      This study investigates the impact of the 2008 global financial crisis on interest rate spreads across OECD countries, using a number of panel methodological approaches, over the 1990–2015 period. We examine the differential impact of the global financial crisis on interest rate spreads by dividing the sample period into two, i.e. the period prior to and after the crisis. Having identified and estimated the impact of a number of drivers on interest rate spreads, the findings document that after the 2008 financial crisis, the sensitivity of spreads to its determinants turn out to be statistically significant and incorporate credit risk to a greater extent. The findings survive a number of robustness checks. The policy implications of the empirical findings are also discussed.

      This study investigates whether contagion occurred during the recent global financial crisis across EU and US financial markets. The methodology used to test for contagion is the Forbes and Rigobon cross-correlation test, the Li and Zhu non-parametric test, the Fry et al. coskewness test and the Hsiao cokurtosis and covolatility tests. These tests are applied to a set of bank sector CDS, insurance sector CDS, sovereign bonds, equity and volatility indices. The findings indicate significant evidence of contagion, especially through the channels of higher order moments.
