Severe frosts reaching -21°C in parts of the US Plains and Midwest on January 20-22 may have killed up to 15% of unprotected winter wheat, according to the Commodity Weather Group. Wheat futures rose on the news, with Chicago SRW up 1.8% and Kansas City HRW up 1.4% on January 28, while Ukraine's winter crops face moisture shortages.
Potential US winter wheat losses tighten the supply outlook and support wheat prices, though the gain is limited by ample stocks and Black Sea export competition.
