The Jakarta Composite Index (JCI) experienced a significant downturn, plunging by up to 5 percent during the first trading session today, Wednesday, June 3, 2026. By 11:53 AM WIB, the JCI had collapsed by 5.01 percent, settling at the 5,885.1 level. This sharp decline followed an optimistic start to the day, with the index opening in the green zone at 6,207.1.
David Kurniawan, an Equity Analyst at PT Indo Premier Sekuritas (IPOT), emphasized that the future direction of the market will be heavily influenced by the stability of the exchange rate. In a press release issued on Tuesday, June 2, 2026, Kurniawan stated, “If the rupiah can demonstrate stabilization in the coming weeks, market sentiment has the potential to improve, paving the way for the return of foreign funds to both domestic stock and bond markets.”
Kurniawan further elaborated that despite Bank Indonesia’s decision to raise interest rates to 5.25 percent to curb external pressure, the market remains cautious. Investors are closely monitoring whether this policy will prove effective enough to withstand rupiah volatility and mitigate ongoing capital outflow pressures. Beyond domestic concerns, the analyst highlighted that the trajectory of United States monetary policy will also be a primary focus for markets throughout this week.
Concurrently, at 11:25 AM WIB, the rupiah exchange rate continued its weakening trend, reaching Rp 17,930 per US dollar. Ibrahim Assuaibi, Director of PT Traze Andalan Futures, attributed the rupiah’s external depreciation primarily to the stalled negotiations between the US and Iran. This geopolitical stalemate, he noted, has contributed to a resurgence in global crude oil prices.
Domestically, Ibrahim pointed to a high demand for dollars as another significant factor contributing to the rupiah’s weakness. He explained in a statement on Wednesday, June 3, 2026, “On the other hand, the public is now continuously shifting their funds from conventional savings accounts to foreign currency savings.” This trend further exacerbates the pressure on the national currency.
In light of these economic challenges, Ibrahim stressed the critical need for the government to maintain economic stability and protect the purchasing power of the community. He suggested that the government should ensure the consistent availability of imported goods and implement stimulus measures to support the public effectively.
