Grain futures fell on the final day of the month and quarter.

Grain futures saw broad declines on the last trading day of the quarter and month, following the release of the USDA's quarterly stocks and production estimates. The USDA reported quarterly corn stocks at 1.532 billion bushels, which was above the average analyst estimate. Wheat stocks were also higher than expected, while soybean stocks were slightly below estimates. Additionally, the latest crop progress report showed corn and soybean harvests are both 1% behind the average pace. As the U.S. harvest continues, market attention will shift toward South American weather and production.
