Ag markets opened the week sharply lower after the US-China trade package failed to deliver the demand boost traders had expected. China agreed to lower tariffs on US corn and wheat, but soybeans were excluded and no new purchase commitments were announced. Russian 12.5% wheat for November eased to $267/t FOB Baltic ports, while Pakistan’s latest tender drew a low offer of $339.36/t C&F, almost $9.50/t below its previous purchase. US corn inspections reached 1.57 mmt, while wheat inspections remained weak at 311k tonnes. JRC MARS also cut its EU grain maize yield forecast to 6.50 t/ha, 8% below the five-year average.
Wheat rebounded from multi-week lows as renewed Black Sea attacks and a weaker euro supported MATIF, while corn remained little changed ahead of USDA’s Quarterly Stocks report. The European Commission cut its 2026/27 EU corn crop estimate to 48.3 mmt from 50.1 mmt, while imports were held at 25.0 mmt. EU soft wheat exports reached 6.81 mmt by September 27, although internal line-ups were already around 8.5 mmt. Brussels also kept Ukraine’s tariff-free quotas unchanged at 1.3 mmt for wheat and 1.0 mmt for corn.
Corn fell sharply after USDA reported September 1 stocks at 2.095 bln bushels, well above the 1.918 bln trade estimate and 1.551 bln a year earlier. USDA also revised the 2025 corn crop 57 mln bushels lower, leaving weaker implied feed and residual demand as the main driver of the larger carry-in. US wheat production was estimated at 1.534 bln bushels, slightly above expectations, although winter wheat increased while spring wheat was cut to 450 mln bushels. Funds were heavily long corn going into the report, increasing the scale of the liquidation. Pakistan also purchased 180k tonnes of wheat at $339.36/t C&F.
Wheat recovered while corn stabilised after the USDA-driven sell-off, supported by renewed Black Sea risk and fresh import demand. Saudi Arabia returned with a 535k-tonne wheat tender for November and December shipment after cancelling the same volume in September because offers were considered too expensive. Estonia banned transit of Russian and Belarusian grain, limiting another potential alternative route around disrupted Black Sea ports. reached only 289k tonnes, while corn sales were 536k tonnes, both near the bottom of expectations. Argentina completed its 2025/26 corn harvest at a record 64 mmt.




European wheat ended the week firmer as Black Sea risk and a weaker euro supported export values, while US corn lost almost 6% over the week following the larger USDA carry-in and continued fund liquidation. Black Sea execution risk increased again after a Liberian-flagged cargo vessel was struck in an Odesa-region port. France’s corn harvest advanced to 67% complete, compared with 45% a week earlier and a five-year average of 20%. FAO’s Food Price Index rose 1.5% month on month to 136.0 in September, the highest since November 2022, with cereal prices up 5.1%. Managed money had already reduced its corn net long to 377.9k contracts before the USDA stocks report.
