Rupiah Advances Modestly, on Track for Second Weekly Rise

The Indonesian rupiah traded near IDR 17,875 per U.S. dollar on Friday, recovering after touching IDR 17,930 in the previous session. The currency drew support from a softer U.S. dollar and easing Treasury yields following strong demand at a 30-year bond auction. Locally, August retail sales posted their fastest growth in five months, amid continued government measures to cushion households against persistent cost pressures. Meanwhile, forex reserves remained near a five-month high in September, although sustained Bank Indonesia intervention and uncertain portfolio inflows posed potential risks. Inflation risks remain in focus after September figures accelerated to a three-month high, with food prices expected to remain a key source of upward pressure through year-end. Separately, analysts expect the trade surplus to remain modest amid strong imports and subdued exports. For the week, the rupiah was on track to gain around 0.1%, marking its second straight weekly advance.

The Indonesian rupiah hovered near IDR 17,900 per U.S. dollar on Thursday, remaining in a tight range in recent sessions as the dollar index held near an 18-month high after the FOMC minutes reinforced a hawkish tone among Fed policymakers amid persistent price pressures. Middle East tensions also kept sentiment cautious, with potential disruptions to energy flows raising concerns over oil prices and Indonesia’s import costs. Meanwhile, domestic fundamentals remained in focus. Fresh data showed consumer confidence edged lower from August’s three-month high, reflecting concerns over elevated food prices and higher non-subsidised fuel costs. Headline inflation hit a three-month high in September, while August imports grew much faster than exports, though the trade surplus stayed stronger than expected. Forex reserves held relatively steady in September, near a five-month peak, but continued rupiah support by Bank Indonesia could put pressure on reserves amid uncertain portfolio inflows.

The Indonesian rupiah remained near IDR 17,900 per U.S. dollar on Wednesday, little changed from the previous session, as September forex reserves held steady around USD 146.3 billion, near a five-month high. The domestic backdrop was also supportive, with Finance Minister Suahasil Nazara projecting economic growth above 5.5% in H2 2026 after 5.45% in H1, while the government pursues more targeted spending, improved spending efficiency and tax incentives for key sectors. The World Bank likewise highlighted resilient household consumption and government spending despite global headwinds. Bank Indonesia continued to support the rupiah through spot, DNDF and offshore NDF interventions, with greater reliance on cost-effective derivatives. Traders now await consumer confidence and retail sales data, due later this week. Globally, the dollar index steadied near 102, staying elevated ahead of the Fed’s latest meeting minutes and further remarks from officials, capping room for rupiah gains.
