Which Southeast Asian exchange began trading on 30 April 1975 as Thailand’s national securities market?

The Stock Exchange of Thailand began trading on 30 April 1975 as Thailand’s national securities market.

Thailand’s organized securities-market plans developed during the 1960s and early 1970s. The Securities Exchange of Thailand was established under the Securities Exchange of Thailand Act, and it commenced official trading in 1975. It was later renamed the Stock Exchange of Thailand, commonly abbreviated SET.

The SET provides a regulated marketplace for listed Thai securities and publishes important benchmarks such as the SET Index. It is based in Bangkok, Thailand’s political and financial center. The exchange is distinct from the Market for Alternative Investment, or mai, which serves smaller and growth-oriented companies within Thailand’s capital-market system.

The date 30 April 1975 refers to the start of trading, not merely the passage of the legislation that created the exchange. That distinction is useful when comparing the histories of national stock markets.
