The Analysis of Capital Market Integration in ASEAN Region by Using the Ogarch Approach

Capital market integration is a topic that attracts a lot of research interests in regional andinternational capital markets.

This study investigated the capitalmarkets integration in ASEAN by using the Orthogonal Generalized Autoregressive ConditionalHeteroscedasticity (OGARCH) method which could provide the degree of integrationquantitatively. Capital markets studied were Indonesia Stock Exchange, KualaLumpur Stock Exchange, Thailand Stock Exchange, Singapore Stock Exchange and PhilippinesStock Exchange during period of January 2001 – December 2016.

This study also found that IndonesiaStock Exchange, Kuala Lumpur Stock Exchange, Stock Exchange Thailand, andSingapore Stock Exchange were integrated but Philippines Stock Exchange was not.
