Corn edges higher as USDA trims stocks while Argentina lifts record crop outlook

Corn prices are edging higher but remain range-bound, as tighter US balance sheets and solid demand are offset by strong South American supply prospects and calmer Black Sea risk premiums. Corn futures and physical prices are consolidating after recent gains, with modest weakness on CBoT but relatively firm levels on Euronext and in European cash markets. The latest WASDE cut to US ending stocks and stronger export outlook provide a supportive fundamental backdrop, while higher Argentine crop estimates and steady Chinese values cap the upside. Weather and upcoming US export data will guide the next move, with a sideways to slightly firmer bias near term.

Prices

Euronext corn (Nov 2026) is unchanged at about 248 EUR/t, with the 2027 strip around 243–245 EUR/t and a notable discount further out, as Nov 2027 trades near 220 EUR/t. Nearby contracts show low intraday volatility and thin turnover, indicating a pause after the recent rally.

On CBoT, front-month Sep 2026 corn is softer at roughly 454 USc/bu (about 210–215 EUR/t equivalent), down around 0.7% on the day, with a similar curve shape into 2027–2028. Chinese DCE corn is also slightly lower, reflecting a mild global easing tone but without aggressive selling pressure.

Spot physical indications broadly confirm this consolidation: German feed corn in Drentwede is around 274 EUR/t EXW (up from 256–268 EUR/t in late July), French FOB Paris yellow corn near 250 EUR/t, and Ukrainian offers out of Odesa around 170–180 EUR/t on an FOB/CPT basis. The cash market thus trades at a modest premium to international futures benchmarks, highlighting ongoing regional demand and logistics costs.

Supply & Demand

The global balance has turned slightly tighter on the US side. The latest USDA update cut US 2026/27 ending stocks from 45.5 to 42.0 million tonnes and raised US export projections by 1.9 million tonnes to 83.2 million tonnes, underlining robust international demand for US corn. The new stock figure is below earlier market expectations, adding a mild bullish nuance to the outlook.

At the same time, South America is acting as a strong counterweight. The Rosario Board of Trade increased its estimate for Argentina’s 2025/26 corn crop from 68 to a record 70.5 million tonnes, citing a larger-than-expected planted area, with harvest already 75% complete. For 2026/27, Rosario projects 66 million tonnes, well above USDA’s current 55 million tonne forecast, suggesting downside risk to global prices if these larger volumes materialise as expected.

Black Sea developments continue to influence sentiment but, for now, are providing only moderate support. Rising wheat prices and ongoing geopolitical uncertainties in the region initially helped corn, yet ample export availability from Ukraine and other origins is limiting any sustained risk premium. Overall, the market is balancing somewhat tighter US fundamentals against comfortable exportable supplies from South America and the Black Sea.

Fundamentals & Demand

On the demand side, US ethanol continues to absorb substantial corn volumes. Weekly EIA data for the week to 7 August show ethanol output at 1.117 million barrels per day, up 10,000 barrels per day from the previous week, while stocks rose by 274,000 barrels to 24.798 million barrels. This combination points to solid but not overheating domestic industrial demand.

Export flows remain a key swing factor. For the marketing year ending 31 August 2026, market participants expect Thursday’s USDA export report to show either modest net cancellations of up to 100,000 tonnes or net sales of up to 400,000 tonnes for old crop. New-crop (2026/27) sales are forecast in a healthier 800,000 to 1.4 million tonne range, consistent with the USDA’s higher export projection and indicating continued strong importer interest at current price levels.

Regionally, European feed demand has so far absorbed the upward drift in prices, though margins in livestock sectors are becoming tighter. In Ukraine, competitive FCA and CPT offers from Odesa show that exporters are still pricing aggressively to maintain market share, which, together with firm Argentine supply, acts as a ceiling on any sharp rally in European and US prices.

Weather & Crop Outlook

Weather remains a critical medium-term risk, especially in the US and Argentina. With the Argentine 2025/26 crop largely harvested and 2026/27 planting scheduled to start in September, attention will increasingly shift to rainfall patterns and temperature during sowing and early vegetative stages. Any deviation from current favourable expectations could quickly challenge the very high production forecasts from Rosario.

In the Northern Hemisphere, late-season weather in the US Corn Belt and parts of Europe will still influence yield potential, but the window for major production shocks is gradually closing. Absent a significant weather surprise, the market is likely to treat current yield assumptions as broadly stable, with fundamental focus turning more toward demand, exports and logistics.

Trading Outlook

• Short-term bias: Sideways to slightly firmer. Tighter US stocks and strong export demand argue against a deep correction, but heavy South American and Black Sea supplies limit upside.
• Producers (EU/US): Consider layering in additional forward sales on rallies for 2026/27, especially where local cash premiums are elevated versus futures, while keeping some unpriced volume in case of weather or logistical disruptions.
• Consumers (feed, ethanol): Use current consolidation to secure a portion of Q4 2026–Q2 2027 coverage. Focus on origin flexibility, as Ukrainian and Argentine offers remain competitive versus domestic supplies.
• Speculators: Range-trading strategies around current futures levels remain appropriate, with a slight preference for buying breaks given the lower US ending stock profile.
