U.S. Corn Hits Three-Year High on Concerns About Yields, Black Sea

US corn hit a three-year high as heat in western growing areas and excessive rain in the east lowered yield expectations. Russian attacks on grain ships in the Black Sea added pressure, and Russia refused a shipping truce.

WHY IT MATTERS

Lower USDA and Pro Farmer yield estimates tighten US supply, and Black Sea disruption cuts global corn availability. Both factors are bullish for corn prices.
