Corn — Commitment of Traders

Corn futures trade on the CBOT in 5,000-bushel contracts and represent the largest agricultural futures market by volume. COT positioning in corn is driven by global supply and demand fundamentals — US planting intentions, South American harvests, drought conditions, and ethanol blending mandates — combined with speculative macro positioning. Hedge funds and commodity trading advisors use corn futures to express views on food inflation, energy prices (ethanol link), and emerging market demand from China. Commercial hedgers — grain elevators, ethanol producers, poultry companies, and exporters — use the market to lock in forward prices, and their net positioning is a reliable indicator of whether physical market participants believe current prices are too high or too low. The COT Index for corn flags when speculative positioning is historically extreme: record spec longs during supply scares often resolve sharply when weather fears abate. Weekly changes in the non-commercial net position track closely with USDA report surprises and are a leading indicator of corn price momentum.
