Today's gain in the IHSG was driven by improving geopolitical sentiment after signals from US President Donald Trump that peace negotiations with Iran would continue, alongside the IMF's July 2026 World Economic Outlook (WEO) report, which maintained its growth forecast for Indonesia at 5.0 percent for 2026 and 5.1 percent for 2027 โ still above the projected global average of just 3.0 percent, as well as the ASEAN-5 regional average of around 4.1 percent.
The rupiah also appreciated 0.35 percent to the Rp18,050โ18,065 per US dollar range at the same close.
Compared with regional peers, the IHSG's advance fell well short of the Singapore Exchange's performance.
The Straits Times Index (STI) closed up 0.7 percent, or 35.41 points, to 5,469.29 on the same day, trading in a range of 5,412.51 to 5,472.10. The STI's rally was underpinned by investor optimism over continued strong demand for chips and artificial intelligence (AI) infrastructure, in line with a broader rally in technology stocks across global markets.
A similar sentiment was reflected on Wall Street at Thursday's close US time (7/9/2026), which served as the overnight cue for Asian markets the following day.
