The USDA's July WASDE report moved grain futures immediately on release. Private satellite imagery and crop scouts now match USDA forecasts in precision, yet traders reprice on the official numbers within hours. The report's ending-stocks method—how much grain remains after harvest and sales—still anchors basis prices, margins, and export models across the industry. That stickiness matters: algorithms can front-run human traders on XML feeds.
