Minimum Share Price Reduced to Rp1; New ARA and ARB Rules Announced

The Indonesia Stock Exchange (IDX) has officially adjusted the minimum price limit from Rp50 to Rp1. Alongside this, the IDX has also adjusted the Auto Rejection (AR) limits for Equity Securities and Infrastructure Investment Funds (DINFRA) traded on the Regular and Cash Markets.

The primary adjustment is the change in the minimum price limit from the previous Rp50.00 to Rp1.00. This adjustment to the minimum price limit is 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 market participants with greater flexibility in managing their investment portfolios,” as quoted from an official IDX statement 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, (28/9/2026).

Regarding the Auto Rejection Upper (ARA) and Auto Rejection Lower (ARB) provisions, the asymmetric ARB of 15% for Equity Securities priced above Rp10 will remain in effect until 31 December 2026.

Furthermore, in line with the adjustment of the minimum price limit to Rp1, for securities with a price range between Rp1 and Rp10, the ARA and ARB limits are set at Rp1. Subsequently, starting from 1 January 2027, ARB provisions will return to a symmetric application based on the price range.
