The Iran war has exposed a critical vulnerability in Southeast Asia's energy infrastructure, threatening to inflate the region's import bill to $245 billion by 2035—more than triple the $80 billion spent in 2024—unless governments accelerate the transition away from oil and gas, according to an International Energy Agency report released today.
The report underscores how concentrated energy supply chains leave vulnerable economies exposed to geopolitical shocks. With Southeast Asia heavily dependent on oil and gas transported through the Strait of Hormuz, the conflict has triggered what the IEA calls a "stark wake-up call" for energy security across the region, forcing both households and governments to confront the true cost of fossil fuel dependence.
The Human Cost of Energy Vulnerability
The immediate impact has been severe. The energy shock sent Southeast Asia into what analysts describe as energy triage, leading to higher energy bills and rising inflation that directly affects working families and small businesses. In the Philippines, which declared a national energy emergency, consumers have turned to rooftop solar installations at record rates as a desperate, do-it-yourself solution to rising utility bills—a sign of how price shocks force ordinary people to shoulder the burden of systemic energy insecurity.
Ivan Cano of the Manila-based solar company EcoSolutions observed, "This is the first time I've seen a demand shock of this magnitude." The Philippines became the second-largest destination for Chinese solar exports in the first quarter of 2026, with imports around three times higher than the same period last year, reflecting the urgent grassroots response to energy costs.
Market-Driven Change and Its Limits
While consumer behavior is shifting rapidly—electric vehicle sales more than doubled in 2025 to around half a million units, with one in five cars sold regionally now electric—the report warns that market responses alone are insufficient. Fatih Birol, the IEA executive director, stated that "diversification of energy sources and supply routes is now a central priority," emphasizing the need for coordinated policy action rather than reliance on individual consumer choices.
The conflict has created a troubling paradox: while spurring renewable energy adoption, it has also reinforced dependence on coal as a short-term crisis response, likely setting back efforts to phase out fossil fuels. Nuclear power expansion is advancing in Indonesia, Vietnam, and the Philippines, but yearslong construction and regulatory processes remain, leaving these nations without immediate alternatives.
Sue-Ern Tan, head of the IEA Regional Cooperation Centre in Singapore, noted that "this energy shock is prompting not just the short-term responses, but a deeper reassessment of policy priorities and investment strategies by governments"—a recognition that structural change requires deliberate institutional action.
The Role of Regional Cooperation
To overcome its vulnerabilities, the IEA recommends that Southeast Asia reduce overall demand for imported fossil fuels through more efficient national grids and expanded investment in renewable energy sources including solar, wind, hydro, and geothermal power. Critically, the report emphasizes regional energy-sharing initiatives like the Association of Southeast Asian Nations Power Grid, suggesting that collective infrastructure development could reduce individual nations' exposure to supply shocks.
Birol stated that the wake-up call from this energy crisis may help neighboring nations overcome the political barriers that have hindered such regional projects—a tacit acknowledgment that energy security requires overcoming national rivalries through multilateral cooperation.
Laos has already signaled more aggressive policy intervention, banning the import of fuel-powered vehicles for the rest of 2026 to cut oil imports and encourage the shift to electric vehicles, demonstrating how crisis can catalyze state-led structural change.
Sam Reynolds of the U.S.-based Institute for Energy Economics and Financial Analysis stated, "The IEA report clearly highlights that Southeast Asia is at a crossroads." Despite a tentative deal to end the Iran war, fossil fuel prices will likely remain elevated, which Reynolds notes means "we will see a push towards more ambitious clean energy deployment."
The report concludes that "the Middle East conflict is both a stress test of Southeast Asia's current energy system and a catalyst to accelerate structural change"—a framing that acknowledges both the fragility of the status quo and the possibility of deliberate transformation.
Why This Matters:
Energy insecurity is not an abstract economic problem—it directly determines whether working families can afford heating, cooling, and transportation. Southeast Asia's vulnerability to supply shocks in the Strait of Hormuz reveals how globalized energy markets concentrate risk on developing economies with limited alternatives. The tripling of energy import bills by 2035 would represent a massive transfer of wealth from the region to energy exporters, constraining public investment in healthcare, education, and infrastructure. The crisis demonstrates that market mechanisms alone—rooftop solar, individual EV purchases—cannot solve structural energy vulnerability; coordinated public policy, regional cooperation, and deliberate investment in renewable infrastructure are essential. How Southeast Asian governments respond will determine whether energy security becomes more equitable and democratically controlled, or whether households continue bearing the costs of dependence on volatile global fossil fuel markets.
