The USDA's report on the global decrease in production and stocks of major agricultural crops has led to a significant increase in prices in the reference exchanges. Corn prices have seen the largest increase, rising by up to 11 euros in Paris and 9 euros in Chicago. Soybeans and rapeseed have also experienced a sharp rise in price, while wheat prices have seen the least increase. Oats, on the other hand, saw the largest drop in price on the Chicago market. The reduction in stocks and global production, as reported by the USDA, has contributed to the market's reaction.
