USDA Foreign Agricultural Service projects Argentina's soybean output down 31% and corn down 20% in 2017-18 from the prior season. Since December 2017, U.S. corn prices have risen 14% and soybean prices 8%, and drought losses in Argentina are expected to exceed $3.4 billion.
A sharp cut in Argentine supply removes a major source of soybeans, meal and corn from world markets, supporting prices for feed ingredients. A large Brazilian crop should cap the rally by keeping global soy supply high.
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.
After 453 past bullish weather events, Soybean Meal moved a median +0.5% over 5 sessions (55% higher; middle half -1.6% to +2.7%), and +0.5% over 20.
