Jakarta, IDN Times – The Indonesian Composite Stock Price Index (IHSG) experienced a severe downturn this week, plummeting by over 8 percent, a slide that consequently impacted the nation’s stock market capitalization. This significant correction underscores a challenging period for investors on the Indonesia Stock Exchange (BEI).
According to Kautsar Primadi Nurahmad, Corporate Secretary of BEI, stock trading data from May 18-22, 2026, revealed a stark 8.35 percent correction in the IHSG’s performance. The index closed the week at 6,162.045, sharply down from its previous week’s position of 6,723.320. Nurahmad’s statement, released on Saturday (May 23, 2026), confirmed the extent of this market slump.
1. Market capitalization evaporated by Rp1,190 trillion
The pronounced dip in the IHSG throughout the week directly translated into a substantial erosion of the stock market’s capitalization on the BEI. The total market cap for the week was recorded at Rp10,635 trillion, representing a staggering loss of Rp1,190 trillion, or approximately 10.07 percent, compared to the previous week’s robust figure of Rp11,825 trillion.
2. Average daily transaction frequency decreased
Amidst the market’s decline, transaction metrics presented a mixed picture. The average daily transaction frequency on the BEI saw a 6.5 percent decrease, falling to 2.37 million transactions from 2.53 million the week prior. Interestingly, however, both the average daily transaction value and volume witnessed an uptick. The daily transaction value surged by 15.68 percent to Rp21.77 trillion, up from Rp18.82 trillion. Similarly, the average daily transaction volume increased by 2.53 percent, reaching 36.67 billion shares from 35.76 billion shares in the preceding week.
3. Foreign investors recorded a net sell of Rp41.63 trillion throughout 2026
Further contributing to the market’s pressure was significant activity from foreign investors. On Friday (May 22) alone, foreign investors registered a net sell of Rp309.52 billion. This recent activity compounded the year-to-date trend, pushing the total net sell by foreign investors throughout 2026 to a considerable Rp41.63 trillion. This figure marks an increase from the Rp37.61 trillion recorded just the previous week, indicating sustained capital outflow from the Indonesian stock market.

The Indonesian Composite Stock Price Index (IHSG) experienced a significant downturn, plummeting by 8.35% between May 18-22, 2026, to close at 6,162.045.
