Rupiah Under Strains, Poised for Third Weekly Drop

The Indonesian rupiah edged lower to around IDR 17,840 per U.S. dollar on Tuesday after holding steady over the prior two sessions, weighed by broad dollar strength and cautious sentiment amid developments in the Middle East. Locally, fresh data showed Indonesia's trade surplus narrowed more than expected in April to its lowest level in six years, as imports slightly outpaced exports, eroding support from external balances. Persistent fiscal strains and capital outflows continued to pressure the currency despite Bank Indonesia's mid-May rate hikes and other stabilisation measures. Concerns also emerged over stricter forex-retention rules for exporters, even as the government argued that a new state-owned commodity trading firm could help lift fiscal revenues and bolster dollar liquidity. Meanwhile, headline inflation accelerated in May as higher energy costs from geopolitical tensions fed into domestic prices, though it remained within Bank Indonesia’s 1-1/2–3-1/2% target range.

The Indonesian rupiah hovered near IDR 17,820 per U.S. dollar on Monday in thin holiday trading, little changed from the prior session as investors awaited May inflation and April trade data due Tuesday. In April, inflation remained mild, although tensions in the Middle East continued to pose upside risks to prices. Meanwhile, March's trade surplus was driven more by weak imports than strong exports, highlighting uneven domestic demand and fragile external momentum. On the policy front, the government pledged greater transparency in a new state-owned firm set to become the sole exporter of key commodities, aiming to boost tax revenues and retain more export proceeds onshore. Officials hope the move will strengthen U.S. dollar liquidity after the rupiah touched record lows multiple times this year despite Bank Indonesia's mid-May rate hike and other stabilisation measures. Globally, the dollar index edged higher as uncertainty lingered over prospects for a lasting U.S.-Iran ceasefire.

The rupiah hovered near IDR 17,870 per U.S. dollar on Friday after briefly touching a record low of 17,970 in the prior session. Sentiment steadied as the U.S. dollar index eased on reports of a tentative U.S.–Iran peace deal, tempering fears of inflation and further Fed hikes. Still, caution lingered ahead of May inflation and April trade data due next week. Risks are building as energy costs rise, while March exports shrank and imports stayed weak, underscoring external fragility. Concerns also persist over new rules requiring exporters to retain proceeds locally, with traders doubtful the measure will meaningfully lift foreign reserves since funds remain under exporter control. The rupiah is on track for a third straight monthly drop, down nearly 3% in May and 6.6% year-to-date, ranking among Asia’s weakest alongside the Indian rupee and Philippine peso. Fiscal strains and capital outflows continue to weigh despite Bank Indonesia’s mid-May rate hikes and other stabilisation efforts.
