JCI Falls 2% at Midday as Analysts Identify Market Pressures
Jakarta, CNBC Indonesia – The Indonesia Stock Exchange’s (IDX) Jakarta Composite Index (JCI) closed Monday’s (12 October 2026) first trading session down 117.98 points, or 1.94%, at 5,975. At its intraday low, the index had fallen 2% to 5,971.
Several analysts highlighted pressures on the domestic equity market, ranging from uncertainty over global index policy to international macroeconomic sentiment.
The decline came as all sectors on the IDX weakened. Energy recorded the steepest fall, down 3.57%, followed by infrastructure, which lost 3.33%, and basic materials, which fell 2.77%.
Industrials declined 2.39%, consumer staples fell 1.74% and transport was down 1.81%. Consumer discretionary lost 0.49%, property fell 0.86%, financials declined 0.96%, and technology and healthcare each dropped 0.80%.
Phintraco Sekuritas analyst Desy Erawati said sentiment surrounding Morgan Stanley Capital International (MSCI) remained a key concern for market participants. Investors were monitoring the risk of Indonesia being downgraded to frontier-market status, as well as the prospect of MSCI lifting its freeze on certain index changes, which is projected for the second half of 2027.
“Market issues are still related to MSCI,” Desy told CNBC Indonesia on Monday (12 October 2026).
MSCI previously froze increases to the foreign inclusion factor (FIF) and number of shares (NOS), as well as the addition of new stocks and upgrades to stocks’ status in its indices. The policy is due to be reviewed ahead of the November 2026 index review, with MSCI’s announcement expected at the end of October.
Separately, BRI Danareksa Sekuritas said the JCI’s early-session weakness came as investors awaited inflation data from the United States and China. Global sentiment this week is also being weighed down by escalating geopolitical tensions in the Middle East and meetings of the International Monetary Fund (IMF) and World Bank from 12 to 18 October 2026.
On Wednesday (14 October 2026), investors will focus on the release of US and Chinese inflation figures, as well as China’s trade balance. The data could affect interest-rate expectations, movements in the US dollar and rupiah, and the outlook for commodity demand.
Investors will also watch speeches by several US Federal Reserve (Fed) officials from 14 to 16 October 2026. Their remarks will be scrutinised for clues about the future direction of US monetary policy.
BRI Danareksa Sekuritas said the JCI’s short-term outlook was tilted to the downside amid selling pressure and geopolitical uncertainty. US inflation above expectations could strengthen the dollar, put pressure on the rupiah and trigger further foreign fund outflows from the domestic equity market.
Meanwhile, developments in China’s economic data could affect Indonesia’s export outlook and the performance of commodity-related shares. Market participants will therefore monitor global sentiment and clarity on MSCI policy to gauge the JCI’s next direction.
