Harvest Headlines
Corn Prices
Overnight futures rose modestly, with May contracts up 5.75 cents to $4.58 per bushel, tracking a broader grain upswing fueled by crude oil's 3.5% surge to $86.50 per barrel due to Middle East conflicts. This energy rally provided spillover support to corn, offsetting some bearish sentiment from recent price retreats. Traders are monitoring potential disruptions to global supply chains that could indirectly boost corn demand.
The USDA's latest Supply and Demand report showed little reaction in prices, as U.S. ending stocks held steady at a seven-year high of 2.127 billion bushels with no changes to exports or other categories. Globally, ending stocks increased to 292.75 million metric tons, down 1% year-over-year but still the lowest since 2014-15, reflecting downgraded demand. This balance sheet stability underscores ample supplies pressuring upside potential.
Brazil's corn crop estimate was raised by 1 million metric tons to 132 MMT, while Argentina's was cut by the same amount to 52 MMT, highlighting South American production shifts amid variable weather. Ukraine's forecast jumped nearly 6% to 30.7 MMT, adding to global abundance. These adjustments could influence U.S. export competitiveness through the second quarter.
Attention is turning to the March 31 Prospective Plantings report, where USDA initially forecast 2026 U.S. corn acres at 94 million, down almost 5% from 2025's nine-decade high. Farmer surveys may adjust this figure based on recent market volatility and external factors like war-related energy costs. Lower acres could tighten future supplies and support prices if realized.
The Energy Information Administration's weekly ethanol report is due today, following last week's production dip to 1.085 million barrels per day, a four-week low. Ethanol remains a key demand driver for corn, with recent figures showing a 1.6% weekly decline. Stronger output could bolster corn usage amid high U.S. stocks.
Geopolitical disruptions from the Iran conflict have tightened fertilizer supplies, pushing urea prices up 22% from late 2025 levels. Farmers are securing nutrients at elevated costs ahead of spring planting, potentially increasing production expenses. This could squeeze margins in a tight economy, indirectly affecting corn planting decisions.
National average cash corn prices fell over 1.25 cents to $4.0875, widening the basis to 43.5 cents below May futures from 40.75 cents a week ago. This indicates softer spot market demand. Upgrading equipment like old planters is recommended over new purchases to manage costs.
Soybean Prices
May futures surged 15 cents overnight to $12.1675, building on Tuesday's gains and marking the highest close since May 2024, though still below this week's 21-month intraday high of $12.3375. The rally was led by soyoil, which soared 221 points to 67.83 cents per pound amid crude oil's spike. November contracts rose 8.75 cents to $11.6225, reflecting sustained upward momentum.
Technical indicators strengthened, with prices maintaining a steep uptrend from mid-January lows and solidifying above $12 this week. Bulls are targeting $12.20 and potentially Monday's highs, with support at the 10-day SMA of $11.8325. Upside resistance looms at May 2024 highs around $12.58 on continuation charts.
Optimism for improved U.S. export demand from China buoyed prices ahead of Treasury Secretary meetings this weekend and a Trump-Xi summit in April. Recent routine purchases by China have focused on Brazil due to price advantages, but quality issues in Brazilian supplies and U.S. crush outlooks could extend demand windows. This geopolitical thaw could counter heavy South American supplies.
The USDA report was largely neutral, lowering Argentina's soybean harvest by 1% to 48 MMT due to dry February weather, while holding Brazil steady at a record 180 MMT. U.S. crushing was raised 5 million bushels to a record 2.575 billion, with exports at a 13-year low of 1.575 billion and ending stocks unchanged at 350 million, a six-year high. Soyoil biofuel use was cut 5.4% to 14 billion pounds.
Soybean meal futures dipped 90 cents to $313.60 per ton, contrasting soyoil's strength but still reflecting complex support. Prices could be capped by Brazil's ongoing record harvest, prompting U.S. farmers to sell remaining old-crop inventories. Heavy supplies remain a downside risk despite demand hopes.
National average cash soybean prices rose over 5.5 cents to $11.2725, with basis widening to 74.75 cents below May futures from 73 cents a week earlier. This suggests mixed spot demand. In a constrained economy, cost-saving strategies like equipment upgrades are advised.
Global ending stocks adjustments were minor, but ample supplies underscore bearish fundamentals limiting rallies. Traders are watching for any shifts in biofuel demand tied to energy volatility. Potential U.S.-China deals could provide a bullish catalyst.
Wheat Prices
March SRW futures rose 9 cents to $6.00, recovering from Tuesday's 12.25-cent drop and up nearly 13% from February lows around $5.32, though below this week's high of $6.4175. HRW contracts gained 10.25 cents to $6.19, and spring wheat added 1.25 cents to $6.3625. The rebound aligned with corn and soybeans on crude oil strength.
A dry forecast for the Southern Plains through month-end, amid ongoing drought, provided underlying support despite ample global supplies. This weather risk could impact yields in key regions. Geopolitical tensions adding to energy costs further bolstered the overnight uptick.
State crop ratings showed mixed winter wheat conditions, with Kansas at 56% good-to-excellent (down from 58%), Oklahoma improving to 24% (up from 19%), and Texas steady at 16%. Topsoil moisture in Kansas was 38% short or very short. Recent rains offered some relief, but drought expansion raises yield concerns.
Bearish fundamentals persist, with U.S. ending stocks unchanged at 931 million bushels, up 9% year-over-year and a six-year high, while exports held at 900 million, a five-year high. Average farm price rose 5 cents to $4.95 per bushel. Global production hit a record 842.12 MMT for the sixth straight year, up 5.2%.
Ending global stocks were trimmed 0.2% to 276.96 MMT, but ample supplies and eroding U.S. exports cap upside. The WASDE report reinforced these pressures, with minimal balance sheet shifts. Traders are eyeing potential war impacts on Black Sea flows.
Overnight gains were supported by broader grain and energy markets, but wheat remains vulnerable to supply abundance. Dry Southern Plains outlooks could spark short-covering. In a tight economy, focus on cost efficiencies like planter upgrades.
State-level variations highlight regional risks, with limited snow cover exacerbating drought effects. This could tighten domestic supplies if conditions worsen. Global competition from high production keeps export demand subdued.
Extended Commentary
Grain markets rebounded in overnight trading as a sharp rally in crude oil prices—triggered by escalating tensions in the Middle East—spilled over into the broader commodity complex. Soybeans led the advance, supported by strong gains in soyoil and renewed optimism surrounding potential U.S.–China trade discussions. The surge in energy markets boosted sentiment across grains, particularly for oilseed markets tied to biofuel demand, while corn and wheat followed higher despite lingering pressure from ample global inventories highlighted in the latest supply estimates.
Corn futures gained modestly as traders balanced supportive energy markets and ethanol demand prospects against comfortable supply levels. The USDA’s latest balance sheet changes were limited, leaving U.S. ending stocks near multi-year highs and reinforcing the narrative of abundant global supplies, particularly with strong South American production forecasts. Meanwhile, wheat prices recovered alongside the broader grain complex, aided by drought concerns in the Southern Plains, though record global production and steady domestic stocks continue to cap upside momentum. With fundamentals largely unchanged, market attention is shifting toward the March 31 Prospective Plantings report, ethanol production trends, and evolving geopolitical risks that could influence energy prices, fertilizer costs, and overall grain demand.
