Indonesia May Raise Interest Rates Again to Support Rupiah and Stabilize Markets

Bank Indonesia raised its key interest rate by 25 basis points to 5.50% in a rare off-cycle decision on June 10, 2026, marking its second rate increase in weeks after a 50-basis-point hike in May. The move came as the rupiah struck an all-time low of 18,190 per US dollar on June 9, driven by sustained foreign capital outflows, falling foreign exchange reserves — down roughly US$11 billion since December 2025 to a multi-year low — and investor concern over inconsistent government policies. BI Governor Perry Warjiyo subsequently briefed European, US, and Asian investors in two separate calls to explain the rationale for the off-cycle action. The rupiah recovered to around 18,000 per dollar by Wednesday morning, and similarly strengthened against the Singapore dollar from a record low of 14,135 to approximately 13,950 per Singdollar. However, analysts from Maybank, MUFG, and Nomura cautioned that higher rates alone are unlikely to resolve the underlying pressures, which include rising oil import costs, high US interest rates attracting global capital, geopolitical tensions in the Middle East, and lingering concerns about Indonesia's fiscal position and policy direction. Some analysts project further rate hikes could push Indonesia's benchmark rate toward 6% by year-end, though this risks dampening economic growth.
