    Abstract: This paper examines whether the introduction of Chinese stock index futures had an impact on the volatility of the underlying spot market. To this end, we estimate several Generalized Auto-Regressive Conditional Heteroscedasticity (GARCH) models and compare our findings for mainland China with Chinese index futures traded in Singapore and Hong Kong. Our results indicate that Chinese index futures decrease spot market volatility in all three spot markets considered. In contrast, we do not obtain the same results for the companion index futures markets in Hong Kong and Singapore. China’s stock market is relatively young and largely dominated by private retail investors. Nevertheless, our evidence is favorable to the stabilization hypothesis usually confirmed in mature markets.

    Abstract: We provide a new approach to understanding systemic risk by analysing complex linkages in finance and insurance sectors. The analysis is achieved by using a recently proposed method for quantifying causal coupling strength, which identifies the existence of causal dependencies between two components of a multivariate time series and assesses the strength of their association by defining a meaningful coupling strength. The measure of association is general, causal and lag-specific, reflecting a well interpretable notion of coupling strength and is pratically computable. A comprehensive analysis of the feasibility of this approach is provided via simulated and real data
