Chicago soybean futures experienced a decline due to combined factors of lower U.S. crushing data, favorable Brazilian crop conditions, and investor focus on the upcoming U.S. Federal Reserve interest rate decision. The most-active soybean contract on the Chicago Board of Trade was marginally lower at $9.80-3/4 a bushel. This downturn in soybeans was accompanied by steady corn futures, driven by the anticipation of tighter U.S. supply, and a slight decline in wheat futures. The strength of the dollar also played a role in making grains more expensive on the international market. In contrast, Euronext wheat futures reached a seven-week high following a significant purchase by Saudi Arabia, indicating potential issues in the supply from Russia.
