Reuters column reports that corn crop ratings fell in southern Brazil after an unusually dry stretch. Second-crop corn was planted at the slowest pace in at least a decade, and weather now threatens yield potential.
Brazil supplies most of the world's corn exports in the mid-year window, so lower ratings tighten export availability and support corn and feed-grain prices.
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.
