Rupiah Eases from Three-Week High

The Indonesian rupiah edged down to around IDR 17,700 per U.S. dollar in thin holiday trading on Tuesday, reversing gains from the prior two sessions and retreating from a three-week top. Sentiment weakened as traders grew concerned about the rising cost of defending the currency after forex reserves fell in May to their lowest level in almost two years, suggesting continued central bank intervention. Domestic fundamentals were also weak, with May consumer mood falling to its lowest since September 2025 and April retail sales down for the first time in a year. External risks added pressure as Washington prepares to phase in an 18% tariff on Indonesian goods from July 24, threatening exports and capital inflows. Still, losses were capped by optimism that Bank Indonesia may remain hawkish after a total of 75bps of hikes since May, with its two-day policy meeting starting Wednesday. Globally, the U.S. dollar steadied ahead of the Fed’s first policy decision under new Chair Kevin Warsh.

Indonesia’s rupiah continued to firm on Monday, standing below IDR 17,700 per U.S. dollar and marking its highest level in three weeks, as broad dollar weakness buoyed emerging-market currencies. The dollar index slipped to its lowest in over a week after the U.S. and Iran reached a peace deal in the Middle East, easing haven demand. Locally, investors positioned ahead of Bank Indonesia’s policy meeting later this week, with speculation the board may keep its tightening bias after a total of 75 bps of hikes since May. Support also came from stabilisation efforts, including Deputy House Speaker Sufmi Dasco’s call for citizens to sell dollars, while officials stressed that centralizing export proceeds via a state-owned institution would not affect commodity pricing or contracts. However, gains were capped by fragile fundamentals: May’s drop in foreign reserves, softer consumer mood, April’s fall in retail sales, higher non-subsidized fuel costs, and persistent labor market concerns.

The Indonesian rupiah inched higher to around IDR 17,910 per U.S. dollar on Friday, snapping two sessions of weakness as the dollar index broadly weakened after President Trump signaled that a peace deal with Iran could be signed in Europe this weekend, easing geopolitical tensions and reducing haven demand. Local support efforts also drew attention, with Deputy House Speaker Sufmi Dasco Ahmad urging citizens to sell dollars to help stabilise the rupiah after repeated record lows. Focus now turns to Bank Indonesia’s policy meeting next week, where analysts expect the board to maintain its tightening stance following 75bps of hikes since May. The central bank also projected the rupiah could strengthen to IDR 16,800–17,500 next year. Gains were capped, however, by weak April data showing annual retail sales fell for the first time in a year, underscoring the drag from higher non-subsidized fuel prices. For the week, the rupiah firmed about 0.8% so far, its first advance in eleven weeks.
