We analyze the sovereign CDS market for 57 countries, using a novel dataset comprising weekly positions and turnover data. We document that CDS markets - measured relative to a country's debt - are larger for smaller countries, countries with a rating just above the investment-grade cutoff, and countries with weaker creditor rights. Analyzing changes in credit risk, we find that rating changes matter but only for negative rating events (downgrades and negative outlooks). In particular, weeks with downgrades and negative outlooks are associated with a significantly higher turnover in the sovereign CDS market - even after controlling for changes in sovereign CDS spreads. We conclude that agencies' ratings are a major determinant of the size of the sovereign credit default swap market.

The European Short Selling Regulation (the 'Regulation') not only restricts the short selling of shares but (largely in response to the European sovereign debt crisis) also extends its reach into regulating the sovereign debt market. In particular, the Regulation imposes a prohibition on entering into uncovered sovereign credit default swaps (CDSs): a functionally equivalent mechanism to short selling the underlying bonds. This paper provides an overview of sovereign CDSs and their uses and places the concerns voiced about sovereign CDSs in context through an analysis of the relevant economic literature. It then discusses the provisions introduced by the Regulation in the light of these findings. The paper suggests that there are many benefits to using sovereign CDSs and little to support the view that developments in the sovereign CDS markets aggravated the sovereign debt crisis. The restrictions may also reduce interest in the underlying bond markets and so may in fact harm the sovereign issuers the provisions were designed to protect.

This book provides a comprehensive overview for various segments of the global credit default swap (CDS) markets, touching upon how they were affected by the recent financial turmoil. The book uses empirical analysis on credit default swap markets, applying advanced econometric methodologies to the time series data. It covers not only well-studied sovereign credit default swap markets but also sector credit default swap indices (i.e., CDS index for the banking sector) and corporate credit default swap indices (i.e., Markit iTraxx Japan CDS index), which have not been fully examined by the previous literature. The book also investigates causality and co-movement among several credit default swap markets, or between CDS and other financial markets.

Credit Default Swaps: A Survey is the most comprehensive review of all major research domains involving credit default swaps (CDS). CDS have been growing in importance in the global financial markets. However, their role has been hotly debated, in industry and academia, particularly since the credit crisis of 2007-2009. The authors review the extant literature on CDS that has accumulated over the past two decades and divide the survey into seven topics after providing a broad overview in the introduction. The second section traces the historical development of CDS markets and provides an introduction to CDS contract definitions and conventions. The third section discusses the pricing of CDS, from the perspective of no-arbitrage principles, structural, and reduced-form credit risk models. It also summarizes the literature on the determinants of CDS spreads, with a focus on the role of fundamental credit risk factors, liquidity and counterparty risk. The fourth section discusses how the development of the CDS market has affected the characteristics of the bond and equity markets, with an emphasis on market efficiency, price discovery, information flow, and liquidity. Attention is also paid to the CDS-bond basis, the wedge between the pricing of the CDS and its reference bond, and the mispricing between the CDS and the equity market. The fifth section examines the effect of CDS trading on firms' credit and bankruptcy risk, and how it affects corporate financial policy, including bond issuance, capital structure, liquidity management, and corporate governance. The sixth section analyzes how CDS impact the economic incentives of financial intermediaries. The seventh section reviews the growing literature on sovereign CDS and highlights the major differences between the sovereign and corporate CDS markets. The eighth section discusses CDS indices, especially the role of synthetic CDS index products backed by residential mortgage-backed securities during the financial crisis. The authors close with our suggestions for promising future research directions on CDS contracts and markets.

In reduced-form pricing models, it is usual to assume a fixed recovery rate to obtain the probability of default from credit default swap prices. An alternative credit risk measure is proposed here: the maximum recovery rate compatible with observed prices. The analysis of the recent debt crisis in Argentina using this methodology shows that the correlation between the maximum recovery rate and implied default probabilities turns negative in advance of the credit event realization. This empirical finding suggests that the maximum recovery rate can be used for constructing early warning indicators of financial distress.

We investigate the pricing of sovereign credit risk over the period 2008-2010 for selected advanced economies by examining two widely-used indicators: sovereign credit default swap (CDS) and relative asset swap (RAS) spreads. Cointegration analysis suggests the existence of an imperfect market arbitrage relationship between the cash (RAS) and the derivatives (CDS) markets, with price discovery taking place in the latter. Likewise, panel regressions aimed at uncovering the fundamental drivers of the two indicators show that the CDS market, although less liquid, has provided a better signal for sovereign credit risk during the period of the recent financial crisis.
