The world is bracing for the strongest El Niño on record, with meteorologists warning of record-breaking temperatures and extreme weather events. This natural phenomenon is not just an environmental concern but also a significant economic challenge, affecting everything from food production to industrial output.
Companies and investors are already feeling the heat. Publicly traded firms, especially in the food and chemicals sectors are outlining contingency plans to mitigate the impacts. Banks are warning about potential supply shocks that could drive up prices as extreme weather disrupts production chains. The economic effects are both local and cumulative, affecting individual companies and the global economy as a whole.
El Niño in a Warmer World
El Niño is not a new phenomenon, but this cycle is different. It is occurring against the backdrop of a world that has already warmed by approximately 1.5°C since the Industrial Revolution. Additionally, recent sea-surface temperatures are significantly higher than historical averages, indicating an especially strong El Niño.
A typical El Niño cycle lasts less than a year, but its economic effects can extend far longer. For example, crops destroyed by heavy rain can harm farm economies immediately and disrupt global supplies for several seasons. The European Central Bank has reported that a strong El Niño could raise global food commodity prices by as much as 9% within 16 months of onset and last for years longer. Factory flooding, on the other hand, would create immediate disaster relief challenges and take years to rebuild.
The Economic Toll
Richard Shin, CFO at the Philippines-based fast food chain company Jollibee Group highlighted the broader challenges during an earnings call. “When we think about pricing and when we think about other actions to protect our margins, we don’t look at it specific to weather patterns,” Shin said. “We look at it right across the board, what we call inflation and what we call supply chain disruptions or limitations.”
The economic hit could be enormous. A 2026 paper published in the journal Science found that the 1982-1983 El Niño drove more than $4 trillion in global income losses. In the 1997-98 cycle that total hit $5.7 trillion. With El Niño, as with climate change, the relationship between a stronger phenomenon and economic damages isn’t linear. A worse El Niño may lead to much, much worse economic outcomes.
Commodity Markets Respond
The Bloomberg Commodity Total Return Index (BCOMTR) gained around 3% this week, lifting its year-to-date return to 30%. All major sectors except industrial metals contributed to this gain. Scarcity is taking multiple forms, including geopolitical disruption, constrained energy flows, tightening agricultural supply, and increasingly volatile weather.
Agriculture has become an increasingly important part of the rally, with soft commodities leading this week’s gains while grains have also strengthened. The weather story centers increasingly on El Niño, which is expected to be unusually strong, raising the risk of disruptive weather patterns across several major agricultural producing regions. Tropical crops are particularly exposed, with coffee production in Southeast Asia, cocoa in West Africa, and sugar production across parts of Asia and Brazil all vulnerable to shifts in rainfall and temperature.
The impact is already visible in prices. Sugar has extended a powerful rebound amid concerns about production prospects in India and Thailand, while cocoa and coffee have also strengthened as traders reassess supply risks. The UN Food and Agriculture Organization’s Food Price Index rose in July to its highest level since, with cereal prices up 3.4% during the month and sugar rising 5.6%.
The concern extends beyond crop yields. Agriculture is highly energy-intensive, and the Middle East conflict has raised costs for diesel, fertilizer, transportation, and irrigation. The FAO has warned that the combination of war, expensive agricultural inputs, and El Niño could produce another bout of global food inflation later this year.
Grains face a different but equally important source of uncertainty. Escalating attacks around the Black Sea are disrupting one of the world’s most important agricultural export corridors for wheat and sunflower oil. Ukraine recently cut its 2026/27 grain export forecast by as much as 12% following Russian attacks on its seaports, while disruption has also affected Russian export infrastructure.
In addition, Chicago corn futures have risen to an 18-month high after an industry field tour across the US Midwest suggested the corn crop is smaller than previously expected, raising concerns that yield potential may be more limited than forecast. The risk is therefore increasingly two-sided: weather threatens production while geopolitical disruption threatens the ability to move available crops to consumers.
