Southeast Asia is preparing for an extreme El Niño weather pattern expected to emerge before August and persist through November, threatening to exacerbate a regional cost-of-living crisis already strained by the war in Iran. According to the World Meteorological Organization, the phenomenon will likely disrupt wind patterns and increase Pacific Ocean surface temperatures, potentially stifling the monsoon rains necessary for agriculture and urban cooling.
Did You Know? Indonesia and Malaysia collectively produce approximately 85% of the global palm oil supply, a commodity that experts warn is highly sensitive to the temperature increases associated with El Niño.
How El Niño impacts regional food security
Agricultural experts warn that the region’s primary staples—rice and palm oil—are exceptionally vulnerable to climate-driven shocks. Jason Lee, chair of the Global Heat Health Information Network’s Southeast Asia Hub, stated that localized farm-level disruptions could quickly evolve into a systemic regional inflation crisis. Paul Teng of the ISEAS–Yusof Ishak Institute projects a potential 2%–8% reduction in rice output, with the most severe impacts likely in Thailand, the Philippines, Indonesia, and Cambodia.
While rice production faces immediate threats from drought and heat stress, the impact on palm oil may be delayed. Teng noted that reduced oil extraction rates and poor fruit bunch formation could manifest six to 12 months after the onset of peak temperatures. These anticipated shortages are already influencing market behavior, as traders drive up prices in anticipation of future harvest losses.
Why economic pressures are intensifying
Regional governments are facing a “fiscal breathing room” crisis as they attempt to balance high energy, food, and transport costs against the need for subsidies. The Asian Development Bank has lowered its 2026 growth forecast for developing Asia and the Pacific to 4.7%, down from 5.1%, citing the ongoing war in Iran as a primary factor. Central banks are maintaining elevated interest rates to combat food-driven inflation, even as businesses struggle with higher borrowing costs.
Expert Insight: The intersection of climate-driven agricultural failure and geopolitical fuel inflation creates a unique economic trap. While historical precedents show that rising prices for staples like rice often precede political volatility, current government budgets are already stretched by fuel subsidies and coal-based energy responses, leaving little room for additional emergency intervention.
What could happen next
Analysts warn that the combination of economic hardship and environmental stress could lead to widespread civil unrest. Recent months have already seen student-led protests in Indonesia regarding fuel prices and political tensions in the Philippines and Malaysia. Helena Varkkey of Universiti Malaya highlighted that dry conditions could also trigger transboundary haze from peatland fires, which would further complicate regional diplomacy and public health efforts.
Should the El Niño conditions manifest as predicted, governments may face increased pressure from labor strikes and mass protests. While officials still have a narrow window to secure water supplies and manage food stocks, the combination of high input costs and climate uncertainty remains a significant challenge for regional stability.
Frequently Asked Questions
When is the El Niño weather pattern expected to begin?
The World Meteorological Organization expects El Niño conditions to emerge before August and continue until at least November.
Which countries are considered most vulnerable to rice production losses?
According to Paul Teng of the ISEAS–Yusof Ishak Institute, Thailand, the Philippines, Indonesia, and Cambodia are the most vulnerable to water stress and localized drought in rice-growing areas.
How does the war in Iran affect the region’s economy?
The war has caused sharp rises in fertilizer and gas costs, which, combined with the threat of El Niño, is driving up food prices and forcing central banks to maintain high interest rates.
How might your local community adapt if food prices continue to rise due to these climate and geopolitical pressures?
