Driven by geopolitics and weather risks, corn futures experienced weeks of rising prices, and a wave of profit settlements dragged down the US grain market, and corn recorded the biggest decline in nearly three weeks. The biggest decline in the Chicago Exchange's main corn contract reached 1.8% on Wednesday, the biggest intraday decline since August 13. Wheat and soybeans weakened at the same time. Previously, attacks on Black Sea ports and ships continued to escalate, global heatwaves threatened crop production, and the market worried about supply, driving up grain prices sharply. Corn futures fell 1.6% to $5.37 per bushel. Wheat fell 1.8% to $7.68 per bushel; soybeans fell 1.1%.
