IDX-Rupiah Both Decline at Market Close Today

The Jakarta Composite Index (IHSG) and the Rupiah exchange rate both weakened at the close of trading on Monday, 8 June 2026. The IHSG closed down 4.52 per cent at the 5,342 level, while the Rupiah plummeted to Rp 18,187 per US Dollar.

According to data from the Indonesia Stock Exchange, 78 stocks gained, 701 declined, and 180 remained stagnant. Transaction volume was recorded at 29.9 billion shares with a value of Rp 21.71 trillion, while transaction frequency stood at 2.18 million times.

Equity Analyst at PT Indo Premier Sekuritas (IPOT), Hari Rachmansyah, stated that the IHSG’s movement this week was influenced by the release of foreign exchange reserve data. Bank Indonesia reported that foreign exchange reserves at the end of May 2026 decreased to US$ 144.9 billion from US$ 146.2 billion in the previous month.

“Fundamentally, the IHSG remains under significant pressure entering the week of 8–12 June 2026. The combination of May inflation exceeding expectations (3.08 per cent year-on-year), the Rupiah breaching the Rp 18,000 mark, and total net foreign selling year-to-date reaching Rp 60.8 trillion reflects a systemic erosion of investor confidence,” Hari said in a written statement on Monday, 8 June 2026.

Director of PT Traze Andalan Futures, Ibrahim Assuaibi, noted that the release of foreign exchange reserve data was also a factor affecting the Rupiah’s decline today. Additionally, he highlighted market anxiety regarding President Prabowo’s high-cost agendas.

“Market anxiety over President Prabowo’s large-scale expenditure agendas for political programmes, such as the Free Nutritious Meal (MBG) and the Red and White Village Cooperative, is causing the current account deficit to widen,” Ibrahim stated in a written statement on Monday, 8 June 2026. He added that this condition is occurring alongside a shrinking Indonesian trade surplus.
