JAKARTA — The Indeks Bisnis-27 closed in positive territory this Monday (5/25/2026), buoyed by optimistic signals regarding peace efforts in the Strait of Hormuz. Gains in major stocks, including ICBP, BBRI, and ASII, served as the primary catalysts for the index’s upward momentum.
According to IDX Mobile data, the index—developed in collaboration with Bisnis Indonesia—rose by 6.40 points or 1.46%, settling at 444.83. Throughout the trading session, the index fluctuated between a daily low of 437.06 and a high of 449.22.

The rally was spearheaded by PT Indofood CBP Sukses Makmur Tbk. (ICBP), which climbed 4.03% to Rp7,100, and PT Bank Rakyat Indonesia (Persero) Tbk. (BBRI), which gained 3.93% to reach Rp3,170.

Analysts at Phintraco Sekuritas suggest that the market’s positive sentiment was largely driven by progress in Middle East peace negotiations. Reports of potential US-Iran talks aimed at ending hostilities have triggered a correction in oil prices, effectively easing global fears regarding US inflation.
While President Trump previously announced (5/23) that a deal to reopen the Strait of Hormuz was in the works, Iranian state media has denied the claim, reporting that dozens of vessels continue to traverse the strait under Iranian surveillance. Investors are expected to keep a close watch on future developments regarding these negotiations, as they continue to impact oil prices and global market stability.
On the domestic front, market participants are preparing for the MSCI rebalancing at the end of the month, which coincides with a shortened trading week. Furthermore, caution remains prevalent among investors as they await clarity on the implementation of various new government policies.
