The story
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 Department 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 13 July 1992, the exchange was privatised under the ownership of Jakarta Exchange Inc. As a result, the functions of Bapepam changed to become the Capital Market Supervisory Agency. On 22 March 1995, JSX launched the Jakarta Automated Trading System (JATS). In September 2007, Jakarta Stock Exchange and Surabaya Stock Exchange merged to form the Indonesian Stock Exchange by the Indonesian Minister of Finance.
