JAKARTA/BANGKOK — As “Operation Epic Fury” enters its sixth day, Southeast Asia has transitioned from a distant observer to a region on high alert. On Wednesday, March 4, 2026, the Association of Southeast Asian Nations (ASEAN) issued a rare joint statement calling for an “immediate cessation of hostilities,” warning that the U.S.-Israeli strikes on Iran—and the subsequent death of Supreme Leader Ayatollah Ali Khamenei—pose a grave threat to both global stability and the millions of Southeast Asian nationals currently in the crossfire.
While the 10-member bloc urged all parties to respect the UN Charter, the crisis has already begun to fray regional diplomatic alignments and spark an urgent scramble for energy security.
The Mediation Gamble: Prabowo’s Bold Offer
Indonesian President Prabowo Subianto emerged as the region’s most proactive diplomatic actor, offering to travel to Tehran to facilitate direct mediation. While the Iranian Embassy in Jakarta “appreciated” the gesture, the response was pointed, urging Indonesia to move beyond neutrality and formally condemn the “aggression” of the U.S.-Israeli coalition.
- Domestic Pressure: The timing of the strikes has placed Prabowo under intense domestic scrutiny. Critics have slammed his recent decision to join the U.S.-led Board of Peace for Gaza’s reconstruction as a betrayal of Indonesia’s “free and active” foreign policy.
- The Pivot: In response, Foreign Minister Sugiono signaled this week that Jakarta is now “reconsidering” its participation in the Board of Peace to preserve its standing as an impartial arbiter.
Condemnation and Concern: A Region Divided
The response across the rest of the region has been fractured by varying religious and strategic ties:
- The Critics: Malaysia and Brunei issued “strong condemnations” of the strikes. Prime Minister Anwar Ibrahim labeled the Western rhetoric on democracy as “hypocrisy,” specifically citing the reported deaths of 180 children in a strike on a school in southern Iran.
- The Pragmatists: Thailand and the Philippines have focused almost exclusively on the “humanitarian exit.” With 2.2 million Filipinos and 110,000 Thais in the Middle East, the mission is one of survival. Manila confirmed the death of a Filipina caregiver in Israel on March 1, while Bangkok has put its 58,000-strong workforce in Israel on high-tier evacuation alert.
- The Regretful: Singapore, Vietnam, and Cambodia expressed deep regret over the “failure of negotiations” and have prioritized the security of their citizens over taking sides.
The Economic Shield: Energy and Inflation
Beyond the human toll, the most immediate threat is the “energy shock.” With the Strait of Hormuz effectively paralyzed, the region’s oil-dependent economies are bracing for impact:
- Thailand’s Lockdown: The Thai government has suspended all exports of crude oil and petroleum products to safeguard domestic reserves.
- The Import Pivot: Indonesia, with two state tankers currently stuck in the Gulf, has moved to rapidly increase oil imports from the United States to fill the supply gap.
- The Vulnerability Index: Analysts at ING and Nomura warned that the Philippines is the most exposed to price surges, as it lacks the fuel subsidies common in neighboring Malaysia and Indonesia.
The Indo-Pacific “Vacuum”
Perhaps the most lasting impact for Southeast Asia is the perceived shift in U.S. attention. The Beijing-based SCSPI reported a 30% drop in U.S. reconnaissance sorties over the South China Sea in February, as assets like the USS Abraham Lincoln were diverted from the Pacific to the Gulf.
In a March 3 hearing, U.S. Senator Tammy Duckworth voiced what many in the region fear: that the war in Iran is “detracting from the focus and preparation” needed to deter aggression closer to home. For ASEAN, the 2026 Iran war is not just a Middle Eastern tragedy; it is a systemic shock that is redrawing the map of Asian security in real-time.
