President Trump's electronic signature on the Iran-US memorandum of understanding at a Paris state dinner has removed the last pillar of geopolitical support from the grain complex, sending wheat back below $6.10 and soybeans to their weakest point of the week despite a string of fresh export sales.
Thursday's session is unravelling Wednesday's rally with notable precision. All three crops are lower at midday, with the proximate cause a clear macro regime shift: the Iran-US peace MOU signed overnight establishes a 60-day ceasefire, opens the Strait of Hormuz in exchange for a US lifting of its blockade on Iranian ports, and provides a 60-day window to negotiate a permanent agreement. That framework removes the geopolitical risk premium that had powered Wednesday's double-digit gains in wheat and provides crude oil with a clear path lower. Soybeans are the session's weakest crop despite back-to-back days of fresh Chinese and unknown-destination export sales, as soy oil extends its collapse and crush margins plunge to their lowest level since early February.
Iran-US MOU Signed: Strait of Hormuz Opens, Geopolitical Premium Exits the Complex
The memorandum of understanding formalises a 60-day ceasefire framework and reopens the Strait of Hormuz in exchange for the US lifting its blockade on Iranian ports, with the 60-day window explicitly designed to allow time to negotiate a permanent peace agreement. For grain markets, the implications are straightforward and negative: the risk premium that drove wheat's 16¾-cent surge on Wednesday was built on Black Sea disruption risk, energy supply uncertainty, and speculative short-covering in a market primed by a 72,000-contract net short. With the Iran catalyst now formally resolved, the rationale for that short-covering evaporates. Crude oil is responding accordingly, extending its decline toward the $77 area and pulling soy oil and ethanol economics with it. The 60-day temporary nature of the MOU means the geopolitical risk has not permanently disappeared, but the market will price a period of relative stability until further developments.
Wheat Funds Return to the Sell Side After Four Sessions of Net Buying
Coming into Thursday, speculative traders had been net buyers of Chicago SRW wheat for four consecutive sessions, trimming the managed money net short from the 79,407-contract record extreme of June 9 down to approximately 65,000 contracts. Wednesday's 16¾-cent rally was the direct product of that short-covering combined with fresh geopolitical and weather catalysts. Thursday is a clear reversal: funds have returned to the short side at midday, with CGO July at $6.02½, down 10¼ cents. Chicago's 50-day moving average at $6.18¼ acted as the precise ceiling — Thursday's early strength peaked exactly at that level before reversing, providing a textbook technical rejection. KC HRW July is down 11 to 12 cents at midday, having consolidated between its 50 and 100-day moving averages throughout the session before failing. MPLS spring wheat is down 5 to 6 cents, with Thursday's MIAX July failure also occurring after trading into a two-week high — all three classes failing at technical resistance simultaneously is a clear-cut bearish signal.
Algeria's Purchase Confirmed at $264–$265/MT — From Black Sea and EU, Not US
Wednesday's major demand news is now confirmed with sourcing details: Algeria purchased between 800,000 and 850,000 MT of milling wheat at $264–$265/MT CF for August 2026 shipment, with the grain almost certainly sourced from Black Sea and EU origins rather than the US. This is a direct and pointed illustration of the US export competitiveness problem — a purchase of nearly one million metric tonnes at current prices went entirely to competing origins. US new crop wheat commitments at 183 million bushels represent 24% of the USDA export forecast, fractionally above the 22% historical average pace, but the year-over-year trajectory tells the fuller story: commitments are running 21% below the same week last year against a USDA forecast calling for only a 15% annual decline. The export pace needs to accelerate substantially in the second half of the marketing year to meet even the downwardly revised USDA target, and Algeria's routing to the Black Sea confirms that US origin is not yet price-competitive enough to capture headline tender business.
Export Sales: Corn at a Four-Week High, Soybeans Beat Estimates, Wheat In-Line
Thursday's weekly Export Sales report delivered a differentiated reading across the three crops. Corn old crop sales of 1.157 MMT for the week of June 11 hit a four-week high and came in 28% above the same week last year, with notable buyers including Japan at 18 million bushels, Mexico at 16 million bushels, and Spain at 10 million bushels. Old crop corn commitments now stand at 3.304 billion bushels, up 26% year-over-year versus the USDA forecast calling for a 16% increase, representing 99% of the USDA projection against the 93% historical average — the strongest demand position in the complex. For soybeans, old crop sales of 424,869 MT exceeded the trade expectation range of 100,000 to 300,000 MT and marked a 12-week high, though commitments remain 11.71% below year-ago levels. Wheat new crop sales of 400,844 MT for 2026/27 were within the expected range, with commitments down 6.16% from the same week last year. Additionally, USDA announced flash sales of 285,775 MT of corn to Mexico, 132,000 MT of soybeans to China, and 120,000 MT of soybeans to unknown destinations for 2026/27 shipment.
Soybean Crush Margins Plunge to Lowest Since February; Soy Oil at a Seven-Week Low
Crush margins fell another 19 cents Thursday to $3.06½/bu — the lowest level since early February — with bean oil's price value declining to 53.6% of the crush. July soy oil extended its multi-day collapse by another 205 to 215 points, though it found technical support near its 100-day moving average at 68 cents per pound, which coincides with a 38% Fibonacci retracement level. July soymeal broke below $300/ton for the first time since early February, a psychologically significant level that will attract attention from both processors evaluating whether to forward-sell crush and end-users watching for value-buying opportunities in meal. At $3.06½, crush margins have now fallen nearly $1.25/bu from their peak earlier this month — a collapse that will eventually trigger production responses from processors, but at current energy and feedstock price levels does not yet provide a stabilising floor.
China Books Soybeans Again — But the Structural Math Remains Daunting
Two fresh Chinese and unknown-destination soybean purchases were announced Thursday morning — 132,000 MT to China and 120,000 MT to unknown, both for 2026/27 — following Wednesday's 372,000 MT combined booking. New crop soybean commitments have jumped to 49 million bushels, a three-year high and up 12% year-over-year. While the consecutive days of Chinese purchasing is the most positive demand signal for soybeans in several weeks, the structural arithmetic remains challenging: US Gulf FOB offers are back to a slight premium over Brazil through the nearby, and at a 5 to 10 cent discount for September-October — the window when US origin needs to be competitive to capture the bulk of its annual Chinese business. If the US is to reach 25 MMT of soybean sales to China ahead of Brazil's early-year harvest, weekly sales will need to average nearly 1 MMT per week from this point. At the current pace, that target is aspirational rather than on track.
Corn Export Pace Running Well Ahead of USDA Forecast; Drought Acres at Nine-Month Low
Corn's export picture is the clearest bright spot in Thursday's data. Old crop commitments at 3.304 billion bushels are running 26% above year-ago versus the USDA's 16% forecast increase, and at 99% of the USDA projection they are 6 percentage points ahead of the historical sales average of 93%. New crop corn sales of 519,035 MT for the week brought the new crop total to 4.643 MMT, a four-year high and 41% above year-ago levels. US corn acres in drought also fell 1 percentage point to 23%, marking a nine-month low and confirming that Midwest soil moisture conditions are adequate to support the crop through its most critical development period. The corn complex is absorbing the energy headwind and the broader macro selloff better than either wheat or soybeans on a fundamental basis, with July at $4.15½ and the key support at $4.05 remaining intact — though spreads weakened on the session, suggesting the recovery is fragile.
Weather: Wet Midwest Continues to Favour Corn and Soybeans, Pressure SRW Quality
The NOAA 7-day forecast shows the heaviest precipitation totals shifting toward the Western Corn Belt in the coming week, with weekend rains expected across Nebraska and Kansas before spreading into Iowa and Missouri, and late-weekend and early next-week rainfall along the I-states corridor through Ohio. For corn and soybeans, this moisture pattern is broadly supportive of crop development and keeps the weather risk premium minimal. For SRW wheat, the central and southern Midwest rainfall continues to threaten harvest quality and delay field operations for the portion of the crop still standing — the same dynamic that drove Wednesday's rally and that remains a legitimate fundamental support factor for Chicago wheat even as the geopolitical and speculative catalysts unwind.
Wheat
Jul '26 CBOT SRW wheat is at $6.02½ at Thursday's midday, down 10¼ cents, having peaked at the 50-day moving average of $6.18¼ in early trade before the geopolitical de-risking took hold. KC HRW July is down 11 to 12 cents at midday, having consolidated between its 50-day and 100-day moving averages without breaking higher, while MPLS spring wheat is down 5 to 6 cents after an early two-week high attempt failed. The session represents a direct reversal of Wednesday's momentum: the Iran-US MOU removes the geopolitical short-covering catalyst, the fund net short has rebuilt to approximately 65,000 contracts with traders clearly in a selling mood at midday, and Algeria's 800,000 to 850,000 MT purchase routed to the Black Sea and EU confirmed that US origin is not yet competitive enough to capture major tender business. New crop export commitments at 183 million bushels are running 21% below year-ago levels against a USDA forecast of only a 15% annual decline.
Corn
Jul '26 CBOT corn is at $4.15½ at Thursday's midday, down 5½ cents, with the CmdtyView national average cash corn price down 5½ cents to $3.84½. Support at $4.05 — the September 2025 weekly chart gap — remains intact and is the critical technical level into the close of the week's last session before Friday's Juneteenth holiday. The session's macro-driven weakness masks genuinely strong underlying fundamentals: weekly old crop sales of 1.157 MMT hit a four-week high and were 28% above year-ago, a flash sale of 285,775 MT to Mexico was announced this morning, new crop commitments at 4.643 MMT are 41% above the same point last year and at a four-year high, and corn acres in drought fell to a nine-month low at 23%. The ethanol data showing production running below the pace required to reach the USDA estimate is the persistent structural drag on demand, but it is largely offset by the export outperformance.
Soybeans
Jul '26 CBOT soybeans are at $11.22¼ at Thursday's midday, down 9¾ cents, with the CmdtyView national average cash bean price down 9 cents to $10.70. Jul '26 soymeal has broken below $300/ton for the first time since early February, down $4.90 to $5.10, while Jul '26 soy oil is down another 205 to 215 points, finding tentative support near the 100-day moving average and 38% Fibonacci retracement near 68 cents per pound. Crush margins have collapsed to $3.06½/bu, down nearly $1.25 from their June peak. Despite back-to-back days of fresh demand — 132,000 MT to China and 120,000 MT to unknown announced this morning, following Wednesday's 372,000 MT — weekly export sales of 26.5 million bushels at the high end of expectations and a 12-week high in old crop bookings at 424,869 MT, the soy complex is being overwhelmed by the energy decline, ANEC's Brazilian June export forecast raised to 15.3 MMT, and the structural constraint that China's 10% reciprocal tariff limits fresh buying to state-owned entities. The path to 25 MMT of US soybean sales to China requires weekly bookings averaging nearly 1 MMT from this point — a formidable target given the current tariff and competitive landscape.
