The JCI’s trading range for the day was 6,031.28 to 6,179.09.
The decline reflected losses in 518 stocks, while 258 were unchanged and only 187 rose.
Refinitiv data cited infrastructure as the main drag, with the sector falling 5%, followed by energy, down 2.7%, and basic materials, down 2.6%.
The stocks weighing on the JCI included PT Bank Rakyat Indonesia (Persero) Tbk (BBRI), PT Amman Mineral Internasional Tbk (AMMN), PT Bank Mandiri (Persero) Tbk (BMRI), PT Barito Renewables Energy Tbk (BREN) and PT Bumi Resources Minerals Tbk (BRMS).

Market sentiment on Thursday (8 October 2026) was expected to be influenced by developments in Indonesia’s external resilience and the direction of global monetary policy. Indonesia’s foreign exchange reserves had edged down the previous day, although coverage remained above international standards; data on the country’s reserve money was also released.
Attention on Thursday turned to the minutes of the Federal Open Market Committee (FOMC) meeting, published in the early hours, and Indonesia’s consumer confidence report.
A hawkish Federal Reserve outlook, a stronger dollar index and elevated US Treasury yields could put pressure on equities and the rupiah. Minutes from the European Central Bank and US unemployment claims were also expected to inform assessments of interest-rate prospects, exchange rates and risk assets.
US Treasury yields fell on Wednesday after a nearly US$40 billion auction of 10-year notes attracted strong demand. The decline followed a period in which yields had climbed to their highest levels since 2002.
The 10-year US Treasury yield, a key benchmark for equity markets, reached 5.365% during Wednesday’s trading, its highest level since April 2002.
Yields on longer-dated bonds also rose. The 30-year Treasury yield briefly touched 5.732% before retreating following strong demand at the auction.
The US Treasury sold US$39 billion in 10-year notes at a yield of 5.300%, the highest level this century. Strong demand subsequently helped bring the yield down to about 5.27%. According to Bloomberg, bids amounted to 2.77 times the value on offer.
Indirect investors, including central banks and institutional investors, accounted for 80.34% of demand, while direct buyers made up 17.12%, underscoring strong interest in the debt.
The 30-year Treasury yield also fell to about 5.65%, in line with the strong demand for US government securities.
Rising Treasury yields are a concern for Indonesia because they can increase pressure on emerging-market assets.
Asian share markets also fell on Thursday (8 October 2026), as higher bond yields weighed on investor appetite for equities.
Japan’s Nikkei 225 fell 0.4%, South Korea’s Kospi lost 0.35%, and Australia’s S&P/ASX 200 declined 0.4%.
