A ninth straight day of US strikes on Iran, two American servicemen killed in Jordan, and a still-closed Kerch Strait are driving fresh buying across the grain complex, with soybeans posting the sharpest early gains on top of Friday's push to multi-year highs.

Grains open sharply higher Monday, extending Friday's rally as escalating Middle East and Black Sea conflict keeps a war premium firmly embedded across wheat, corn, and soybeans, with soybeans leading the charge on gains of 17 to 19 cents.

Middle East Conflict Escalates Further

The Middle East conflict has widened further over the weekend, and the market is no longer treating it as background noise. US military forces have carried out strikes against Iranian targets for nine consecutive days, while Iran has continued attacking US forces in the region, killing two American servicemen in Jordan and damaging a crude oil facility and power plant in Kuwait. Both the Strait of Hormuz and the Kerch Strait remain largely closed to vessel traffic, a dual chokepoint disruption that is keeping energy and Black Sea grain flows simultaneously constrained. Spot WTI crude is down $0.40 near $82.10 after trading above $85 for the first time in six weeks, with the pullback doing little to erase the underlying supportive tone that has carried through the energy complex and into biofuel-linked soybean oil.

Black Sea Attacks Turn Deadly for Grain Cargoes

Black Sea shipping risk shows no sign of easing either. Ukraine continues to attack Russian vessels in the Sea of Azov while Russia is launching strikes against Kiev and port infrastructure along the Black Sea, with Ukrainian officials reporting 10 people killed when a Russian missile struck a vessel carrying corn near the port of Odesa. That attack underscores the physical risk now facing outbound grain cargoes, not just the freight and insurance costs that have already been climbing, and continues to reinforce wheat's rally into the new week.

Friday's Close Confirms Broad-Based Strength

Friday's session confirmed the strength building beneath the surface. Chicago SRW wheat closed 4 3/4 to 9 1/2 cents higher, with Sept '26 finishing the week up 42 1/2 cents; KC HRW rallied 10 1/2 to 15 3/4 cents on the day with September up 56 cents on the week; and MPLS spring wheat gained 6 1/2 to 11 1/2 cents, with September up 39 1/4 cents for the week. Corn shrugged off early Friday weakness to close near session highs, up 2 1/4 to 3 1/2 cents, while soybeans rebounded from Thursday's losses with a late push of 4 1/2 to 9 1/2 cents, leaving August up 12 3/4 cents and November up 12 1/4 cents on the week.

Fund Positioning Turns Decisively Bullish

Managed money is now leaning firmly into the rally across the complex. Commitment of Traders data through July 14 showed funds slashing their CBOT wheat net short by 25,527 contracts to just 36,798, while adding 5,730 contracts to their KC wheat net long, now at 17,494; combined spec short wheat positioning has fallen to 25,000 contracts, the smallest in two months. In corn, managed money added 30,732 contracts to its net long, pushing it to 43,391, while soybean funds added a more modest 4,009 contracts to reach a 72,688-contract net long, part of an estimated combined ag-space long position that has grown to 253,000 contracts as of Friday's close.

Export Sales Running Ahead of USDA's Pace

Thursday's USDA Export Sales report reinforced a demand picture that is running ahead of pace across all three crops. Wheat's 2026/27 sales have reached 2.057 MMT as of July 9, already 10% of the USDA's export projection versus a 9% five-year average pace. Corn's old-crop sales total of 86.279 MMT is running at 102% of the USDA's export projection, ahead of each of the last three years, while new-crop sales of 6.859 MMT are 14.5% above the same point last year. Soybean old-crop sales have reached 41.324 MMT, matching the USDA's full projection already, with new-crop business now at 4.598 MMT.

South American Supply Keeps Building

South American harvest and production data continue to build a large supply base even as demand accelerates. Brazil's AgRural pegs the second corn crop at 49% harvested, lagging last year's 55% pace, while Safras & Mercado projects Brazil's 2026/27 corn crop at 144.96 to 145 MMT, up from 140.4 MMT this past season and above the USDA's own 139 MMT estimate. Argentina's corn harvest stands at 62%, well behind last year's 80% pace per the Buenos Aires Grain Exchange. On soybeans, Safras & Mercado raised its Brazilian 2026/27 crop estimate to 180.1 to 180 MMT, up from 178.3 MMT, with plantings seen rising half a percentage point to 49.1 million hectares, keeping the global supply cushion intact despite the harvest delays.

China Tilts Toward Brazil, Away From the US

China's demand picture is shifting decisively toward Brazil at the expense of the US. June imports of 13.55 MMT were largely sourced from Brazil, which supplied 12.1 MMT, up 14% from a year ago, while US-origin imports totaled just 1.27 MMT versus 1.6 MMT in June of last year. Year-to-date, US imports into China of 9.3 MMT are down 42.4% from last year, while Brazilian imports of 34.75 MMT are up 9%, a divergence that keeps US old-crop soybean competitiveness in the spotlight even as three separate private export sales hit the tape Friday: 340,000 MT to China, 256,634 MT to Mexico, and 110,000 MT to unknown destinations, all for new crop.

US Weather Stays Yield-Threatening

US weather is offering a mixed but still yield-threatening setup into the week. Weekend temperatures exceeded 100°F across northern Nebraska and South Dakota, with mid-to-upper 90s across much of the Northern Plains and Western Corn Belt, while scattered rain hit the central and Eastern Corn Belt but left the Western Corn Belt and Northern Plains largely dry. Temperatures across the Western Corn Belt should ease for three to four days before much-above-normal heat returns by next weekend, and while a system may bring scattered rain to the Western Corn Belt midweek, the NOAA 7-day QPF shows 1 to 2 inches confined mainly to Nebraska, Missouri, and parts of southern and eastern Iowa and western Illinois, leaving much of the broader Corn Belt without meaningful relief.

Wheat: Black Sea Risk and French Crop Cut Keep Bias Higher

CGO Sept '26 opens $0.02 higher at $6.84 3/4, KC Sept '26 is $0.02 3/4 higher at $7.35, and MIAX Sept '26 is $0.05 1/4 higher at $6.97, extending Friday's close of $6.82 3/4 for CBOT Sept '26, up 8 cents on the day and 42 1/2 cents on the week. Continued Black Sea supply disruption, a closed Kerch Strait, and Argus's cut to its French soft wheat production forecast to 30.8 MMT, a 7.6% drop from last year, are keeping the path of least resistance tilted higher with volatility elevated.

Corn: Seven-Week Highs on Exports and Fund Buying

Sept '26 opens $0.06 higher at $4.50 3/4 while Dec '26 is $0.07 higher at $4.74 1/2, both trading to their highest levels in seven weeks after Friday's close of $4.44 3/4 for Sept '26, up 3 1/4 cents on the day and 5 1/4 cents on the week. Strong export sales running well ahead of the USDA's pace, fresh managed-money buying, and a still-threatening US weather outlook are offsetting the slower-than-expected Brazilian second-crop harvest pace to keep corn firm into the session.

Soybeans: Fresh Flash Sales Push Contract to Multi-Year Highs

Aug '26 opens $0.15 1/2 higher at $12.20 while Nov '26 is $0.16 higher at $12.19, with August trading to a two-month high and November touching a three-year high, next resistance at the contract high of $12.41, after Friday's close of $12.04 1/2 for Aug '26, up 9 1/2 cents on the day and 12 3/4 cents on the week. Fresh Chinese and Mexican flash sales, record managed-money buying across the ag space, and continued biofuel-linked soybean oil strength are driving the early rally, even as China's shift toward Brazilian-origin beans keeps a longer-term question mark over US export competitiveness.
