Credit risk is the possibility that a borrower fails to meet their contractual obligations. When you purchase a corporate bond, as we discussed in Bond Fundamentals and Pricing, you receive coupon payments and principal repayment in exchange for lending money to the issuer. However, if the company experiences financial distress and cannot make these payments, you suffer a credit event. This fundamental uncertainty distinguishes corporate and sovereign debt from risk-free government securities, and it explains why investors demand higher yields to compensate for bearing this additional risk.
Understanding credit risk requires recognizing that default is not a binary, all-or-nothing event that occurs predictably. Rather, default probability exists on a continuum, influenced by the borrower's financial health, industry conditions, macroeconomic factors, and countless other variables. The challenge for us is quantifying this probability and pricing it appropriately into financial instruments.
A credit event is a predefined occurrence that triggers the protection payment in a credit derivative contract. Common credit events include bankruptcy, failure to pay, debt restructuring, and obligation acceleration.
The key insight behind credit derivatives is that credit risk can be separated from the underlying bond and traded independently. Just as interest rate swaps allow you to trade interest rate exposure without owning bonds, credit default swaps allow you to trade credit exposure without owning the reference entity's debt. This separation enables participants to acquire, hedge, or transfer credit risk with precision and flexibility not previously available.
