The Jakarta Stock Exchange (now known as Indonesia Stock Exchange or IDX) holds significant importance in the business and finance world as it serves as the primary marketplace for trading securities and stocks, not only in Indonesia but the entire Southeast Asian region. Being the largest stock exchange in the country, it plays a critical role in the economic growth and development of Indonesia by providing individuals and corporate institutions with valuable investment opportunities, facilitating the capital raising processes for local businesses, and enhancing financial market transparency. Additionally, the IDX actively contributes to the global market and serves as an essential indicator of the Indonesian economy’s overall health, which is important for both domestic and international investors, as well as related stakeholders.


The Jakarta Stock Exchange (JSE), now known as the Indonesia Stock Exchange (IDX), serves an essential purpose in Indonesia’s financial and economic landscape. As the primary securities exchange in the country, the JSE provides an organized platform for the trading of stocks, bonds, and other financial instruments. By facilitating the exchange of financial securities, the JSE allows companies to raise capital through the issuance of shares, promotes secondary market trading, and acts as a vital component in the mobilization of financial resources for investment opportunities in Indonesia. This mechanism contributes to fostering economic growth, creating employment opportunities, and encouraging investment flows.

Moreover, the JSE’s role expands beyond enabling companies and investors to trade securities: it also helps maintain market integrity, transparency, and investor confidence. The exchange imposes rules and regulations that publicly traded companies must follow, ensuring that participants adhere to a high standard of corporate governance and information disclosure. The JSE achieves this by monitoring listed companies’ compliance with financial reporting and corporate actions.

Furthermore, the exchange enforces trading rules and guidelines that help prevent market manipulation and fraud, thereby safeguarding the interests of both retail and institutional investors. As a result of these measures, the JSE ultimately serves as a crucial platform to channel financial resources into the business sector and a foundation contributing to Indonesia’s overall economic dynamism and development.

2. The 2000 Jakarta Stock Exchange Bombing: On September 13, 2000, the Jakarta Stock Exchange building faced a terrorist bombing attack, which resulted in 15 casualties and several injured. The attack affected the stock market as trading was suspended for a few days. However, the bombing did not significantly disrupt the overall functioning of the market, and it resumed normal operations relatively quickly, showcasing the resilience and dedication of the Indonesian financial sector.

3. Initial Public Offerings (IPOs) on the Jakarta Stock Exchange: A notable example relating to the Indonesian stock market is the IPOs that have taken place on the exchange. Numerous Indonesian companies have chosen to go public on the Jakarta Stock Exchange to raise capital and expand their operations. For instance, one of the most prominent IPOs on the exchange was Bank Rakyat Indonesia (BRI) in 2003, which raised approximately $34.5 million.
