Market Report 28th July 2026

Headlines
Firefighters in France and Spain are racing to bring huge wildfires under control before another heatwave this week that will complicate efforts to tame the flames.

A fourth heatwave of the year is now under way for parts of the UK, with temperatures expected to climb into the mid-30s Celsius later this week.

Ukraine has dismissed Iranian threats of retaliation, following Kyiv's targeting of an Iranian cargo vessel in the Caspian Sea on Saturday.

The price of oil has fallen sharply on hopes that a pause in attacks between the US and Iran could help to de-escalate the conflict.

Daily Market Update

Wheat
Another volatile session with a £7 intraday range on London November 2026 before closing virtually unchanged at £199.50, down just 0.25p. Paris/Matif December eased 1.50 euros to €234.75. The market wanted to fall further on peace optimism and oil weakness but found buyers every time it approached support — a sign that the physical supply reality is preventing a sustained correction even when geopolitical sentiment softens. OSR suffered more significantly, down approximately 15 euros in sympathy with a sharp crude oil correction.

The EU MARS bulletin published yesterday delivered the most comprehensive official confirmation yet of European crop damage — yield downgrades across every major crop simultaneously. Soft wheat revised to 5.88 t/ha from 6.00 t/ha, barley to 5.02 t/ha from 5.09 t/ha, corn to 6.93 t/ha from 7.38 t/ha — a 6.1% corn yield reduction in a single monthly update — rapeseed to 3.14 t/ha from 3.18 t/ha, and sunflower to 2.62 t/ha from 2.75 t/ha. Every single crop revised lower simultaneously is an institutional confirmation of what field reports have been saying for weeks.

Ukraine's export capacity is estimated down approximately one third and Russia's down approximately one quarter from conflict damage, with repair timelines uncertain. The UN Security Council raised Black Sea grain exports yesterday without concrete progress. Today's Trump-Zelensky meeting is the market's most anticipated near-term event — any concrete shipping framework would move prices sharply, though analysts remain sceptical of a meaningful outcome.

A significant longer-term question is emerging — with farmers needing to move grain through disrupted and congested export routes, combined with fertiliser supply problems, will autumn wheat planting enthusiasm be significantly reduced? The 2027 supply story is being written now in farm office decisions across Ukraine, Russia and Eastern Europe.

Oil & Rapeseed
Brent has fallen to $85/barrel — its lowest since July 16th — on the US-Iran pause in strikes over the weekend. The pause is real but oil markets are pricing a temporary ceasefire rather than a resolution, which is probably the correct read. Rapeseed bore the brunt of the oilseed correction, falling 14.25 euros on the November 2026 contract as the entire vegetable oil complex corrected sharply in the wake of crude. The structural supply story for oilseeds has not changed — the correction is energy-driven not fundamental.

Russia
Russian wheat production cut to 90 million tonnes — down 1.8 million tonnes from previous estimates but still above the USDA's 88.5 million tonne forecast. Exports forecast at 44.5 million tonnes, 3.7% below last year. The gap between private Russian estimates and the USDA number suggests further downward revision risk in official forecasts.

US Markets
Mixed session as rain forecasts and easing temperatures provided some relief to corn and soybean concerns. However crop ratings deteriorated sharply — corn fell 3 points to 63% good/excellent against 73% last year, soybeans also down 3 points. The American weather model predicts 10mm of Corn Belt rainfall in seven days while the European model suggests over 20mm — a significant divergence at a time when crops are deteriorating rapidly. Which model proves correct will largely determine this week's US price direction.

China & Stocks
An important caveat on global wheat stocks — approximately 40% of world wheat stocks are estimated to be held in China, making accurate assessment of freely available global supply difficult. If Chinese stocks are strategic reserves rather than commercially available supply, the effective global balance sheet is considerably tighter than headline numbers suggest.

UK Harvest
Yorkshire spring barley reporting good quality in early results. Yields not yet confirmed but quality indications are encouraging for premium milling and malting markets.

Opinion
The MARS bulletin cutting every single EU crop simultaneously is the institutional confirmation that has been building all season. When the European Commission's own crop monitoring agency revises corn yields down 6.1% in a single monthly update, the comfortable supply narrative is officially over. EU total grain production now 1% below the five-year average with corn and sunflower 6-7% below — and another heatwave is due in France this week.

The 40% of world wheat stocks held in China is the number that should be attached to every global stock headline as a mandatory caveat. If the commonly cited global stock figures include Chinese strategic reserves that will never reach world markets, the effective freely available supply is dramatically tighter than published data suggests. This is not a new observation — but it becomes more significant as the balance sheet tightens from every other direction simultaneously.

Ukrainian export capacity down a third, Russian down a quarter, with repair timelines uncertain — and the question of whether Ukrainian and Russian farmers will plant wheat this autumn given congested ports, fertiliser shortages and conflict risk. The 2027 crop is being determined right now in decisions that are increasingly pointing toward reduced area. The market's flat curve between November 2026 and November 2027 futures is not wrong.

Yorkshire spring barley showing good quality is the one genuinely positive domestic data point of the week. In a market desperate for quality grain, clean malting barley from a Yorkshire harvest commands real premium value — do not undersell it.

Oil at $85, Iran pause holding, Zelensky meeting Trump today. Every previous peace signal in this conflict has been followed by resumed hostilities. The market is right to be sceptical while remaining alert.
