Jakarta, CNBC Indonesia — The Composite Stock Price Index (IHSG) in the first session today, Tuesday (31/3/2026), fell 37.89 points or -0.53% to the level of 7,053.78. A total of 282 stocks rose, 403 fell, and 273 were unchanged.

The transaction value reached Rp 7.46 trillion, involving 14.55 billion shares in 999,700 transactions. Market capitalisation was also eroded to Rp 12.417 trillion.

The IHSG’s volatility throughout the session was quite high. The IHSG opened trading in the green zone and even rose 0.8% at one point. However, about an hour after opening, the IHSG plunged into the red zone.

Quoting Refinitiv, almost all sectors were in the red zone. Utilities and energy led the correction with declines of 3.45% and 1.67%, respectively.

Meanwhile, Barito Renewables Energy (BREN) became the main drag with a weight of -8.33 points. This was followed by Dian Swastatika Sentosa (DSSA) at -6.55 points and Astra International (ASII) at -6.14 points.

Entering today’s trading, domestic financial market players will be watching several important external sentiments. The main focus comes from developments in the Middle East war, which continues to pressure energy prices, the strengthening US dollar index, and the release of labour data from the United States (US) and Japan.

The war in the Middle East has yet to show signs of abating. The conflict, now in its fifth week, remains the primary source of global market anxiety, particularly due to disruptions in the Strait of Hormuz that have not been fully resolved. US President Donald Trump warned Iran on Monday to open the route, amid uncertainty over diplomatic talks and high military tensions.

For the markets, developments in this war are crucial because the Strait of Hormuz is one of the world’s vital energy trade routes.

Prolonged disruptions in the region continue to raise concerns over crude oil and gas supplies, especially for Asia, which is heavily reliant on energy flows from the Middle East. As long as this route is not fully restored, markets will continue to price in a high risk premium for energy prices.

This pressure is directly reflected in global oil prices. In Monday’s trading (30/3/2026), Brent prices moved in the range of US$114-116 per barrel, while West Texas Intermediate (WTI) was around US$100-102 per barrel, indicating that energy volatility remains very high. This rise shows that the market still views the war as a serious threat to global supplies.

Meanwhile, domestically, the Indonesian government will announce a series of policies aimed at responding to the economic impacts of the US and Israel war with Iran.

Secretary of the Coordinating Ministry for Economic Affairs Susiwijono Moegiarso said the policy announcement will be made at 19:00 WIB today, Tuesday (31/3/2026).

“All policies related to mitigating risks from global dynamics (WFH, Budget Adjustments, B-50, etc.) will be announced tomorrow,” Susiwijono said in a written statement on Monday (30/3/2026).

As is known, several neighbouring countries of Indonesia have already announced policies in response to the economic turmoil triggered by the US-Israel war with Iran. The war began with a US attack under President Donald Trump’s administration on Iran at the end of February 2026.

PT Pertamina will also release prices for non-subsidised fuels effective from 1 April today. This routine announcement will be issued around 21:00-22:00 WIB.

As is known, Pertamina adjusted fuel oil (BBM) prices across Indonesia effective 1 March 2026.

Pertamina’s fuel products at petrol stations, where the price of RON 92 or Pertamax fuel rose to Rp 12,300 per litre from Rp 11,800 per litre in February. Then Pertamax Green or RON 95 became Rp 12,900 per litre from the previous Rp 12,450 per litre.

Pertamax Turbo also rose to Rp 13,100 per litre from the previous Rp 12,700 per litre. Dexlite became Rp 14,200 per litre from the previous Rp 13,250 per litre. And Pertamina Dex became Rp 14,500 per litre from Rp 13,500 per litre.

Observed prices for Pertalite remain at Rp 10,000 per litre and subsidised diesel at Rp 6,800 per litre.
