Following weeks of intense selling pressure, the Indonesian IDX Composite Index closed significantly higher, gaining 4.08% at the end of trade. This sharp rise extends a multi-day rally in Jakarta stocks, building on gains from previous sessions to reach a significant daily closing high. The move signals a robust return of momentum to the local exchange after a period of heightened volatility and capital outflows.
The surge was primarily fueled by improved global risk appetite following reports of a finalized peace agreement between the U.S. and Iran, which cooled oil prices and eased pressure on bond yields. Per market data, the rally was led by the financial and resource sectors; Bank Central Asia (BBCA) shares jumped approximately 17% over the past week, while resource giants Vale Indonesia and Bumi Resources saw gains of 10.3% and 12.1% respectively (per trading reports on June 15, 2026). Investor confidence was further bolstered by Bank Indonesia's surprise off-cycle rate hike to 5.5% on June 9, 2026, which helped stabilize the rupiah.
