Global contagion of market sentiment during the US subprime crisis

Abstract

This paper investigates how global market sentiment propagates among the markets and how the interdependency through the propagation changes during the course of the US subprime crisis. We adopt a bivariate generalized autoregressive conditional heteroskedasticity (GARCH) model, and use a sample of eight global markets: Japan, Korea, Taiwan, Belgium, Germany, Netherlands, UK, and the Eurozone in our investigation. Our results identify that: (1) a long-run equilibrium relationship existed between market sentiment in the US and other major global markets during the subprime crisis period; (2) a global contagion of market sentiment occurred from the US market on September 15, 2008 to Japan, Korea, Belgium, Germany, Netherlands, and the Eurozone; and (3) the major global markets are all interrelated.
