This article examines the Credit Default Swap (CDS) spread index for three sectors, banking, financial services and insurance, in the short and long run. In the long run, the results show that the index of the insurance sector which sells the long term CDS contracts has the highest adjustment, while the banking sector is not error correcting. In the short run, although the insurance sector CDS spread index has general predictive power of all sector CDS spreads, the evidence suggests that the banking sector particularly leads the financial services and this in turn leads the insurance sector, implying a leading sector CDS pricing role for the banking spreads in the short run. The short run sensitivity Generalized Impulse Response Function (GIRF) and Generalized Variance Decomposition (GVDC) analyses also demonstrate that the sectors credit risk responds more to credit events in the banking sector than in the other two sectors other than their own over a 50 day horizon. However, the lowest cross sector CDS shock impacts in the short run come from the insurance sector. These results are useful for regulators wishing to embark on new regulations of these financial institutions such as Basel III.
