The week began with a broad sell-off across grain markets. Corn and soybeans moved sharply lower, while wheat also remained under pressure ahead of renewed attention to U.S. crop conditions, weather forecasts and developments affecting Black Sea exports.
Corn and soybeans recovered as weaker U.S. crop ratings provided support, while wheat markets were mixed. Brazil’s second corn harvest reached 58%, and wheat planting advanced to 98.8%. Ukraine had harvested 6.61 mmt of wheat and 3.49 mmt of barley. SovEcon reduced its Russian 2026/27 grain export forecast by 1.9 mmt to 44.6 mmt because of continuing navigation closures in the Sea of Azov. Russian Black Sea lineups faced tighter execution conditions after three major export terminals restricted grain deliveries by truck amid rising shipping risks. EU soft wheat exports reached 0.57 mmt by July 26, down 61% from the previous year, while barley exports were 83% lower at 0.25 mmt.
Wheat remained broadly stable and edged slightly lower, with Black Sea export concerns continuing to provide support. Corn and soybeans declined as favorable U.S. weather forecasts reduced crop concerns, while crude oil rose amid renewed Middle East tensions. Non-commercial participants increased their net long in MATIF milling wheat by 32.6k contracts to 144.5k, the highest level in more than two years. Indonesia raised its 2026 palm-oil-based biodiesel allocation to 16.75 billion litres ahead of the planned B50 mandate. Bunge said Argentina could increase soybean and sunflower oil supplies to customers affected by restrictions on Black Sea vegetable-oil availability.
MATIF wheat opened sharply higher after reports of a drone attack on a Russian grain terminal, although most of the initial gains faded. Reduced EU crop forecasts helped European wheat close modestly higher, while U.S. wheat also advanced. Corn and soybeans moved lower as favorable Midwest weather and weaker crude oil weighed on prices. The European Commission cut EU common wheat production to 124.4 mmt and reduced its export forecast to 29 mmt. Corn production was lowered to 51.9 mmt, while sunflower seed production was reduced to 9.5 mmt. Ukraine struck four Russian tankers in the Black Sea and Sea of Azov, while a separate drone attack caused significant damage to Demetra’s grain export terminal at Taman.




Grain markets ended the week under broad pressure. Wheat fell sharply in Chicago and Paris as the Black Sea rally faded and month-end positioning added selling pressure. Corn and soybeans also declined as favorable U.S. weather forecasts weighed on prices, while rapeseed followed weaker crude oil and the wider oilseed market. French soft wheat and spring barley harvesting reached 100%, while French maize conditions fell another 4 pp to 34% good to excellent. Commodity funds were net sellers across corn, soybeans, wheat, soybean meal and soybean oil during the week. China’s Sinograin sold around 249k tonnes of soybeans and announced another auction of 501k tonnes to create storage capacity for incoming U.S. cargoes.
