More wheat, less trade as Black Sea logistics fail

The USDA's September estimates contain two numbers that point in opposite directions. World wheat supplies for 2026/27 were raised by 3.5 million tonnes to 1,103.0 million tonnes, due to larger crops in Australia, Canada and Ukraine. In the same report, world wheat trade was cut by 0.9 million tonnes to 211.8 million tonnes, with the reductions falling on Russia, Ukraine, Kazakhstan and Egypt. The World Agricultural Supply and Demand Estimates of 11 September explain the second number in one sentence. Russia and Ukraine's exports are reduced due to weak August shipments, as the war in the Black Sea region hampers logistics.

The grain exists. The routes to move it are the problem. That distinction sets the wheat market apart from a straightforward shortage, and it explains why prices climbed to a three-and-a-half-year high in late August, even though the season is the second-largest on record for global production.

Ukraine has a record crop and falling exports

The clearest illustration is Ukraine. USDA raised its production forecast by 0.6 million tonnes to 26.0 million tonnes on a record yield as the harvest nears completion. In the same month, it cut Ukrainian exports by 1.0 million tonnes to 12.5 million, and raised the country's projected ending stocks from 4.8 to 6.1 million tonnes. More wheat is being harvested in Ukraine than a month ago, and more of it is expected to stay there.

Russia shows the same pattern at larger scale. Its crop was trimmed by 0.5 million tonnes to 88.0 million, but its exports were cut by 3.0 million tonnes to 43.0 million, and its ending stocks rose by 2.5 million to 16.09 million tonnes. Between them, the two Black Sea exporters lost 4 million tonnes of projected exports in a single monthly revision, while adding 3.8 million tonnes to the stocks sitting in their own storage. FAO's Cereal Supply and Demand Brief, published earlier in the month, described the same effect, with wheat reserves building in Russia and Ukraine behind restricted export routes.

Kazakhstan, the third Black Sea and Caspian exporter, was cut by 1.0 million tonnes to 15.0 million on lower harvested area, with exports lowered to 9.5 million tonnes.

Australia, Canada and Argentina pick up part of the slack

The increase in supply came from the other side of the world. Australia's production was raised from 3.0 million tonnes to 31.0 million tonnes in the latest ABARES quarterly report, with very favourable conditions in South Australia and Victoria and improving moisture in Western Australia. Its projected exports rose from 22.0 to 23.5 million tonnes. Canada's production was raised from 1.0 million tonnes to 36.0 million tonnes under continued favourable conditions across the Prairie Provinces, with exports up 1.5 million tonnes to 30.0 million tonnes. Argentina added 0.5 million tonnes to both production and exports.

Those three gains, totalling 3.5 million tonnes of extra exports, only partly offset the 4.5 million tonnes lost from Russia, Ukraine and Kazakhstan. The net result is that world trade falls even as supply rises. Set against the 2025/26 season, when trade reached a record 227.6 million tonnes, the 2026/27 figure of 211.8 million represents a drop of almost 16 million tonnes, or 7%, in the volume of wheat expected to cross a border.

Buyers are paying for the origin

The trade cut lands hardest on the importers most dependent on Black Sea grain. USDA lowered its projected imports for North Africa by 1.55 million tonnes to 27.55 million tonnes, a reduction driven by Egypt. Reuters, reporting on 20 August, put the exposure in context. Egypt, the world's largest wheat importer, sourced more than 82% of its wheat from Russia and Ukraine in the first half of 2026. Indonesia had contracted about 600,000 tonnes from former Soviet exporters for the July to September shipment. Asian processors as a group had booked 2 to 2.5 million tonnes of Black Sea wheat for the same window, equivalent to 30% to 50% of their import needs, and were turning to Australia, Argentina, Romania and Bulgaria for cargoes that might not arrive.

Trade has begun to reroute in ways that would have looked unusual a year ago. French operators prepared a 67,000-tonne cargo for Sudan, a market France had not supplied with wheat for nearly two decades. Jordan cancelled several wheat and barley tenders in August amid high prices and shipping risk. Grain exports through Ukraine's Black Sea ports fell 75% in the first two weeks of August compared with the same period last year, and UkrAgroConsult put Ukraine's wheat exports at 40% below a year earlier by early September. Buyers who relocate demand to Australian or Argentine origin are paying a premium for a cargo that will actually load, which is what a logistics constraint looks like in price.

What the price has done

Chicago wheat futures rose more than 17% between the start of July and 20 August, according to Reuters, and reached a three-and-a-half-year high in late August as Moscow rejected a moratorium on Black Sea port attacks. Prices then retreated through the first half of September as diplomatic contacts produced meetings without a ceasefire or any restoration of grain flows, trading roughly 5% to 8% below the peak by 11 September. FAO's Food Price Index recorded wheat quotations 2.6% higher in August and 15.0% above a year earlier, citing Black Sea disruption, weaker European production prospects, and a softer dollar, the combination of which was cited as the reason world food prices reached their highest level since November 2022.

The retreat has been read in some quarters as the unwinding of the risk premium. The WASDE trade line suggests a narrower interpretation. Prices came down because the market stopped expecting the situation to worsen, while the tonnage stayed where it was. The 211.8 million tonne trade forecast was published on the same day the retreat was underway.

What history says about the gap between having wheat and moving it

The distinction between supply and trade has decided the wheat market before. When the Black Sea Grain Initiative restored part of Ukraine's exports in 2022/23, Chicago wheat fell 32.8% over the season. It rose only 4.2% in 2023/24 as Ukraine built a replacement shipping corridor, and fell 6.9% in 2024/25 as exports continued despite ongoing attacks. Across those three seasons, the war never stopped, but the wheat kept moving, and the market removed most of the premium it had priced in.

That record is the reason to watch the trade line rather than the price. USDA's figures describe 1,103 million tonnes of wheat worldwide, with 276.3 million tonnes expected to be in storage at the end of the season and 211.8 million tonnes expected to trade. The first two numbers rose this month. The third fell. For a Greek importer or a Mediterranean miller, that combination means the question for 2027 contracts is less about how much wheat exists than about which origins can guarantee delivery, and what the guarantee costs.
