Breaking News! IDX Composite Opens with 1% Drop

The Indonesia Stock Exchange (IDX) Composite began trading in the red on Tuesday (29/09/2026). According to Stockbit data at 09:00 WIB, the index stood at the 6,084 level, down 69 points or 1.1% compared to the previous close.

During the opening session, the IDX Composite opened at 6,118.81. In the early movement, the index traded within a very narrow range, reaching a high of 6,125.53 and a low of 6,116.25.

In terms of trading activity, transaction volume was recorded at 11.48 million lots with a transaction value of Rp237.63 billion. This figure remains early as the market has only just opened and is subject to change as the session progresses.

Pressure on the IDX Composite occurred alongside the commencement of a new Indonesia Stock Exchange (BEI) policy, which reduced the minimum share price from Rp50 to Rp1 per share in the regular and cash markets starting Monday (28/09/2026).

The change is also accompanied by adjustments to auto-rejection limits. For shares priced between Rp1 and Rp10, the Upper Auto Rejection (ARA) and Lower Auto Rejection (ARB) limits are set at Rp1, while the 15% asymmetric ARB remains applicable for shares priced above Rp10 until the end of 2026.

The IDX stated that the change in minimum price is intended to expand the trading range of stocks, improve the quality of price discovery, boost liquidity, and provide greater flexibility for investors in managing their portfolios.

Simultaneously, external pressures continue to shadow the domestic market. Tighter global monetary policies, a strengthening US Dollar, rising energy prices, and high global interest rates still have the potential to drive volatility in emerging market financial markets, including Indonesia.

In the currency market, the Rupiah weakened again against the US Dollar at the start of the week’s trading.

Referring to Refinitiv data, the Rupiah closed depreciated by 0.53% to the position of Rp17,965/US, just35pointsawayfromthepsychologicallevelofRp18, 000/US.
