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 corporation. The company uses that money for operations, equipment, or expansion. In return, the company promises to pay you interest at a fixed rate and return your principal on a specific date. You are not buying ownership in the company — you are a creditor, not a shareholder. If the company goes bankrupt, bondholders get paid before stockholders do, which is why bonds are generally considered less risky than stocks.

The company issues the bond with three key pieces of information printed on it: the face value (the amount you lend), the coupon rate (the interest percentage), and the maturity date (when you get your money back). A typical corporate bond might have a face value of $1,000, a coupon rate of 5%, and a maturity date 10 years away. That means the company pays you $50 per year for 10 years, then returns your $1,000 at the end.

Key Takeaways

  • You lend money to a corporation and receive fixed interest payments until the bond matures, at which point the company returns your principal.
  • The coupon rate is the interest percentage the company pays you annually, and it is set when the bond is issued and does not change.
  • Bond prices move in the opposite direction of interest rates — when rates rise, existing bonds become less valuable because new bonds pay more.
  • You can hold a bond until maturity or sell it before then on the secondary market, though the price you receive depends on current market conditions.
  • Corporate bonds carry credit risk, meaning the company might fail to pay interest or return your principal if it runs into financial trouble.

How the coupon rate and maturity date work together

The coupon rate is the interest rate the company promises to pay you, expressed as a percentage of the bond's face value. If you buy a $1,000 bond with a 5% coupon, you receive $50 per year. This rate is locked in when the bond is issued and never changes, even if market interest rates rise or fall. The company must pay it regardless of its profitability.

The maturity date is when the company must return your full principal. Corporate bonds typically mature in 2 to 30 years, though some are shorter or longer. A bond that matures in 2 years is called short-term; one that matures in 10 or more years is long-term. The longer the maturity, the more risk you take on — more time means more can go wrong with the company — so longer-term bonds usually offer higher coupon rates to compensate you for that risk.

Why bond prices change even though the coupon rate does not

Once a bond is issued, you can sell it to another investor before it matures. The price you receive is not necessarily the face value. Bond prices move in the opposite direction of interest rates. When the Federal Reserve raises interest rates, new bonds issued by companies pay higher coupons. Your old bond, which pays a lower coupon, becomes less attractive, so you have to sell it at a discount to find a buyer. When interest rates fall, your bond's higher coupon becomes more valuable, and you can sell it at a premium.

This matters because it means the return you actually receive depends on when you sell. If you hold a bond until maturity, you always get the face value back, and your total return is predictable. If you sell early, you might gain or lose money depending on where interest rates have moved. A $1,000 bond paying 4% might sell for $900 if new bonds are paying 6%, because a buyer would rather own the new bond. That same bond might sell for $1,100 if new bonds are paying only 2%.

Credit risk: what happens if the company cannot pay

Every corporate bond carries credit risk — the risk that the company will not pay the interest or principal you are owed. If a company's business deteriorates, its credit rating may be downgraded by agencies like Moody's or Standard & Poor's. A downgrade signals higher risk, and the bond's market price falls because investors demand a higher return to hold it. In the worst case, the company files for bankruptcy. Bondholders are creditors, so they are paid before stockholders, but there may not be enough money to pay everyone in full.

Investment-grade bonds are issued by stable, profitable companies with strong credit ratings. High-yield bonds (sometimes called junk bonds) are issued by companies with weaker finances or higher risk. High-yield bonds pay much higher coupon rates because investors demand more compensation for the extra risk. The choice between them depends on how much risk you can tolerate and what return you need.

How you buy and sell corporate bonds

You can buy new corporate bonds directly from the company when they are first issued, usually through a broker or investment firm. You can also buy existing bonds on the secondary market from other investors. Most individual investors buy bonds through a brokerage account, the same way they buy stocks. The broker charges a commission or markup on the transaction.

If you hold the bond until maturity, you do not need to do anything — the company sends you the final interest payment and returns your principal on the maturity date. If you want to sell before maturity, you place a sell order through your broker, just as you would with a stock. The price you receive depends on current interest rates, the company's credit rating, and how much time remains until maturity. Bonds with less time to maturity are less sensitive to interest rate changes, so their prices fluctuate less.

The difference between individual bonds and bond funds

You can buy individual corporate bonds and hold them yourself, or you can invest in a bond fund or bond exchange-traded fund (ETF) that holds many bonds. With individual bonds, you know exactly what you own and when you will be paid. You control whether to hold until maturity or sell. With a bond fund, a manager buys and sells bonds on your behalf, and the fund's value changes daily based on the market prices of the bonds it holds.

Individual bonds work well if you want predictable income and plan to hold until maturity. Bond funds work well if you want diversification across many companies and do not want to manage individual positions. Bond funds also allow you to invest smaller amounts — you might buy a single bond fund share for $50, whereas individual bonds typically cost $1,000 or more. The trade-off is that bond funds charge ongoing management fees, whereas individual bonds do not.

How interest rate changes affect your returns

When the Federal Reserve raises interest rates, newly issued corporate bonds pay higher coupons. Existing bonds with lower coupons become less valuable in the market, so their prices fall. If you need to sell before maturity, you receive less than you paid. When the Fed cuts rates, new bonds pay lower coupons, existing bonds with higher coupons become more valuable, and their prices rise. If you sell early, you can profit.

This is why bond investors pay attention to Fed policy and economic forecasts. If you believe rates will rise, you might prefer short-term bonds or bond funds, because they are less sensitive to rate changes. If you believe rates will fall, longer-term bonds offer more upside if you sell before maturity. If you plan to hold until maturity, interest rate changes do not affect your outcome — you get your coupon payments and your principal back regardless of what happens to the bond's market price.

Frequently Asked Questions

Can I lose money on a corporate bond if I hold it until maturity?

Yes, if the company goes bankrupt or defaults on its debt. You could receive less than the full principal you are owed. However, if the company remains solvent, you receive all your coupon payments and your full principal back on the maturity date, regardless of interest rate changes. Holding to maturity protects you from interest rate risk but not from credit risk.

What is the difference between a bond's yield and its coupon rate?

The coupon rate is the fixed interest percentage the company pays, set when the bond is issued. The yield is the actual return you receive, which depends on the price you paid. If you buy a $1,000 bond with a 5% coupon for $900, your yield is higher than 5% because you paid less. If you buy the same bond for $1,100, your yield is lower than 5%.

How do I know if a corporate bond is safe?

Check the company's credit rating from Moody's, Standard & Poor's, or Fitch. Ratings from AAA to BBB are considered investment-grade and lower risk. Ratings below BBB are high-yield and carry higher risk. Also review the company's financial statements, debt levels, and industry. Bonds from large, profitable companies in stable industries are generally safer than bonds from smaller or struggling companies.

What happens to my bond if the company is acquired?

Usually, the bond remains in place and the new owner assumes the obligation to pay it. However, the terms may change depending on the deal structure. Some acquisitions trigger a change-of-control clause that allows bondholders to sell the bond back to the company at face value. Read the bond's indenture (the legal document) to understand what happens in a merger or acquisition.

Can I buy corporate bonds through my retirement account?

Yes. You can hold individual bonds or bond funds in an IRA, 401(k), or other retirement account. Bonds are often used in retirement portfolios because they provide steady income and are less volatile than stocks. Interest income from bonds held in a traditional IRA or 401(k) is tax-deferred until you withdraw it. Bonds held in a Roth IRA grow tax-free.
