Indonesia’s Rupiah Hits Record Low: How the Iran War & Energy Crisis Impact Southeast Asia (2026)

The recent plunge of Indonesia's rupiah against the US dollar has sparked concern among economists and investors alike. This dramatic fall, reaching a record low of 18,028, is not just a financial statistic but a symptom of deeper economic challenges. The primary culprit? The energy crisis triggered by the US-Israel war on Iran, which has sent shockwaves through Southeast Asian economies, particularly those heavily reliant on energy imports like Indonesia and the Philippines.

The war's impact on oil prices has been particularly devastating. With oil prices soaring more than 1 percent on Wednesday alone, the pressure on trade balances in these countries has intensified. This, in turn, has led to capital outflows and a weakened currency, as evidenced by the rupiah's dramatic depreciation. The situation is further complicated by the United States' proposal of additional import duties on goods from 60 economies, including Indonesia, Malaysia, and Singapore, over alleged forced labor failures.

The Permata Bank chief economist, Josua Pardede, highlighted the psychological impact of the 18,000 rupiah threshold on market investors. This threshold, he noted, is a significant psychological barrier that can influence investor behavior. The narrowing trade surplus, caused by the surge in oil prices and the country's status as a net oil importer, has further exacerbated the situation. Indonesia's trade surplus shrank to just $89 million in April, down from $3.3 billion the previous month, reducing the dollar supply in the market.

The Bank Indonesia's efforts to stabilize the rupiah by hiking interest rates and intervening in the market have not been sufficient. The central bank raised rates by 0.5 basis points to 5.25 percent last month, the first increase in two years, but the rupiah continues to depreciate. Josua Pardede argues that the central bank's actions are not enough to reverse the depreciation, as the dollar demand for energy imports, raw materials, dividends, foreign debt payments, and seasonality needs remains high.

The situation in Indonesia underscores a broader trend in Southeast Asia. The region's economies, which are heavily dependent on energy imports, are particularly vulnerable to global energy price fluctuations. This vulnerability is further compounded by geopolitical tensions and trade policies that can disrupt supply chains and increase costs. As the region grapples with these challenges, the need for diversified energy sources and resilient economic policies becomes increasingly apparent.

In conclusion, the rupiah's dramatic fall is a stark reminder of the interconnectedness of global markets and the fragility of economies reliant on energy imports. As the world navigates the complexities of the US-Israel war on Iran and its aftermath, the Southeast Asian region must confront the need for robust economic policies that can withstand the volatility of global energy markets.
