Abstract: We analyze the cross-border propagation of systemic risk in the international sovereign debt market. Using daily data on CDS spreads for 67 sovereign borrowers from 2002 to 2013 we define sovereign credit events as those in which the spread widens by more than 99.9% of all spread changes within regions. We find a total of 89 such credit events, most of them taking place after 2007. We analyze contagion by studying the immediate effects of these events on CDS spreads of other sovereigns within the region and in the rest of the world. Although a few events had effects that were global in scope, we find that such "fast and furious" contagion has been by and large a regional phenomenon. To analyze "slow burn" spillover effects, we extract the first principal component of CDS spread changes to identify a global sovereign risk factor. The corresponding loadings on this factor then serve to measure the sensitivity of individual sovereign CDS spreads to the global factor. We allow these loadings to vary over time and interpret them as measures of vulnerability to global systemic risk. We find that the global "slow-burn" spillover of credit events works through the global risk factor rather than through sovereign obligors' systemic vulnerabilities. While the global factor and regional vulnerabilities are both influenced by investors' risk appetites, such vulnerabilities also depend on economic fundamentals, including the sovereign's level of government debt.
