Rupiah Weakness Persists Amid Surging Oil Prices

The Indonesian rupiah slipped toward IDR 17,650 per U.S. dollar on Monday, weakening for a third session as the U.S. dollar index continued to firm ahead of the Fed’s upcoming policy meeting. The currency also faced pressure from a jump in oil prices, which could further stoke inflation and weigh on Indonesia’s fiscal position as a net oil importer. Inflation concerns deepened after headline figures accelerated to 3.19% in August, despite government efforts to contain food-price volatility amid El Niño's impact. Still, weakness was partly limited by policy assurances from Bank Indonesia Governor Destry Damayanti, who recently said policy stability would remain a key focus, with monetary, macroprudential and payment-system policies forming the main pillars of the central bank’s framework. BI is due to hold its next policy meeting next week after keeping its benchmark rate unchanged for a second consecutive month in August, following a cumulative 100bp rate hike since May.

The Indonesian rupiah weakened past IDR 17,600 per U.S. dollar on Friday, falling for a second straight session as the U.S. dollar index held gains ahead of the latest U.S. consumer price index report later today. Locally, worries over fiscal conditions persisted as global oil prices remained above USD 100 per barrel, raising pressure on Indonesia’s budget position given its status as a net oil importer. Domestic price pressures also remained a concern even as authorities stepped up measures to curb food-price volatility after annual inflation accelerated to 3.19% in August. Still, the rupiah is on track for a sixth straight weekly rise, up around 0.1% so far, supported by an improved external position as foreign exchange reserves rose to a five-month high in August. Meanwhile, new Bank Indonesia Governor Destry Damayanti said policy stability would be her focus, with monetary, macroprudential and payment-system policies forming the main pillars of the central bank’s policy framework.

The Indonesian rupiah hovered around IDR 17,530 per U.S. dollar on Thursday, after briefly strengthening below IDR 17,450 in the previous session. Concerns over oil prices above USD 100 per barrel weighed on sentiment, as Indonesia is a net oil importer, potentially straining fiscal conditions. Still, the currency remained supported by an improving outlook, with its upward momentum over the past week following Destry Damayanti’s appointment as the new Bank Indonesia governor. The external position also provided some support, with foreign exchange reserves rising to a five-month high in August, reinforcing expectations of ample buffers in the coming months. Meanwhile, domestic fundamentals strengthened, with retail sales rising for the first time in four months in July. Authorities also ramped up measures to curb food-price volatility after annual inflation accelerated to 3.19% in August. Globally, the dollar index steadied ahead of key U.S. inflation data.
