Rupiah Closes 0.45% Weaker, US Dollar Sits at Rp18,020

The rupiah exchange rate closed weaker against the United States dollar on Thursday (4/6/2026), with the Garuda currency recording its worst level in history. According to Refinitiv data, the rupiah closed 0.45% weaker at Rp18,020/USD, confirming a breach of the new psychological level of Rp18,000/USD. Pressure on the rupiah was evident from the start of trading. The currency opened 0.11% weaker at Rp17,960/USD, but just minutes later collapsed through Rp18,000/USD and remained above that level until the close. Meanwhile, the US dollar index (DXY) was observed weakening by 0.07% to 99.463. The deepening rupiah depreciation prompted a government response. Finance Minister Purbaya Yudhi Sadewa revealed that the government had disbursed more than Rp8 trillion to stabilise the bond market. The move is intended to assist Bank Indonesia in maintaining rupiah exchange rate stability by repurchasing government securities offloaded by foreign investors. ‘Perhaps more than Rp8 trillion, in bonds,’ Purbaya said at the Parliament complex in Jakarta on Thursday. Purbaya affirmed that the government had not initially planned to disclose the progress of the bond market stabilisation policy, but noted that the measure had already had a tangible impact on the stability of the benchmark 10-year government bond yield, which is currently moving around 6.7 percent. Meanwhile, Bank Indonesia explained that the rupiah’s depreciation is still influenced by external and domestic factors. ‘The exchange rate weakness is still influenced by re-escalated Middle East geopolitical tensions which hamper peace prospects, keeping oil prices high and increasing global inflation risks as well as capital outflows from emerging countries,’ Senior Deputy Governor Destry Damayanti said in a written statement. ‘In addition, domestic demand remains quite large in line with dividend repatriation patterns and external debt payments,’ she added. BI affirmed it would increase intervention to curb rupiah depreciation and ensure proper market mechanisms, while also continuing to strengthen the interest rate structure of pro-market monetary instruments to attract capital inflows into domestic assets.
