The Indonesian rupiah edged up to around IDR 17,970 per U.S. dollar on Friday afternoon after briefly sliding to IDR 18,030 previously.
The move was supported by Bank Indonesia's fresh support measures, including cheaper FX hedging facilities, efforts to expand local-currency use in trade, and adjustments to its liquidity framework to improve liquidity distribution across banks.
Earlier this week, the central bank kept its policy rate unchanged after delivering a total 100bps of hikes since May to aid the rupiah.
Even so, the currency remains on track to weaken slightly for the week, weighed by fragile sentiment as oil prices topped USD 100 a barrel, stoking fiscal concerns for Indonesia as a net oil importer.
The central bank also flagged El Niño risks that could lift food prices, though it expects inflation to stay within the target range through 2027.
Globally, the dollar index hovered near a three-week high as President Trump's latest tariffs reignited fears of a renewed trade war.
