This integration is the third degree of the economic integration which is so-called common market.It will allow free mobilization of supplies, product, services and labour within the member countries. According to optimum currency area, the participant countries sharing a single currency need to posses synchronicity of the economic variables. This article explores the synchronicity of capital variables in ASEAN countries using data from securities price index of 5 ASEAN member countries: Indonesia, Malaysia, the Philippines, Singapore and Thailand from January 4, 2010 to October 31, 2013. Moreover, the conintegration as well as the impulse response function were also calculated and analyzed. The findings reveal that the securities price index of the 5 ASEAN member countries are cointegrated. Furthermore, the analysis of the impulse response function also turns out to be synchronous. This study supports the possibility of setting up the ASEAN securities market to raise funding for business sectors in the ASEAN countries and to upgrade the stock market of the ASEAN countries to be internationally competitive.
