Indonesian Rupiah remains subdued amid market caution, external headwinds

• Indonesia’s Current account deficit hit USD 12.5B in Q2, straining Indonesia's external balance.
• Incoming BI leadership prioritizes foreign exchange flow management and proactive interest rate policies.
• Strong US inflation data and Jackson Hole speech support the Dollar, capping Rupiah gains.

USD/IDR remains stronger for the second successive day, trading around 17,760 during the Asian hours on Tuesday. The pair continues to hold its ground while the Indonesian Rupiah (IDR) faces ongoing pressure from a cautious market sentiment and persistent external headwinds.

Adding to these concerns, Indonesia’s current account deficit expanded to a record USD 12.5 billion in the second quarter of 2026. This widening gap raises red flags that high oil prices, robust domestic demand for imports, and weaker export figures will keep the nation's external balances under strain for the foreseeable future.

On the policy front, Bank Indonesia (BI) Governor candidate Destry Damayanti outlined a forward-looking economic vision aimed at balancing macroeconomic stability with accelerated domestic growth. Identifying foreign exchange flow management as a top priority, Damayanti highlighted that Indonesia’s solid internal fundamentals serve as a strong cushion against global turbulence. Moving forward, the central bank plans to fine-tune its policy mix through a pre-emptive interest rate strategy while simultaneously advancing digital payment initiatives to fuel economic expansion.

Meanwhile, the US Dollar has found renewed support ahead of the upcoming US Personal Consumption Expenditures (PCE) release, the Federal Reserve’s key inflation metric, giving the USD/IDR pair an extra upward push. Market participants are closely watching Fed Chair Kevin Warsh’s speech at the annual Jackson Hole symposium on Friday for clearer signals regarding a potential interest rate adjustment in September.

Despite this momentum, further gains for the Greenback may be limited as safe-haven demand softens. Market tension eased after reports surfaced that Iran and Oman discussed establishing a temporary joint maritime corridor in the Strait of Hormuz. With technical talks ongoing to finalize a permanent framework, the proposed corridor aims to improve strait administration, traffic management, maritime security, and real-time information sharing across the region.

Dollar risk reversals flag lingering softness in sentiment

Strategists at Scotiabank highlight that underlying Dollar sentiment remains subdued, pointing to options markets for confirmation. They note that “Dollar sentiment remains soft, as reflected in risk reversal pricing for the Bloomberg dollar index which has gravitated away from a premium for dollar calls over the past month,” underscoring a shift in positioning that leaves the currency vulnerable to renewed pressure in the absence of clearer policy signals.

Technical Analysis:

In the daily chart, USD/IDR trades at 17,761.75, extending its retreat beneath both the short-term and medium-term Exponential Moving Averages (EMAs) and keeping the near-term bias bearish. The nine-day and the 50-day EMAs sit overhead as immediate caps, suggesting rallies are likely to be sold while the pair remains below these trend markers. The 14-day Relative Strength Index (RSI) at 39 leans toward bearish momentum without yet reaching oversold territory, hinting that downside pressure could persist if price fails to reclaim the nearby EMAs.

On the topside, initial resistance is seen at the nine-day EMA at 17,817.06, followed by a more significant barrier at the 50-day EMA near 17,873.50, where a break would be needed to ease the current bearish tone and open the way for a broader recovery. With no clear moving-average supports below the market, the pair lacks a defined technical floor, leaving scope for further slippage until fresh demand emerges or momentum turns more decisively higher.
