Grain Markets Hold Steady Ahead of August WASDE Report

Grain markets remained stagnant ahead of the August WASDE report, as traders positioned themselves for potential changes in supply and demand. On Tuesday, soybeans and wheat took a hit, finishing lower on the day, while corn held its ground.

Arlan Suderman, chief commodities economist at StoneX, noted that the market's lack of movement was likely due to traders' defensive positioning ahead of the report. 'Traders kind of positioning for the report, giving the appearance that they're bracing for the possibility of a bearish surprise,' he said.

Crop tours have been painting a mixed picture of crop conditions across the Corn Belt. Mike Minor's team found strong conditions in Ohio and Indiana, but spottier results in Illinois. Further west, Nebraska showed some resilience, while the Dakotas and western Minnesota struggled with worse-than-expected conditions.

Estimates for corn yield are converging around 182-184 bushels per acre, just under trend. John Heinberg of Total Farm Marketing expects Wednesday's report to land close to StoneX's 184.8 estimate, which has historically been accurate within a bushel or so.

Soybean prices remain tied to weather patterns, with large rainfall totals forecast across Iowa and northern Illinois working against any rally attempt. Demand remains strong, but the unfulfilled portion of China's $25 billion purchase framework is still a risk heading into a potential Trump-Xi meeting this fall.
