Soybean and corn prices saw significant declines on the Chicago Stock Exchange, with July soybean prices dropping by five dollars to $431 per ton, and even larger losses for August and September positions. This drop is due to favorable weather conditions in U.S. agricultural areas, improved crop conditions, and the rapid wheat harvest progress. Additionally, China's demand for Brazilian soybeans and the strengthening dollar against the real influenced prices. Wheat and rapeseed prices also fell in the U.S. and Europe due to favorable harvest conditions and higher-than-expected yields in Russia. Conversely, rice prices in Brazil increased due to currency adjustments.
