History
Originally opened in 1912 under the Dutch colonial government, it was re-opened in 1977 after several closures during World War I and World War II. After being reopened in 1977, the exchange was under the management of the newly created Capital Market Supervisory Agency (Badan Pengawas Pasar Modal, or Bapepam), which answered to the Ministry of Finance. Trading activity and market capitalization grew alongside the development of Indonesia's financial markets and private sector - highlighted by a major bull run in 1990. On July 13, 1992, the exchange was privatized under the ownership of Jakarta Exchange Inc. As a result, the functions of Bapepam changed to become the Capital Market Supervisory Agency. On March 22, 1995 JSX launched the Jakarta Automated Trading System (JATS). In September 2007, Jakarta Stock Exchange and Surabaya Stock Exchange merged and named Indonesian Stock Exchange by Indonesian Minister of Finance. The current location of the Indonesian Stock Exchange is located in the IDX building in the Sudirman Central Business District, South Jakarta, near the current site of the Pacific Place Jakarta.
