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
