Grain markets open the first full week of October higher, with wheat supported by renewed Black Sea disruption and soybeans rebounding as the trade shifts attention toward US harvest progress and Friday’s USDA production update.
US grain markets are broadly higher on Monday, October 5. Wheat and soybeans are leading the rebound, while corn is posting more modest gains. Improving harvest weather across much of the US limits upside for row crops, but Black Sea supply risk, soybean crop-quality concerns and positioning ahead of Friday’s USDA update are providing support.
Black Sea Risk Pushes Wheat Higher
Wheat is the strongest part of the grain complex Monday morning. Russian strikes damaged port infrastructure in Odesa and destroyed a vessel loaded with grain, renewing concerns around Black Sea logistics. Ukraine’s wheat exports since July 1 stand at 2.9 MMT, down 43% year over year, while only 30% of the country’s winter crop has been planted.
Fresh international demand is also supportive. Saudi Arabia purchased 683,000 MT of wheat, exceeding the original 535,000 MT tender, with supply sourced from several regions including the Black Sea. However, US wheat export sales remain weak overall at 9.737 MMT, 31% below last year and behind the average pace.
Better US Weather Brings Harvest Back Into Focus
Much of the US Midwest was dry over the weekend after heavy September rainfall delayed fieldwork. Favorable harvest conditions are now expected to continue into mid-October, allowing corn and soybean harvesting to accelerate.
Corn harvest is expected to reach around 28% complete, close to the five-year average of 29%, while soybean harvest is estimated near 30%, still below the five-year average of 35%. Reports of mold and disease issues in areas affected by last week’s heavy rains are providing some support to soybeans, but faster harvest progress should gradually increase physical supply.
Soybean Demand Is Strong, but China Is Temporarily Quiet
US soybean export commitments remain one of the strongest demand signals in the complex. Total commitments have reached 22.236 MMT, up 89% from the same period last year.
Near-term Chinese demand is likely to remain quiet, however, with China on holiday until Thursday. Estimated Chinese purchases of US soybeans are just above 14 MMT. The market is therefore balancing strong existing export commitments against improving harvest conditions and limited fresh Chinese activity early this week.
Corn Recovers, but Export Pace Remains a Constraint
Corn is recovering modestly after last week’s sharp decline, but demand remains a concern. Total US export commitments stand at 18.774 MMT, down 31% year over year and eight percentage points behind the five-year average sales pace.
Managed money also reduced its net long corn position by 36,600 contracts, leaving the position at roughly 378,000 contracts. The next major fundamental catalyst comes Friday, when USDA will publish updated production and balance-sheet estimates.
Wheat Futures
Dec ’26 Chicago wheat is up $0.10 1/2 at $6.93 1/2/bu. Dec ’26 Kansas City wheat is up $0.11 at $7.46/bu, while Dec ’26 Minneapolis wheat is up $0.08 3/4 at $7.06 3/4/bu. Renewed Black Sea disruption, weaker Ukrainian exports and the large Saudi tender are providing the main support.
Corn Futures
Dec ’26 corn is up $0.02 1/4 at $5.00/bu. Support is cited at $4.88, with near-term resistance at the 50-day moving average of $5.07 1/2. Improving harvest weather and weak export commitments limit the rebound ahead of Friday’s USDA update.
Soybean Futures
Nov ’26 soybeans are up $0.10 1/4 at $12.88 1/2/bu, trading above Friday’s high. Dec ’26 soybean meal is steady at $347.50, while Dec ’26 soybean oil is up more than $0.01/lb and trading near a three-week high around $0.70/lb. Crop-quality concerns and strong export commitments are supportive, although improving harvest conditions and temporarily quieter Chinese demand could limit gains.
