What Corporate Bonds Are
What Corporate Bonds Are
A corporate bond is a debt obligation issued by a company. When you buy one, you become a creditor to that company, ranking ahead of all equity holders if the business fails.
Key takeaways
- Corporate bonds represent loans to companies, repaid from operating cash flow or refinancing
- Bondholders sit above shareholders in the bankruptcy priority order
- Coupon payments and principal repayment depend on the issuer's ability and willingness to pay
- Credit ratings estimate default probability and guide bond pricing
- Corporate bonds are traded both at issuance (primary market) and secondhand (secondary market)
The basic structure
When a company needs capital—for acquisitions, expansion, debt refinancing, or working capital—it can borrow by issuing bonds. Unlike a bank loan, which typically stays with the lender, bonds are packaged into tradeable securities and sold to many investors across the capital markets.
The issuer promises to:
- Pay a fixed coupon (interest) semi-annually or annually
- Repay the full principal on a specified maturity date, usually 2–30 years ahead
A $1,000 par bond paying 5% coupon delivers $50 per year in interest. The bondholder receives this stream for the life of the bond, then gets the $1,000 principal back at maturity (assuming no default).
The issuer chooses the coupon to match market conditions. In 2024, when Treasury yields were high, a new investment-grade corporate bond might carry a 5.5% coupon to compensate for credit risk. In 2015, when Treasuries yielded under 2%, corporate coupons were correspondingly lower.
Why companies issue bonds
Bonds compete with bank loans, equity offerings, and retained earnings as sources of capital. Companies choose bonds when:
- Cost-effective: The coupon rate is lower than the hurdle rate for new projects or the cost of equity
- Longer maturity: Bonds typically offer 10–40 year maturities, locking in financing longer than revolving credit facilities
- Market conditions: Strong credit reputation and favorable yields make issuance attractive
- Diversification of sources: Reducing reliance on a single lender or equity dilution
- Liquidity access: Bonds can be resold by investors, creating a secondary market
Apple, Microsoft, Johnson & Johnson, and most large multinational corporations maintain active bond markets. Amazon, which historically avoided debt, began issuing investment-grade bonds in 2009 because yields fell and the company had ample cash flows to service them.
Where bondholders stand in bankruptcy
This is the critical distinction from equity. If a company files for bankruptcy and enters liquidation, proceeds are distributed in this legal order:
- Secured creditors (tax liens, equipment loans, mortgages)
- Unsecured creditors (general corporate bonds, bank loans)
- Preferred shareholders
- Common equity shareholders
A bondholder holding unsecured corporate debt ranks ahead of every shareholder. If liquidation yields 40 cents per dollar of unsecured claims, the bondholder recovers 40% of principal; equity holders typically get zero.
This priority explains why bonds typically yield less than equity (which must compensate for higher risk) and why credit quality matters so much. A company with stable earnings and low leverage can service its debt through economic cycles. A highly leveraged or cyclical business faces higher default risk.
The secondary market
Most bonds are bought not at issuance but in the secondary market—the ongoing trading market where existing bonds change hands. A bond issued by Microsoft in 2022 at 3% coupon might trade at a discount or premium today depending on how yields and credit spreads have moved.
Corporate bonds trade via:
- Dealer networks: Investment banks and fixed-income dealers quote two-way prices to institutional clients
- Electronic platforms: Bloomberg, MarketAxess, and other institutional systems now offer centralized matching
- Brokers: Individual investors can buy corporate bonds through brokerage accounts, though bid-ask spreads are wider than institutional trades
Unlike equities, corporate bond trading is not centralized on a single exchange. Instead, it is a decentralized over-the-counter market dominated by institutional participants. A retail investor buying a single bond may see a 1–2% spread between what they sell for and what they could buy at—a significant friction cost.
The default risk premium
The coupon on a corporate bond must compensate for default risk. In 2024, a 10-year U.S. Treasury yields roughly 4%. A high-quality investment-grade corporate bond (rated AA or AAA) might yield 4.5%—a 50 basis point spread. A lower-rated bond (BBB) might yield 5.5%—a 150 basis point spread over Treasuries.
That spread represents the market's estimate of expected loss from default. Higher spreads signal either higher expected default probability or a requirement for greater compensation per unit of risk. During financial crises (2008, 2020), spreads widen dramatically as investors demand more yield to hold risky debt.
Default is a real risk. During the 2008 financial crisis, roughly 6% of non-financial corporate bonds in the U.S. defaulted. Most mature companies never default, but cyclical industries and leveraged buyouts carry materially higher risk. Holding corporate bonds means accepting the possibility that the issuer, despite its promises, fails to pay.
How corporate bonds fit into a portfolio
For individual investors, corporate bonds are typically accessed through funds rather than individual positions. A fund like LQD (investment-grade corporates) or HYG (high-yield corporates) provides instant diversification across dozens or hundreds of issuers, eliminating the risk that one company's failure wipes out the position.
An all-equity portfolio, concentrated in a single country or sector, has no hedge against equity drawdowns. Corporate bonds fall less steeply in bear markets because they are claims prior to equity. A 60/40 portfolio (60% stocks, 40% bonds) smooths returns and caps downside risk compared to 100% stocks.
Corporate bonds are not growth assets; they provide income and stability. The goal is to collect the coupon and recover principal, not to speculate on price appreciation.

Corporate bonds range from safest (investment-grade) to highest-yielding (high-yield or "junk"). The rating line between BBB and BB represents the most important boundary in credit markets, separating bonds that have passed rigorous credit standards from those where default risk is material.
