The Indonesia Stock Exchange (IDX), also known as BEI, reported a substantial 8.35 percent correction in its benchmark Composite Stock Price Index (IHSG) during the week of May 18-22, 2026. This notable downturn signals a challenging period for the nation’s stock market.
Despite the overall market dip, Kautsar Primadi Nurrahmad, Corporate Secretary of the IDX, highlighted areas of resilience. The average daily transaction value, for example, experienced a significant surge of 15.68 percent, climbing to Rp 21.77 trillion from Rp 18.82 trillion in the preceding week.
Further reflecting active trading despite the price decline, the average daily transaction volume on the IDX also increased by 2.53 percent, reaching 36.67 billion shares compared to 35.76 billion shares recorded the week prior.
Conversely, the average daily transaction frequency saw a decline, dropping by 6.5 percent to 2.37 million transactions from 2.53 million transactions last week. This suggests fewer individual trading events, even as total value and volume rose.
Kautsar reiterated the week’s performance, stating in an official release quoted on Saturday (May 23), “The movement of the IHSG throughout the week corrected by 8.35 percent, closing at 6,162.045, down from its position of 6,723.320 in the prior week.” This sharp drop underscores the prevailing cautious sentiment among investors.
Compounding the market’s challenges, the IDX’s market capitalization plummeted by 10.07 percent, shrinking to Rp 10,635 trillion from an impressive Rp 11,825 trillion recorded just a week earlier.
Adding to the selling pressure, foreign investors registered a net sell of Rp 309.52 billion on Friday, May 22. This brings their cumulative year-to-date net sell for 2026 to a significant Rp 41.63 trillion, indicating a sustained outflow of international capital from the Indonesian stock market.
Amidst these market fluctuations, the IDX received a significant visit on Tuesday, May 19. Sufmi Dasco Ahmad, Deputy Speaker of the Indonesian House of Representatives (DPR RI), was welcomed at the BEI Building. He was accompanied by several key figures: Friderica Widyasari Dewi, Chairman of the Board of Commissioners of the Financial Services Authority (OJK); Rosan Roeslani, Chief Executive Officer of Danantara; and Dony Oskaria, Chief Operating Officer of Danantara.
Kautsar emphasized the strategic importance of this visit, explaining, “The visit served as a crucial form of support for strengthening investor confidence and ensuring stability within the Indonesian capital market.”
During the engagement, Kautsar further noted that Mr. Dasco conveyed a strong sense of optimism regarding the long-term prospects of the Indonesian capital market, even in the face of the current IHSG pressures. This reassuring stance aims to bolster confidence among market participants despite recent declines.
