President Trump's declaration that the Iran ceasefire is "over" following renewed Iranian strikes on Hormuz shipping has sent WTI to a 2½-week high and fractured the soy complex from the rest of the grain market — soy oil rallies sharply on the energy spike while corn and wheat absorb their own bearish pressures ahead of Friday's USDA supply-and-demand update.
Wednesday's session is defined by an extraordinary macro rupture: the Iran-US peace framework that had been a dominant downside force on energy for three weeks has collapsed overnight, with Trump revoking Iran's licence to sell oil globally and the US Treasury simultaneously unwinding the authorisation issued during the ceasefire period. The result is a fractured grain complex — old-crop soybeans and soy oil surging on the energy and geopolitical premium, new-crop soybeans under selling pressure, and corn and wheat both trading 7 to 8 cents and 2 to 8 cents lower respectively as they face their own structural headwinds ahead of Friday's WASDE.
Iran Ceasefire Declared Over: Crude at a 2½-Week High, Energy Economics Reverse
Trump's statement that the ceasefire with Iran is "over" — triggered by Iranian strikes against vessels transiting the Strait of Hormuz — marks the sharpest geopolitical reversal the energy and grain markets have experienced since the original escalation in June. Spot WTI is up $3.85 to near $74.25, a 2½-week high, with RBOB up $0.05 per gallon and heating oil up $0.12. The US Treasury simultaneously revoked Iran's licence to sell oil globally, removing the commercial framework for Iranian petroleum exports that had been the key mechanism enabling energy price suppression over the past three weeks. For the grain complex, the energy reversal has immediate and differentiated implications: soy oil's biodiesel economics improve directly with crude, providing the first genuine lift to that market in weeks; corn's ethanol margins recover modestly though the benefit is partially offset by today's EIA data showing another week of below-pace ethanol production; and wheat's relationship with energy is the most indirect, explaining why it is underperforming this morning despite the macro shift.
China Books 472,000 MT of US Soybeans This Morning — Second Major Purchase in Two Days
USDA announced a flash sale of 472,000 MT of US soybeans to China this morning — 136,000 MT for the 2025/26 marketing year and 336,000 MT for 2026/27. This follows COFCO's reported purchase of 300,000 to 600,000 MT earlier this week, making this the second consecutive confirmed Chinese booking in as many days. The cumulative two-day Chinese demand signal is the most commercially significant demand development for US soybeans in months and directly validates the competitive FOB positioning shift that has been building since June — US Gulf offers currently sit at a $0.10 to $0.20 premium over Brazilian bids through the November contract, confirming the structural window for US origin is open and being actively used. August soybeans are at $12.01¾ at the morning open, up $0.08, having stretched to a six-week high, while old-crop July has crossed above the psychologically critical $12.00 level to $12.02¼. The path of least resistance in soybeans is firmly higher with Chinese demand confirming and US weather uncertainty still elevated.
Old Crop-New Crop Spread Widens as July Soars and November Slips
The internal soybean market structure is telling a precise story this morning: front months are up 1 to 5½ cents while new-crop contracts are down 3 to 5 cents, creating an old-crop-new-crop spread widening that reflects two simultaneous but opposing forces. The front end is being lifted by confirmed Chinese demand for nearby delivery and the energy-driven soy oil rally. The back end is being capped by the Reuters poll expectation that Friday's WASDE will raise 2026/27 new-crop soybean stocks by 20 million bushels to 330 million, reflecting the higher acreage confirmed in Tuesday's acreage report. This spread widening is a technically healthy market signal — it distinguishes near-term supply tightness from longer-term acreage-driven supply growth — and is the precise dynamic that a well-functioning export-driven soybean rally should produce when demand materialises in the spot window.
EIA Ethanol Production Slips Again Below Required Pace
EIA's weekly update showed ethanol production of 1.093 million barrels per day in the week of July 3, down 24,000 bpd from the prior week. Ethanol stocks drew 762,000 barrels to 23.928 million barrels. Ethanol exports surged 74,000 bpd to 200,000 bpd — a positive demand signal — while refiner inputs fell 20,000 bpd to 901,000 bpd. The production figure was well below the pre-report expectation of 324 million gallons, with the actual figure continuing the streak of below-pace production that has been running for most of the past two months. Despite the July 3 holiday week skewing the data lower, the sustained production shortfall keeps the corn-for-ethanol demand assumption under pressure heading into Friday's WASDE, where analysts surveyed by Reuters expect lower corn stocks in both old and new crop. May monthly Census corn data provided an offsetting positive: corn exports of 7.252 MMT were the third largest May on record, ethanol exports hit a record 189.65 million gallons up 6.59% from last year, and distillers grain exports were the second largest May on record.
Wheat Retreats From Five-Week Highs; Friday's WASDE Expected to Cut Stocks 30 Million Bushels
The wheat complex is under moderate selling pressure at midday Wednesday — Chicago SRW contracts down 2 to 8 cents, KC HRW down 3 to 7 cents, and MPLS spring wheat off 2 to 3 cents — after the prior session saw CGO September trade to a five-week high of $6.22. This is a consolidation rather than a reversal: KC September at $6.52½ is still sitting just below resistance at $6.64½ and well above the 100-day moving average it broke through earlier this week. The Reuters WASDE survey projects US 2026/27 wheat ending stocks falling 30 million bushels to 714 million, with all-wheat production expected to drop 18 million bushels to 1.525 billion due to lower winter wheat, and the average winter wheat production forecast at 1.001 billion — a 29-million-bushel reduction from June's figure. Final Russian wheat exports for 2025/26 at 48 MMT were well above the 42.2 MMT shipped in 2024/25, a bearish supply-side data point that caps upside in Chicago and KC even as the domestic US supply story tightens. SovEcon trimmed their own Russian 2026/27 wheat production estimate 0.2 MMT to 46.5 MMT, providing only marginal offset.
May Census Corn and Soybean Exports Confirm Record-Level Demand Activity
Monthly Census export data for May provided a strong retrospective demand confirmation across both corn and soybeans. Corn exports of 7.252 MMT were the third largest May on record and near the 2020/21 record. Soybean exports of 2.57 MMT were the second largest May on record, 72.46% above last year's May shipments, with soybean meal exports setting an outright record at 1.572 MMT — 19.47% above May 2025. Corn ethanol exports at 189.65 million gallons were a record for May, 6.59% above last year. This data confirms that the export acceleration implied by the quarterly stocks miss — which showed record March-to-May corn usage — had genuine physical trade flows behind it. Thursday's Export Sales report will be the first current-marketing-year read on whether the pace is continuing through the first week of July, with analysts looking for 0.6 to 1.1 MMT of old-crop corn and 600,000 to 900,000 MT new crop.
Weather: Eastern Corn Belt Getting Rain, Western Corn Belt Heading Into Dry and Hot Window
Rainfall over the past 24 hours remains heaviest across the northern Midwest with scattered precipitation in the southern Midwest, Gulf coast, and Southeast. Over the next 7 days, NOAA's QPF shows 1 to 2 inches concentrated south of I-80 across most of Missouri, Indiana, Ohio, and the southern half of Illinois, with parts of eastern Nebraska, western Iowa, and central Wisconsin receiving up to an inch. The Eastern Corn Belt is receiving useful mid-pollination moisture. However, the Western Corn Belt is heading into a dry window with little to no precipitation across the Northern and Southern Plains. By late this weekend, the high-pressure ridge is expected to expand across the US Plains triggering much-above-normal temperatures — a pattern that will put the western portions of the Corn Belt under meaningful heat stress during the critical pollination period. World Weather's expectation remains that the ridge will shift west in the second half of July, eventually allowing cooler temperatures and rain to return to the eastern Midwest, limiting the duration of the premium.
US Equities Sharply Lower; Dollar Higher — Mixed Macro Signals
US stock indices are sharply lower Wednesday morning as the Iran ceasefire collapse introduces acute geopolitical uncertainty into financial markets, while the US dollar is moderately higher in two-sided trade. A stronger dollar is a mild competitive headwind for US agricultural exports — raising the cost of dollar-denominated US grain for foreign buyers — but the current move is not large enough to meaningfully offset the Chinese demand signals and weather premium supporting corn and soybeans. The equity selloff reflects broader risk-off sentiment that historically adds pressure to commodity longs, but in grain markets the weather and demand story is currently powerful enough to override the macro headwind for the crops most directly exposed to the US growing season.
Wheat
CGO Sep '26 CBOT SRW wheat is at $6.22 at Wednesday's open — the morning quotes show Sep up $0.03½ at $6.22 — having traded to a five-week high before midday selling pulled Chicago down 2 to 8 cents with Jul at $6.07¼, down 2 cents. KC Sep is at $6.58¾, up $0.06, stalling just below resistance at $6.64½, while MIAX Sep is at $6.39, also up $0.06. The morning strength is giving way to consolidation selling mid-session. The Reuters WASDE poll projects US 2026/27 wheat stocks down 30 million bushels to 714 million and all-wheat production down 18 million to 1.525 billion — cuts that, if confirmed Friday, tighten the domestic balance sheet further. May Census wheat exports of 1.609 MMT came in 26.7% below last year and 13.73% below April, while Russian 2025/26 final exports at 48 MMT well above the prior year underline why US wheat remains a price-taker on world markets despite the domestic supply tightening.
Corn
Jul '26 CBOT corn is at $4.35½ at Wednesday's midday, down 7 cents, with the CmdtyView national average cash corn price down 7½ cents to $4.05¼. Sep-26 is at $4.42¾ in morning trade, down just $0.01, having closed higher for five consecutive sessions, while Dec-26 is approaching the 50% Fibonacci retracement level at $4.66 with 50- and 100-day moving average resistance between $4.68½ and $4.73. The session's mid-range pressure reflects the EIA data showing ethanol production slip to 1.093 million bpd, down 24,000 bpd, below the required pace to meet the USDA's full-year estimate. May Census corn data provides the positive offset — third-largest May export on record at 7.252 MMT, record ethanol exports at 189.65 million gallons, second-largest distillers grain May on record. Thursday's Export Sales are expected to show 0.6 to 1.1 MMT of old-crop business with new crop 600,000 to 900,000 MT. Friday's WASDE Reuters poll anticipates lower corn stocks for both old and new crop with little change to this year's production.
Soybeans
Jul '26 CBOT soybeans are at $12.02¼ at Wednesday's midday, up 5½ cents, crossing above the $12.00 level for the first time since the record fund-selling began. Aug-26 is at $12.01¾, up $0.08 in morning trade — a six-week high — with November at $12.01, up $0.03¼ with resistance at the May high of $12.14. Aug-26 soy oil is up 133 points at 69.92, a three-week high, as the crude oil surge on Iran geopolitics directly lifts biodiesel economics. Aug-26 soymeal is down $3.00 to $4.20-5.60 lower across contracts. Crush margins at $2.58½, up $0.04. The USDA flash sale of 472,000 MT to China — 136,000 MT old crop and 336,000 MT new crop — on top of this week's earlier COFCO reported purchase confirms the Chinese demand activation the market has been waiting for since mid-June. The Reuters WASDE survey expects 2026/27 new-crop soybean stocks to jump 20 million bushels to 330 million on higher acres, capping the new-crop rally while leaving old-crop on a path of least resistance higher.
