The Indonesian rupiah experienced another weakening trend, closing the trading week on Friday, May 8, 2026, at 17,382 per US dollar. This represented a depreciation of 49 points against the greenback, marking a challenging end to the week for the local currency.
The US dollar’s strength against the rupiah has been consistently evident throughout the week. According to data from Bank Indonesia’s Jakarta Interbank Spot Dollar Rate (Jisdor), the rupiah stood at 17,368 per US dollar on Monday, May 4, 2026. The currency further tested higher levels, briefly trading above 17,400 per US dollar on May 5 and 6, 2026, underscoring the persistent pressure it faces.
Looking ahead, Ibrahim Assuabi, Director of PT Traze Andalan Futures, predicts a volatile start for the Indonesian currency on Monday, May 11, 2026. He forecasts the rupiah to ultimately close weaker, trading within the range of 17,380-17,430 per US dollar, as stated in an official release quoted on Saturday, May 9, 2026. This outlook suggests continued headwinds for the rupiah.
The rupiah’s recent depreciation is largely attributed to the strengthening US dollar index. Ibrahim explained that the dollar’s appreciation against various global currencies, including the rupiah, stems from escalating tensions in the Middle East, particularly between the United States and Iran. Initially, there were hopes that the US and Iran were nearing an agreement to halt hostilities and fully reopen the Strait of Hormuz, a critical oil and gas transit route, despite persistent issues surrounding Iran’s nuclear program.
However, these hopes were quickly dashed. Renewed clashes between the US and Iran have since erupted, jeopardizing the fragile ceasefire and dimming prospects for progress in reopening the vital Strait of Hormuz, which plays a crucial role in global energy supply chains.
Domestically, the rupiah’s performance is further weighed down by concerns over government debt. As of March 31, 2026, Indonesia’s government debt surged to Rp 9,920.42 trillion. This marks a substantial increase of nearly 3 percent from Rp 9,637.9 trillion recorded at the end of December 2025. By the close of the first quarter of 2026, the government debt position represented 40.75 percent of the Gross Domestic Product (GDP), highlighting a growing burden on the national economy.
Concurrently, the state budget deficit for the first quarter reached Rp 240.1 trillion, equivalent to 0.93 percent of GDP. To cover this deficit, debt financing has already been utilized, reaching Rp 258.7 trillion, or 31.1 percent of GDP, indicating a significant reliance on borrowing to meet government expenditures.
“State revenue, particularly from taxation, is deemed crucial,” noted Ibrahim, “especially after rating agencies issued a warning to Finance Minister Purbaya Yudhi Sadewa regarding the ratio of debt interest payments to GDP.” This underscores the urgency for robust fiscal management and increased revenue generation to stabilize the nation’s financial health.

Summary
The Indonesian rupiah concluded the trading week on May 8, 2026, at 17,382 per US dollar, reflecting a persistent weakening trend driven by a strengthening US dollar. Market analyst Ibrahim Assuabi forecasts continued volatility for the coming week, predicting the currency will fluctuate between 17,380 and 17,430 against the greenback. This depreciation is largely attributed to escalating geopolitical tensions between the United States and Iran, which have disrupted global energy supply expectations.
Domestic fiscal challenges are further pressuring the currency, as Indonesia’s government debt rose to Rp 9,920.42 trillion by the end of March 2026. With the state budget deficit reaching 0.93 percent of GDP and a heavy reliance on debt financing, analysts emphasize the urgent need for improved tax revenue and fiscal management. These combined external geopolitical factors and internal debt concerns continue to create significant headwinds for the rupiah’s stability.
