Indonesian stocks face a 29.24% year-to-date decline through 2026, driven by foreign capital outflows and global interest rates, as finance.detik.com reported. Despite regulatory assurances of structural resilience and a growing base of domestic retail investors reaching millions, the market must contend with foreign net sells totaling approximately Rp 108 trillion over the year.
Financial Services Authority Cites Global and Domestic Headwinds
Hasan Fawzi, Chief Executive of Capital Market, Derivative Finance, and Carbon Exchange Supervision at the Financial Services Authority (OJK), stated that the index drop stems from a complex mix of international and local pressures. Speaking during an online financial sector assessment press conference, Fawzi highlighted that higher-for-longer global interest rates have strengthened the U.S. dollar and triggered investment strategy adjustments by foreign funds. Domestically, market participants are closely monitoring policy dynamics, implementation hurdles, and global index provider evaluations.
The OJK noted that the IHSG closed September 2026 at 6,071.14, marking a 6,96 persen secara month to month (mtm) contraction, as reported by Kumparan.com. During September alone, foreign investors recorded a net sell of Rp 10,24 triliun in the stock market, reversing a brief net buy of Rp 1,19 triliun in August. Meanwhile, the Indonesia Composite Bond Index fell 0,23 persen secara mtm to 439.05, though state-owned securities (SBN) experienced limited foreign outflows of just Rp 0,34 triliun month to month.
Foreign Capital Outflows Versus Domestic Retail Resilience
While institutional foreign funds retreat toward high-yielding U.S. Treasury instruments, domestic participation continues to expand. OJK data shows that the total number of capital market investors grew by 1,03 juta during September alone, bringing the cumulative investor base to 32,17 juta—a 57,96 persen secara year-to-date (ytd) sepanjang 2026 surge year-to-date. Corporate funding via public offerings reached Rp 186,03 triliun through September, with another 29 planned offerings representing an indicative value of Rp 26,47 triliun in the regulatory pipeline.
Market analysts point out that Indonesian stock valuations, particularly within the banking and consumer goods sectors, have dropped to their lowest levels in 15 to 20 years. Joanne, an independent market observer cited by Kompas.id, noted that these attractive valuations coincide with strong corporate earnings, though investors remain defensively positioned ahead of the final quarter. Historically, the fourth quarter triggers seasonal window dressing, but analysts emphasize that external macro headwinds may override typical year-end rallies.
OJK imposes fines to restore investor confidence
Fawzi expressed continued optimism regarding a domestic market recovery, pointing out that the IHSG’s rebound from its annual low point in June demonstrates underlying structural room for growth. Regulators and self-regulatory organizations plan to prioritize market deepening, corporate governance, and investor protection to stabilize both retail and institutional participation.
