US corn, soybean and wheat futures rose to multi-month highs on June 21 as concerns grew over dry Midwest weather and global crop shortfalls. Forecasters offered little hope of moisture for the dry areas over the next two weeks.
USDA also cut good-to-excellent corn and soybean ratings by more than expected.
Limited rain prospects and falling crop ratings raise the risk of lower US yields, which supports corn, soybean and wheat prices.
