Credit default swaps is a financial derivative instrument and academic concept centered on the transfer and management of credit risk associated with a reference entity or asset. This concept investigates the structure, pricing, and market dynamics of bilateral contracts where one party provides credit protection in exchange for periodic payments, contingent upon the occurrence of a defined credit event for the reference entity. Key characteristics include the segregation of credit risk from the underlying asset, the potential for both hedging and speculative applications, and its significance lies in its role as a major credit risk transfer mechanism, subject to extensive research regarding its impact on market liquidity, counterparty risk, and systemic financial stability.
