Deral reported 29% of Parana's safrinha corn harvested, a 13-point weekly gain, with the crop rated 52% good and 17% poor. Northern and northwestern Parana yields are below expectations after extended dryness, with some farmers harvesting for silage and filing insurance claims.
Nationwide, Brazil's safrinha harvest reached 21%, a record pace.
Below-expectation yields in key Parana areas reduce corn supply, though the fast harvest pace may add near-term export availability and pressure on spot basis.
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.
