StoneX expects reduced Argentine soybean and corn crops in 2020-21, citing planting delays and dry weather linked to La Niña. The Buenos Aires exchange puts corn at 47 million tonnes and soybeans at 45.5 million tonnes.
Smaller South American crops shift attention to Brazil and tighten export supply, supporting soybean and corn prices while weather remains the key risk.
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 1,465 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.
