JAKARTA – The persistent wave of foreign net selling in the Indonesian stock market is fueling a challenging cycle for the Rupiah, which has recently depreciated beyond the IDR 17,000 per US dollar mark. This situation has created a self-reinforcing downward trend, as the weakening currency, in turn, dampens investor appetite for Indonesian equities.
According to data from the Indonesia Stock Exchange (IDX), the Composite Stock Price Index (IHSG) has plummeted by 19.40% year-to-date (YtD) in 2025. Mirroring this decline, foreign investors have offloaded a net total of IDR 37.60 trillion from the market over the same period.
Muhammad Wafi, Head of Equity Research at KISI Sekuritas, explains that aggressive foreign selling is exerting significant pressure on the Rupiah, as investors convert their Rupiah-denominated assets into US dollars. “The effect on the Rupiah becomes even more pronounced when capital outflows occur simultaneously across both the stock and bond markets,” Wafi noted.
The Currency-Market Feedback Loop
Wafi warns that as the Rupiah weakens, the risks for the stock market intensify. When the currency breaches the IDR 17,000 threshold, foreign investors often adopt a more defensive stance, fearing that their returns will be eroded by unfavorable exchange rate fluctuations.
“Looking toward the second half of 2026, I expect the IHSG to remain volatile,” Wafi added. “While we may see a limited rebound should Rupiah stability improve and global interest rates decline, the market’s trajectory remains heavily dependent on foreign fund flows and macroeconomic stability.”
Sectoral Impact and Investment Strategy
The currency depreciation hits sectors with high US dollar-denominated debt particularly hard, including aviation, petrochemicals, automotive, and several consumer goods companies. In contrast, export-oriented and commodity-based sectors are viewed as more resilient, or defensive, in this environment.
For investors navigating this volatility, Wafi suggests focusing on companies with solid fundamentals and minimal currency risk, such as BBRI, BMRI, and TLKM. Additionally, commodity stocks like ADRO are recommended as potential hedges against the weakening Rupiah.
Bond Market Pressures and External Factors
The capital flight is not limited to stocks. Indonesia’s government bond market (SBN) has also faced significant pressure, with foreign holdings dropping by IDR 23.79 trillion between January and April 2026, leaving a balance of IDR 856.14 trillion.
Salvian Fernando, Head of Research and Market Information at PHEI, emphasizes that the SBN market is a primary entry point for foreign capital. “When foreign investors sell off large volumes of SBN, the resulting repatriation of funds from Rupiah to US dollars automatically spikes demand for foreign currency, putting further downward pressure on the exchange rate,” he stated.
However, analysts agree that the Rupiah’s weakness is not solely a domestic issue. Persistent global pressures, characterized by higher-for-longer interest rates, continue to dictate market sentiment. Furthermore, rising geopolitical tensions involving Iran and the US have driven investors toward safe-haven assets, further complicating the outlook for emerging markets like Indonesia.

Summary
The Indonesian stock market is currently facing significant pressure due to persistent foreign net selling, which has contributed to the Rupiah depreciating beyond IDR 17,000 per US dollar. This cycle of capital outflows has caused the Composite Stock Price Index (IHSG) to decline by 19.40% year-to-date in 2025. Market experts note that this downturn is exacerbated by global interest rate policies and geopolitical tensions, which drive investors toward safer assets and away from emerging markets.
To navigate this volatility, analysts suggest focusing on companies with strong fundamentals and minimal currency risk, such as BBRI, BMRI, and TLKM, while considering commodity-linked stocks like ADRO as a hedge. Sectors reliant on US dollar-denominated debt remain particularly vulnerable during this period of currency weakness. Investors are advised to prioritize resilience, as the market’s recovery remains heavily dependent on future stabilization of the Rupiah and global macroeconomic conditions.
