Grain markets saw significant movement today as geopolitical developments and weather concerns provided support for futures. Soybean futures rallied following the rejection of an Iran peace deal, though prices retraced after reaching highs of 1222'4 on the July contract. Traders remain focused on upcoming China talks and tomorrow's WASDE report. Corn futures gained strength, rising 15.25 cents from Thursday's lows. Record long positions held by money managers and frost warnings in the Northern Corn Belt pushed the December contract toward the 500'0 level, hitting a high of 498'4. Wheat futures also moved higher, tracking WTI Crude Oil futures as it tests the 100 mark. Production figures remain lower than previous year levels, contributing to the upward trend across the grain complex.
