Disruption to Russian and Ukrainian grain exports is adding to rising food, fuel and fertiliser costs. Britain may face another squeeze on household budgets, but the consequences for poorer countries could be far more severe.
The war involving Russia and Ukraine is threatening something that rarely attracts as much attention as oil: the international supply of grain on which millions of people depend.
Attacks on ports and shipping routes in the Black Sea have disrupted exports from two of the world's important agricultural suppliers. At the same time, conflict in the Middle East has affected energy and fertiliser supplies, while adverse weather is adding uncertainty to harvests elsewhere.
The result is a worrying combination of rising costs and greater uncertainty over whether food will reach the countries that need it most.
For British households, the immediate concern is another increase in the cost of living. For some of the world's poorest countries, the consequences can be much more serious, affecting whether families can afford enough food to eat.
Russia and Ukraine remain central to the grain trade
Russia and Ukraine are major exporters of wheat and other agricultural commodities. Ukraine is also an important supplier of maize and sunflower oil. Their exports serve customers across North Africa, the Middle East and Asia, as well as other parts of the world.
The Black Sea is therefore more than a regional shipping route. It is an important part of the infrastructure supporting the international food system.
The renewed disruption to maritime trade has forced exporters and importers to seek alternative routes. Ukraine faces restrictions on its normal seaborne export capacity, while Russia has been redirecting more shipments through Baltic ports.
On 28 October, Reuters reported that Russia had begun loading grain at the Arctic port of Murmansk, seeking another route to overseas customers. Its first reported shipment was 3,400 tonnes, with further shipments planned.
Such efforts demonstrate that trade has not stopped altogether. But alternative ports and transport routes cannot necessarily replace the capacity, cost and efficiency of established shipping arrangements.
The United Nations Food and Agriculture Organization (FAO) reported that international wheat prices rose by 6.3% in September 2026 compared with August. Its cereal price index increased by 5.1% over the month and was 17.2% higher than a year earlier.
These are international commodity prices, not increases in supermarket prices. Nevertheless, they provide an early indication of the pressures facing food producers and buyers.
The FAO also forecasts that global cereal production in 2026 will fall by 2.1% compared with 2025. Although the expected harvest would still be the second largest on record, cereal trade is forecast to decline, partly because of restrictions on Black Sea shipping.
That distinction matters. The world may produce enough grain overall, yet particular countries can still struggle to obtain supplies at an affordable price.
Why poorer countries are most vulnerable
Higher grain prices do not affect every country equally.
In Britain, most households can usually continue buying bread, pasta and other staples even when prices rise. The extra cost may mean reducing other spending, postponing a purchase or drawing on savings.
For a family living close to subsistence in a low-income country, there may be no equivalent room for adjustment.
Food can account for a very large proportion of household expenditure. When the price of a staple rises, families may have to buy less, switch to less nutritious food, borrow money or sell possessions to cover basic needs.
Children, pregnant women and people already suffering from malnutrition are particularly vulnerable to the consequences.
Countries that rely heavily on imported wheat are especially exposed. Egypt, for example, is a major wheat importer, while countries across North Africa and the Middle East depend on international markets to varying degrees. Some countries in sub-Saharan Africa are also highly vulnerable to changes in the price of imported food, although their diets and dependence on particular crops differ.
The problem is not limited to the price of grain itself. Governments must find the foreign currency needed to pay for imports. If their currencies weaken against the US dollar, food becomes more expensive in local terms even if the international price rises only modestly.
Governments may subsidise bread or other staples to protect poorer households. But subsidies become more expensive when import bills increase, placing additional pressure on public finances already stretched by debt, weak economic growth or conflict.
The World Food Programme has warned that disruption to the Black Sea, Red Sea and Strait of Hormuz shipping routes threatens food security by affecting the movement of food, fuel and fertiliser. It reported in October that the cost of a basic diet in Sudan had risen by almost 40% since February 2026, driven partly by higher fuel costs.
This illustrates how an international energy or shipping crisis can quickly become a local food crisis.
The danger of a chain reaction
The grain crisis cannot be separated from the wider energy crisis.
Farmers need fuel to operate machinery and transport crops. Fertiliser production depends heavily on natural gas, while shipping and food processing also require energy.
When energy costs rise, the cost of growing and distributing food increases. If farmers respond by using less fertiliser or planting fewer crops, the consequences can extend into future harvests.
There is also a risk that countries react individually to protect their own supplies. Export restrictions may seem attractive to governments worried about domestic prices, but if several major exporters restrict trade at once, the amount of grain available to international buyers can fall further.
The result can be a damaging cycle: higher prices encourage governments to intervene, interventions restrict supplies, and prices rise further.
The international response therefore matters. Keeping trade routes open, maintaining reliable information about grain stocks and avoiding unnecessary restrictions on food exports can help prevent a difficult situation from becoming much worse.
Is another food-price shock inevitable?
Not necessarily.
The FAO's forecasts indicate that global cereal stocks remain substantial, providing some protection against supply disruptions. Other exporting countries can also redirect supplies to meet demand, although replacing the volume and quality of grain from the Black Sea may not be straightforward.
The Center for Global Development, in an analysis published in September, likewise noted that stocks of wheat and maize among major exporters remained relatively high by historical standards. It cautioned, however, that war, expensive fertiliser and possible weather-related crop losses could leave markets less able to absorb further shocks.
That is the central uncertainty. The world has buffers, but several risks are occurring together.
If shipping routes reopen and harvests elsewhere are satisfactory, grain prices could stabilise. If attacks continue, energy costs remain elevated and weather damages crops, the pressure could become more persistent.
Even when international prices eventually fall, consumers may not see an immediate reversal. Food businesses buy supplies at different times, and wages, transport, packaging and other costs also influence retail prices.
Britain should not overlook the international consequences
The UK is not wholly dependent on Russian or Ukrainian grain. Domestic production and supplies from other exporting countries offer some protection. But Britain remains exposed to international commodity markets, and its own wheat harvest has been below average in recent years.
Higher grain and energy prices could therefore add to pressure on bread, processed foods, meat and other products, although the timing and scale of any increases remain uncertain.
For households already struggling with the cost of living, another rise in food prices would be unwelcome. For poorer countries, the same international shock can mean something far more fundamental: fewer meals, worsening nutrition and greater dependence on emergency food aid.
The international community has faced this problem before. The food-price crisis following Russia's full-scale invasion of Ukraine in 2022 demonstrated how quickly a disruption in one region can affect markets worldwide.
The lesson is not that the world is about to run out of food. It is that producing enough food globally does not guarantee that everyone can afford it or obtain it reliably.
The danger is that food becomes increasingly expensive precisely where people have the least ability to pay. As the conflicts affecting energy and shipping continue, the cost of the next meal may become one of their most consequential effects.
