Foreign Investors Sell $628M in Indonesian Stocks in September
Foreign investors sold Rp 10.24 trillion in Indonesian stocks in September as the benchmark fell 6.96%. Some shares still attracted overseas buyers.
Foreign investors pulled about $628 million from Indonesian stocks in September, as the country’s benchmark index fell 6.96% amid rising global volatility. The shift reversed August’s net inflow and shows how international tensions and higher global interest rates are weighing on Southeast Asia’s largest economy.
Hasan Fawzi, an executive at Indonesia’s Financial Services Authority (OJK) who oversees capital markets, derivatives and carbon exchanges, disclosed the figures at the regulator’s monthly commissioners’ meeting on October 5, 2026. Foreign investors recorded net purchases of Rp 1.19 trillion in August before turning to net sales of Rp 10.24 trillion in September.
Foreign selling continued into October
The Jakarta Composite Index, known locally as the IHSG, closed September at 6,071.14, down 6.96% from the previous month. The decline continued into October. On Thursday, October 1, the index fell 1.01%, or 61.63 points, to 6,009.50, marking six consecutive trading sessions of losses.
Trading swung sharply that day. The index reached a high of 6,095 before dropping to 5,973, then ended at 6,009.50. Decliners outnumbered advancers: 450 stocks fell, 206 rose and 134 were unchanged.
Foreign investors recorded another net sale on October 1, though it was far smaller than September’s total. Net selling across the market came to Rp 241.86 billion, or about $14.8 million.
The outflow matters because it adds pressure to share prices and can affect companies’ access to market financing. But overseas investors did not sell every stock. Their activity varied by company, even as the broader market weakened and most shares fell.
Some stocks still drew foreign buyers
Trading data cited by Indonesian business outlet Kontan showed foreign investors made net purchases of shares in several companies at the start of October. PT Dian Swastatika Sentosa Tbk (DSSA) recorded Rp 79.13 billion in net foreign buying on October 1, equivalent to about $4.9 million.
That buying took place on a day when the benchmark fell and a majority of listed stocks ended lower. The contrast highlights how an overall foreign outflow can coexist with demand for individual shares.
OJK attributed the domestic market’s pressure in part to heightened geopolitical tensions and rising global interest rates, which have contributed to increased volatility in financial markets worldwide.
