Corn Market Caught Between Weak Old-Crop Demand and Weather-Driven Rally

Old-crop corn prices remain under pressure from weak Ukrainian export demand, cheaper competing feed grains and heavy South American competition, but weather concerns in Europe and firmer futures are putting a floor under values and supporting new-crop pricing. The global corn market has split into two tracks. On the one hand, Ukrainian spot export values are softening as Turkish and EU demand ease and South American origins undercut Black Sea offers. On the other hand, drought-related risks in Western Europe and solid U.S. and Brazilian crop prospects are driving a weather‑sensitive rally on Euronext and CBOT, with European buyers already locking in sizeable volumes of Ukrainian new‑crop. Volatility is likely to stay elevated as the Northern Hemisphere enters a critical yield‑formation window.

Prices

Export purchase prices for old-crop Ukrainian corn delivered Black Sea ports have fallen by roughly UAH 100–200 per tonne over the past week, to about USD 211–213/t. Converted at an indicative rate of 1 USD ≈ 0.92 EUR, this implies around EUR 194–196/t at port. New-crop Ukrainian corn for October–December delivery is quoted slightly lower in dollar terms at USD 210–215/t, but the forward curve is supported by strong European demand and weather risks.

Physical offers confirm the softer Black Sea basis: recent Ukrainian FOB corn out of Odesa is indicated near EUR 185/t, with CPT Odesa feed-grade offers broadly stable around EUR 185/t as well, while French FOB yellow corn around Paris has eased from roughly EUR 260/t in late June to about EUR 250/t. On the futures side, November corn on Euronext Paris recently corrected from a two‑year high of EUR 239.25/t to about EUR 232.25/t, still almost 13% above levels one month earlier, while CBOT December corn added just over 3% on the week, capped by good U.S. crop prospects.

Supply & Demand

Export demand for Ukrainian corn has clearly weakened as traders complete earlier contracts and show little appetite to extend coverage at prevailing spot prices. Several importers, notably Turkey, are shifting to their own large barley and wheat harvests and an expected favourable domestic corn crop, reducing immediate import needs. This has thinned buying interest at Black Sea ports and intensified competition among Ukrainian exporters.

In the EU, 2025/26 corn imports are down 7% to 18.47 million tonnes, with Ukraine’s share falling from 11.0 to 8.5 million tonnes as buyers diversify into U.S. and Brazilian origins. Ukrainian corn now accounts for about 46% of EU imports, U.S. shipments for nearly 32%, and Brazilian volumes have roughly doubled to 3.0 million tonnes. At the same time, robust second‑crop harvest progress in Brazil and large Argentine export availability are adding substantial competition into July–August loading windows, especially into Europe.

Fundamentals & Competing Grains

Lower prices for competing feed grains are reinforcing pressure on corn. Export values for feed barley delivered Black Sea are down to about USD 185–190/t (≈EUR 170–175/t), and feed wheat is quoted around USD 195–198/t (≈EUR 180–183/t). With corn directly substitutable in many rations, these cheaper alternatives reduce livestock buyers’ willingness to pay up for corn and strengthen the hand of importers in price negotiations.

Despite the weaker old-crop tone, forward sales of Ukrainian new-crop corn to European buyers are robust at USD 210–215/t (≈EUR 193–198/t) for October–December shipment. This forward demand anchors expectations for the coming season and helps limit further downside on nearby prices, as farmers compare spot bids with more attractive forward opportunities. Globally, ample Brazilian and Argentine supply in the third quarter, together with generally favourable U.S. production prospects, point to comfortable overall availability, even as Europe looks increasingly tight.

Weather & Crop Conditions

Weather has become the key driver of price volatility as Northern Hemisphere corn enters its critical reproductive phase. While growing conditions in Ukraine and the U.S. Corn Belt remain broadly favourable, Western Europe – and France in particular – has suffered from prolonged high temperatures. The share of French corn rated good or excellent plunged from 84% three weeks ago to 58% by late June, down sharply from 76% a year earlier, the weakest reading in 13 years.

These deteriorating French crop conditions have underpinned the rally in Paris futures and increased concerns about EU production. In contrast, the U.S. crop is holding up well: USDA data show 67% of U.S. corn in good or excellent condition in the week ending 5 July, unchanged on the week but below last year’s 74%, with forecasts calling for 20–60 mm of rain and temperatures around 30–33°C across much of the Corn Belt. In Brazil, AgRural estimates second‑crop harvest in the Center-South at 30% of area, slightly ahead of last year, ensuring a steady stream of exportable supply.

Outlook & Trading Recommendations

Over the coming weeks, corn pricing will hinge on European weather, U.S. yield outcomes and the pace of South American exports. If heat persists across Western Europe without sufficient rainfall, further yield losses could tighten EU balance sheets and keep Euronext and physical EU prices elevated, supporting demand for Ukrainian new-crop. Conversely, a turn to milder, wetter conditions could stabilise European production expectations and deflate some of the current risk premium.

• Producers in Ukraine: Consider scaling into forward sales of 2026 crop at current USD 210–215/t (≈EUR 193–198/t) for Oct–Dec delivery, particularly for volumes with secure logistics, while retaining some weather‑linked upside via unsold tonnage or optionality.
• European feed buyers: Use current breaks in Euronext futures from recent highs to extend coverage into Q4 2026, balancing Ukrainian and South American origins, but avoid over‑coverage given ongoing U.S. and Brazilian crop strength.
• Traders: Old-crop Black Sea basis remains vulnerable to further softness as Brazilian and Argentine offers (around USD 200–220/t FOB, or roughly EUR 184–202/t) stay aggressive; focus on origin spreads and EU/U.S. futures arbitrage rather than outright flat-price exposure.

In the next three trading days, physical Ukrainian export prices are likely to remain under mild downward to sideways pressure, while Paris futures should stay volatile but broadly supported as markets track European weather updates. CBOT corn is expected to consolidate recent gains, with any shift in U.S. weather forecasts quickly reflected in intraday moves.
