WMO Warns of Potentially Very Strong El Niño Into 2027
Severity: WARNING
Detected: 2026-09-03T16:21:18.077Z
Summary
The World Meteorological Organization reports that El Niño conditions are now established and have a near-100% chance of persisting into early 2027, with potential to strengthen into a very strong episode. This raises multi-quarter risks of weather-driven disruptions to global agriculture, soft commodities, and some energy demand patterns.

What happened: The WMO has formally warned that El Niño is already underway, could intensify to a very strong event by late 2026, and has an almost 100% probability of persisting through February 2027. This is not a routine seasonal outlook; the emphasis on both strength and duration elevates its relevance for commodity markets.
-
Supply-side and demand impacts:
- Agriculture: Historically, strong El Niño episodes are associated with drought risk in parts of Australia, Southeast Asia, India, and southern Africa, and excess rainfall/flood risk in parts of South America and the U.S. Depending on regional manifestation, this can: • Reduce yields of palm oil, sugar, coffee, cocoa, and some grains (rice, corn, wheat) in affected regions. • Disrupt harvests and logistics through floods in South America and parts of the U.S. • Tighten global exportable surpluses and increase reliance on major exporters not hit by adverse conditions.
- Energy demand: El Niño can alter heating and cooling demand patterns (warmer winters in some northern latitudes, hotter conditions elsewhere), affecting gas and power burns. Hydro generation can also be impacted in Latin America and Asia, shifting demand to thermal coal or gas.
- Affected assets and direction:
- Grains and oilseeds: Bullish risk premium for CBOT wheat, corn, and soy, particularly for new-crop contracts as the market begins to price higher yield variance.
- Softs: Bullish for sugar (especially if India/Thailand output hit), coffee (Brazil and Central America weather risk), and cocoa (West Africa rainfall pattern shifts) as volatility and weather risk premia expand.
- Vegetable oils: Palm oil futures in Malaysia/Indonesia are particularly sensitive to El Niño-driven drought; bullish risk premium.
- Energy: Regional gas and power markets (Henry Hub, TTF, JKM) may see altered seasonal curves depending on revised heating/cooling degree day expectations and hydro output assumptions.
-
Historical precedent: Strong El Niño events (1997–98, 2015–16) were associated with notable price spikes and volatility in several softs and grains, and with significant forecast errors in agricultural output. Markets typically start building a premium months ahead as confidence in event strength and duration rises.
-
Duration of impact: This is a structural, multi-quarter driver rather than a transient shock. Pricing effects will phase in as regional weather anomalies materialize or fail to materialize, and as crop outlooks for 2026–27 planting and harvest cycles are revised. Volatility and weather-related risk premia in agricultural and some regional energy markets are likely to remain elevated into at least early 2027.
