Breaking News! IHSG Opens Down 1% This Morning
Jakarta, CNBC Indonesia — The Composite Stock Price Index (IHSG) opened sharply down 1% this morning, on Monday (6/4/2026). The index fell to the level of 6,945.97, or eroded by 71.81 points.
A total of 345 stocks declined, 165 rose, and 448 remained unchanged. The transaction value reached Rp355.2 billion, involving 633.4 million shares in 78,260 transactions.
Market capitalisation was also eroded to Rp12,112 trillion.
The IHSG is still overshadowed by several global and domestic sentiments. In the latest developments, US President Donald Trump has posted on social media full of abusive language, in which he threatened to destroy power plants and bridges in Iran if the country fails to meet Tuesday’s deadline to reopen the Strait of Hormuz to all shipping.
He repeated previous threats to unleash “hell”, but told US media that there is a “great chance” of reaching an agreement with Tehran.
Iran mocked the ultimatum, calling it a “desperate, nervous, and foolish act”.
Trump’s latest threat came after he announced that the crew of the second US fighter jet shot down over Iran had been successfully rescued in an operation inside the highly dangerous territory.
Domestically, the government will hold a press conference on transportation and fuel oil (BBM) policies at 1:30 PM WIB. This policy is highly anticipated as it will directly affect the public.
So far, the government has not indicated any plans to raise BBM prices to safeguard the economy.
Attending today’s press conference are the Coordinating Minister for the Economy, the State Secretary, the Finance Minister, the Minister of Transportation, and the Cabinet Secretary.
In addition, market participants’ movements are also influenced by data on High Shareholding Concentration (HSC) or high stock ownership concentration in a particular issuer from the Financial Services Authority (OJK) together with the Indonesia Stock Exchange (BEI) and the Central Securities Depository (KSEI).
HSC issuers are those owned by a few parties or affiliated parties. This data started from last Thursday (2/4/2026).
This more transparent data is expected to increase confidence in the capital market among investors.
This data is taken based on the methodology for determining High Shareholding Concentration of stock ownership structure in the form of Warkat and Without Warkat as of 31 March 2026.
Based on those provisions, there are nine stocks that were announced last Thursday with ownership above 95%.
In the short term, this regulation could trigger shocks. When a large number of shares are released at once, the market is immediately flooded with supply. As a result, share prices could plummet sharply due to insufficient demand to balance it.
In normal conditions, share price movements are determined by the balance between supply and demand. However, when overhang occurs, this balance is significantly disrupted. Investors often react quickly, even tending to panic, which exacerbates selling pressure.
