With global oil prices climbing and fuelling concerns over Indonesia’s fiscal position, USD/IDR trades near 18,070 in Thursday’s Asian session, advancing for a second consecutive day. Pressure on the Indonesian Rupiah (IDR) has supported the pair’s upward momentum.

El Niño-related increases in food prices are also sustaining strong domestic inflationary pressure. Sentiment deteriorated further when President Prabowo criticised MSCI’s proposed revisions to Indonesia’s market classification, intensifying concerns about possible foreign capital outflows. Bank Indonesia (BI) has, however, introduced liquidity measures that have softened the Rupiah’s overall fall.
A substantial weakening in Indonesia’s external balances is now expected by Bank Indonesia, according to strategists at Brown Brothers Harriman. They note that BI “projects Indonesia’s current account deficit (1% of GDP in Q2) to widen to be between 1.6% and 2.4% of GDP in 2026.” In their view, the anticipated deterioration “raises external funding needs just as MSCI downgrade risks threaten capital outflows,” with the combination seen as “keeping IDR under downside pressure.”
Recent US Dollar (USD) weakness could nevertheless restrain further advances in USD/IDR. Signs of a slowing US economy have emerged in recent releases: housing starts declined in September, while pending home sales fell to a record low.
The outlook also hinges on expectations for US monetary policy. Traders assign an 84% probability to the Federal Reserve leaving interest rates unchanged at its next meeting, according to the CME FedWatch Tool, while pricing in a 90% likelihood of a December rate rise. Uncertainty nonetheless remains elevated after Fed Chair Kevin Warsh’s recent remarks offered no clear guidance on when, or whether, further rate changes would be needed.
At 18,070 on the daily chart, USD/IDR retains a bullish near-term outlook. Spot remains above both short- and medium-term levels, indicating that buyers are holding their ground at higher prices. With the 14-day Relative Strength Index (RSI) around 61 in positive territory, upward momentum appears robust without yet becoming overstretched.
The nine-day Exponential Moving Average (EMA), near 18,020.85, offers the first support on a decline. A more extended pullback would bring the 50-day EMA at 17,906.01 into focus as a lower dynamic support level. While the pair remains above these moving averages, the technical picture favours buying on dips. The lack of nearby overhead levels also suggests room for additional gains before new resistance areas take shape.

Global market conditions, domestic economic fundamentals, changing commodity prices and active central bank intervention all influence the Indonesian Rupiah (IDR). Its course as an emerging market currency is closely linked to the resilience of Indonesia’s economy and the pace of international economic activity.
Through monetary policy and direct market operations, Bank Indonesia (BI) has a pivotal role in stabilising the Rupiah. Changes to benchmark interest rates allow it to manage yield differentials relative to major central banks, including the US Federal Reserve, helping to attract and retain foreign portfolio investment. To moderate currency volatility, BI also employs a "triple-intervention" framework across the spot, derivative (DNDF) and government bond markets. Monetary instruments such as Sekuritas Rupiah Bank Indonesia (SRBI) complement these operations by supporting capital inflows.
Domestic inflation, trade performance and the overall state of public finances determine the IDR’s underlying strength from a macroeconomic standpoint. These fundamentals are closely connected to Indonesia’s trade and current account balances. At the global level, international investors’ appetite for or aversion to risk, together with shifts in liquidity, directly influences exchange rate movements.
Higher global commodity prices benefit Indonesia as a major exporter of palm oil, coal, nickel and natural gas. They generate trade surpluses and greater foreign currency inflows, supporting the Rupiah. The country is also a net crude oil importer, however. Higher world oil prices therefore add to its foreign exchange burden, widen the current account deficit and put downward pressure on the currency.
