World prices for oil and agricultural products, including oil and agricultural futures in Chicago, Kansas City, Minneapolis, Paris Euronext, wheat, and corn, have experienced a decline due to several factors. These include concerns about the Chinese economy, Argentina's decision to reduce export duties on various goods, and the US starting tariff wars. Argentina is facing potential harvest forecast cuts due to weather conditions, while China's manufacturing and non-manufacturing PMI indicators have shown contraction, impacting demand for US soybeans. Brazil has emerged as China's top soybean supplier, replacing the US, which has seen a drop in its import share.
