JCI and Rupiah Close Weaker Ahead of MSCI Announcement

The Jakarta Composite Index (JCI) closed down 0.78% at 6,172 in afternoon trading on Thursday, 18 June 2026. During the first session, the JCI had weakened by as much as 1.06%. According to data from the Indonesia Stock Exchange, 271 stocks advanced, 445 declined, and 243 remained unchanged. Trading volume was recorded at 23.6 billion shares with a transaction value of Rp 17.9 trillion, while the transaction frequency reached 1.77 million times. Pilarmas Investindo Sekuritas stated that the JCI’s decline occurred amid growing investor caution ahead of the Morgan Stanley Capital International (MSCI) Global Market Accessibility Review, scheduled for release in the early hours of Friday, 19 June, Indonesia time, and the Annual Market Classification Review, due on 24 June. The research team noted that both agendas are considered important for Indonesia’s status in the MSCI benchmark indices. Meanwhile, the rupiah exchange rate closed 32 points weaker at Rp 17,794 per US dollar, compared to the previous day’s close of Rp 17,764. PT Traze Andalan Futures Director Ibrahim Assuaibi said the currency’s movement was influenced by market participants’ wait-and-see attitude ahead of the MSCI decision. Ibrahim added that the exchange rate was also affected by Bank Indonesia’s policy decision to raise the benchmark interest rate by 25 basis points to 5.75%. He stated that this increase is a further step to strengthen rupiah exchange rate stabilisation and a pre-emptive measure to keep inflation in 2026 and 2027 within the government’s target range of 2.5% plus or minus 1%.
