The recent financial crisis initiated from the subprime mortgage incident has resulted with series of credit default events and global economic recession. Credit derivatives have become a key financial product in capital market. The relationship between the two is significant to academics and industries in understanding dynamics of financial market. This study explores the impacts on Credit Default Swaps (CDS) from key events of financial crisis with method of event study and cross-sectional regression. The empirical findings show that shocks of CDS spread significantly coincide with major credit events, and the magnitudes of shocks are greater for negative events than for positive events. The CDS spreads of financial industry jump prior to event occurrences, and the outcome suggest that trends of CDS spread can be used to predict major credit defaults. The reactions among CDS spreads have significant positive contagion effects for financial industry and, only in the beginning of crisis, negative competitive effects for non-financial industry. When series of credit events continue, such competitive effects turn into contagion effects, and the levels of impacts vary with similarities among industries. The magnitudes of the contagion effects also change across samples with different firm characteristics. |
