JCI Opens Weaker
The Composite Stock Price Index (JCI) moved lower on Monday morning, 6 April 2026, as market participants continued to monitor developments in the Middle East conflict between the United States (US) and Iran.
The JCI opened 25.22 points or 0.36% lower at 7,001.56. Meanwhile, the LQ45 index of 45 leading stocks fell 3.05 points or 0.43% to 711.53.
“The JCI is expected to potentially test the 6,900-7,000 level again,” said Ratna Lim, Head of Research at Phintraco Sekuritas, in her analysis in Jakarta on Monday.
From overseas, developments in the Middle East conflict will remain a key focus for market participants this week, as they assess prospects for de-escalation or prolonged escalation.
In addition, market participants will monitor updates on the reopening of the Strait of Hormuz. US President Donald Trump has warned Iran of a deadline to reopen the Strait of Hormuz on 6 April 2026, or face massive military escalation.
On the other hand, market participants will also watch the release of US economic data, including the FOMC Minutes from The Fed, inflation figures, ISM services PMI data, preliminary Michigan Sentiment readings, and Price Consumer Expenditure (PCE) inflation data.
Domestically, the implementation of new rules on data transparency for High Shareholding Concentration (HSC) could trigger short-term volatility due to overhang risks, particularly in low-liquidity stocks, although it will have positive long-term impacts through improved market transparency and liquidity.
Additionally, market participants will monitor various economic data releases, including foreign exchange reserves data on Wednesday, 8 April 2026, as well as consumer confidence index and automotive sales data on Friday, 10 April 2026.
If the war drags on, crude oil prices risk remaining high for an extended period. Consequently, the state budget deficit could widen if the government increases fuel subsidies without reallocating other budget items. “This could lead to capital outflows and continued rupiah depreciation,” said Ratna.
Asian regional stock exchanges this morning included the Nikkei index rising 559.51 points or 1.05% to 53,683.00, the Shanghai index falling 39.19 points or 1.00% to 3,880.10, the Hang Seng index declining 117.50 points or 0.70% to 25,116.53, and the Straits Times index gaining 11.92 points or 0.24% to 4,959.42.
