Chicago wheat prices have increased for the first time in three sessions, reaching a 17-month high, due to a drought impacting U.S. production. Soybean prices remained stable, influenced by a drought in Argentina. The U.S. Department of Agriculture reported a decrease in the condition of winter wheat in Kansas. Meanwhile, the extension of the Black Sea grain corridor agreement and a fall in Russian wheat prices may limit wheat gains. Australia has updated its wheat harvest estimate for the 2022/23 season to a record 39.2 million tonnes. However, Brazil's soybean market has seen slower crop sales compared to previous years and averages. The USDA also announced the sale of a portion of U.S. corn to Japan and unspecified other countries, though the volume was less than expected due to rumors of China's corn purchase interests.
