Quick Definition

The risk that a borrower will fail to make payments on a debt obligation, leading to potential losses for lenders or bondholders.

What Is Credit Risk?

Credit risk is the possibility that a borrower—whether a corporation, government, or individual—will default on their debt obligations.

Types of Credit Risk:

Default Risk:

  • Complete failure to pay principal or interest
  • Most severe form of credit risk
  • Results in potential total loss

Downgrade Risk:

  • Credit rating lowered
  • Bond price drops even without default
  • Higher borrowing costs for issuer

Spread Risk:

  • Credit spreads widen
  • Market demands higher premium for risk
  • Affects all non-Treasury bonds

Measuring Credit Risk:

  1. Credit ratings: Moody's, S&P, Fitch
  2. Credit spreads: Yield vs. Treasury
  3. CDS spreads: Insurance cost against default
  4. Debt ratios: Coverage and leverage

Credit Spread Example: If Treasury yields 4% and corporate bond yields 6%, credit spread = 2% (200 basis points)

Managing Credit Risk:

  • Diversification: Don't concentrate in one issuer
  • Credit quality: Stick to investment grade
  • Laddering: Spread maturities
  • Research: Analyze issuer fundamentals
  • Bond funds: Professional management

B29.0%
CCC52.3%
