Jakarta, June 15, 2026 — Indonesia’s benchmark stock index, the Indeks Harga Saham Gabungan (IHSG), staged a dramatic rally on Monday, soaring more than 5 percent in the first trading session.
The surge, which lifted the index to 6,309 points, marked one of the sharpest single day gains this year and underscored renewed optimism in Southeast Asia’s largest equity market.

Trading activity was exceptionally strong, with transaction values reaching Rp17.1 trillion and more than 30 billion shares changing hands.
Analysts attributed the rally to a combination of factors: a strengthening rupiah, easing oil prices, and robust demand for blue-chip stocks.
The rupiah firmed to Rp17,665 per U.S. dollar, recovering from last week’s slide toward Rp18,000. Meanwhile, Brent crude oil fell to $83.26 per barrel, alleviating inflationary pressures and boosting sentiment across manufacturing and consumer sectors.
Sector Leaders
The rally was broad-based, with major indices reflecting strong gains LQ45 rose 5.5%, IDX80 climbed 5.9%.
Chandra Asri Pacific (TPIA) surged 14.05% to Rp2,110, leading in transaction value at Rp1.56 trillion.
Bank Central Asia (BBCA) advanced 7.59% to Rp6,375, with transactions totaling Rp1.55 trillion.
Bumi Resources (BUMI) jumped 17.83% to Rp185, reflecting strong investor appetite for mining stocks.
Darma Henwa (DEWA) soared 20% to Rp396, topping the gainers list.
Amman Mineral (AMMN) rose 15.65% to Rp3,990, signaling continued strength in the resource sector.
Market breadth was overwhelmingly positive: out of nearly 960 traded stocks, 690 advanced, while only 92 declined.
Foreign investors were net buyers, further bolstering confidence in Indonesia’s equity outlook.
“The combination of a firmer rupiah and lower oil prices has created a sweet spot for equities,” said one Jakarta-based strategist.
“Investors are betting that Bank Indonesia will maintain stability in its upcoming policy meeting, which could sustain momentum in the weeks ahead.”
Despite Monday’s rally, the IHSG remains well below its 2026 peak of 9,134 points.
Analysts caution that profit-taking could follow such sharp gains, particularly as global markets remain sensitive to U.S. interest rate expectations and commodity price swings.
Still, the rebound signals that Indonesia’s market retains resilience amid volatility.
With foreign inflows returning and domestic investors showing renewed confidence, the IHSG may be poised for further recovery provided macroeconomic conditions remain supportive.
