U.S. Grain Futures Pull Back as Weather, Fund Flows and Export Data Drive Volatility

Overview

• Prices for corn, soybeans and wheat slid to weekly or multi‑week lows in the first days of August as traders took profits and month‑end long positions were liquidated.
• Speculative funds materially increased net long exposure in late July, with CFTC data showing large additions to corn and soybean positions in the week ending July 28.
• Short‑term wetter forecasts for the drier western Corn Belt, together with slipping USDA crop condition ratings, eased the July weather‑driven rallies and left yields sensitive to August weather.
• Fundamental demand remains strong: U.S. weekly export inspections showed a large corn shipment that lifted marketing‑year exports well above last year, USDA confirmed big soybean sales to China, and June corn crush/ethanol use hit record June levels.
• With funds still extended and key reports and field checks due soon — including the Aug. 12 WASDE and the Pro Farmer tour — markets are likely to see amplified price swings and renewed risk to farmer incomes and local basis levels.
