A Certificate of Deposit Is Not a Bond, Though Both Are Fixed-Income Investments

A certificate of deposit (CD) and a bond are both ways to lend money and earn interest, but they work differently and carry different risks. The key difference: when you buy a CD, you lend money to a bank for a set period. When you buy a bond, you lend money to a government or corporation. Banks insure CDs up to $250,000 through the FDIC; bonds have no such protection and their value can drop before maturity.

Both require you to lock up your money for a fixed time and both pay you interest. But a CD is a deposit product—it sits on the bank's balance sheet as a liability they owe you. A bond is a debt security—it can be bought and sold on the open market, and its price changes based on interest rates and the borrower's creditworthiness. If you need your money early from a CD, you typically pay a penalty. If you sell a bond early, you might get less than you paid for it.

Key Takeaways

  • CDs are issued by banks and insured by the FDIC up to $250,000 per account; bonds issued by governments or corporations have no federal insurance.
  • CD interest rates are fixed when you open the account and do not change; bond prices fluctuate based on market conditions and interest rate changes.
  • Early withdrawal from a CD costs you a penalty set by the bank; selling a bond before maturity means accepting whatever price the market offers.
  • CDs are simpler and lower-risk for money you plan to hold until maturity; bonds require more monitoring and carry credit risk if the issuer struggles.

How CDs and Bonds Handle Your Money Differently

When you open a CD, the bank takes your money and uses it for its own lending and operations. You receive a contract stating the interest rate, the term (usually three months to five years), and the maturity date. On that date, the bank returns your principal plus all the interest earned. The FDIC backs this promise—if the bank fails, you get your money back up to $250,000.

When you buy a bond, you are lending directly to the issuer—a city government, the U.S. Treasury, or a corporation. The bond certificate states the interest rate (called the coupon), the maturity date, and the face value. You receive interest payments at regular intervals, usually twice a year. At maturity, the issuer repays the face value. But if the issuer runs into trouble, there is no insurance. You may lose part or all of your investment.

This difference in backing is why CDs feel safer. You know the FDIC will cover you. With a bond, you are betting the issuer will stay solvent. That is why bonds issued by shaky borrowers pay higher interest—the higher rate compensates you for taking on more risk.

What Happens to Your Money If You Need It Early

CDs penalize early withdrawal. The penalty varies by bank and CD term—a three-month CD might charge you one month of interest, while a five-year CD might charge six months or a year. Some banks charge a flat dollar amount instead. You pay the penalty from your interest earnings first, then from your principal if the penalty is large enough. The bank tells you the exact penalty before you open the CD.

Bonds do not have a withdrawal penalty, but they have a market-price problem. If you sell a bond before maturity and interest rates have risen since you bought it, the bond is worth less. Buyers will only purchase it at a discount. If interest rates have fallen, the bond is worth more. You can sell it for a gain. The longer the bond's maturity, the bigger the price swing when rates move. This is why bonds are riskier if you might need the money before the maturity date.

A CD locks you in with a known penalty. A bond locks you in with an unknown price. If you are certain you will hold until maturity, this does not matter. If you might need the money, a CD is more predictable.

Interest Rates: Fixed Versus Changing

CD interest rates are fixed for the entire term. If you lock in 5% on a two-year CD, you earn 5% every year for two years, no matter what happens to market rates. This is predictable and straightforward. You know exactly how much you will have at maturity.

Bond interest rates are also fixed—the coupon does not change. But the bond's market price does. If you hold the bond to maturity, you get the fixed coupon payments and your face value back, so the price swings do not matter. If you sell early, the price matters a lot. Rising interest rates push bond prices down; falling rates push them up. A 10-year Treasury bond bought at 3% loses value if new Treasuries are issued at 5%, because buyers would rather have the new bonds.

CDs avoid this problem entirely because you cannot sell them on a market. The bank holds them until maturity. You get your rate, period. This simplicity is one reason CDs appeal to people who want certainty.

Credit Risk and What Happens if the Issuer Fails

Credit risk is the chance that the borrower cannot pay you back. CDs have almost no credit risk because the FDIC insures them. Even if the bank fails, the FDIC pays you up to $250,000. If you have more than $250,000 in CDs at one bank, the amount over $250,000 is not insured, so some people spread large sums across multiple banks.

Bonds carry real credit risk. U.S. Treasury bonds carry almost none—the federal government has never defaulted. Municipal bonds (issued by cities and states) carry low to moderate risk depending on the issuer's finances. Corporate bonds carry higher risk, especially if the company is struggling. If a corporation goes bankrupt, bondholders are paid after employees and secured creditors, so you might recover only cents on the dollar or nothing at all.

This is why corporate bonds pay higher interest than Treasury bonds. The higher rate compensates you for taking on credit risk. If you want safety close to a CD, Treasury bonds are the choice. If you want higher returns, you take on more risk with corporate bonds.

Which One Fits Your Situation

Choose a CD if you have money you will not touch for a specific period—six months, two years, five years—and you want a may provide return with no market risk. CDs work well for emergency savings, money set aside for a known expense, or funds you want to keep safe while earning more than a savings account. The tradeoff is a lower interest rate and a penalty if you need the money early.

Choose a bond if you can hold it to maturity and you want a higher return than a CD offers. Treasury bonds are safest; municipal and corporate bonds pay more but carry credit risk. Bonds also work if you want to build a ladder of maturity dates so money comes due at different times. If you might need to sell before maturity, bonds are riskier because their price can drop.

Some people use both. A CD might hold emergency money or funds needed within a year. Bonds might hold longer-term savings where the higher rate justifies the risk. The choice depends on how long you can lock up the money and how much safety matters to you.

Frequently Asked Questions

Can I sell a CD before it matures?

Most banks do not allow you to sell a CD on a market. You can withdraw the money early, but you pay a penalty set by the bank. Some banks offer no-penalty CDs that let you withdraw without a fee, but they pay lower interest rates. A few banks do allow CD transfers, but this is uncommon.

Do bonds have FDIC insurance like CDs?

No. Bonds have no federal insurance. If the issuer defaults, you lose money. Treasury bonds are backed by the U.S. government, so default risk is extremely low. Corporate bonds depend on the company's financial health. This is why bonds pay higher interest—you are taking on risk that CDs do not have.

What happens to my CD if the bank fails?

The FDIC covers your CD up to $250,000. If the bank fails, the FDIC pays you the full amount of your CD plus accrued interest, up to the $250,000 limit. If you have multiple CDs at the same bank, they are added together for the insurance limit. Spreading CDs across different banks protects amounts over $250,000.

Can I get my money back from a bond if the company goes bankrupt?

Bondholders are paid from the company's remaining assets, but only after employees and secured creditors. You might recover some money, part of your investment, or nothing. Treasury bonds are backed by the government and have virtually no default risk. Corporate bonds carry real risk, which is why they pay higher interest.

Which pays more interest, a CD or a bond?

It depends on the type of bond and current market conditions. Treasury bonds usually pay less than CDs because they are safer. Corporate bonds often pay more than CDs to compensate for credit risk. Compare rates at the time you are deciding. Remember that higher rates on bonds come with higher risk.
