Embrapa's meteorological bulletin reports that rainfall from January to May was well distributed across Mato Grosso, supporting development of the second-crop corn that is now being harvested. Reduced rain in June and July did not harm crops already ripening or being harvested.
Good rainfall supporting a record Mato Grosso second-crop corn harvest adds to export supply, which weighs on corn prices and keeps Brazilian corn competitive in world markets.
After 357 past bearish weather events, Corn moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.3%), and -0.5% over 20.
