Rupiah Under Strain from Narrowing Trade Surplus, Inflation Risks

The Indonesian rupiah slipped toward IDR 17,930 per U.S. dollar on Wednesday, extending prior weakness and moving closer to the 18,000 mark as a firm greenback and heightened Middle East tensions boosted demand for haven assets. Meanwhile, domestic fundamentals offered little cushion, with April's trade surplus narrowing to its lowest since 2020, reducing support from export inflows. Market caution persisted despite government measures to bolster dollar liquidity via a new state-owned commodity trading firm and tighter retention rules for exporters. Reports of local banks quoting above 18,000 underscored ongoing pressure. Meanwhile, annual inflation accelerated to 3.08% in May from 2.42% in April, driven by food and transport costs. Risks remain from global energy prices and El Niño-related disruptions. Analysts expect Bank Indonesia to keep balancing rupiah stability against growth worries after its May 50bp rate hike, with imported inflation risks still significant.

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.
