## History
### Colonial Era

Historically, the capital market has existed long before Indonesia's independence. Since the new era of the Dutch East Indies, the government began building plantations on a large scale in the Dutch East Indies. Sources of funds for building the plantation were obtained from the Dutch and other Europeans. Stock transactions in securities trading were first recorded in 1892, which was carried out by the Plantation Company in Batavia, namely Cultuur Maatschappij Goalpara, it was written that the company sold 400 shares at a price of 500 guilders per share outstanding. Four years later, Het Centrum also released a prospectus for the sale of shares with a value of up to 105 thousand guilders with a price per share of 100 guilders.
After careful preparation, the first capital market in Indonesia was finally established in Batavia (Jakarta) on 14 December 1912, which was named Vereniging voor de Effectenhandel or Stock Exchange and immediately started trading activities. The capital market at that time was established by the Dutch East Indies government for the benefit of the colonial government. The shares traded are shares or bonds of Dutch companies/plantations operating in Indonesia where the bonds issued by the provincial and municipal governments have company share certificates issued by the administrative office in the Netherlands and then the securities of other Dutch companies. The development of the capital market in Batavia is so fast that it attracted people from other cities.
The development and growth of the capital market did not go as expected, even during several periods of capital market activity experiencing a vacuum. This was caused by several factors such as the war which required the stock exchange to be closed, including in 1914-1918 the stock exchange was closed due to the occurrence of World War I. During World War II, the Stock Exchanges in Semarang and Surabaya had to be closed again in early 1939 and continued with the closing of the Stock Exchanges in Jakarta in 1942–1952. The transfer of power from the colonial government to the government of the Republic of Indonesia, and various conditions that caused the operation of the stock exchange to not run properly.

### Post-Colonial Era
#### Sukarno era

The Jakarta Stock Exchange was re-opened by President Sukarno on 3 June 1952. Until finally the existence of the Stock Exchange was again inactive when there was a nationalization program of Dutch companies from 1956 to 1977. The purpose of this re-opening of the stock exchange was to accommodate government bonds that had been issued in 1956, the previous year. The management of the stock exchange was then handed over to the money and securities trading union consisting of 3 banks and Bank Indonesia as honorary members. The development of this stock exchange is progressing well although the securities traded are generally bonds by Dutch companies and Indonesian government bonds through the Indonesian Development Bank. Through the State Industrial Bank in 1954, 1955 and 1958 bond sales increased. The occurrence of a power dispute between the Indonesian government and the Netherlands regarding West Irian meant that all Dutch businesses were nationalized through Act No. 86 of 1958. This dispute resulted in securities from the Netherlands no longer being traded on the Jakarta Stock Exchange.

#### New Order

The Government of the Republic of Indonesia reactivated the capital market in 1977, the Stock Exchange was inaugurated by President Soeharto on 10 August 1977.

The Surabaya Stock Exchange (BES) began operating in 1989 and is managed by a privately owned Limited Liability Company, namely the Surabaya Stock Exchange.
On 12 July 1992, which has been designated as the anniversary of the JSE, the JSE officially became a private company (privatization). BAPEPAM changed to Capital Market Supervisory Agency (formerly; Capital Market Implementing Agency). One year later on 21 December 1993, PT Pemeringkat Efek Indonesia (PEFINDO) was established. On 22 May 1995, the Jakarta Stock Exchange launched a trading automated system which was implemented using the JATS (Jakarta Automated Trading Systems) computer system. In the same year on 10 November, the Government of Indonesia issued Act Number 8 of 1995 on Capital Markets. This law came into effect in January 1996. The Indonesia Parallel Exchange was then merged with the Surabaya Stock Exchange. Then one year later, on 6 August 1996, the Indonesia Clearing and Guarantee Corporation (KPEI) was established. This was followed by the establishment of the Indonesian Central Securities Depository (KSEI) the following year, on 23 December 1997.

After the birth of the IDX, a trading suspension was enforced in 2008 and the Indonesian Stock Price Appraiser (PHEI) was formed in 2009.
