The Jul-19 corn futures contract hit a three-year high before meeting resistance near $4.38 after a rally that began May 13. Record rain and Midwest river flooding pushed planting to its slowest pace on record, and money managers cut net short positions, with record fund buying on May 30.
Record-slow planting and short-covering are lifting corn prices, with acreage and yield risk supporting feed costs. Forecast drier weather could cap gains, but flooding along rivers may keep logistics and prices volatile.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
