November WASDE Tightens U.S. Grain Supplies as South American Competition Builds

The November 10 USDA World Agricultural Supply and Demand Estimates (WASDE) delivered a tighter outlook for U.S. corn and soybeans, with production and ending stocks coming in below market expectations. Yet global supply remains relatively comfortable, particularly as Brazil and Argentina prepare for another substantial growing season. Meanwhile, U.S. export demand, European sourcing constraints, biofuel policy, and the changing political landscape are adding complexity to agricultural markets. For U.S. producers, the immediate question is whether lower projected inventories can provide lasting price support. For international buyers, attention is shifting toward export availability, competing origins, and the development of South America's next harvest.

U.S. Corn: A Smaller Crop Provides Some Relief

After October's sharp upward revision to corn production and ending stocks, November's WASDE moved in the opposite direction. USDA reduced its 2026/27 U.S. corn production forecast from 16.034 billion bushels (407.3 MMT) to 15.893 billion bushels (403.7 MMT), reflecting a decline in the national yield estimate from 181.2 to 179.6 bushels per acre.

Projected ending stocks fell from 1.849 billion bushels (47.0 MMT) to 1.758 billion bushels (44.7 MMT), below the market's average expectation of 1.846 billion bushels (46.9 MMT). The reduction provides some relief following October's bearish supply revisions, although inventories remain substantial.

The demand side deserves equal attention. Stronger ethanol production and export sales can help absorb the large harvest, but the balance sheet still depends on sustained domestic use and international demand. Mexico remains an important destination, with USDA reporting additional corn sales of 312,700 MT on November 10, following several other large sales announcements earlier in the month.

Harvest conditions also remain uneven. As of November 8, the national corn harvest was 81% complete, compared with a five-year average of 86%. Iowa was only 72% harvested, against its historical average of 89%, as persistent rainfall restricted fieldwork. Delayed harvesting can increase drying and handling costs, adding pressure to farm margins even when national production estimates decline.

Global Corn Inventories Move in the Opposite Direction

Despite lower U.S. ending stocks, USDA increased projected global corn inventories from 280.4 MMT to 281.9 MMT. Larger stocks in China and Ukraine more than offset reductions elsewhere, leaving the global supply outlook somewhat more comfortable than the U.S. balance sheet suggests. USDA also raised corn production forecasts for Brazil and Argentina, adding to expectations of substantial export competition during 2027. U.S. prices will therefore depend not only on the final domestic crop size but also on export execution, competing origins and the amount of corn absorbed by feed and biofuel industries.

European Corn: Supply Constraints Extend Beyond Production

European corn markets face a different challenge. The EU's smaller 2026 crop and limited carryover supplies have increased procurement pressure, particularly for buyers requiring non-GMO corn. While the United States and Brazil have abundant exportable supplies, their predominantly genetically modified production may not meet European buyers' specifications. The November WASDE added another complication. USDA reduced its 2026/27 EU corn import forecast by 1 MMT to 22.5 MMT, and lowered Ukraine's corn export forecast by 2 MMT to 20 MMT. Ukraine is an important supplier to the European market, and reduced export availability could intensify competition for alternative origins.

These conditions offer a useful illustration of the risks associated with restricted sourcing options. The EU Deforestation Regulation (EUDR), which covers soybeans and several other agricultural commodities but not corn itself, introduces additional traceability and compliance requirements. Although the regulation addresses different products and objectives, European buyers could face similar procurement challenges if compliance requirements reduce the number of eligible suppliers or origins. The implications will depend on implementation, supplier readiness, and the availability of compliant supplies.

U.S. Soybeans: Lower Stocks, but Export Demand Remains the Test

USDA raised its U.S. soybean production forecast slightly, from 4.562 billion bushels (124.2 MMT) to 4.574 billion bushels (124.5 MMT), as the national yield estimate increased from 53.1 to 53.3 bushels per acre. Nevertheless, projected ending stocks declined from 315 million bushels (8.6 MMT) to 300 million bushels (8.2 MMT), below the trade expectation of 332 million bushels (9.0 MMT). The lower carryout provides a more supportive outlook for supply, but export demand remains a central uncertainty. China has resumed purchases of U.S. soybeans, including a reported sale of 136,000 MT on November 6, while USDA announced another 150,000 MT of soybean sales to Mexico on November 10. These transactions support near-term demand, but their cumulative volume and shipment execution will determine whether they materially change the season's export outlook. Domestic soybean processing remains another important source of demand. Strong crushing activity supports soybean disappearance, although processing profitability depends on both the soybean meal and soybean oil markets. Feed demand, biofuel policy, and the relative prices of competing vegetable oils and feedstocks will continue to influence the balance between crushing capacity and actual utilization.

Soybean Meal and Oil: Trade Flows Continue to Shift

Global soybean meal demand remains important to the U.S. crushing outlook, particularly as processing capacity expands. Additional domestic crush increases the availability of both meal and oil, making export competitiveness and domestic consumption essential to maintaining processing margins. Brazil's soybean oil trade provides an example of changing market relationships. Trade data through October indicate that India accounted for approximately 78% of Brazilian soybean oil exports during January–October 2026, compared with 72% in 2025 and 64% in 2024. China's share declined to nearly zero over the same period. Brazil's soybean oil exports reached approximately 1.9 MMT during the first ten months of 2026, compared with 1.3 MMT a year earlier. This concentration reflects India's growing importance as a destination for Brazilian soybean oil and increases Brazil's exposure to changes in Indian import demand and in vegetable oil price relationships. For the United States, soybean oil availability and prices remain closely linked to renewable fuel demand and competition from imported feedstocks.

South America: Larger Corn Forecasts, but Weather Risks Remain

USDA raised its 2026/27 corn production forecasts for both Brazil and Argentina by 2 MMT, to 141 MMT and 57 MMT, respectively. Brazil's first-season corn acreage is expanding, while the larger safrinha crop, planted after soybean harvesting, will remain the main determinant of total output. In Argentina, favorable soil moisture and reduced corn leafhopper pressure have encouraged planting, with some producers potentially allocating more area to corn than initially planned. Brazil's soybean production forecast remained unchanged at 186 MMT, while Argentina's stood at 50 MMT. Planting has advanced rapidly in Mato Grosso, reaching 96% by November 6, more than ten percentage points ahead of last year. Paraná, however, was running behind its previous-year pace, with 79% of soybeans planted as of November 9, compared with 86% a year earlier. Crop conditions also warrant attention: 84% of Paraná's soybeans were rated good, below 91% last year. The favorable start in some regions does not eliminate weather risks, particularly as November and December rainfall becomes increasingly important for crop development.

Wheat: Southern Hemisphere Supplies Improve as Black Sea Constraints Persist

USDA raised projected global wheat production by approximately 5.1 MMT to 827.5 MMT, supported by improved Southern Hemisphere prospects. Argentina's production forecast increased by 1.5 MMT to 23 MMT, while Australia's rose by the same amount to 32.5 MMT. These larger crops strengthen export availability as harvesting advances. Trade revisions, however, reflect contrasting regional conditions. USDA lowered wheat export forecasts for Russia and Ukraine by 1 MMT each, citing limited maritime access through the Black Sea, while raising Argentina's exports by 1 MMT on a larger production forecast. Stronger Southern Hemisphere competition continues to challenge U.S. wheat exports, although Black Sea logistical disruptions could alter trade flows and destination choices.

Washington: Farm Policy Enters a New Political Phase

The November midterm elections have altered the political outlook for agricultural policy, with Democratic gains in agricultural states raising questions about the direction of the next Farm Bill and congressional negotiations. The immediate challenge remains whether lawmakers can reach a bipartisan agreement during the lame-duck session or whether another extension will be necessary. SNAP cost-sharing provisions remain a major point of disagreement, while year-round E15 sales continue to attract interest from corn producers and the ethanol industry. Expanded E15 access could support longer-term domestic corn demand, although its eventual impact would depend on legislative action, implementation, and fuel market adoption. Agricultural groups are also watching federal spending negotiations ahead of the December 11 continuing-resolution deadline. For producers facing narrow margins, uncertainty over farm programs, trade policy and input costs adds to the difficulty of planning for the 2027 season.

USDA's Long-Term 2036 Outlook: Useful Direction, Limited Policy Visibility

USDA's early-release agricultural projections through 2036 provide a longer-term reference for U.S. crop and livestock markets. These baseline projections are useful for examining expected trends in acreage, yields, consumption, and trade under existing policy assumptions, but they should not be interpreted as predictions of future policy decisions. One limitation becomes more apparent toward the latter part of the projection period. Several demand-related series show stronger adjustments in the early years before their growth slows or levels off. This is partly a consequence of baseline modeling that assumes currently enacted policies remain in place, rather than anticipating future biofuel mandates, trade agreements, or other regulatory changes. The projections therefore offer more meaningful insight into the direction of agricultural markets over the next several years than into precise outcomes a decade ahead. For markets increasingly influenced by renewable fuel policy, international trade relationships and regulatory changes, alternative scenarios are essential to evaluating longer-term demand.

What We Are Watching Next

Following the November WASDE, attention shifts from production revisions to the pace at which available supplies are absorbed by international markets. U.S. Export Sales reports will be a central indicator, particularly for soybeans, soybean meal, and corn. For soybeans, Chinese purchasing activity and sales to other destinations will help determine whether demand can support USDA's reduced ending-stock forecast. Soybean meal sales will provide additional evidence of international demand for U.S. crushing products, while corn sales and shipments will indicate whether exporters can capitalize on opportunities in markets such as Mexico. South American crop progress will be equally important. Soybean planting and early crop development in Brazil and Argentina, rainfall distribution and the timing of Brazil's safrinha corn planting will shape production expectations for 2026/27. With USDA projecting another large South American soybean harvest, changes in weather or planting schedules could influence expectations for export competition in early 2027. For now, November's WASDE has tightened U.S. corn and soybean balances, but the durability of any price support will depend on export performance and the development of South America's next harvest.
