JCI Falls 0.42% to 5,911 at Midday Break
Jakarta, CNBC Indonesia — The Jakarta Composite Index (JCI) managed to pare its losses significantly, although it remained in negative territory during trading on Tuesday (13 October 2026). At the end of the first session, the index stood at 5,911.46, down 24.68 points, or 0.42%.
The decline was considerably smaller than at the start of the session, when the JCI briefly fell by more than 1.7%.
Trading volume was 217.03 million lots, with transactions worth Rp5,608.26 billion.
The JCI opened at 5,914.98 but came under selling pressure in the opening minutes. It briefly touched the day’s low of 5,828.68 at around 9.30am Western Indonesian Time, when losses were at their deepest. The trend then reversed. From its low, the JCI rose by about 82.78 points, or roughly 1.4%, bringing it close to its opening level.
The recovery was gradual. The JCI began edging up from around 5,830 shortly before 10am, then moved above 5,900. For most of the session, the index traded sideways between 5,890 and 5,915. Towards midday, it continued to gain, reaching a high of 5,927.13 before slipping slightly to 5,911.46 in the latest data.
After taking a battering in the previous day’s trading, Indonesia’s financial markets were likely to face a range of pressures on Tuesday.
Uncertainty surrounding MSCI, the escalating war and the International Monetary Fund (IMF) meeting were among the factors expected to influence markets. The day’s key market factors included:
- War developments: Houthis bombard Saudi Arabia with missiles and drones
Saudi Arabia faced further missile and drone attacks by Yemen’s Houthi group on Monday (12 October 2026). Riyadh International Airport remained closed after a missile strike on Saturday killed 13 people and injured more than 300.
The Saudi-led coalition reported the threat of further attacks amid an escalation of the conflict, which has expanded from the US-Iran war. The Houthis have also continued targeting Saudi oil facilities and infrastructure, fuelling concerns about the security of global energy supplies.
Saudi Arabia has once again become involved in the Yemen conflict in an effort to pressure the Houthis near the Bab el-Mandeb Strait, a strategic shipping route for oil trade. However, forces backed by Riyadh continue to face resistance on several fronts.
Amid the conflict, Iran offered to mediate between the Houthis and Saudi Arabia. The United Arab Emirates, meanwhile, called for stronger security and defence cooperation among Gulf states.
US President Donald Trump had previously said Washington was considering joining Saudi Arabia in attacking the Houthis. So far, however, there have been no signs of a US military operation.
- Oil prices rise as dollar index surges
Global oil prices rose by nearly US$2 a barrel in trading on Monday (12 October 2026). Attacks on Saudi Arabia stoked concerns about supply disruptions, outweighing the prospect of additional supplies after US President Donald Trump announced increased Russian diesel exports and a Russia-Ukraine ceasefire on attacks against energy infrastructure.
Brent crude futures settled US$1.93 higher, up 1.8%, at US$106.65 a barrel, their highest level since 15 September. US West Texas Intermediate (WTI) crude rose US$1.89, or 2%, to US$93.74 a barrel.
- MSCI concerns
Phintraco Sekuritas analyst Desy Erawati said sentiment surrounding Morgan Stanley Capital International (MSCI) continued to weigh on the JCI. Markets are watching the risk of Indonesia being downgraded from emerging-market to frontier-market status, as well as the prospect that the freeze on certain MSCI index changes could be lifted, which is projected for the second half of 2027.
“Market concerns are still related to MSCI,” Desy told CNBC Indonesia on Monday (12 October 2026).
