The spread of the global financial crisis of 2008/2009 was rapid, and impacted the functioning and the performance of financial markets. Due to the importance of this phenomenon, this study aims to explain the impact of the crisis on stock market behavior and interdependence through the study of the intraday volatility transmission. This paper investigates the patterns of linkage dynamics among three European stock markets—France, Germany, and the UK—during the global financial crisis, by analyzing the intraday dynamics of linkages among these markets during both calm and turmoil phases. We apply a VAR-EGARCH (Vector Autoregressive Exponential General Autoregressive Conditional Heteroscedasticity) framework to high frequency five-minute intraday returns on selected representative stock indices. We find evidence that interrelationship among European markets increased substantially during the period of crisis, pointing to an amplification of spillovers. In addition, during this period, French and UK markets herded around German market, possibly explained by behavior factors influencing the stock markets on or near dates of extreme events. Germany was identified as the hub of financial and economic activity in Europe during the period of study. These findings have important implications for both policymakers and investors by contributing to better understanding the transmission of financial shocks in Europe.

We calculate returns using the equation Ri,t = 100 × (lnPi,t – lnPi,t-1) where Ri,t is the return for stock market index i at time t, ln(Pi,t) is the log of stock price at time t, and ln(Pi,t-1) is the log of the laged value of the stock price at time t. Following Andersen et al. (2000), we delete the return inverval 9.00？9.05 CET to avoid statistical inference.

We assume that: E(Rt,n) = 0, E(Rt,n , Rs,m) = 0 and that the variance and covariance of squared returns exist and are finite. The continuously compounded daily squared returns may be decomposed as: Rt 2 = (∑Rt,n2).
