Results from calculating relative CDS spread deviations (model minus market spreads) initially reveal a price bubble in the European CDS market until the beginning of the financial crisis in mid-2007. From this point in time the gap narrows remarkably during the financial crisis and sovereign debt crisis period. Corresponding to these findings, the empirical analysis reveals a negative impact of sovereign risk on calculated CDS spread differentials indicating a spill-over effect between sovereign risk and bank risk and hence, a positive effect on bank-specific CDS pricing. Further analyses reveal that the perception of sovereign risk is not crisis- but country-dependent suggesting that bank-specific CDS market spreads may already include a premium to cover sovereign risk from PIIGS countries during the pre-crisis period in Europe. }}, author = {{Meine, Christian and Michalak, Tobias C. and Uhde, André}}, keywords = {{Sovereign risk, Structural credit risk models, bank-specific CDS pricing}}, publisher = {{Paderborn University}}, title = {{{Sovereign Risk and Bank-Specific CDS Pricing}}}, year = {{2012}}, } @inbook{36130, author = {{Kamp, Hermann}}, booktitle = {{Europa im 15.
