Corn Posts Tuesday Losses as Crop Tour Pushes Along

Corn futures declined 3-4 cents Tuesday, with cash prices also down, as the market processed mixed agricultural data. The ProFarmer crop tour revealed higher-than-expected corn yields in Ohio and South Dakota, surpassing USDA forecasts and suggesting potential for a larger overall supply. This occurred despite a slight national deterioration in US corn crop conditions to 71% good/excellent and increased August export estimates from Brazil at 8.05 MMT, collectively contributing to the downward pressure on prices.

Analysis

Corn futures experienced downward pressure, closing 3 to 4 cents lower as the market digested new supply-side data suggesting a potentially larger-than-expected harvest. The primary catalyst is early data from the ProFarmer crop tour, which reported a strong yield in Ohio of 185.69 bushels per acre (bpa) and a particularly robust yield in South Dakota of 174.18 bpa. The South Dakota figure is highly significant as its year-over-year increase of 17.67 bpa substantially exceeds the USDA's earlier forecast of a 4 bpa gain. This bearish yield data is currently overshadowing a minor one-point decline in the weekly USDA national crop condition rating to 71% good/excellent. Adding to the supply pressure is an upward revision of Brazil's August corn export estimate to 8.05 MMT, which reinforces the narrative of ample global supply and weighs on U.S. corn prices.

Key Decisions for Investors

• The significant outperformance of the ProFarmer tour's yield findings versus prior USDA estimates, especially in South Dakota, builds a strong bearish case for near-term corn prices, warranting a review of any unhedged long positions.
• Traders should closely monitor the upcoming ProFarmer results for Nebraska and Indiana, as these will be critical in either confirming or refuting the high-yield trend, and could serve as the next major price catalyst.
• The divergence between the tour data and USDA forecasts suggests a potential for future upward revisions to official U.S. supply estimates, a key risk factor that could lead to further price declines.
• Consider that increased Brazilian exports add to global supply pressures, potentially capping any price rallies and reinforcing a sell-the-rip strategy in the near term.
