Rupiah Faces Continued Pressure Amid Dollar Strength

Economic Factors Driving Depreciation

The Indonesian rupiah has been under significant pressure, depreciating to approximately Rp16,850 per USD as of January 12, 2026. This marks its seventh consecutive day of decline, continuing the weakness observed since late April 2025 ¹

. The primary factors contributing to this depreciation include the strengthening dollar index and domestic economic concerns.

Dollar Index Strength and Global Factors

The dollar index has shown a notable uptrend, rising to around 98.790 as of January 12, 2026, representing a 0.48% weekly gain and 0.44% monthly gain ²

. Analysts attribute this strength to solid US economic data releases and unexpected political developments. The robust dollar has been a significant headwind for emerging market currencies, including the rupiah.

Domestic Economic Concerns

Domestically, Indonesia faces challenges that are exacerbating the rupiah's weakness. Consumer sentiment dropped in December 2025 after reaching a nine-month high in the previous month, adding to investor caution ¹

. Despite this, Indonesia's external position remains robust, with foreign reserves reaching a nine-month high in December 2025, providing some support to the currency ¹.

Monetary Policy and Interest Rates

Bank Indonesia's monetary policy stance has been another critical factor. The central bank has implemented cumulative rate cuts of 150 basis points between September 2024 and September 2025, aiming to support economic growth while keeping inflation within target ¹

. However, this easing cycle has put additional pressure on the rupiah, as investors speculate on potential further rate reductions.

Outlook and Forecasts

Analysts predict that the rupiah will continue to face pressure in the first quarter of 2026. The dollar index is expected to remain strong, potentially maintaining the current trend ³

. Chief Indonesia and India Economist at HSBC Global Research, Pranjul Bhandari, noted that the rupiah's depreciation is more influenced by weak capital inflows rather than trade performance ⁷.
