Corn Futures Fall to 40-Month Low

Technical signals point to momentum decisively lower. The contract is trading well beneath its 50-day moving average of 18.9 and its 200-day moving average of 18.18, while a relative strength index of 25 suggests the market remains oversold. The MACD is still negative, reinforcing the view that sellers retain control even after a brief rebound from the November lows.

The weaker price backdrop is feeding directly into agribusiness valuations. Archer-Daniels-Midland Co. has lost more than 20% since mid-September, with shares sliding to 69.97 on Nov. 6 from 88.09 on Sept. 17. Bunge Global SA has fallen to 99.1 from 119.31 over the same period. Those declines reflect not just corn’s slump but also a broader reset in trading and processing margins as the post-war supply premium unwinds.

For grain merchants, lower prices can compress merchandising spreads and reduce inventory gains. That is a shift from earlier in the year, when elevated crop prices supported results and helped sustain bullish positioning. The move also highlights how fast the market can turn once harvest progress, ample supply expectations and softer risk appetite take hold.

Farm economics face the opposite direction. Weaker corn prices cut revenue per acre just as fuel, fertilizer and financing costs remain a burden for producers. That makes government support and crop efficiency more important, while increasing the incentive for farmers to lock in prices where they can.

A narrower risk is that corn’s decline may prove too sharp if weather, export disruptions or geopolitical shocks revive concern about supplies. For now, though, the market narrative is one of easing scarcity, lower input inflation and a more difficult earnings backdrop for agricultural names tied to grain pricing.
