Corporate Bonds: Credit Spreads, Seniority, and Risk

Key Takeaways

• Corporate bond yield equals the Treasury rate at the same maturity plus a credit spread for default and liquidity risk.
• Senior secured bonds have the highest recovery in bankruptcy; subordinated bonds yield more to compensate for lower priority.
• TRACE provides post-trade transparency for US corporate bonds, showing recent transaction prices within 15 minutes.
• Credit spreads widen during economic deterioration even without actual defaults, driving mark-to-market losses.

What It Is

When a corporation needs funding for operations, acquisitions, or refinancing, it can borrow from the public by issuing bonds. The bond contract, called an indenture, specifies the coupon rate, maturity date, payment schedule, and covenants designed to protect bondholders. Covenants might limit additional borrowing or require the company to maintain certain financial ratios.

Corporate bonds sit in the capital structure below bank loans and above equity. If the company fails, secured and senior creditors get paid first, and common shareholders get whatever is left, which is usually nothing.

The Intuition

Bond investors care about two questions. Will I get my coupons on time? Will I get my principal back at maturity? Credit rating agencies summarize the answer into letter grades from AAA down to D, and the market prices each bond accordingly. A AAA-rated bond yields close to Treasuries. A CCC-rated bond yields several percentage points higher because the odds of default are real.

That extra yield above Treasuries is called the credit spread. Spreads widen when the economy weakens, when the issuer's earnings deteriorate, or when investors as a group demand more compensation for risk. The spread is the single most important variable in corporate bond pricing after the underlying Treasury yield.

How It Works

Corporate bonds are ranked by seniority in the capital structure. The three broad tiers are:

• Senior secured. Backed by specific collateral such as property or equipment. Highest recovery rate in bankruptcy.
• Senior unsecured. No collateral, but a senior claim on the company's general assets and cash flows. Most investment-grade corporate debt lives here.
• Subordinated (junior). Paid only after senior creditors are made whole. Higher coupon to compensate.

Total yield to the investor decomposes roughly as:

corporate bond yield = Treasury yield (same maturity) + credit spread

Most corporate bonds in the United States trade over the counter rather than on exchanges. Post-trade transparency comes from the Trade Reporting and Compliance Engine (TRACE), run by FINRA since July 2002. Members must report eligible transactions as soon as practicable and no later than 15 minutes after execution, and more than 80 percent of reports arrive within five minutes. TRACE data covers transactions for corporate and agency bonds for the past ten years and is the main way retail investors can see recent prints on a given CUSIP.

Indentures can include embedded options. A callable bond lets the issuer redeem early if rates fall. A putable bond lets the investor sell back at par if certain conditions are met. Both options change the yield calculation and are covered in dedicated articles.

Settlement for US corporate bonds moved to T+1 on May 28, 2024, matching the cycle already used for equities. The buyer pays the accrued interest since the last coupon on top of the quoted clean price.

Worked Example

A five-year senior unsecured bond from a BBB-rated industrial company offers a 5.50 percent coupon at par. The five-year Treasury yields 4.20 percent on the same day.

Credit spread: 5.50 - 4.20 = 1.30 percent, or 130 basis points.

Six months later the same issuer reports disappointing earnings. The market now demands 200 basis points of spread. The Treasury yield is unchanged, so the bond's required yield is 4.20 + 2.00 = 6.20 percent. Because the coupon is fixed at 5.50 percent, the price falls until the new yield is reached. The bondholder sees a mark-to-market loss even though no coupon was missed.

Common Mistakes

1. Focusing on coupon instead of yield. The coupon is fixed at issuance. What you actually earn is the yield to maturity based on the price you paid today. A bond with a 7 percent coupon trading above par may offer a lower yield than a 4 percent coupon trading below par.

2. Ignoring the indenture. Call features, put features, and covenants materially change the risk and return. Read the key terms before buying, especially the call schedule.

3. Treating investment grade as safe. Investment-grade bonds default far less often than high yield, but they are not risk free. Large investment-grade issuers have been downgraded and defaulted, and prices can fall sharply on credit news even without default.

4. Underestimating liquidity costs. Most corporate bonds trade infrequently. Bid-ask spreads on retail-sized lots can be wide. Check TRACE for recent prints before accepting a dealer quote.

5. Confusing credit spread with return. A widening spread means the bond price is falling. A narrowing spread means the bond is gaining. Spread is the price the market charges for credit risk, not a yield you earn automatically.

Frequently Asked Questions

What is an indenture and why does it matter for bondholders? An indenture is the legal contract governing a bond issue, specifying the coupon, maturity, payment schedule, and any protective covenants. Covenants may restrict additional borrowing, require minimum financial ratios, or limit asset sales. They provide bondholders legal protections; understanding them is essential before purchasing any corporate bond because violations can trigger technical defaults or accelerated repayment.

How does TRACE help retail investors buying corporate bonds? TRACE, run by FINRA, publishes the price, yield, and size of corporate bond trades in near real time. Before the 2002 launch of TRACE, retail investors had no way to verify whether a dealer's quote was fair. Today you can search any CUSIP on FINRA's website or TRACE data feeds to see what the bond actually traded at recently, making it much harder for dealers to overcharge.

Why do corporate bond spreads widen during recessions even if a specific company is healthy? Spread widening during a downturn is partly a compensation adjustment for higher systemic default risk and partly a demand-and-supply effect. Investors broadly become more risk-averse and require more compensation, so prices fall and spreads widen across the credit quality spectrum. Even a financially strong company's bonds can widen if the overall market demands a higher credit risk premium.

What is the difference between senior and subordinated corporate debt? In a bankruptcy or liquidation, claims are paid in the order they rank in the capital structure. Senior secured creditors are paid first using collateral proceeds. Senior unsecured creditors follow from remaining general assets. Subordinated bondholders wait until all senior claims are satisfied, often receiving little or nothing. The extra yield on subordinated bonds compensates for this lower priority.

How are US corporate bond settlement and pricing conventions structured? US corporate bonds settle on a T+1 basis since May 2024. Trades are quoted on a clean-price basis, meaning accrued interest since the last coupon is added separately to get the full settlement amount (dirty price). Bonds are quoted as a percentage of par, so 99.50 means $995 per $1,000 face, with accrued interest added on top.
