Grains started the week under pressure, with corn falling to fresh multi-week lows and wheat also moving lower despite continued disruption in the Black Sea. US harvest supply and fund liquidation remained the main sources of pressure. Corn harvest reached 44%, below the 52% five-year average, while winter wheat planting advanced to 63%, also behind normal. US export inspections were weak for both corn and wheat, with corn falling to 672k tonnes and wheat to 240k tonnes. Russian 12.5% wheat from Baltic ports eased to $267/t FOB. Weather forecasts pointed to a favourable five-day window for US harvest and planting progress.
Early attempts at a recovery faded as wheat and corn closed lower again. Diplomatic headlines became slightly more constructive after talks involving Ukraine and the US, although strikes continued and no agreement had been reached. Turkey, Egypt and India proposed safe passage for vessels under their flags calling at both Ukrainian and Russian ports, with Ukraine supporting the proposal while Russia had not accepted it. EU soft wheat exports reached 8.47 mmt by October 18, while internal line-ups indicated volumes closer to 11.7 mmt. Brazil’s October corn export forecast was raised to 6.87 mmt. Despite the recent losses, wheat contracts still retained stronger year-to-date gains than corn.
Wheat fell sharply as renewed expectations for Russia-Ukraine talks triggered further liquidation, with nearby MATIF contracts losing more than 3%. Russia said it was willing in principle to resume trilateral discussions with Ukraine and the US in November, although no agreement had been reached on a ceasefire or territorial issues. Non-commercial participants reduced their MATIF wheat net long by 24.1k contracts to 153.3k. Rosario raised Argentina’s 2026/27 wheat crop estimate to 23.8 mmt from 21.0 mmt, which would make it the country’s second-largest crop on record. Lower prices also began attracting demand, with Egypt reportedly purchasing around five wheat cargoes.




Grain markets were mixed, with Chicago wheat and corn lower while MATIF recovered part of Wednesday’s decline. US corn export sales improved to 1.53 mmt, the strongest in six weeks, while wheat sales remained weak at just 240k tonnes. US wheat commitments were 33% below last year and running at their slowest mid-October pace in decades. Argentina’s corn planting reached 39.8% of the expected 8.4 mha, while wheat remained 61.7% good to excellent despite frost damage reported in some early fields. The March Chicago wheat-corn spread remained elevated but continued to narrow from its summer highs.
The week ended quietly, with wheat little changed and corn reaching another multi-month low. French soft wheat sowing accelerated to 45%, up from 15% a week earlier, while the maize harvest reached 97%. France-Algeria trade relations deteriorated further after reports that Algeria had instructed producers to halt urea exports to France. Managed money reduced its corn net long by around 85k contracts to 146k, while the Chicago SRW wheat net short increased to 51k contracts. Brent crude finished the week at $116.72/bbl, its highest close since late April, while grain prices continued to move in the opposite direction.
