AbstractSince the onset of the eurozone sovereign debt crisis, credit risk spreads in Europe have diverged. Despite this divergence, credit risk comoves strongly within certain country groups such as the eurozone periphery. We seek to answer what the determinants of the observed pattern of credit risk co-movements are and whether and during which periods sovereign debt markets have been subject to contagion.We proceed in three steps. First, we apply dynamic conditional correlations from a multivariate GARCH model to sovereign CDS spreads of 17 countries over the period 2008 to 2012. Second, we separate periods of simple interdependence fromcontagion. Third, we analyze the determinants behind credit risk co-movements and the role of contagion using regression analysis. Our results reveal a high degree of co-movements in sovereign credit risk, especially for eurozone countries during the sovereign debt crisis. We find strong evidence for both fundamentals and nonfundamentals based contagion. Similarities in economic fundamentals, cross-country linkages in banking and common market sentiment play a significant role.Keywords: Sovereign debt crisis, financial contagion, banking market integration JEL Classification: F30, F65, G01, G15 * We are grateful to Claudia Buch and Elena Carletti for continuous advice and encouragement. Furthermore, we would like to thank Mascia Bedendo, Martin Biewen, Elena Dumitrescu, Carlo Favero, Peter Hansen, Massimiliano Marcellino, Giovanni Piersanti, Esteban Prieto and Saverio Simonelli for many helpful comments as well as the Bank for International Settlements for kindly providing data. The paper has also benefited from comments by seminar participants at the This divergence can be explained by worsened fiscal positions following government interventions in the banking sector during the financial crisis as well as fiscal stimulus packages. At the same time, a high degree of financial integration in eurozone countries due to cross-border activities of banks and the existence of a common currency gave rise to interdependencies. In how far these interdependencies translate into volatile market reactions across countries and cause co-movements in sovereign credit risk is, however, hardly understood.Our objective is to take a closer look at the pattern of sovereign credit risk across European countries. To do so, we ask the following questions: First, does sovereign credit risk comove across ...
