The National Weather Service Climate Prediction Center has issued an El Niño watch, forecasting a 62% chance of El Niño forming between June and August and persisting through 2026. It puts the chance of a strong event in October to December at about one in three.
An El Niño watch signals rising risk of weather disruption to US planting and to South Asian and Australian crops later in the year. This supports a modest weather premium in corn and soybeans, though confidence in the strength of the event is low.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
After 1,072 past bullish weather events, Wheat (SRW) moved a median +0.2% over 5 sessions (55% higher; middle half -1.4% to +2.3%), and +0.3% over 20.
