Similarly, the average daily transaction volume saw a decline of 21.09 percent, dropping to 37.24 billion shares from 47.19 billion shares in the preceding week.

Despite the mixed trading performance, the IDX underscored a significant surge in the number of Indonesian capital market investors. As of the end of August 2025, the total number of investors surpassed an impressive 18 million Single Investor Identification (SID) holders, demonstrating continued robust growth in market participation.
In line with its mandate, the IDX hosted several key events during the past week. On Monday, September 1, 2025, the IDX, in collaboration with the Financial Services Authority (OJK) and the Coordinating Ministry for Economic Affairs, organized a press conference titled “Indonesian Capital Market Stability” at the IDX Main Hall. During this event, Coordinating Minister for Economic Affairs, Airlangga Hartarto, confidently affirmed the enduring strength and solidity of Indonesia’s economic fundamentals.
Minister Hartarto further emphasized the strategic role of the Indonesian capital market as a crucial source for development financing and a vital platform for public investment. He reiterated the government’s unwavering commitment, alongside capital market authorities, to preserving market stability. This commitment aims to ensure the market continues its significant contribution to inclusive and sustainable national economic growth.
Building on these initiatives, Wednesday, September 3, 2025, marked another pivotal moment as IDX President Director, Iman Rachman, held a meeting with the General Chairman of PBNU, KH Yahya Cholil Staquf (Gus Yahya). This encounter was hailed as a strategic opportunity to further the development of Indonesia’s burgeoning Sharia capital market.
The establishment of close synergy, particularly amid domestic demonstrations from late August to early September 2025, is deemed essential for fostering a conducive economic environment. The unified support from the government and prominent community organizations like PBNU for the capital market is anticipated to significantly broaden financial inclusion, accelerate the growth of the Sharia capital market, and reinforce the market’s indispensable role in driving national economic development.
