Stock Exchange of Thailand — total market capitalisation
~THB 17–18T
The Stock Exchange of Thailand (SET) had a total market capitalisation of approximately THB 17–18 trillion at the close of 2023, making it the second-largest equity market in Southeast Asia by market cap after Indonesia (IDX). The SET Index tracks the performance of all common stocks listed on the main board; as of 2024 there are over 650 listed companies. Market cap fluctuates with baht exchange rates and global risk sentiment — the Thai bourse has historically been more sensitive to foreign portfolio flows than domestic institutional buying, given that foreign investors have owned 25–35% of the float in any given period. The Securities and Exchange Commission (SEC) of Thailand regulates listed entities and maintains a public disclosure database accessible via the SETSMART platform.
