UN Warns of Potentially Strongest El Niño in 40 Years
Severity: WARNING
Detected: 2026-10-21T19:05:22.549Z
Summary
The WMO warns that the developing El Niño could be the strongest in four decades, with Pacific sea surface temperature anomalies potentially reaching +3.8°C in late 2026. This would materially increase the risk of multi-region crop stress, flooding, and storms, adding a medium-term bullish bias to several agricultural and soft commodity complexes.
Details
-
What happened: The World Meteorological Organization (WMO) stated that the current El Niño event could become the strongest in 40 years, with tropical Pacific sea surface temperatures forecast to rise up to 3.8°C above average between November 2026 and January 2027. The statement references likely above-average rainfall in East Africa and heightened risks of drought or excessive heat in other key regions (details not fully quoted but consistent with past strong El Niño patterns).
-
Supply/demand impact: A very strong El Niño historically correlates with significant disruptions to global agricultural output. Typical patterns include: (a) crop stress and yield losses in parts of Southeast Asia, Australia, and sometimes India (palm oil, rice, wheat, sugar); (b) variable impacts in South America, including potential problems for soy, corn, and sugar in Brazil/Argentina depending on regional rainfall anomalies; and (c) fisheries disruption off Peru/Chile, affecting fishmeal and related feed markets. On the demand side, extreme heat or cold spells in various regions can alter power and heating fuel usage, but the primary impact is on agricultural supply.
-
Affected assets and direction: El Niño risk is generally bullish for grains (corn, wheat), oilseeds (soybeans), palm oil, and sugar, as well as some livestock complexes via feed costs. Fertilizer demand volatility could rise as farmers try to offset yield risk. Power demand shifts may marginally support natural gas in some markets, but the main tradable effect is in agri and softs. Weather-linked agricultural ETFs and regional food CPI expectations may also reprice.
-
Historical precedent: The 1997–98 and 2015–16 strong El Niño events were associated with notable price spikes or persistent strength in several ag complexes, especially when coinciding with local policy restrictions (export bans) or low starting inventories. Markets typically begin to price risk before full physical confirmation once credible meteorological agencies flag a major event.
-
Duration of impact: The risk window spans at least one to two crop cycles (6–18 months), depending on hemispheric growing seasons. The strongest pricing impact will come if subsequent on-the-ground reports confirm planting delays, yield downgrades, or government export controls. Initial moves on this WMO guidance alone can reach the >1% magnitude in weather-sensitive contracts as positionholders rebalance.
