May corn futures fell toward key support near 450 as tariff fears grew. The U.S. imposed 25% tariffs on Canada and Mexico and an extra 10% on Chinese goods, and China responded with a 15% tariff on U.S. agricultural goods including corn and a 10% tariff on soybeans.
China also halted purchases from three U.S. soybean exporters.
Retaliatory tariffs make U.S. grain more expensive for key buyers, which can cut export demand and pressure futures. Lower U.S. prices may help other exporters win business.
