DTN reports that La Niña is developing more slowly than in 2020, with Pacific cooling limited to a few small areas of up to 2 degrees Celsius below average. The Oceanic Niño Index for July-September was notably less negative than in 2020.
A slower, weaker La Niña reduces the likelihood of severe South American and US drought, which is a modest bearish factor for grain and oilseed risk premiums.
