Kuya Food Express JAKARTA. The Indonesian Rupiah suffered another significant blow on Monday (May 18, 2026), plunging to a fresh record low against the US Dollar (USD).
This sharp depreciation was primarily triggered by a surge in global oil prices, fueled by the escalating conflict in the Middle East, a rise in US bond yields, and growing investor anxiety regarding Indonesia’s domestic market conditions.
Market data reveals the Rupiah plummeted by 1.19% to trade at Rp 17,668 per US Dollar. This marks the largest intraday depreciation since early September and represents its second lowest record within the past week, highlighting the currency’s acute vulnerability.

The persistent pressure on the Rupiah has positioned it as one of Asia’s worst-performing currencies year-to-date. Should this trend continue, the Rupiah is on track to record its most substantial monthly depreciation since 2016.
This volatility is deeply rooted in the escalating Middle East conflict. Recent events, including drone attacks striking United Arab Emirates (UAE) assets, Saudi Arabia intercepting aerial assaults, and Iran tightening its control over the Strait of Hormuz – a critical global oil distribution route – have sent jitters across global markets.
The geopolitical tension immediately propelled global oil prices upwards, subsequently triggering a wave of capital outflow from riskier assets in emerging markets, including Indonesia.
For a net oil-importing nation like Indonesia, this situation presents a formidable challenge. Rising energy costs intensify pressure on the current account deficit and amplify concerns over domestic inflation, creating a complex economic environment.
However, the Rupiah’s predicament is not solely attributable to external global factors. Market participants are increasingly scrutinizing domestic issues, pointing to rising concerns over the government’s fiscal discipline, questions surrounding the independence of Bank Indonesia (BI), substantial foreign capital outflow, and governance issues within the stock market following the exclusion of several Indonesian stocks from the MSCI index.
Significant pressure is also evident in the domestic stock market. The Jakarta Composite Index (IHSG) tumbled by more than 4% to 6,425.95, extending its losing streak to five consecutive days. Year-to-date, the IHSG has already corrected by over 25%, reflecting deep investor apprehension.
Rupiah at Historic Lows, Asian Currencies Under Siege
Michael Wan, an analyst at MUFG, noted that Asian currencies are currently facing multi-layered pressure stemming from the strengthening US Dollar, soaring US bond yields, and the persistent rise in energy prices.
“Oil-importing nations such as Indonesia are grappling with dual pressures, while the Rupiah is also heavily weighed down by prevailing domestic sentiment,” he elaborated.
Concurrently, the US Dollar Index has demonstrated robust strength, advancing for six consecutive sessions with an increase of over 1.5%. This broad-based USD appreciation makes it more challenging for emerging market currencies.
At the same time, yields on US 10-year government bonds have surged to their highest levels in 15 months. This tightening of global liquidity conditions places immense downward pressure on assets in developing countries.
Reflecting increased investor concerns about domestic market risks, yields on Indonesian 10-year government bonds also climbed by 5.6 basis points, reaching 6.765%.
Given this precarious situation, the upcoming meeting of Bank Indonesia’s Board of Governors this week has become a focal point for the market. For the past seven months, BI has maintained its benchmark interest rate at 4.75%.

Nevertheless, the intense pressure on the Rupiah has fueled speculation that the central bank may consider raising interest rates. Such a move would aim to safeguard exchange rate stability and restore much-needed market confidence.
To date, BI has actively intervened in the foreign exchange market through various channels, including spot transactions, domestic non-deliverable forwards (DNDF), offshore non-deliverable forwards (NDF), and secondary market purchases of government bonds, all in an effort to temper the Rupiah’s volatility.
The current wave of pressure extends beyond Indonesia, impacting other Asian currencies as well. The Indian Rupee hit a new record low of 96.185 per US Dollar, the Malaysian Ringgit weakened by 0.7%, and both the South Korean Won and Taiwan Dollar experienced corrections.
However, the Rupiah’s depreciation is considered the most profound in the region, a direct consequence of an unresolved combination of severe external factors and persistent domestic sentiment issues.
Summary
The Indonesian Rupiah recently hit a record low of Rp 17,668 against the US Dollar, driven by surging global oil prices due to Middle East conflicts and rising US bond yields. This significant depreciation, which coincides with a sharp decline in the Jakarta Composite Index, positions the Rupiah as one of Asia’s worst-performing currencies this year. As a net oil-importing nation, Indonesia faces intensified inflationary pressures and a widening current account deficit that complicates the local economic landscape.
Beyond external geopolitical factors, domestic concerns regarding fiscal discipline, central bank independence, and recent stock market governance issues have further exacerbated investor anxiety. While Bank Indonesia has intervened to stabilize the currency, market participants are now closely watching the upcoming board meeting for potential interest rate hikes. These cumulative pressures have forced regional currencies downward, yet the Rupiah remains uniquely vulnerable due to the combined impact of global market volatility and domestic sentiment.
