JAKARTA — The Bisnis-27 Index opened in the red on Monday, May 11, 2026, as market participants adopted a cautious “wait and see” approach ahead of the highly anticipated MSCI index review for May 2026. Significant pullbacks in major stocks like BMRI, JPFA, and AKRA weighed heavily on the index’s performance.
Data from IDX Mobile at 09:05 WIB showed the index, a collaborative venture between the Indonesia Stock Exchange and Harian Bisnis Indonesia, declined by 0.97% to reach the 468.91 level. During the early session, 10 constituents recorded losses, while 16 stocks managed to post gains and one remained stagnant.
The primary downward pressure stemmed from PT Bank Mandiri (Persero) Tbk. (BMRI), which dropped 7.34% to Rp4,290. This was followed by a 5.10% decline in PT Japfa Comfeed Indonesia Tbk. (JPFA) to Rp2,420 and a 3% correction for PT AKR Corporindo Tbk. (AKRA) to Rp1,455. Furthermore, PT Bumi Resources Minerals Tbk. (BRMS) fell 2% to Rp735, while PT Merdeka Battery Materials Tbk. (MBMA) slid 1.72% to Rp570.
Despite the bearish trend, several stocks showed resilience. PT Mitra Adiperkasa Tbk. (MAPI) climbed 2.06% to Rp1,485, followed by a 1.84% increase in PT Vale Indonesia Tbk. (INCO) to Rp5,525. Additionally, market giants PT Astra International Tbk. (ASII) and PT Bank Central Asia Tbk. (BBCA) posted gains of 1.29% and 1.21%, respectively.
The Phintraco Sekuritas Research Team noted that global investors remain fixated on geopolitical developments in the Middle East, particularly the fragility of the US-Iran ceasefire. Market sentiment is further tempered by upcoming US inflation data, including CPI and PPI, as internal debates within the Federal Reserve continue regarding the future trajectory of interest rates.
On the regional front, Asian markets are monitoring monetary aggregate data along with consumer and producer inflation reports from China. Investor focus is also firmly set on the upcoming summit between US President Donald Trump and Chinese President Xi Jinping in Beijing, scheduled for May 14–15, 2026. The meeting is expected to address critical strategic issues, ranging from the US-Iran conflict and global trade to rare earth metals and regional security.
Domestically, sentiment has been dampened by the government’s proposal to increase progressive royalty tariffs on metal commodities, including nickel, copper, gold, silver, and tin. While analysts suggest the policy could boost state revenue, there are concerns that it may weigh on the basic materials sector, a traditional pillar of the Indonesia Composite Index (IHSG).
Looking ahead, market participants are monitoring domestic economic indicators such as consumer confidence, retail sales, and motorcycle sales. All eyes remain on the quarterly MSCI review, which is slated for announcement on May 12, 2026.

Summary
The Bisnis-27 Index opened lower on May 11, 2026, falling 0.97% to 468.91 as investors adopted a cautious stance ahead of the upcoming MSCI index review. The decline was largely driven by significant losses in major stocks, including PT Bank Mandiri (BMRI), PT Japfa Comfeed Indonesia (JPFA), and PT AKR Corporindo (AKRA). Despite the broader downward trend, some stocks like MAPI and BBCA managed to post gains amidst the volatile market session.
Market sentiment remains pressured by global geopolitical tensions, uncertain US inflation data, and impending discussions between the US and China.
