Corn Market Balances Weather Risks, Weak Exports and Firmer Energy

Hot and dry forecasts in the US Corn Belt and persistent heat in northern France are emerging as key yield risks, while Germany enjoys a brief spell of beneficial rains before the next heatwave. At the same time, US corn export sales disappointed versus expectations, tempering weather-driven price upside. European and US futures are firmer but not in a full weather rally, leaving the market in a fragile balance between weather risk, soft demand and rising energy costs. Corn is trading in a relatively tight range, with Euronext new-crop around EUR 255–258/t and CBOT December 2026 near EUR 175–180/t equivalent, as traders weigh deteriorating crop prospects in parts of the US and France against lacklustre export demand. Germany should benefit from widespread rain in the coming week, stabilising local yield prospects. However, forecasts point to renewed heat in Central Europe and sustained above-normal temperatures and dryness for much of the US Corn Belt, keeping a clear weather premium in global prices.

Prices

Euronext corn futures closed on 23 July with nearby and new-crop contracts clustered in a narrow band: August 2026 at EUR 254.75/t, November 2026 at EUR 257.50/t and March 2027 at EUR 257.25/t. Deferred contracts into 2028 trade only slightly lower, signalling a relatively flat forward curve and a market still unsure about long‑term supply.

On CBOT, corn futures are modestly higher, with September 2026 at 466 USc/bu and December 2026 at 490 USc/bu in early 24 July trading, up around 0.4–0.5% on the day. Converted at roughly 1.10 USD/EUR, this places December 2026 CBOT near EUR 174–178/t, still at a discount to Euronext and underlining a continued freight and risk premium in European values.

Physical offers mirror the futures firmness but with only moderate volatility. German feed corn EXW Drentwede is indicated around EUR 0.266/kg (EUR 266/t) on 24 July, slightly above mid‑July levels near EUR 250–255/t. Ukrainian feed corn ex‑Odesa has softened from early July, with recent FCA/CPT values near EUR 180–190/t, maintaining Ukraine’s role as a competitive origin for EU and Mediterranean buyers.

Supply & Demand

Weather is the dominant supply driver. The US Corn Belt faces several days of hot and dry conditions, raising concern about pollination and grain fill at a critical stage. While seasonal outlooks still point to a broadly moderate summer, short‑term heat and moisture stress in key states could trim yield potential if high temperatures persist into early August.

In Europe, the picture is mixed. Germany is forecast to receive widespread rainfall over the next seven days with otherwise typical summer conditions, supporting soil moisture and stabilising yield expectations. In contrast, the northern half of France is expected to remain largely dry, with above‑average temperatures projected again for the coming two weeks, heightening the risk of yield losses in some of the EU’s most productive corn areas.

Beyond weather, demand signals are soft. The latest USDA weekly export report for the week ending 16 July showed net US corn sales of 332,700 t for 2025/26 and 701,500 t for 2026/27, both at the lower end or below market expectations of 400,000–800,000 t for each season. External commentary confirms that old‑crop corn sales reached roughly 13.1 million bushels, with new‑crop at about 27.6 million bushels in that week, underscoring a lack of urgency from key importers.

Fundamentals & Macro Drivers

Fundamentally, the corn market is caught between weather‑driven supply risk and a hesitant demand side. The flat Euronext forward curve around EUR 255–258/t from 2026 into 2027 suggests that the market does not yet price in a major global deficit, but it keeps a notable weather premium as long as US and French conditions stay uncertain. Ample old‑crop stocks and weak export sales are providing a buffer against a sharper weather rally.

Macro factors are turning more supportive. Crude oil prices moved back above 100 USD/bbl for the first time in two months amid heightened geopolitical tensions, including reported attacks on Saudi oil tankers in the Red Sea and near‑standstill traffic through the Strait of Hormuz. Higher energy prices tend to underpin corn via ethanol margins and broader commodity investor flows, adding a bullish layer on top of existing weather concerns.

Weather Outlook

For the next 7–14 days, model guidance points to continued hot, mostly dry conditions in large parts of the US Corn Belt, though isolated storms may offer local relief. The key risk window spans late July into early August, when sustained high temperatures and limited rainfall could materially impact yield outcomes.

Germany is set for almost nationwide rainfall in the coming week, followed by a likely new heatwave. This sequence should temporarily improve soil moisture but could stress crops again later if follow‑up rains are limited. Northern France, by contrast, is forecast to see largely dry weather with recurring heat through the next two weeks, reinforcing downside yield risks and supporting European basis levels.

Trading Outlook (1–3 weeks)

• Producers (EU): Use current strength above EUR 255/t on Euronext Nov 2026 to incrementally hedge 10–20% of unpriced new‑crop, especially in regions expecting better weather (e.g. Germany). Retain some upside exposure given US and French weather risks.
• Importers/feed buyers: Stagger coverage, taking advantage of the still‑moderate CBOT levels and competitive Ukrainian offers around EUR 180–190/t. Avoid over‑coverage ahead of the crucial US pollination period when weather volatility could create price setbacks.
• Traders/speculators: The risk‑reward currently favours a cautiously bullish bias, with tight stops, as hot and dry US and French forecasts and recovering energy markets can support further gains. However, weak export sales limit upside unless weather damage becomes more evident.

3‑Day Price Indication (Directional)

• Euronext corn (front months): Slightly firmer bias in EUR, supported by US heat and French dryness; intraday volatility likely to increase with forecast updates.
• CBOT corn: Mild upward tendency in EUR terms, tracking US weather headlines and stronger energy, but capped by subdued export demand.
• EU physical (Germany/France, feed corn): Stable to slightly higher, as farmers show limited selling interest ahead of the next heatwave and buyers secure nearby needs.
