The article analyzes the existing relationship between two measures that estimate sovereign issuer’s solvency rate: ratings and Credit Default Swaps. Through the event study’s technique, we verify the impact of the rating changes announcements formulated by Standard & Poor’s from January 2004 to April 2013 on the euro-area sovereign Cds market. The analysis shows that downgrades have a significant effect on the Cds market, especially for speculative grade countries. Upgrades have a more limited impact only on the announcement day and on the following day. Outlooks are not relevant for investors, while negative reviews have an impact only on the days following the announcement.
L’articolo analizza la relazione esistente tra due misure che stimano il grado di solvibilità di uno Stato: i rating e i Credit default swap. Attraverso la tecnica dell’event study, abbiamo verificato l’impatto dell’annuncio delle variazioni di rating emesse da Standard & Poor’s dal gennaio 2004 all’aprile 2013 sul mercato dei Cds degli Stati dell’Area euro. L’analisi dimostra che i downgrade hanno un effetto significativo sul mercato dei Cds, in particolar modo per i Paesi che hanno un rating speculative grade. Gli upgrade causano un effetto maggiormente circoscritto alla data dell’annuncio. Gli outlook sembrano essere scarsamente rilevanti, mentre le review negative hanno un impatto solo nei giorni seguenti all’annuncio.

Abstract
The article analyzes the existing relationship between two measures that estimate sovereign issuer’s solvency rate: ratings and Credit Default Swaps. Through the event study’s technique, we verify the impact of the rating changes announcements formulated by Standard & Poor’s from January 2004 to April 2013 on the euro-area sovereign Cds market. The analysis shows that downgrades have a significant effect on the Cds market, especially for speculative grade countries. Upgrades have a more limited impact only on the announcement day and on the following day. Outlooks are not relevant for investors, while negative reviews have an impact only on the days following the announcement.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
