Grain Markets Start the Week With Weather, USDA, and Livestock Pressure in Focus

Early Monday grain trade is starting with a firmer tone in corn and soybeans and a more mixed wheat board. December 2026 corn was quoted at 466.25 cents per bushel, up 5.25 cents, in a delayed MarketWatch quote updated at 7:44 a.m. CDT on July 13. November 2026 soybeans were quoted at 1,194.50 cents per bushel, up 3.75 cents, in a delayed MarketWatch/WSJ quote updated at 7:44 a.m. CDT. September 2026 Chicago wheat was quoted near 637.00 cents per bushel, down 3.25 cents, in a delayed WSJ quote updated at 7:44 a.m. CDT.

Corn's main support this week is the tighter post-WASDE balance sheet and a weather market that is moving into pollination. USDA left the national corn yield unchanged at 183 bushels per acre in the July WASDE, while raising production to 16.0 billion bushels. USDA also cut new-crop corn ending stocks from 1.960 billion bushels in June to 1.790 billion bushels in July. That combination matters because the market is now balancing a large crop forecast against stronger use and a smaller carryout cushion than traders had in June.

Weather is the second major corn factor. USDA's last Crop Progress update showed 67% of the corn crop rated good to excellent as of July 5, steady with the prior week but below last year's 74%. Corn silking was 16% as of July 5, slightly ahead of the five-year average of 14%, which puts more acres into the sensitive pollination window during mid-July. NOAA's Weather Prediction Center said Monday morning that a strong upper-level high was building eastward across the northern tier, with triple-digit highs expected across the northern Plains and heat spreading into the upper Midwest. For corn growers, that makes this afternoon's USDA Crop Progress report especially important because it will be the first broad condition read after the latest heat and storm pattern.

Soybeans are also being pulled between supportive demand numbers and a still-watchable crop. USDA left the soybean yield unchanged at 53 bushels per acre and raised production to 4.475 billion bushels in the July WASDE. USDA left new-crop soybean ending stocks unchanged at 310 million bushels. The old-crop and new-crop soybean carryout numbers were described by Agriculture of America as below pre-report expectations, while USDA's production increase was modest.

The soybean crop entered last week in decent but not perfect shape. USDA said 64% of soybeans were rated good to excellent as of July 5, down one point from the previous week and two points below the prior year. USDA also reported 34% of soybeans blooming and 9% setting pods as of July 5, both ahead of their five-year averages. That means soybean traders will watch whether heat trims ratings or whether scattered rainfall keeps the crop moving through reproductive stages without major stress.

Wheat remains the most fundamentally different market of the three. USDA estimated 2026/27 wheat production at 1.536 billion bushels in July, down from 1.543 billion bushels in June. USDA lowered new-crop wheat ending stocks to 722 million bushels from 744 million bushels the prior month. The Wall Street Journal reported that USDA's 1.536-billion-bushel wheat production forecast would be the lowest U.S. wheat output since 1970.

The wheat story is not just production size; it is also crop quality and harvest pace. USDA said winter wheat harvest was 59% complete as of July 5, ahead of both last year and the five-year average of 51%. USDA rated only 26% of winter wheat good to excellent as of July 5, compared with 48% a year earlier. Spring wheat was rated 57% good to excellent, down from 59% the prior week. For growers with wheat to price, the market is dealing with a smaller U.S. crop, faster winter wheat harvest movement, and global headline risk at the same time.

Cattle markets are giving ranchers a different kind of signal. USDA ERS lowered its 2026 beef production forecast to 25.438 billion pounds and raised its 2026 slaughter steer price outlook to $250.16 per hundredweight. At the same time, Barchart reported that live cattle futures lost $1.05 to $1.30 on Friday, cash trade was quoted at $247 to $248 across the country, and the cash trade was $7 to $8 lower than the prior week. Barchart also reported the CME Feeder Cattle Index at $370.42 on July 9, down $4.03. The short version for ranchers is that USDA still sees tight beef production and high steer prices, but futures and cash weakened into the weekend.

The USDA calendar is busy enough to shape trade this week. USDA lists ERS Wheat Data, the Feed Grains Database, and Season Average Price Forecasts for 2:00 p.m. Eastern today, followed by NASS Crop Progress at 4:00 p.m. Eastern. USDA lists ERS Wheat Outlook, Oil Crops Outlook, and Feed Outlook for Tuesday afternoon. USDA also lists Slaughter Weekly and the Livestock, Dairy, and Poultry Outlook for Thursday afternoon.

For farmers, the practical takeaway is to keep basis, crop ratings, and weather forecasts tied together this week. Corn has support from a smaller carryout but still needs pollination weather to cooperate. Soybeans have a tighter-than-expected demand tone but are entering a crop stage where August weather will matter more with each week. Wheat has the clearest supply-side story, but harvest pressure and futures volatility can still complicate cash decisions. For ranchers, high USDA price expectations are still in place, but last week's weaker futures and cash trade argue for watching packer bids and feeder values closely before assuming the market is done correcting.
