Rupiah Stability and Trading Strategies

Indonesia’s foreign exchange reserves saw a major increase in December 2025, reaching $156.5 billion. This gives Bank Indonesia a stronger position to defend the Rupiah against significant declines, signaling stability for the currency in early 2026. This strength suggests that we should look for strategies that benefit from lower volatility in the USD/IDR currency pair. In the second half of 2025, the central bank actively worked to prevent the Rupiah from falling below 15,800, and this increased reserve level supports that effort. Selling USD/IDR rallies may become a reliable strategy in the coming weeks. For derivative traders, the implied volatility on USD/IDR options may be too high. Selling out-of-the-money calls on the pair could be a good opportunity, as the strong reserves act as a limit on extreme price increases. This outlook is based on the assumption that Bank Indonesia will use its increased reserves to manage market fluctuations. This growth in reserves is backed by positive economic developments from 2025. Strong prices for key exports like palm oil and nickel, along with inflation cooling to 2.9% by year-end, create a favorable environment. This reduces the central bank’s need to raise interest rates to support the currency. The global situation also appears advantageous for this perspective. With the US Federal Reserve hinting at a pause in its rate-hiking cycle in late 2025, the pressure on the US dollar has subsided. This creates a more supportive environment for emerging market currencies, including the Rupiah, as we enter the new year. Create your live VT Markets account and start trading now.
