DTN's Bryce Anderson notes that Pacific Southern Oscillation Index readings and sea surface temperatures now resemble a weak El Nino, with the 30-day SOI near -10 and the 90-day near -9. Equatorial Pacific pools are 1 to 2 degrees Celsius above normal.
The article suggests a 90-day SOI at -8 or lower could affect U.S. Midwest weather.
A developing weak El Nino raises the chance of altered Midwest and South American weather in the coming season, a modest bullish factor for corn and soy risk premium.
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.
Moves of each commodity's benchmark from the last close before the event. Historical reads pool past events of the same kind; they describe what happened, not what will. Not investment advice.
