Soybeans hit new highs early on February 20 on soymeal strength but reversed lower after the US Supreme Court ruled IEEPA tariffs illegal. Analysts fear China could use the ruling to back away from its October 30 trade framework, including soybean purchase commitments.
Wheat made new highs and lifted corn.
Fear that China may renege on soybean purchase commitments threatens US export demand and weighs on soybean prices. Wheat strength lifts corn through feed-substitution and sentiment.
