Explainer · last look 12 September 2026 Why does Black Sea trouble make UK bread and feed dearer? Wheat, maize and sunflower oil are bought on a world market. Russia and Ukraine together sell more than a quarter of the wheat the world exports. When ships and quays around Odesa or Novorossiysk are hit at harvest, that world price can jump before a British loaf looks any different. Britain grows a lot of wheat. It still buys cover. Defra recorded £601 million of unmilled wheat imports in 2025, and £3.5 billion of animal feed. Ukraine supplied about two-thirds of the UK’s crude sunflower-oil import value that year. |
How quickly does a Black Sea shock reach a British kitchen?
|
Days Wheat futures. News of a struck grain ship is enough. |
Weeks Feed contracts and cooking-oil cover. Farms and mills. |
Months A dearer loaf or bottle if the tightness holds. |
What does Britain actually buy?
| Line | Official figure | Source |
| Unmilled wheat imports, 2025 | £601 million, down 12% on 2024 | Defra, Agriculture in the United Kingdom 2025, ch.13 |
| Cereals and cereal products | £7.0 billion of imports | Defra AUK 2025 |
| Animal feed | £3.5 billion of imports | Defra AUK 2025 |
| Maize import need, 2025/26 | about 2.2 million tonnes | AHDB, January 2026 |
| Crude sunflower oil from Ukraine | about two-thirds of UK import value in 2025 | UK trade / Comtrade breakdowns |
Does a good British harvest cut us off from that price?
| What the field does A decent UK harvest fills a lot of the mill. Two weaker harvests in a row cut exports to almost nothing — Defra logged only £43 million of unmilled wheat exports in 2025. |
What the market still does Mills and feed plants buy on world prices. Canadian, French, Argentine and Black Sea cargoes move together. A shock at Odesa still changes the number a Lincolnshire miller is offered. |
The loaf can be milled from British grain and still get dearer. The field and the world price are tied.
What left the Black Sea in summer 2026?
| Late-July shipments against a year earlier (IFPRI) | |
| Still moving ~60% | Missing against last year ~40% |
| Measure | Summer 2026 |
| Wheat versus January 2026 | about 25% higher; two- to three-year highs |
| FAO Food Price Index, August 2026 | 133.3 — highest since March 2022 |
The crop was in the barns. The door out was the problem. Quays at Greater Odesa and on the Russian side were hit in the same harvest weeks. Call numbers at Ukrainian ports fell sharply in early August. The UN named Black Sea uncertainty among the reasons the food index rose.
Which British foods feel this first?
| On the farm or in the mill | Then on the label |
| Wheat cover | A dearer loaf, later |
| Maize and sunflower meal | Dearer chicken and other rations, then the meat counter |
| Sunflower oil | The bottle on the shelf, and some processed foods |
If the ports stay awkward into winter, will the bakery close?
UK mills have stocks and more than one origin. Cooking oil can be bought from the EU and from South America as well as from Ukraine. The honest outlook if loadings stay tight is dearer feed, a dearer bottle, then a dearer loaf. Other countries’ harvests still exist. A stripped bread bay empties a full warehouse faster than a Bosporus delay.
What should a miller, a farmer or a buyer do with this?
| If you | Treat the price as |
| Mill wheat or mix feed | Live. Cover before the silo looks empty. |
| Buy cooking oil for a brand | Tied to Ukraine more than most shoppers think. Keep a second origin on paper. |
| Watch a till | Expect the label to move before the shelf looks bare. |
