Soybeans and corn saw significant declines due to profit taking and technical selling, with soybeans further affected by mixed weather forecasts and reduced new crop export demand from China. Corn is closely watching weather conditions and potential USDA acreage adjustments, alongside stress in the Black Sea region and the nearing end of Argentina's harvest. Wheat experienced losses from fund and technical selling, with focus on the U.S. winter wheat harvest and spring wheat development in the northern U.S. Plains and Canada. Global wheat conditions in Russia, Ukraine, France, and Germany are also under scrutiny, with Taiwan seeking U.S. wheat.
