Indonesia’s Rating Most at Risk in Southeast Asia Amid War, S&P Says

S&P Global Ratings warns Indonesia’s sovereign credit rating faces the highest risk in Southeast Asia if the Middle East conflict escalates, citing potential energy market disruptions as the primary threat. A prolonged war could destabilize global energy supplies, disproportionately impacting nations with weaker fiscal buffers, with Indonesia identified as the region’s most vulnerable economy. The report, released April 2026, highlights Southeast Asia’s exposure to energy shocks, though Indonesia’s thinner rating cushion makes it uniquely susceptible to downgrades amid sustained geopolitical tensions. S&P’s analysis suggests other regional sovereigns may also face pressure, but Indonesia’s reliance on energy imports and fiscal constraints amplify its vulnerability compared to peers like Singapore or Malaysia. The warning underscores broader concerns about emerging markets’ resilience to external shocks, with Indonesia’s rating outlook now tied to conflict duration and energy price volatility.
