Chicago soybeans slid nearly 4.5% on Friday to their lowest in over a week after rains across South America boosted crop prospects. Wheat, corn and oats also fell sharply.
Ukrainian traders saw no reason to limit corn exports for the 2020/21 season, with a final decision due January 25.
Improved South American crop prospects raise expectations of higher world supplies, pushing grain prices lower. A possible Ukrainian corn export limit remains a source of upside risk for corn.
