IDX Removes Minimum Share Price, JCI Drops 1%
The Jakarta Composite Index (JCI) dropped 1%, correcting 62.19 points to the level of 6,179.71 as of 10:27 WIB. This decline continues a negative trend from the opening position of 6,209.75, after having previously touched a daily high of 6,227.90 during the early trading session.
According to Stockbit, trading volume was recorded at 15.16 billion shares, slightly below the average daily volume of 17.44 billion shares. The total number of lots traded reached 151.65 million lots with a transaction value of Rp3,437.17 billion.
This decline in the JCI follows the Indonesia Stock Exchange’s (IDX) decision to amend the minimum trading price limits in the regular and cash markets. Starting Monday, 28 September 2026, the lowest share price, previously set at Rp50 per share, will be reduced to just Rp1 per share.
This policy allows shares that have been at the Rp50 level to be traded at even lower prices. The change applies through the trading mechanisms in both the regular and cash markets.
In conjunction with this, the IDX is also adjusting the Auto Rejection (AR) limits for Equity Securities and Infrastructure Investment Funds (DINFRA) traded in the regular and cash markets. The primary adjustment is the change in the minimum price limit from the original Rp50.00 to Rp1.00, accompanied by corresponding adjustments to the applicable Auto Rejection limits.
“With this change, shares previously priced at Rp50.00 can be traded within a wider price range to improve the quality of price discovery, encourage increased liquidity, and provide flexibility for market participants in managing their investment portfolios,” stated an official IDX release on Monday, (21/9/2026).
This regulatory change is governed by two IDX Board of Directors’ Decrees. Both were issued today and will come into effect on Monday, 28 September 2026.
Regarding the Auto Rejection Upper (ARA) and Auto Rejection Lower (ARB) provisions, those effective until 31 December 2026 will maintain an asymmetric ARB of 15% for Equity Securities with prices above Rp10. Meanwhile, in line with the minimum price adjustment to Rp1, for securities with a price range between Rp1 and Rp10, the ARA and ARB limits are set at Rp1. Starting 1 January 2027, ARB provisions will return to a symmetric structure based on the price range.
On the other hand, the Indonesian financial market slumped last week amidst rising global uncertainty and concerns regarding ‘higher for longer’ interest rates. The Indonesian financial market is expected to remain under pressure this week.
The Jakarta Composite Index (JCI) closed last week’s trading on Friday (25/9/2026) with poor performance. On Friday, the JCI closed down 0.90% or 56.71 points to the level of 6,241.89. The market capitalisation of the Indonesia Stock Exchange (IDX) stood at Rp10,929 trillion.
Pressure also came from foreign investors. During Friday’s trading, foreign investors recorded a net sell of Rp559.08 billion. Throughout last week, net selling was recorded at Rp3.16 trillion, which is higher than the previous week’s net sell of Rp2.96 trillion. Consequently, the accumulated foreign net sell throughout 2026 has reached Rp77.52 trillion.
In the currency market, the Rupiah was the most pressured currency in Asia last week. While the Garuda currency strengthened by 0.03% in the final trading session last week, Friday (25/9/2026), to the position of Rp17,880/US$, the Rupiah weakened by 0.85% overall during the week.
