Financial Crisis and Intertemporal Linkages Across the ASEAN-5 Stock Markets

The stock indices of five ASEAN countries, namely, Singapore, Malaysia, Indonesia, Thailand and the Philippines have experienced a structural change after mid-1997 due to the Asian financial crisis, and another shift slightly more than a year later when the markets rebounded. Contemporaneous correlation in stock returns is the strongest and Indonesia leads the movements of the other indices during the crisis. The relative influence of foreign shocks is much more felt during the crisis, as seen in the stronger and longer horizon of responses of all the markets. The stock indices are cointegrated before, but not during the crisis. Price feedbacks between the larger markets of Singapore, Malaysia and Indonesia that existed before the crisis disappear once the crisis is over. Short-run linkages of Malaysia with the other markets have weakened after the crisis. With an increase in the degree of exogeneity of its stock market, contemporaneous co-movements with the other markets have reduced and the causal relationships no longer exist.JEL Classification: G15, F30An earlier draft of this paper was presented at the 11th Annual Conference on Pacific Basin Finance, Economics & Accounting held in Taipei.
