USD/IDR rose strongly in Friday’s Asian session and reached a record area of 17,185-17,190. The pair is set for strong weekly gains and remains biased higher.
The Indonesian rupiah weakened due to economic risks linked to the Middle East conflict. Indonesia is a net oil importer, so higher energy prices have raised import costs and subsidy bills.
Geopolitical Risks And Rupiah Pressure
Geopolitical tension also triggered capital outflows from Indonesia’s bond and equity markets into safe-haven assets, including the US dollar. This has supported the rise in USD/IDR over the past month.
The US Dollar Index (DXY) tried to extend its rebound from its lowest level since late February, amid uncertainty around the Strait of Hormuz. Separately, a 10-day truce between Israel and Lebanon lifted expectations of a potential US-Iran peace deal.
That backdrop supported risk appetite and, with lower expectations for a Federal Reserve rate rise, limited further US dollar strength. This may also cap USD/IDR upside in the near term.
We are seeing the USD/IDR exchange rate break through 17,180, a new all-time high that signals intense pressure on the Rupiah. For traders, this strong upward momentum suggests that buying USD/IDR call options could be a prudent move to capitalize on further expected weakness in the Rupiah. This situation feels very similar to the sharp depreciation we experienced in 2025 when the pair first crossed the 16,800 threshold.
Strategy Risks And Central Bank Watch
The primary driver is the high price of oil, which is a significant economic strain because Indonesia is a net importer. Data from last year showed our national oil and gas trade deficit exceeded $18 billion, making the Rupiah highly sensitive to sustained energy price shocks from geopolitical events. This fundamental weakness is a core reason to believe the current trend has room to run.
We are also witnessing significant capital flight from our domestic markets as global investors seek the safety of the US Dollar. The yield on Indonesia’s 10-year government bond has climbed above 7.8% this month, reflecting foreign investors selling off their holdings and converting the proceeds out of Rupiah. This outflow provides a steady stream of demand for US Dollars, pushing the exchange rate higher.
However, we must consider the factors that could limit this rally, including hopes for a de-escalation in the Middle East and the reduced likelihood of further US Federal Reserve rate hikes. This suggests that while going long on USD/IDR is the main strategy, traders might consider using bull call spreads. This would allow for profiting from a continued rise while capping potential losses if the rally suddenly stalls.
Finally, we have to anticipate potential intervention from Bank Indonesia (BI), which has historically stepped in to stabilize the currency. BI’s foreign exchange reserves have already declined by over $5 billion since the start of the year, a clear sign they are actively selling dollars to support the Rupiah. Any aggressive moves by the central bank could cause a sharp, albeit likely temporary, reversal in the USD/IDR pair.
