Corn prices have also dropped due to good planting progress in Brazil and concerns about hot, dry weather in Argentina. Wheat prices have fallen due to fund and technical selling, but concerns about damage to the hard red winter crop from storms in the Plains are mitigated by beneficial precipitation in some areas. The extension of the Black Sea Grain Initiative is being questioned, with the current agreement set to expire soon.
