JCI Opens 0.28% Lower
The Jakarta Composite Index (JCI) opened in the red at the start of trading on Tuesday (27 October 2026). It opened at 5,357.97, down 15.12 points, or around 0.28%.
Trading volume stood at 4.94 million lots, with transactions valued at Rp168.18 billion. These figures are expected to change as the trading session progresses.
Indonesia’s financial markets will be influenced by a range of domestic and international factors. Wall Street’s gains are expected to provide a positive catalyst.
New policies from the Indonesia Stock Exchange (IDX) are also expected to boost investor confidence. Internationally, developments in the war and China’s economic data will drive markets today.
Investors are watching developments in the conflict. Saudi Arabia, Türkiye and Pakistan met Iran as oil prices eased.
Saudi Arabia, Türkiye and Pakistan met Iranian officials in Tehran on Monday in an effort to ease the Middle East conflict. The meeting took place amid intensifying Houthi attacks on Saudi Arabia and the threat of fresh strikes by the United States.
The four countries agreed to continue dialogue to strengthen cooperation on peace and security. Pakistan also proposed establishing a regional non-aggression network and finding a conflict resolution acceptable to both Washington and Tehran.
Tensions nevertheless remain high. US President Donald Trump has left open the possibility of attacking Iran again, while Tehran is demanding the lifting of port blockades and oil export sanctions before discussing its nuclear programme.
Meanwhile, Egypt’s parliament approved military support to help defend Saudi Arabia. The move strengthens regional defence cooperation amid a conflict disrupting shipping through the Strait of Hormuz and pushing up global energy prices.
Global crude oil prices fell on Monday (26 October 2026), amid hopes that the Middle East conflict could ease. However, attacks on Saudi Arabia and disruption to shipping continue to leave investors on edge.
Brent crude fell 0.8% to US$115.81 a barrel, while US West Texas Intermediate (WTI) crude dropped 1.46% to US$101.76 a barrel.
The pullback followed gains in both benchmarks the previous week. Brent rose 6% over the week, while WTI gained 2.3%.
Despite the decline, oil prices remain high as the risk of energy supply disruptions persists. Developments in the Middle East conflict will be an important factor in determining the next direction of prices.
Domestically, the Indonesia Stock Exchange (IDX) is preparing several new policies to tighten capital-market oversight. These include reducing share suspensions and freezing securities accounts suspected of violations, as well as strengthening investigations into suspicious transactions.
The IDX also plans to reduce its use of Unusual Market Activity (UMA) announcements as an initial step in its oversight process.
The committee assessing shares with high ownership concentration (High Shareholding Concentration, or HSC) is also being expanded to nine members, including five independent external representatives.
From 2 November 2026, HSC-category shares will also be excluded from the JCI calculation, alongside changes to the index review schedule. The measures are intended to strengthen transparency, safeguard trading liquidity and boost investor confidence in Indonesia’s capital market.
