The Stock Exchange of Thailand (SET) is negotiating with China to develop a new 60:40 index (60% China/HK/A-shares, 40% ASEAN/Thai stocks) targeting fund flows from Chinese institutional investors leveraging Beijing's policy liberalizing overseas investment. The index would underpin new ETF products and serve as a strategic tool to attract global institutional capital during Thailand's hosting of the IMF-World Bank Annual Meeting in October. This positions Thailand and ASEAN in the regional capital markets hierarchy while capitalizing on China's domestic capital-reallocation cycle.
