Corn jumps in Europe as Ukraine risks flare, while CBOT softens on better US crop outlook

Corn prices are diverging between Europe and the US: Euronext maize has broken back above EUR 250/t on renewed Ukraine and EU crop concerns, while CBOT futures are slightly softer as improved Midwest rainfall and a larger private US crop estimate cap the upside. In Europe, strong cash demand and fears over Ukrainian export disruptions are pushing nearby values higher, particularly in northwest Germany where feed compounders are paying the highest prices since mid‑2023. At the same time, forward Euronext contracts remain inverted against cheaper 2027–28 months, signalling tightness in the short term but more comfortable longer‑term supply expectations. In contrast, US futures are under mild pressure as better weather and a larger StoneX harvest forecast temper bullish enthusiasm, despite steady export interest and resilient ethanol demand. Overall, the market is caught between Black Sea risk premia and increasingly comfortable US and global balance sheets.

Prices

European corn markets are firm. The November 2026 Euronext maize future last traded around EUR 250.25/t, closing for the first time in a week back above the key EUR 250/t mark, with nearby August 2026 at roughly EUR 250/t as well. Spot physical prices in northwest Germany are even stronger at about EUR 276/t for August delivery, the highest since July 2023, underlining tight regional supply. The forward curve shows a clear inversion: August 2026–August 2027 contracts cluster around EUR 248–251/t, while November 2027 and the 2028 strip trade substantially lower near EUR 225/t. This structure reflects current supply stress in Western Europe and Ukraine but expectations of relief in later seasons. On CBOT, corn is modestly firmer intraday but still trading below recent highs: September 2026 is around 438 USc/bu and December 2026 near 461 USc/bu, up only 0.3–0.4% on the day. In China, Dalian corn is broadly steady with front‑month prices just above 2,240 CNY/t, indicating a relatively balanced domestic situation. In the physical export market, recent offers imply roughly EUR 170–180/t FCA/FOB for Ukrainian feed corn (Odesa) and around EUR 260/t FOB for French yellow corn, while German EXW feed corn trades in the EUR 255–275/t range depending on timing and quality. These levels are broadly consistent with the Euronext and CBOT futures structure when accounting for logistics and basis.

Supply & Demand

European fundamentals are turning more supportive. Poor crop prospects in Western Europe, particularly in France and parts of Germany, are being priced more aggressively again, helping to lift Paris futures. Domestic feed demand remains robust, as shown by elevated German cash prices, which are pulling additional imports from Ukraine and France into northwest Europe. Ukraine’s export outlook has deteriorated sharply in recent days. Russian attacks on Black Sea ports and infrastructure have led to the temporary suspension of merchant ship arrivals at key Ukrainian ports and forced exporters to increasingly rely on rail, road and smaller alternative routes. These alternatives, however, are expected to cover only around half of pre‑war export volumes at best and may not reach that capacity until the end of August, implying a significant near‑term constraint on Ukrainian corn flows to the EU and global markets. In the US, the balance sheet is moving in the opposite direction. A fresh private forecast from StoneX pegs the 2026/27 US corn harvest at about 16.16 billion bushels, above the USDA’s latest projection of 16.0 billion bushels, reinforcing expectations of comfortable supplies. Rainfall expected across key parts of the Midwest is likely to stabilise or improve yield prospects, limiting weather‑driven risk premia on CBOT. On the demand side, export activity remains steady. USDA has reported new sales of 120,000 t of corn to Mexico, split between the current and next marketing years. For the latest weekly export report, analysts anticipate 200,000–600,000 t for old‑crop and 700,000–1.2 million t for new‑crop shipments, which would be broadly in line with seasonal norms and consistent with maintaining competitive US export participation.

Fundamentals & Ethanol

The US ethanol complex continues to underpin domestic corn demand but with signs of slightly softer grind. In the week to 31 July, average US ethanol output was 1.107 million barrels per day, down 26,000 bpd week‑on‑week, while stocks rose by about 202,000 barrels to 24.524 million barrels. Ethanol exports, however, jumped to around 200,000 bpd, up 63,000 bpd, partially offsetting weaker domestic draws. Refinery corn intake for ethanol eased marginally to roughly 936,000 bpd equivalent, hinting at a small downtick in corn usage but not a structural shift. Overall, the ethanol data signal a still‑solid but no longer accelerating demand pillar, aligning with the broader picture of a well‑supplied US corn market with only moderate support from biofuel. In Europe, industrial demand (starch and bioethanol) is steady, but the current rally is being driven more by feed buyers and supply‑side risks than by processing margins. Starch‑grade corn prices remain significantly higher than feed values, particularly for organic specialty origins, reflecting tightness in niche segments rather than broader scarcity.

Weather & Risk Outlook

Near‑term weather in the US Midwest is turning less threatening. Forecasts for the coming days point to scattered showers and moderate temperatures across large parts of the Corn Belt, which should support pollination and grain fill for much of the crop. This reduces the probability of a major yield shock and supports the more bearish StoneX production scenario. By contrast, Europe remains vulnerable to weather and logistics risk. Parts of Western Europe have seen yield‑reducing conditions earlier in the season, and there is limited scope for a late recovery in corn potential. At the same time, the escalation of Russian attacks on Ukrainian deep‑water ports and export terminals has significantly increased the geopolitical risk premium. Traders expect alternative export routes—rail to EU, Danube and smaller Black Sea ports—to reach only around half of former deep‑sea capacity, and not before late August, keeping nearby European prices sensitive to any further disruption.

Trading Outlook (1–3 weeks)

• EU consumers (feed, livestock): Consider extending cover on dips for Q4 2026–Q1 2027, as the strong inversion and Ukrainian export risks argue for persistent tightness in nearby European basis, even if global futures soften.
• Producers in Western Europe: The move of Euronext November back above EUR 250/t offers attractive hedging opportunities. Incremental sales or option‑based strategies around this level can lock in historically strong margins while retaining some upside to further Black Sea or weather‑driven spikes.
• Importers in MENA/Asia: Monitor the spread between CBOT and Black Sea/EU offers. If Midwest weather remains benign and the US crop tracks closer to the higher StoneX estimate, weakness in CBOT could present chances to shift a portion of demand toward US origin at competitive EUR‑equivalent prices.
• Speculative traders: The fundamental set‑up favours a relative value stance: long Euronext vs. short CBOT on continued European/Ukrainian tightness versus a comfortable US balance, but beware of position crowding and headline‑driven volatility from the Black Sea.

3‑Day Directional Outlook

• Euronext maize (Aug & Nov 2026): Mildly bullish bias. Ongoing concerns over Ukrainian exports and weak Western European yields should keep prices supported above EUR 245–250/t, with upside spikes possible on any fresh port attacks or logistics headlines.
• CBOT corn (Dec 2026): Slightly bearish to sideways. Improved Midwest weather and a heavy US crop outlook argue for consolidation or a modest pullback unless export sales or new weather threats surprise to the upside.
• Black Sea physical (Ukraine): Firm basis but volatile. Port disruptions and capacity limits on alternative routes are likely to sustain elevated FOB/CPT premiums versus CBOT over the next few days, with risk skewed to further tightening if attacks intensify or insurance costs rise.
