Sovereign credit rating downgrades: an event study for European countries
| Resumo: | This master thesis studies the effects of sovereign credit rating downgrade announcements on credit default swap spreads. The analysis is done using an event study methodology to examine the reaction of credit default swap spreads variations to negative credit rating announcements. These variations are studied by year, country, event and globally across all events and spreads. Results show that we can exclude the hypothesis that CDS spreads are not affected by rating announcements. Besides this we can exclude the possibility that downgrades are anticipated by CDS markets. |
