From "Super El Niño" to Extreme European Heatwaves: How Climate Shocks Are Reshaping Global Commodity Supply Chains

Climate Anomalies Stacking: From 'Super El Niño' to European Heatwave

In the summer of 2026, global commodity markets are facing an unprecedented climate stress test. The World Meteorological Organization predicts that a 'strong El Niño event' will form in the tropical Pacific from July to September, while the European continent is experiencing its most persistent heatwave on record—many parts of the UK have seen temperatures exceed 30°C for nearly two consecutive weeks, France has suffered three heatwaves so far this year, even forcing the cancellation of Bastille Day celebrations. South Korea also issued its first 'severe heatwave' warnings for Gyeongsan and Pohang.

Dan Leonard of U.S. weather forecasting agency Metdesk noted that the upcoming El Niño could 'surpass' the major events of 1982, 1997, and 2015. This pattern of extreme weather is triggering a systemic reassessment of commodity markets.

Agricultural Products: Rebalancing Resilience and Vulnerability

Agriculture is the sector most sensitive to weather shocks. According to data from Société Générale, agricultural commodity prices have risen 7% this month, with soft commodities such as cocoa, coffee, and wheat gaining 8% over the past week. The USDA reported a 3.1% year-on-year increase in food prices in May, while Man Group warns that a strong El Niño could push food inflation to double digits by 2027.

Albert Chu, a natural resources portfolio manager at Man Group, analyzed that crop yields in affected regions could decline by 5% to 12%, with rice production possibly dropping by 2% to 8% under warming conditions. Corn, coffee, cocoa, and wheat are extremely sensitive to extreme heat during key growth stages (flowering, pollination, grain filling, and pod filling), and even short-term heatwaves can cause significant yield reductions.

Daryna Kovalska, a commodity strategist at Bank of America (BofA), pointed out that corn is currently significantly undervalued. Sugar production in Brazil and Thailand could plummet by 10% in the 2026-27 season due to El Niño, while corn pollination periods in Europe and the U.S. are facing hotter and drier conditions. BofA forecasts that new-season corn prices will rise from the current level of about $4.70 per bushel to $5.50-$6.00.

Energy and Metals: The Link Between Water Resources and Electricity Costs

Climate shocks do not only affect agricultural products. The natural gas market may come under pressure in winter due to higher temperatures—if the Northern Hemisphere winter is warmer than usual, lower heating demand will directly depress prices.

In metals, Chu noted that copper production is highly dependent on water resources, and drought can sharply tighten available water; aluminum is sensitive to electricity costs, which account for 30%-40% of production costs, and smelters rely on cheap hydropower. Under extreme weather, competition for electricity used in cooling, food production, and AI computing will intensify, further increasing aluminum production costs.

Supply Chain Restructuring: From Cyclical Fluctuations to Structural ChangesMan Group's Chu reminds investors, "If we regard the current El Niño as an isolated event and continue to underestimate the impact of climate on commodity volatility, that would be a real risk." The BofA team further pointed out that Europe is warming faster than any other continent, and heat stress is shifting from cyclical to structural.
