With managed money shorts in Chicago wheat at a fresh record and corn printing new contract lows at the open, the path of least resistance remains down until Thursday's USDA data offers a potential reset.
The grain complex enters Monday's session under modest but broad pressure, with most contracts trading 2 to 3½ cents lower at the open. Higher energy prices provide a degree of underlying support across the complex, but a favorable US weather outlook and an unprecedented wave of speculative selling documented in Friday's CFTC data are more than enough to cap any early recovery attempt. Thursday's USDA supply-and-demand update is the next major scheduled catalyst, with traders expecting few significant revisions to either old- or new-crop stocks.
Record Managed Money Short in Chicago Wheat Sets the Tone
Friday's CFTC Commitment of Traders release confirmed what the price action already suggested: managed money added 39,165 contracts to their net short in Chicago SRW wheat futures and options in the week ending June 2, the largest single-week bear move on record going back to 2006, bringing the net short to 57,871 contracts. The morning outlook notes that continued selling in the second half of last week has since pushed the CGO wheat managed money short back above 70,000 contracts. In Kansas City, specs trimmed their net long by 13,393 contracts to 13,477. With the professional money community positioned this aggressively short, any rally attempt in Chicago wheat faces immediate overhead supply from funds defending or adding to positions.
Corn Prints a New Contract Low at the Open; Dec-26 at 10-Month Low
Jul '26 corn opened at $4.15½, down 2 cents, marking a new contract low at the start of Monday's session. Dec '26 opened at $4.44, also down 2 cents and at a 10-month low. A weekly bar chart gap from September 2025 remains unfilled and would require July to trade down to $4.05¼ to close — a level that now sits within technical reach given the current momentum. Open interest on Friday rose 9,025 contracts despite the Goldman Roll pulling July down 31,039 contracts and lifting September by 7,685, suggesting net new selling entered the market even as the roll compressed headline figures. The weight of fund liquidation — a 90,422-contract reduction in the managed money net long as of June 2, now 20 cents ago — continues to define the market's trajectory.
Favorable US Weather Removes Risk Premium Across the Complex
Widespread rains moved across the Central Midwest over the weekend, with lighter totals for the far Western Corn Belt. The NOAA 7-day forecast calls for 1 to 4 inches of precipitation across much of the Central and Eastern Corn Belt, as well as parts of Kansas and Missouri, with the heaviest totals concentrated in a band from eastern Kansas through central Missouri, eastern Iowa and Wisconsin, and much of Illinois and Indiana. Above- to much-above-normal temperatures are expected across the nation's midsection. This combination of adequate moisture and warmth supports crop development and actively erodes the weather risk premium that had been partially supporting corn and soybean prices, limiting any potential upside intraday.
Brazil Second Crop Corn Harvest Begins; Estimate Trimmed Slightly
AgRural estimates Brazil's second crop corn harvest at 4.4% complete, with their full second-crop production estimate revised down 0.9 MMT to 108.2 MMT. While the downward revision is modest, the key near-term market implication is the volume of South American supply that will begin competing with US corn exports over the coming weeks. Any acceleration in harvest pace or logistics improvement out of Brazilian ports would add further pressure to US FOB competitiveness. For now, the harvest is in its early stages and the size estimate remains large in absolute terms.
Argentina Corn Harvest Resumes After Weekend Rains
Weekend rains in Argentina provided temporary moisture but are not expected to materially delay the remaining corn harvest, with a drier outlook forecast for this week. This is a bearish signal for corn — it removes a weather-related disruption story that might have provided short-term support, and it signals that Argentine harvest pressure on world markets will continue without interruption. For soybeans, the drier Argentine week ahead is largely a non-event since the soy harvest is already well advanced.
Ukraine Wheat Crop Estimate Raised; Black Sea Infrastructure Holds
Ukraine's APK-Inform raised its wheat crop estimate by 1.8 MMT to 21.7 MMT, a supply-positive revision that adds to the bearish wheat narrative at a time when the market is already carrying record managed money shorts. Separately, Russian media reported that the Novorossiysk Grain Plant in the Sea of Azov and Black Sea area is operating normally despite Ukrainian drone attacks over the weekend. The absence of a logistics disruption removes a potential short-covering catalyst — had the facility been damaged, it could have triggered a sharp squeeze against the record short position. Instead, the Black Sea corridor remains functional, keeping export flow intact and limiting upside.
US Wheat Export Commitments Running 26% Below Year-Ago Levels
USDA's latest weekly Export Sales data showed new-crop wheat commitments at 3.925 MMT, down 26.44% from the same week last year. A South Korean importer did purchase 19,500 MT of US wheat in a tender late last week, but the transaction is too small to meaningfully offset the structural demand deficit relative to last year's pace. Until export commitments begin closing that gap, the physical demand picture reinforces the case for sustained fund short positioning rather than providing a floor.
Thursday USDA Report Is the Next Pivot Point for Corn and Soybeans
The morning outlook flags Thursday's USDA monthly supply-and-demand update as the session's primary forward-looking anchor. For corn, old-crop ending stocks are expected to hold near 2.142 billion bushels, with a 25-million-bushel increase in exports potentially offset by lower ethanol usage — a broadly neutral outcome. For soybeans, stocks are expected to remain near 340 million bushels with no changes to production estimates. With no significant surprises expected, Thursday's data may serve more as a confirmation of the bearish backdrop than a bullish catalyst, keeping downside risk as the dominant theme through mid-week.
Wheat
CGO Jul '26 CBOT SRW wheat opened unchanged at $5.80, with KC Jul '26 starting the session at $6.25¾, up 5 cents, and MPLS Jul '26 at $6.21½, up 2 cents. The mixed open reflects the split between soft and hard red contracts that has characterized recent sessions. Both CGO and MPLS July contracts slipped to 3-month lows before recovering to current levels, while KC outperforms on the day. The dominant overhead pressure remains the record managed money net short in Chicago, which the morning outlook now estimates has grown beyond 70,000 contracts as of late last week.
Corn
Jul '26 CBOT corn is trading at $4.15½ at the start of Monday's session, down 2 cents and at a new contract low. Dec '26 is at $4.44, also 2 cents lower and at a 10-month low. Friday's close was $4.17½, down 7 cents, and the cumulative two-week decline in July now stands at 45 cents — a move driven by mass fund liquidation, a wetter Corn Belt forecast, the absence of fresh China demand, and softening world FOB competition as South American supplies come online. A weekly chart gap at $4.05¼ in July remains the next technical reference point to the downside. Thursday's USDA update is expected to bring minimal changes to stocks.
Soybeans
Jul '26 CBOT soybeans are trading at $11.16½ at the open, down 5 cents and at a fresh 4-month low. Nov '26 is at $11.34½, off 3 cents and at a 3-month low. Friday's close was $11.21½, down 8 cents. Jul '26 soymeal is down $1.80 at $306.70, also at a 4-month low, while Jul '26 soy oil is 52 points lower at 73.60. Board crush margins have collapsed further overnight, off another 2½ cents to $3.70/bu after shedding 27 cents on Friday alone. A heavy NOAA precipitation forecast across the Central and Eastern Corn Belt, lagging export commitments running 18% below year-ago levels, and continued spec fund de-risking frame the bearish start to the week.
