DTN reports a month of very dry conditions in southern Brazil, with Parana, the second-largest soybean state, hit hardest; December rainfall through Dec. 17 was 70% to nearly 90% below normal.
Some crop loss is likely during pod filling, and some private forecasts of a 130 million ton crop are seen as unlikely.
Heat and drought during critical pod-filling in Parana point to actual yield losses, reducing Brazilian export supply and supporting soybean and meal prices.
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.
