Grain Prices Plummet Amid Improving Weather Forecasts and Energy Price Collapse

Grain markets in the US took a sharp downturn on August 4, despite weaker crop conditions and strong export demand. The decline was driven by improving weather forecasts and plummeting energy prices. Corn futures fell sharply, with December contracts settling at $4.6550 per bushel, down seven cents from the previous day.

The US Department of Agriculture (USDA) reported that 61% of the corn crop is now rated good-to-excellent, below analyst expectations. However, traders prioritized favorable weather forecasts over current field conditions, with forecasts calling for additional rainfall across key Corn Belt states and seasonally warm temperatures in the coming weeks.

Soybean futures also declined, despite another significant export announcement: private exporters reported the sale of 4.9 million bushels of soybeans to China for the 2026-27 marketing year. However, November futures fell 14.5 cents to $11.7775 per bushel.
