IDX Reports Strong Growth as Investor Numbers Hit 18.6 Million
Introduction
The Indonesia Stock Exchange (IDX) is experiencing remarkable growth, with the number of investors reaching a significant milestone of 18.6 million. This surge in investor participation was highlighted during a workshop focused on non-stock products, which took place in Tawangmangu, Karanganyar Regency, Central Java, on October 2, 2025. Jeffrey Hendrik, the IDX Director of Development, shared insights into the current state of the market and its trajectory.
Market Performance Amid Global Volatility
During the workshop, Hendrik provided an overview of the IDX’s performance, particularly in light of recent global economic challenges. He noted that following the Eid al-Fitr holiday in April 2025, the market experienced a downturn triggered by the announcement of reciprocal tariffs by U.S. President Donald Trump. This announcement led to increased volatility across stock markets worldwide.
Despite this setback, the Indonesian capital market rebounded strongly throughout 2025, achieving its highest historical index and record market capitalization. By early August 2025, the IDX’s market capitalization had reached an impressive Rp13,400 trillion (approximately US$900 billion), positioning Indonesia among the top 20 largest stock exchanges globally. Notably, the IDX ranks as the 11th largest stock exchange in terms of trading activities.
Growth in Investor Participation
The growth in the number of investors has been particularly noteworthy. As of October 1, 2025, Hendrik reported that there were 3.7 million new investors added in just one year, bringing the total number of investors in the capital market to 18.6 million. This figure represents a significant increase from the previous year, when the IDX welcomed 2.7 million new investors.
Among the 18.6 million investors, approximately 7.7 million are actively engaged in stock trading. Hendrik indicated that daily transactions are conducted by around 200 investors, while 1.6 million investors engage in trading on an annual basis. This diversity in investor activity underscores the growing interest in the Indonesian capital market.
Meeting Diverse Investment Needs
Hendrik emphasized that the IDX recognizes the varied investment needs of its growing investor base. He pointed out that while some investors are experienced and capable of navigating the stock market effectively, others may have limited investment resources despite their experience. To cater to these diverse needs, the IDX is actively working to expand the range of investment products available.
The exchange is set to introduce several new financial instruments, including exchange-traded funds (ETFs), structured warrants, carbon exchanges, and short selling options. Additionally, the IDX plans to launch liquidity providers and repurchase agreements (repos) in the near future. This expansion aims to enhance accessibility and provide a wider array of investment opportunities for all investor segments.
Regional Growth and Transaction Trends
In a regional context, Muhammad Wira Adibrata, the Head of IDX Central Java 2, reported positive trends in the Solo Raya working area. Monthly transactions in this region have increased from approximately Rp3 trillion to Rp5 trillion. Furthermore, the average number of new investors has risen significantly, with the region recording an average of 5,000 new investors per month over the last three months, compared to the previous average of 2,500 to 3,000 new investors.
This growth in investor numbers and transaction volume reflects a broader trend of increasing engagement with the stock market in Indonesia. The IDX’s initiatives to expand its product offerings and improve accessibility are likely to continue driving this momentum.
Conclusion
The IDX’s strong growth trajectory and the remarkable increase in investor participation signal a positive outlook for the Indonesian capital market. As the exchange continues to innovate and adapt to the needs of a diverse investor base, it is well-positioned to maintain its status as a leading financial hub in Southeast Asia. The introduction of new investment products and a commitment to enhancing market accessibility will likely further stimulate investor interest and participation in the years to come.
