A broad and vicious liquidation event is unfolding across the grain complex on Thursday as collapsing soy oil simultaneously removes the last bullish pillar supporting soybeans, while corn breaks through $4.00 cash and wheat prints its second consecutive week of catastrophic old-crop cancellations.
The grain complex is in full liquidation on Thursday's midday — soybeans down 29 to 31 cents in what is shaping up as the worst single-session loss in 2026 for the front-month contract, corn down 8 to 9 cents with cash prices breaking below $4.00 for the first time to $3.88 1/4, and wheat down 6 to 7 cents with old-crop Export Sales printing a fresh marketing-year low on net cancellations of 642,239 MT. Soy oil is collapsing 220 to 250 points — fully reversing the Iran-Kuwait escalation premium that had been soy oil's primary support — while soymeal falls $8.50 to $9.00. The source describes corn's price action directly as a "death spiral liquidation," and the convergence of negative data across all three crops leaves no sector of the complex as a relative safe haven.
Soy Oil Collapses 220-250 Points — Biofuel Premium Obliterated as Iran Ceasefire Resumes
The single most important driver of Thursday's session is soy oil's 220 to 250 point collapse — the mirror image of Tuesday's and Wednesday's new contract highs. The Iran-Kuwait escalation that had pushed soy oil to record levels appears to have been followed by resumed ceasefire talks, removing the energy premium that had been the primary fuel for the vegetable oil rally. When soy oil loses its upward momentum, soymeal cannot compensate: soymeal is simultaneously falling $8.50 to $9.00, leaving the entire soy complex with no bullish anchor. The within-complex divergence that defined the last two weeks — soy oil up, soymeal flat — has now collapsed into a synchronised selloff where both products are falling hard. This is the most decisive single-session soy complex event since the Iran conflict began, and its directional implication is unambiguous: the biofuel-driven floor under soybeans has been tested and partially broken.
Old-Crop Wheat Export Sales Print Second Consecutive Marketing-Year Low at Net Cancellations of 642,239 MT
USDA's Export Sales report for the week of May 28 showed old-crop wheat net cancellations of 642,239 MT — the second consecutive week of marketing-year low performance and well below even the low end of estimates of 200,000 MT in net reductions. The source notes that some of the old-crop cancellation was likely rolled to new-crop, which recorded 838,507 MT — exceeding the top end of the 250,000 to 600,000 MT estimate range. The roll dynamic means the headline old-crop cancellation number partly reflects a timing decision rather than a pure demand failure, but the pattern of two consecutive marketing-year lows in old-crop confirms that US wheat origin competitiveness remains severely compromised heading into the final weeks of the marketing year. IKAR's maintained 91.5 MMT Russian crop estimate and 47.5 MMT export projection for 2026/27 keep the supply pressure fully intact.
Corn's Old-Crop Sales Miss Low End of Estimates; Cash Prices Break Below $4.00
Old-crop corn export sales of 883,332 MT for the week of May 28 came in below the low end of the 0.9 to 1.5 MMT estimate range, falling 13% from the prior week and 6.3% below year-ago. New-crop sales of 243,716 MT were within the 100,000 to 600,000 MT estimate range but represent a three-week low for 2026/27 business. The combination of the export sales miss and the continuing weather-improvement narrative has pushed Jul '26 corn to $4.22 3/4 — down 8 3/4 cents — while the national average cash corn price breaks below $4.00 to $3.88 1/4, a psychologically and commercially significant threshold. Brazil's May corn exports of 250,449 MT — well above the 38,928 MT shipped in May 2025 — add a direct competitive supply confirmation that is helping to explain the poor US sales pace.
Brazilian Corn Exports Surge Year-on-Year; Soybean Exports Also Above Year-Ago
Brazil's trade ministry data confirmed May corn exports of 250,449 MT — a multiple-fold increase from the 38,928 MT exported in May 2025 — directly demonstrating that Brazil is now shipping corn into the same destination markets that US origin was competing for. Brazil's soybean exports in May totalled 14.825 MMT, above the 14.099 MMT from May 2025 and confirming that the Brazilian supply pipeline remains active and competitive. These data points validate the structural narrative that has underpinned the grain complex's decline over the past several weeks: South American supply abundance and aggressive export pacing are structurally bearish for US export programme competitiveness in both corn and soybeans, and the Thursday sales data confirms that the physical market is reflecting this through deteriorating US booking activity.
Weather Forecasts Shift East — ECB Getting Precipitation Over Seven-Day Horizon
The weather forecast has shifted relative to Wednesday's outlook: the Eastern Corn Belt (ECB) is now expected to receive some precipitation over the next seven days — partially addressing the dryness concern that had been cited as the one zone of the US growing area not benefiting from the Western Belt rainfall. The shift is directionally significant because the Eastern Belt was the only potential weather risk area the market had been flagging. As the ECB forecast improves, the last remaining source of domestic crop weather premium in the complex is being removed. Above-normal temperatures remain in the northern Midwest, but with sufficient precipitation now expected across both belts, the 80% El Niño probability and the favourable broader weather pattern reinforce the view that the 2026 US corn and soybean crops are establishing well without meaningful current stress.
Colombia Corn Tender and New-Crop Soybean Sales Provide Thin Demand Reassurance
USDA announced a private export sale of 115,000 MT of corn to Colombia for 2026/27 shipment — a routine commercial purchase that adds near-term demand texture but is insufficient to provide directional support in Thursday's liquidation environment. New-crop soybean sales of 243,000 MT were at the higher end of the 60,000 to 300,000 MT estimate range, and bean meal sales of 231,752 MT came in at the low end of the 200,000 to 600,000 MT estimate. These numbers confirm that the demand programme for 2026/27 remains open and booking, but the pace is insufficient to counter the bear case at this stage of the marketing year. Old-crop bean oil sales of just 27 MT — falling in the middle of the estimated net reductions of 5,000 MT to 16,000 MT — are consistent with the broader biofuel demand story losing its grip on the soy complex Thursday morning.
Technical Picture: Lower Lows Across All Three Crops for Double-Digit Consecutive Sessions
The technical picture across all three crops has deteriorated significantly. The source describes corn's price action explicitly as a "death spiral liquidation," with Jul '26 corn having made lower lows in what is now a sustained multi-week breakdown sequence. Jul '26 wheat at $5.80 3/4 is at its lowest since 2024. Jul '26 soybeans at $11.23 3/4 — with national average cash beans at $10.64 1/4 — are approaching territory where physical demand and crush economics should begin to generate buying interest, but the synchronised soy oil and soymeal collapse is preventing the complex from finding a technical floor today. With the WASDE on June 11 approaching and no confirmed China buying, no ceasefire resolution, and Brazilian supply continuing to flow competitively, the market is pricing a bearish macro alignment rather than individual crop fundamentals.
Wheat
Jul '26 CBOT wheat is at $5.80 3/4, down 6 1/2 cents at Thursday's midday — a 12th new session low in 13 trading days and the lowest close for the July contract in an extended period. Old-crop Export Sales net cancellations of 642,239 MT — the second consecutive marketing-year low and below every pre-release estimate — confirm the physical origin competitiveness failure. New-crop sales of 838,507 MT exceed the estimate range top, providing the one constructive data point. KC HRW is 4 to 5 cents lower and MPLS spring wheat is 4 to 7 cents lower. IKAR's 91.5 MMT Russian crop and 47.5 MMT 2026/27 export estimate maintain the supply-side ceiling on any rally attempt. The approaching WASDE on June 11 and the trajectory of HRW harvest progress are the next two catalysts that could establish whether a technical floor is near.
Corn
Jul '26 CBOT corn is at $4.22 3/4, down 8 3/4 cents at Thursday's midday — the national average cash corn price breaking below $4.00 to $3.88 1/4 for the first time in this down-move. Old-crop export sales of 883,332 MT missed the low end of estimates, were 13% below the prior week, and 6.3% below year-ago. Brazil's May corn export surge from 38,928 MT year-ago to 250,449 MT provides direct empirical confirmation of competitive supply displacement. Colombia's 115,000 MT flash sale adds routine demand continuity. The ECB precipitation forecast improvement removes the last domestic weather support. The source does not provide an official closing price for corn — the midday figure of $4.22 3/4 is the current start-of-day reference.
Soybeans
Jul '26 CBOT soybeans are at $11.23 3/4, down 30 1/4 cents at Thursday's midday — the worst single-session loss of 2026 for the front-month contract. Soy oil is down 220 to 250 points, fully reversing the Iran-Kuwait escalation premium from Wednesday; soymeal is down $8.50 to $9.00. National average cash beans at $10.64 1/4 are approaching levels not seen in this marketing year. Old-crop sales of 276,852 MT were a three-week low but 42.45% above year-ago. New-crop sales of 243,000 MT were at the high end of estimates. Brazil's May soybean exports of 14.825 MMT above year-ago confirm supply availability. With soy oil's biofuel premium collapsing and soymeal finding no independent bid, the complex has no remaining bullish pillar until China demand confirmation or a material weather event restores it.
