Understanding Credit Spreads
A credit spread is the difference between the yield on a corporate bond and the yield on a comparable risk-free security, typically a government bond. It represents the additional compensation investors demand for bearing credit risk.
Credit Spread Formula
Basic Formula
- Credit Spread = Corporate Bond Yield - Risk-Free Rate
- Example: 6.5% - 4.0% = 2.5% spread
- Measured in basis points (bps)
- Compensation for credit risk
Z-Spread
- Zero-volatility spread
- Constant spread over yield curve
- More accurate for option-free bonds
- Accounts for yield curve shape
Credit Spread Interpretation
Spread Ranges by Credit Quality
Typical credit spreads for different rating categories
Investment Grade
- AAA: 0.5-1.0%
- AA: 0.7-1.5%
- A: 1.0-2.0%
- BBB: 1.5-3.0%
- Low credit risk
High Yield (Junk)
- BB: 3.0-5.0%
- B: 5.0-8.0%
- CCC: 8.0-12.0%
- D: 12.0%+
- High credit risk
Factors Affecting Credit Spreads
| Factor | Impact on Spreads | Reason |
|---|---|---|
| Credit Rating | Higher rating ? Lower spread | Lower default probability |
| Economic Conditions | Recession ? Higher spreads | Increased default risk |
| Liquidity | Low liquidity ? Higher spreads | Illiquidity premium |
| Maturity | Longer maturity ? Higher spreads | Greater uncertainty |

Spread Dynamics
Widening Spreads
- Increased perceived risk
- Economic uncertainty
- Credit rating downgrades
- Flight to quality
Narrowing Spreads
- Improved credit quality
- Economic recovery
- Credit rating upgrades
- Risk appetite increase
Option-Adjusted Spreads
OAS Calculation
- Accounts for embedded options
- Callable and putable bonds
- More accurate for complex bonds
- Uses option pricing models
OAS vs Z-Spread
- Z-Spread: Constant spread
- OAS: Adjusts for options
- OAS typically lower than Z-Spread
- OAS better for valuation
