Indonesian Rupiah faces challenges amid higher oil prices, inflationary risks
- The Indonesian Rupiah weakens due to high oil prices, El Niño-driven food inflation, and MSCI policy concerns.
- BI liquidity interventions help cushion further steep declines for the Indonesian Rupiah.
- US Dollar gains may be limited by weak US housing data and Fed rate uncertainties.
USD/IDR extends its gains for the second successive day, trading around 18,070 during Asian hours on Thursday. The currency pair has seen upward momentum as the Indonesian Rupiah (IDR) faces pressure from rising global oil prices, which have heightened fiscal concerns for the nation.
Meanwhile, elevated food costs driven by El Niño weather conditions continue to keep domestic inflationary pressures high. Market sentiment was dampened further after President Prabowo criticized MSCI’s proposed changes to Indonesia’s market classification, adding to fears of potential foreign capital outflows. Nevertheless, liquidity measures introduced by Bank Indonesia (BI) have helped cushion the Rupiah's overall decline.
IDR under pressure as BI flags wider current account gap and MSCI risks
Strategists at Brown Brothers Harriman highlight that Bank Indonesia now expects a meaningful deterioration in Indonesia’s external balances, noting 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.” They argue that this projected widening “raises external funding needs just as MSCI downgrade risks threaten capital outflows,” a combination that is seen as “keeping IDR under downside pressure.”
On the other hand, the upside for the USD/IDR pair may remain capped due to recent weakness in the US Dollar (USD). Recent economic indicators have pointed to a slowing US economy, highlighted by a downturn in September housing starts and pending home sales dropping to a record low.
Additionally, expectations surrounding US monetary policy are shaping the outlook. According to the CME FedWatch Tool, traders are currently pricing in an 84% chance that the Federal Reserve will hold interest rates steady at its upcoming meeting, alongside a 90% probability of a rate hike in December. However, market uncertainty remains high following recent comments from Fed Chair Kevin Warsh, who declined to provide clear guidance on the timing or necessity of future rate adjustments.
Technical Analysis:
In the daily chart, USD/IDR trades at 18,070. The pair holds a near-term bullish bias as spot remains above both the short- and medium-term, suggesting buyers are defending higher ground. The 14-day Relative Strength Index (RSI) at roughly 61 leans into positive territory, hinting that upside momentum is firm but not yet overstretched.
On the downside, immediate support is seen at the nine-day Exponential Moving Average (EMA) near 18,020.85, with the 50-day EMA at 17,906.01 providing a deeper dynamic floor if a pullback extends. As long as USD/IDR holds above these moving averages, the technical backdrop favors dips being bought, with the absence of nearby overhead levels implying scope for further gains before fresh resistance zones are established.

Indonesian Rupiah FAQs
The Indonesian Rupiah (IDR) is sensitive to a dynamic mix of global market conditions, domestic economic fundamentals, commodity price shifts, and proactive central bank interventions. As an emerging market currency, the Rupiah’s trajectory depends heavily on both domestic resilience and international economic momentum.
Bank Indonesia (BI) plays a central role in stabilizing the Rupiah through strategic monetary policy and direct market operations. By adjusting benchmark interest rates, the central bank manages yield differentials against major global central banks like the US Federal Reserve to attract and retain foreign portfolio investments. BI also utilizes a "triple-intervention" framework—operating across spot, derivative (DNDF), and government bond markets- to smooth out currency volatility, complemented by monetary instruments like Sekuritas Rupiah Bank Indonesia (SRBI) to bolster capital inflows.
From a broader macroeconomic perspective, domestic inflation rates, trade performance, and overall fiscal health dictate the IDR's underlying strength. Indonesia's trade and current account balances are closely tied to these fundamentals, while broader global factors, such as risk-on or risk-off sentiment among international investors and global liquidity trends, directly affect exchange rate movements.
As a major exporter of commodities such as palm oil, coal, nickel, and natural gas, Indonesia benefits from higher global commodity prices, which generate trade surpluses, increase foreign currency inflows, and strengthen the Rupiah. However, because Indonesia is also a net importer of crude oil, elevated global oil prices increase the foreign exchange burden, widening the current account deficit and weighing on the currency's value.
