December corn futures settled at $4.8750 per bushel on July 23, their highest close since May, as hotter and drier forecasts across the western Corn Belt and Northern Plains collided with escalating tensions in the Middle East and the Black Sea to extend the July grain rally.

Cash corn strengthened to $4.3350 per bushel, and USDA data showed new-crop export sales of 701,500 metric tons — more than double the previous week. Total U.S. corn export commitments have already surpassed the USDA's current annual export forecast, signaling robust international buying despite mixed old-crop sales.

The rally reflects a market pricing production risk rather than current supplies. Brent crude climbed above $100 per barrel after renewed attacks on global energy shipping routes, raising both fuel and freight considerations for growers. Weather forecasts point toward sustained heat across Iowa, Nebraska and the Dakotas, threatening corn pollination at its most vulnerable stage. Analysts watching the crop say continued extreme heat could push December corn toward the $5-per-bushel threshold.

Soybeans enter the critical window

November soybean futures reached $12.4375 per bushel, the strongest level for a new-crop contract since late 2023. Cash soybeans traded at $12.04, the highest since January 2024. August weather will largely determine final production, because the crop is entering pod-setting and pod-filling — the most yield-sensitive weeks of the season.

China remained the leading buyer of new-crop U.S. soybeans, purchasing more than 1 million metric tons, according to USDA data. That demand supports new-crop price expectations even as old-crop sales soften. Industry analysts estimate a two-bushel-per-acre reduction in the national average yield, if August conditions deteriorate, could push soybean futures above $13 per bushel.

Wheat splits between classes

Wheat performance diverged. Winter wheat retreated modestly after reaching three-year highs, while spring wheat continued advancing. The Wheat Quality Council crop tour pegged North Dakota spring wheat yields at 48 bushels per acre — above both last year's results and the five-year average in surveyed regions. That tour figure is a condition-based estimate from surveyed fields, not a harvested result, and persistent Northern Plains heat still clouds the remainder of the crop.

Export demand for wheat stays soft. Weekly wheat export sales of 290,000 metric tons came in below market expectations, and total U.S. wheat export commitments stand at 243.8 million bushels, down 26% year over year. That gap leaves wheat prices highly sensitive to further weather developments and shifts in international trade flows.

Margin implications

For growers, the rally cuts both ways. Higher futures and stronger cash prices lift expected farm revenues on unsold new-crop bushels, but crude above $100 per barrel raises diesel, fertilizer-linked energy costs and freight. Export logistics risk in the Black Sea adds basis uncertainty for origins competing with those flows. Traders will now watch pollination weather across Iowa, Nebraska and the Dakotas and the August pod-setting window, with USDA's condition reports and weekly export sales providing the next checkpoints on whether the market's production-risk premium holds.
