Credit Default Swaps: Past, Present, and Future

Credit default swaps (CDS) have grown to be amulti-trillion-dollar, globally importantmarket. The academic literature onCDShas developed in parallel with the market practices, public debates, and regulatory initiatives in this market. We selectively review the extant literature, identify remaining gaps, and suggest directions for future research. We present a narrative including the following four aspects. First, we discuss the benefits and costs of CDS, emphasizing the need for more research in order to better understand the welfare implications. Second, we provide an overview of the postcrisis market structure and the new regulatory framework for CDS. Third, we place CDS in the intersection of law and finance, focusing on agency conflicts and financial intermediation. Last, we examine the role of CDS in international finance, especially during and after the recent sovereign credit crises.
