Wheat started the week quietly despite further Russian strikes on Ukrainian port infrastructure, while corn remained supported by strong US export demand and growing uncertainty around yield potential. Russian 12.5% wheat for September fell to $215/t FOB Novorossiysk despite continuing logistical constraints. US corn export inspections reached 1.91 mmt, compared with 1.05 mmt a year earlier. Early Pro Farmer Crop Tour results were below last year, with Ohio corn estimated at 180.18 bpa and South Dakota at 149.09 bpa. US corn conditions also slipped another 1 pp to 60% good to excellent.
Wheat corrected as further Black Sea disruption failed to extend the recent rally, while corn eased slightly after reaching its highest level since late May. Pro Farmer results remained below last year, with Indiana corn estimated at 183.54 bpa and Nebraska at 163.61 bpa. Germany’s DBV cut its winter wheat crop estimate by 7% year on year to 20.9 mmt. EU soft wheat exports were officially reported at 1.48 mmt through August 16, compared with 2.90 mmt last year, although internal line-ups indicated actual exports closer to 3.6 mmt. Jordan also returned to the wheat market after a 70-day break, purchasing around 60k tonnes at about $318.95/t C&F.
Wheat rebounded strongly as the slowdown in Russian and Ukrainian exports became more visible, while corn reached fresh multi-month highs. Rusagrotrans estimated Russian August wheat exports at only 1.8 mmt, the lowest since 2010, while Ukraine exported just 794k tonnes of agricultural products during the first half of August. Pro Farmer’s Illinois corn estimate came in at 184.19 bpa, below 199.57 last year, while western Iowa results were also lower. A stronger euro added pressure to EU wheat competitiveness, while low Rhine water levels continued to restrict vessel loads and raise inland freight costs.




Corn extended its rally as the Crop Tour continued to challenge USDA’s yield assumptions, while wheat remained firm amid restricted Black Sea exports. Iowa corn was estimated at 193.98 bpa versus 198.43 last year, while Minnesota reached 199.01 versus 202.86. USDA reported 1.049 mmt of combined old- and new-crop corn sales, while wheat sales reached 394k tonnes. Argentina’s corn harvest advanced to 81.3% but remained 13.7 pp behind the 10-year average because of wet fields and high grain moisture. The IGC also reduced its 2026/27 global production forecasts for corn to 1,305 mmt and wheat to 817 mmt.
Corn finished the week firmly after Pro Farmer estimated the US crop at 15.344 bln bushels with a yield of 173.2 bpa, well below USDA’s 16.013 bln bushels and 180.7 bpa. Wheat eased as fewer new Black Sea headlines encouraged some profit-taking, although SovEcon lowered its Russian wheat crop estimate to 88.2 mmt. Ukraine’s grain exports through August 21 reached just 539k tonnes versus 1.73 mmt a year earlier, including 340k tonnes of wheat compared with 1.28 mmt last year. Managed money increased its net long in corn by 83.7k contracts to 250.5k, while French corn conditions held at 29% good to excellent after nine consecutive weekly declines.
