US Corn Stocks Jump, Pressuring Futures While Global Supply Stays Ample

US corn prices are under renewed pressure after the latest USDA grain stocks report showed a much more comfortable supply situation than a year ago. Futures on the CBOT retreated to multi‑week lows, while Euronext corn held broadly steady and physical prices in Europe and the Black Sea remain soft amid ample global availability. After several months of weather‑driven volatility, the market is now digesting a combination of sharply higher US old‑crop stocks, another near‑record US harvest, still‑strong Brazilian export flows and an improving supply outlook in China. Together, these factors reinforce a fundamentally bearish tone, even as strong disappearance and regional logistics occasionally inject short‑term noise into prices.

Prices

US corn futures fell sharply after the USDA’s quarterly report. Old‑crop US corn stocks as of September 1, 2026 were reported at 2.10 billion bushels, up 35% year‑on‑year, triggering a notable sell‑off in Chicago and pushing the December 2026 contract down to a six‑week low before stabilizing around 499 US‑cents/bu in early trade on October 1.

On Euronext, the nearby November 2026 corn contract last traded at 264.25 EUR/t, with the forward curve only slightly lower into 2027–28, underscoring a broadly stable but well‑supplied European balance sheet. Physical offers mirror this picture: German feed corn EXW Drentwede is currently indicated at 0.29 EUR/kg, while Ukrainian feed corn CPT Odesa stands at 0.154 EUR/kg and FOB Odesa at 0.156 EUR/kg, both close to recent lows. Indian organic corn starch FOB New Delhi trades markedly higher at 1.32 EUR/kg, reflecting its niche, value‑added segment.

Supply & Demand

US fundamentals have shifted decisively more comfortable. As of September 1, 2026, total US corn inventories were 2.10 billion bushels, versus 1.55 billion bushels a year earlier, with off‑farm stocks up 44% to 1.31 billion bushels and on‑farm stocks up 22% to 787 million bushels. Despite this, disappearance from June to August reached 3.20 billion bushels, slightly above last year’s 3.09 billion, confirming robust demand but not enough to prevent a significant stock rebuild.

The 2025 US corn crop has been revised down by only 57 million bushels to 16.964 billion bushels, less than 1%, and remains a record, based on an unchanged yield forecast of 186.5 bu/acre. This combination of record production and much higher carry‑in ensures a very comfortable starting point for the new marketing year.

Brazil, meanwhile, continues to ship large volumes, though recent data point to slightly softer flows than previously expected. September corn exports are now estimated around 5.4 million tonnes, down modestly from earlier projections, which mildly tempers immediate global export pressure but leaves South America firmly positioned as a key supplier. At the same time, China’s agriculture ministry expects a strong 2026 grain harvest with expanded acreage in high‑yielding crops such as corn, reinforcing prospects for higher domestic feed grain availability and potentially reducing incremental import needs over the medium term.

Fundamentals & Regional Prices

Fundamentals across the main hubs are clearly aligned towards abundant supply:

• United States: High beginning stocks and a record 2025 crop underpin a burdensome balance sheet, even with strong feed and industrial use. The surprise in the September stocks figure was the main bearish catalyst for futures.
• Brazil: Export volumes in September are strong but slightly below earlier expectations, offering only a minor reprieve to global prices. Overall south‑American availability remains ample.
• China: Expanded corn area and favorable summer and early‑autumn conditions support expectations for a bumper 2026 harvest, improving domestic feedgrain security.

Weather Snapshot

Early‑October forecasts for the US Corn Belt point to mostly seasonable to slightly above‑normal temperatures with limited heavy rainfall risk, a pattern generally favorable for late harvest progress and grain drying. In China’s North‑East and North China Plain, September conditions were reported as broadly favorable, with sufficient warmth and manageable precipitation aiding grain fill and ripening, supporting expectations for an above‑average autumn harvest.

Outlook & Trading Implications

• Flat to slightly lower bias: With US stocks up 35% year‑on‑year and another record crop confirmed, rallies on CBOT are likely to meet selling interest unless weather or logistics issues emerge in key exporting regions.
• Hedging for producers: US and European growers should consider layering in additional price hedges on remaining old‑crop and early new‑crop sales on bounces, given the fundamentally heavy global balance.
• Buying opportunities for users: Feed compounders and industrial buyers in the EU and Black Sea region may use current weak basis and futures levels to extend coverage into early 2027, particularly from Ukraine and Germany where cash offers remain competitive.

3‑day directional view

• CBOT corn (Dec 26): Slight downside risk or range‑bound trade as markets consolidate the bearish stocks data.
• Euronext corn (Nov 26): Expected broadly sideways, tracking Chicago but cushioned by local demand and currency moves.
• Physical EU/Black Sea feed corn: Stable to mildly softer as exporters remain aggressive and logistics conditions are seasonally favorable.
