JCI Opens Weaker, Here's Why

REPUBLIKA.CO.ID, JAKARTA — The Composite Stock Price Index (JCI) opened weaker on Thursday (9/4/2026) amid global geopolitical uncertainties. The JCI fell 40.75 points or 0.56% to the level of 7,238.46.

Weakness also occurred in the LQ45 index, which dropped 5.05 points or 0.69% to 728.57. Market pressure was triggered by market participants still monitoring the dynamics of the conflict between the United States and Iran.

Head of Research at Kiwoom Sekuritas Indonesia, Liza Camelia Suryanata, said that they see the next resistance for the JCI at 7,325. “If this level can also be breached, then the JCI will advance further towards the target of 7,600, which is the medium-term resistance,” she said on Thursday (9/4/2026).

From external factors, the two-week ceasefire agreement between the US and Iran has not yet been able to ease uncertainties. Iran even accused the US of violating several clauses, while tensions in Lebanon continue.

This situation has triggered volatility in global oil prices, with WTI and Brent oil at around $97 per barrel. Uncertainties in the Strait of Hormuz also add pressure on the energy market and investor sentiment.

Domestically, Indonesia’s foreign exchange reserves fell to $148.2 billion in March 2026 from the previous $151.9 billion. This decline reflects external pressures, including Bank Indonesia’s interventions to maintain rupiah stability.

In addition, two Pertamina tanker ships are still held in the Persian Gulf area due to technical and security issues. The government assures that energy supplies remain secure as import sources can be redirected to other countries.

Meanwhile, global bourses showed mixed movements. European and Wall Street markets strengthened in unison, while the majority of Asian bourses weakened in this morning’s trading.
