What happened
Between January and Friday, 9 October 2026, foreign investors were net sellers of Rp 84.99 trillion on the Indonesia Stock Exchange (IDX, known locally as BEI). In the week from 5 to 9 October alone, net outflows totalled Rp 2.44 trillion.
The composite index, IHSG, edged up 0.94% over that week to close at 6,093.759, from 6,036.888 a week earlier. Year to date, however, it has fallen 29.79%.
The IHSG, or Indeks Harga Saham Gabungan, is the main benchmark for Indonesian equities and a common gauge of investor sentiment toward the country.
The week in numbers
Average daily trading value rose 28.52%, from Rp 12.63 trillion to Rp 16.23 trillion, according to the exchange. Market capitalisation grew 0.69% to Rp 10,701 trillion from Rp 10,627 trillion.
Average daily volume, by contrast, slipped 7.62% to 46.53 billion shares from 50.37 billion. Daily transactions were almost flat at 1.67 million versus 1.68 million. Acting corporate secretary Aulia Noviana Utami Putri described the week's results as mixed.
Which stocks lifted the index
Ekamas Mora Republik (MORA) contributed the most, adding 9.24 points as its shares climbed 11.88%. Astra International (ASII) added 7.71 points, Amman Mineral Internasional (AMMN) 6.48 points and Telkom Indonesia (TLKM) 6.45 points.
Merdeka Gold Resources (EMAS), Bumi Resources Minerals (BRMS) and Bank Rakyat Indonesia (BBRI) also helped, contributing 3.70, 3.34 and 2.95 points respectively.
Why the market has slumped
Hasan Fawzi, chief executive for capital market supervision at the Financial Services Authority (OJK), points to a mix of global and local pressures. Abroad, he cited geopolitical uncertainty, disrupted commodity flows, higher commodity prices feeding inflation and a slowing world economy.
Expectations that global interest rates will stay high for longer are weighing on the rupiah and on investment decisions. At home, investors are watching government policy and how it is carried out. Assessments by global index providers also shape the strategy of foreign funds.
The regulator's view
OJK still expects the market to recover. Hasan said the index's rebound from its June low shows there is room for improvement, while noting that global conditions and company earnings will keep driving prices.
The regulator says it will work with self-regulatory organisations and market players on transparency, governance, investor protection and deeper markets. The aim is to strengthen trust among domestic and foreign, retail and institutional investors.
Hasan gave his assessment at the press conference after OJK's September monthly board meeting. He did not announce new measures with dates.
Why it matters for Bali
Stocks and villas trade on different terms, but both are bets on the same country. Heavy foreign selling and a near 30% fall in the index can be read as a sign that global capital is pricing Indonesian risk cautiously right now.
The regulator itself names pressure on the rupiah as a factor. For a villa buyer who measures returns in dollars or euros, the exchange rate directly changes what rental income is worth once converted.
