Analysts from farmdoc daily and INTA forecast a third consecutive La Niña, which is rare, with only two prior triple events since 1950. The article analyzes how La Niña could affect corn yields in Brazil, the US and Argentina.
La Niña is expected to weaken but persist into early winter 2022-23.
La Niña typically brings drought risk to southern Brazil, Argentina and the US, which could cut corn and soybean output. That risk supports prices for both crops.
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.
