# U.S. grains: Corn, wheat futures climb on Black Sea tensions - Grainews

> Chicago corn and wheat futures rose about 1% on December 2 on Black Sea tensions after Ukrainian and Russian-linked attacks on vessels, and on cold weather slowing Midwest grain movement. Soybean futures fell on favorable South American weather and weaker soymeal. Analysts warned that renewed threats to Black Sea shipping could echo the 2022 price spike.

Black Sea shipping risk supports wheat and corn prices, while weaker soymeal pressures soybean-meal-based feed costs. Cold-weather logistics delays add to nearby cash tightness.
