Feed grains attempt a modest rebound after Friday’s heavy selloff, but the larger US corn balance, rapid South American planting and an open US harvest window keep the broader grain complex defensive.
US grain markets begin Monday, October 12, with mixed trade following Friday’s sharp reaction to the USDA production and balance-sheet updates. Corn is recovering modestly from the selloff, soybeans are lower and wheat is steady to slightly firmer, while favorable harvest conditions across much of the central Midwest continue to limit upside. Weekly export inspections and crop progress reports have been delayed until Tuesday because federal government offices are closed for the holiday.
Corn Attempts to Recover After Friday’s Supply Shock
Corn is trying to stabilize after Friday’s steep decline, but the larger US supply picture remains the dominant fundamental pressure. USDA raised US corn yield to 181.2 bpa and production to 16.034 billion bushels, while 2026/27 ending stocks increased to 1.849 billion bushels. The combination of higher production and the previously reported increase in 2025/26 carryout added 407 million bushels to total supplies.
Managed money had already been reducing exposure before the report, cutting its net long position by 60,491 contracts to 317,359 in the week ending October 6, mainly through long liquidation. The Monday outlook estimates that additional selling on Friday may have reduced that position to below 238,000 contracts, a two-month low.
Harvest Weather Remains a Limiting Factor
The US harvest window remains broadly favorable. Conditions were open across the central Midwest over the weekend, although a narrow band of heavier rain is expected to move from the southwestern Plains into the central Midwest around midweek, temporarily slowing fieldwork. The second week of the outlook remains favorable for harvest.
For soybeans, another couple of relatively open harvest days are expected before rain develops across parts of the Southern Plains, Missouri, southern Iowa, Illinois, Indiana and Ohio. That keeps seasonal supply pressure in place even as regional rainfall may briefly interrupt harvesting.
Soybeans Ease as Brazil Planting Accelerates
Soybeans are starting the week lower despite stronger soybean oil. Nov ’26 beans are down, while soybean meal is also weaker and oil is higher. Crush margins improved again to $2.66 1/2/bu.
South America is becoming increasingly important. Brazilian soybean planting has reached a record 20%, compared with 13% a year ago and a five-year average of 11.6%. Heavy rain has affected southeastern Brazil while temperatures above 100 degrees were reported across Mato Grosso, with cooler conditions across Argentina and southern Brazil. Rain continues to favor the interior south of Brazil.
Chinese purchases have slowed since late September and are estimated near 15 MMT, leaving demand as an important counterweight to the rapid Brazilian planting pace and progressing US harvest.
Wheat Holds Steady as Black Sea and Baltic Risks Persist
Wheat is comparatively stable, with Chicago, Kansas City and Minneapolis contracts holding close to Friday’s range. Black Sea and Baltic export routes remain an important source of uncertainty. Baltic countries are urging the EU to block the movement of Russian grain through the region to ports on the Baltic Sea.
APK-Inform raised its 2026 Ukrainian wheat production forecast by 0.5 MMT to 25.5 MMT, but lowered the country’s grain export forecast by 6.5% to 31.7 MMT. Russia’s IKAR also reduced its Russian wheat crop estimate to 88 MMT, down 2 MMT from its previous forecast.
Positioning remains cautious. Managed money increased its Chicago wheat net short to 29,543 contracts, while the Monday outlook notes that combined net-long positioning across the three wheat classes has fallen to only around 6,000 contracts, the smallest in three months.
US Reports Delayed Until Tuesday
Monday’s market has fewer scheduled domestic catalysts because federal government offices are closed for the holiday. Weekly export inspections and crop progress and condition reports have therefore been pushed to Tuesday. That leaves Friday’s USDA balance-sheet changes, harvest weather and positioning as the main immediate influences on trade.
Wheat Futures
Dec ’26 Chicago wheat is up $0.01 at $6.72/bu, Dec ’26 Kansas City wheat is up 1 1/4 cents at $7.20 1/2/bu, and Dec ’26 Minneapolis wheat is up $0.02 at $6.97 1/4/bu. Wheat is holding within Friday’s range, supported by uncertainty around Russian export routes and lower Russian production expectations, while larger US wheat stocks continue to limit upside.
Corn Futures
Dec ’26 corn is up $0.02 at $4.81 3/4/bu. The contract is attempting to recover from Friday’s heavy selloff, with resistance at the 100-day moving average of $4.84 3/4. The larger USDA production and stocks estimates remain the main bearish influence.
Soybean Futures
Nov ’26 soybeans are down $0.04 1/2 at $12.87 1/2/bu. Dec ’26 soybean meal is down $2.20 at $363.40, while Dec ’26 soybean oil is up 57 points at 68.59. Support for November soybeans is at the 50-day moving average of $12.68. Rapid Brazilian planting and the advancing US harvest limit gains, while stronger crush margins and soybean oil provide some underlying support.
