On December 30, 2022, the Surface Transportation Board directed Union Pacific to deliver corn by rail to Foster Farms in California. Insufficient deliveries had left feed stocks critically low, and the company had cut feed to dairy cattle.
UP blamed extreme winter weather for the delays, with some trains expected by January 5.
Rail delays forced a feed-short buyer to rely on costlier BNSF and truck transloads, which increases regional corn demand and delivered cost. The episode shows how weather-driven rail disruption can tighten local feed supply.
After 285 past bullish logistics events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.5% to +1.5%), and +0.8% over 20.
