Grain and oilseed markets rallied in early December on fund buying, after forecasts that 30-40% of Argentina could face dry conditions over the next three months. USDA figures show combined Argentine and Brazilian corn and soybean exports rising as a share of US exports.
Growing South American export share limits US export demand, while dryness in Argentina adds upside risk to corn and soy prices in the near term.
After 729 past bullish trade events, Corn moved a median +0.4% over 5 sessions (56% higher; middle half -1.1% to +1.8%), and +0.5% over 20.
After 696 past bullish trade events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.3% to +1.9%), and +0.7% over 20.
After 342 past bullish trade events, Soybean Meal moved a median +0.1% over 5 sessions (51% higher; middle half -1.1% to +2.6%), and +0.6% over 20.
