Module 13: Advanced Derivatives & SwapsAdvanced 20 Min

Lesson 2: 13.2: Credit Default Swaps (CDS) & Default Protection

Analyze single-name and index CDS contracts, protection buyers/sellers, and credit event triggers.

1. How Credit Default Swaps Work

A Credit Default Swap (CDS) functions as financial insurance against the default or restructuring of a reference entity (a corporate bond issuer or sovereign nation).

The protection buyer pays a quarterly premium (spread) to the protection seller. In return, if a defined 'Credit Event' occurs (such as bankruptcy, failure to pay, or debt restructuring), the protection seller must compensate the buyer for the credit loss.

★ Credit Spreads: Widening CDS spreads indicate that market participants perceive a higher probability of default for the reference entity.

2. Single-Name CDS vs. Index CDS

• Single-Name CDS: Protects against the credit default of one specific corporation or sovereign entity.

• Index CDS (e.g., CDX, iTraxx): Standardized baskets of multiple credit entities that allow institutions to trade broad corporate credit risk, portfolio default risk, and systemic macroeconomic health.

A flow diagram with the boxes Protection buyer, Premium payments, Protection seller, Defined credit event, Contract settlement and Buyer compensation
Two parallel flows. Top row: Protection buyer → Premium payments → Protection seller. Bottom row: Defined credit event → Contract settlement → Buyer compensation. Top: the premium leg. Bottom: the settlement that happens only if a credit event occurs. A CDS is a derivative, not the same as regulated insurance, and a wider spread does not only reflect default probability.
