Grain markets experienced a volatile session as technical factors and significant legal developments influenced price action. May Wheat futures led the sector higher, gaining 13.5 cents to settle at 580'2, while Corn and Soybean futures saw mixed results amid March options expiration. Market participants parsed the USDA weekly export sales report, which showed corn net sales of 1.47 million metric tons and soybean sales at 790,000 metric tons, both within expected ranges. Mid-morning volatility increased following a U.S. Supreme Court ruling regarding global tariffs, which contributed to a wide 25-cent trading range in soybean futures. Late-session commentary provided additional context for traders monitoring long-term trade policy.
