is the actual return you get, which changes based on the price you pay. If you buy a bond below face value, your yield is higher than the coupon rate. If you buy above face value, your yield is lower.
Do I have to pay taxes on corporate bond interest?
Yes. Interest from corporate bonds is taxed as ordinary income at your federal tax rate, and usually at your state and local rates too. This is different from Treasury bonds, where interest is free from state and local tax, and municipal bonds, where interest is usually free from federal tax.
What happens if I sell a bond before maturity for more than I paid?
The difference between what you paid and what you sold it for is a capital gain, and it is taxed at your capital gains rate. If you sell for less than you paid, you have a capital loss, which can offset other gains or, in some cases, reduce your taxable income.
Are corporate bonds safer than stocks?
Corporate bonds are generally less risky than stocks because bondholders get paid before stockholders if a company fails. However, bonds still carry credit risk — the company might default. Stocks can go to zero, but so can bonds, though it is less common.
