Corn prices ease on US weather relief and weaker oil, but EU heat stress and lower MARS yields keep European maize markets supported.
Prices
Weaker crude oil prices and improved US weather weighed on CBOT corn on Monday as traders locked in profits after the recent rally. In Europe, maize losses on Euronext were markedly smaller, with local fundamentals in Western and Central Europe remaining supportive due to deteriorating crop prospects.
Northwest German cash markets reacted swiftly: following a EUR 10/t cut on Friday, feed mills raised July/August bids by EUR 12/t on Monday to about EUR 268/t, more than offsetting the prior reduction. Current spot offers confirm this firm tone, with German feed-grade corn around EUR 256–266/t ex works and French yellow corn near EUR 250/t FOB, while Ukrainian feed corn trades at a significant discount around EUR 179–190/t CPT/FOB.
Supply & Demand
US supply sentiment has improved marginally in the very short term. After a hot weekend, forecasts now call for a temperature drop and rainfall across large parts of the Corn Belt, reducing immediate pollination stress and prompting hedge and fund selling. This weather shift comes even as the USDA’s latest Crop Progress report shows only 63% of US corn rated good or excellent, a 4‑point decline from the previous week and worse than analysts’ expectations of a 2‑point drop, confirming that recent heat has already taken a toll.
On the export side, the USDA reported US corn shipments at 1.488 million tonnes in the week to 23 July, down 7.7% from the prior week and 2.9% below the same week a year earlier. Mexico, Japan and Colombia led demand. Despite the weekly setback, cumulative 2025/26 exports have reached 75.3 million tonnes, standing 25% above the year-ago pace and underlining that the US remains highly competitive in world markets.
In Europe, the balance is clearly tighter. The MARS service has cut its average EU grain maize yield estimate for 2026 to 6.93 t/ha (from 7.38 t/ha in June), citing exceptional heat and limited rainfall in Western and Central Europe that depleted soil moisture and disrupted flowering. The outlook for August remains predominantly hot and dry in these regions, increasing the risk of further yield losses and sustaining strong import and feed demand for maize into 2026/27.
Fundamentals & Weather
The fundamental picture is increasingly weather‑driven on both sides of the Atlantic. In the US, the recent downgrade in condition ratings to 63% good/excellent comes at a critical stage for yield formation, indicating that a portion of the crop has already suffered irreversible stress. However, near-term forecasts call for cooler temperatures and scattered rain across much of the Corn Belt, which should stabilize conditions where damage is not yet permanent and has eased immediate production fears.
Europe faces the opposite trajectory. MARS highlights that persistent hot and dry weather has limited biomass accumulation and impaired maize flowering, especially in Western and Central Europe. With August also expected to be hotter and drier than normal, the probability of further cuts to maize yield projections is high, and regional observers already report stress in key producing areas such as France and parts of Germany. This contrast—stabilizing US prospects versus deteriorating EU yields—is central to current price dynamics.
4–6 Week Outlook & Trading View
Over the next month, the market will track US weather during the late pollination and early grain-fill window alongside evolving EU yield estimates. If cooler, wetter conditions persist in the Corn Belt, US production risks could continue to moderate, putting a cap on CBOT rallies despite the recent deterioration in ratings. Conversely, any renewed heat dome or rainfall shortfall during August would quickly revive weather premiums.
In Europe, the baseline remains structurally supportive. With MARS already pointing to materially lower maize yields and forecasts skewed towards hot and dry conditions, further downgrades look more likely than upward revisions. That should keep EU and German cash markets underpinned, especially given firm feed demand and the need to compensate for lost domestic volumes with imports, including competitively priced Ukrainian corn.
Trading outlook (next 2–4 weeks)
- Feed buyers in Western/Central Europe: Use any weather‑driven dips to extend coverage into Q4, as lower MARS yields and hot August risks argue for continued support in local basis and cash prices.
- Producers in the EU: Consider layering in additional sales only on strong rallies; weather and yield uncertainty still offer upside risk, particularly if August conditions disappoint and export competition tightens.
- Importers in MENA and Asia: Maintain a diversified origin strategy. US corn remains well supplied and competitively priced, but EU shortfalls and logistics from the Black Sea could tighten global spreads later in the season.
3-day regional price indication / direction
- CBOT corn (converted to EUR/t): Slightly softer to sideways as cooler, wetter US forecasts and weaker oil encourage further profit‑taking.
- Euronext maize (EUR/t): Sideways to mildly firmer, with lower MARS yields and persistent heat in Western/Central Europe offsetting US weakness.
- Northwest Germany cash (EUR/t): Around 260–270 EUR/t, biased slightly higher as feed mills rebuild coverage amid tightening local crop prospects.
