We investigate the relationship between credit rating events and credit default swap spreads for EU countries around the Subprime and European Debt Crises. Using event studies and OLS regressions we analyse the behavior of CDS spreads before, around and after credit rating events. Our results indicate that CDS spreads anticipate positive rating events as early as 2-3 months before the event however the anticipation for negative events is only 1-2 months prior; in addition we also observe announcement and post announcement effects in some instances. We also find that the behavior of CDS spreads and credit rating events has undergone a significant change after the crisis period. On similar lines, using logit and multinomial logit regressions we find that a change in CDS spreads are effective in predicting forthcoming credit rating events.

This paper examines the spillover effects of sovereign rating news on European financial markets during the period 2007-2010. Our main finding is that sovereign rating downgrades have statistically and economically significant spillover effects both across countries and financial markets. The sign and magnitude of the spillover effects depend both on the type of announcements, the source country experiencing the downgrade and the rating agency from which the announcements originates. However, we also find evidence that downgrades to near speculative grade ratings for relatively large economies such as Greece have a systematic spillover effects across Euro zone countries. Rating-based triggers used in banking regulation, CDS contracts, and investment mandates may help explain these results.

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.

The financial difficulties experienced by Greece since 2009 serve as a reminder that countries (i.e., sovereigns) may default on their debt. Many observers considered the financial turmoil was behind us because major advanced countries had adopted stimulus packages to prevent banks from going bankrupt. However, there are rising doubts about the creditworthiness of several advanced countries that participated in the bailouts. In this uncertain context, it is particularly crucial to be knowledgeable about sovereign ratings. This book provides the necessary broad overview, which will be of interest to both economists and investors alike. Chapter 1 presents the main issues that are addressed in this book. Chapters 2, 3, and 4 provide the key notions to understand sovereign ratings. Chapter 2 presents an overview of sovereign rating activity since the first such ratings were assigned in 1918. Chapter 3 analyzes the meaning of sovereign ratings and the significance of rating scales; it also describes the refinement of credit rating policies and tools. Chapter 4 focuses on the sovereign rating process. Chapters 5 and 6 open the black box of sovereign ratings. Chapter 5 compares sovereign rating methodologies in the interwar years with those in the modern era. After examining how rating agencies have amended their methodologies since the 1990s, Chapter 6 scrutinizes rating disagreements between credit rating agencies (CRAs). Chapters 7 and 8 measure the performances of sovereign ratings by computing default rates and accuracy ratios: Chapter 7 looks at the interwar years and Chapter 8 at the modern era. The two chapters assess which CRA assigns the most accurate ratings during the respective periods. Chapters 9 and 10 compare the perception of sovereign risk by the CRAs and market participants. Chapter 9 focuses on the relation between JP Morgan Emerging Markets Bond Index Global spreads and emerging countries’ sovereign ratings for the period 1993–2007. Chapter 10 compares the eurozone members’ sovereign ratings with Credit Default Swap-Implied Ratings (CDS-IRs) during the Greek debt crisis of November 2009–May 2010.

The global financial crisis saw many Eurozone countries bearing excessive public debt. This led the government bond yields of some peripheral countries to rise sharply, resulting in the outbreak of the European sovereign debt crisis. The debt crisis is characterized by its immediate spread from Greece, the country of origin, to its neighbouring countries and the connection between the Eurozone banking sector and the public sector debt. Addressing these interesting features, this book sheds light on the impacts of the crisis on various financial markets in Europe. This book is among the first to conduct a thorough empirical analysis of the European sovereign debt crisis. It analyses, using advanced econometric methodologies, why the crisis escalated so prominently, having significant impacts on a wide range of financial markets, and was not just limited to government bond markets. The book also allows one to understand the consequences and the overall impact of such a debt crisis, enabling investors and policymakers to formulate diversification strategies, and create suitable regulatory frameworks.
