NOAA's June ENSO update says La Niña is favored to persist through summer, with about a 52% chance of La Niña versus 46% neutral for July–September. Its chance of returning by early winter is about 59%.
The March–May 2022 Oceanic Niño Index was -1.1°C, the second coolest on record for that period.
A continuing La Niña raises the risk of dryness and heat in the US Midwest and drought in Argentina and southern Brazil, which supports corn and soybean prices. The impact is mostly a risk premium rather than a confirmed loss.
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.
