JCI Closes Down 0.61% on 31 March 2026
The Jakarta Composite Index (JCI) at the Indonesia Stock Exchange (IDX) was forced into negative territory at the close of trading on Tuesday (31/3/2026). A combination of pressure from international geopolitical tensions and domestic inflation concerns triggered investor selling actions.
According to IDX data, the JCI closed down by 43.45 points or 0.61% at 7,048.22. Meanwhile, the LQ45 index of top 45 stocks also experienced a slight correction of 1.68 points (0.23%) to 715.81.
Capital market observer Reydi Octa explained that the index’s movement today was heavily influenced by external and internal dynamics that prompted investors to take defensive steps.
From the international perspective, market participants continue to monitor the ongoing geopolitical tensions between the United States (US) and Iran. This tension directly impacts fluctuations in global energy prices, particularly the rise in crude oil prices, which triggers concerns over global logistics and production costs.
Domestically, investor anxiety is focused on the potential rise in inflation figures. Additionally, the fluctuating movement of the rupiah exchange rate adds pressure to the equity market. “Investors are tending towards defensive positions, evident from the rotation into energy and commodity stocks, and becoming very selective with large-cap stocks,” said Reydi.
Based on the IDX Sectoral Index, the majority of sectors ended in negative territory. The transportation and logistics sector recorded the deepest decline of up to 4.10%. This weakening was followed by the energy sector down 2.53% and the technology sector by 1.33%.
However, amid the index’s decline, three sectors managed to hold in positive territory:
Several stocks recorded significant gains (Top Gainers), including WEHA, POLA, CHEM, YPAS, and BANK. Conversely, the stocks with the deepest declines (Top Losers) included MDIY, GSMF, DATA, PPRE, and NZIA.
Market conditions in Asia generally trended lower. The Tokyo Nikkei index plunged 1.27% and the Shanghai Composite fell 0.80%. Only the Hong Kong Hang Seng managed a slight gain of 0.15% in afternoon trading.
The JCI remains under pressure from Middle East conflicts and the risk of rising oil prices, but it has potential support from the commodities sector and domestic economic stability.
