The main risk is a cascading shock: El Niño can suppress rainfall and raise heat across much of South and Southeast Asia, reducing water available for farms and cities, increasing fire risk, and cutting harvests just as energy and fertilizer costs make food production and imports more expensive. NOAA puts the chance of a historically strong October–December 2026 event at 75%, but stresses that associated regional impacts are more likely—not guaranteed. 1

• Drought, water and haze: Reduced rainfall and hotter conditions can deplete reservoirs and soil moisture, delay planting, lower yields, and heighten forest and peat-fire risk. Indonesian fires can produce transboundary smoke haze affecting Malaysia and Singapore, with health, transport and labor-productivity costs. 5

• Rice and palm oil: Rice is especially exposed because India, Vietnam and Thailand concentrate a large share of world exports in regions vulnerable to heat and rainfall disruption. Water stress during planting, flowering or grain filling would cut output and could lead governments to protect domestic supplies, tightening export markets further. 5 In Indonesia and Malaysia, drought and heat can reduce palm fruit yields, while fire and logistics disruptions add to supply risk.

• Food-price transmission: A shortfall in rice, edible oils and other staples raises local prices directly and raises import bills for food-deficit countries. The World Food Programme estimate is that a powerful event could add roughly 49 million people to acute food insecurity by end-2027, taking the total to 274 million across 45 countries. 3 Poor households are most exposed because food occupies a high share of their spending and they have little capacity to absorb price spikes.

• War and input-cost multiplier: Conflict-related disruptions to fuel and fertilizer raise farmers’ costs for irrigation, machinery, transport and fertilizer application. This can reduce planting or input use precisely when drought is already depressing yields; the combination is more damaging than either shock alone. 13

• Political and poverty effects: Food inflation, lost rural income, smoke-related illness and higher fiscal costs for subsidies, imports and disaster response can worsen poverty and strain public finances. Risk analysts identify India, Indonesia and the Philippines as countries where a climate-driven food shock could amplify existing food-security and civil-unrest risks, but unrest is a risk, not an inevitable outcome. 2

• Scale of global losses: “Trillions” is plausible only as a broad, multi-year global-loss comparison, not as a settled forecast for this event. One analysis cites estimated cumulative global income losses of $4.1 trillion after 1982–83 and $5.7 trillion after 1997–98 over the following five years; those figures cannot be treated as a prediction for 2026–27. 8

Two important corrections to the premise: NOAA’s current statement is that El Niño should strengthen through the end of 2026 and has over a 90% chance of being very strong in Northern Hemisphere autumn and winter; it does not guarantee a December peak or specify the stated March-2027 persistence in the cited discussion. 1 Also, I found insufficient evidence for a robust official forecast that global food commodity prices will rise by more than 15%; a cited IMF estimate for a typical El Niño is about a 5% global food-price increase within a year, while a record event could be materially worse. 8
