25th July 2026
Britain's food-price inflation has just given households some welcome relief.
But there is a danger that the improvement could prove temporary.
Europe's exceptional heatwave has damaged crops at exactly the wrong time, while the continuing oil and energy crisis is threatening to push up the cost of producing, processing and transporting food.
The result could be another squeeze on supermarket prices — and this time the effects may not become obvious until autumn and winter.
Food prices are falling — for now
The latest official figures from the Office for National Statistics show food and non-alcoholic beverage prices were 1.7% higher in June 2026 than a year earlier, down from 2.2% in May.
On a monthly basis, food prices actually fell by 0.2%.
That sounds encouraging, and it is. But it is important to remember that inflation measures the rate at which prices are changing, not whether prices have returned to where they were several years ago.
The British Retail Consortium's figures also showed food inflation easing to 2.4% in June, with fresh food inflation at 2.8%.
So shoppers have been getting a little breathing space.
The question is whether it will last.
Europe's heatwave has already damaged the harvest
The most worrying development is what happened to crops across Europe during June.
The heatwave struck during crucial stages of development for crops including wheat and maize. France, Hungary and several other countries were particularly badly affected.
Analysis of European grain forecasts suggests that almost 9 million tonnes of production have been lost from forecasts for the EU and UK, with the value of the lost grain estimated at around €2 billion.
That is a substantial reduction in a market which supplies food, animal feed and raw materials to the wider European economy.
And there is a particular problem with maize.
It is not simply something that ends up on our plates. Maize is also an important component of animal feed.
That means a poor maize harvest can eventually affect the price of:
chicken
pork
eggs
milk
dairy products
beef
The effect can therefore spread much further through the food chain than the original crop.
The important word is "delay"
This is where consumers can easily be misled.
A heatwave does not necessarily produce an immediate supermarket price rise.
Farmers may have already sold some of their crops.
Food manufacturers may have contracts covering supplies for months ahead.
Supermarkets may have fixed prices with suppliers.
There may also be grain stocks available to absorb part of the shortage.
So the sequence can look something like this:
Heatwave → smaller harvest → higher commodity prices → higher costs for farmers and processors → higher wholesale prices → supermarket price negotiations → higher prices for shoppers.
That process can take months.
This is why autumn and winter could be more important than July or August when it comes to the eventual effect on household food bills.
Then comes the oil problem
The crop damage would be worrying enough by itself.
But Britain and Europe are also dealing with another problem — energy.
Oil is not simply used to put fuel into cars.
Modern agriculture depends heavily on energy.
Farm machinery needs diesel. Crops have to be harvested and transported. Grain may need drying and storage. Food factories consume electricity and gas. Goods then have to be transported to distribution centres and supermarkets.
And there is another particularly important connection:
Fertiliser
Energy prices have a major influence on the cost of producing fertiliser. If energy becomes more expensive, farmers can face higher costs before they have even planted the next crop.
That creates the possibility of a second wave of food inflation.
Oil can reach the supermarket without appearing on the price label
This is something worth remembering when oil prices rise.
The effect is not limited to the petrol station.
Imagine a loaf of bread.
The wheat has to be grown.
The farmer needs machinery.
The grain is harvested and transported.
It may need drying and storage.
It is milled into flour.
The flour is transported to the bakery.
The bread is manufactured, packaged and transported again.
Finally it reaches the supermarket.
Oil and energy can therefore be embedded in the price of the loaf at many different stages.
The same applies to almost everything else in the supermarket.
This could be a double hit
That is what makes the present situation different.
We could potentially have:
First shock:
A heatwave reduces European crop yields.
Second shock:
Higher oil and energy prices increase the cost of producing and moving what remains.
The two problems can reinforce each other.
JPMorgan has warned that the combination of a potentially severe El Niño weather pattern and higher energy prices could increase global food inflation. Its analysis suggests El Niño alone could add around 0.7 percentage points to global food inflation, while the combination with higher diesel, fertiliser and packaging costs could increase the impact to roughly 1.3–1.5 percentage points.
That does not mean Britain will experience those exact increases.
But it demonstrates why economists are watching the combination of weather and energy rather than looking at either problem in isolation.
Which foods could be most vulnerable?
There are several areas worth watching over the next six months.
Bread and cereals
Wheat prices are particularly important because wheat is used for bread, flour, cereals and numerous processed foods.
A smaller European harvest could put additional pressure on prices if import demand increases.
Meat
Animal feed is a major cost for livestock producers.
If maize and other feed grains become more expensive, the effect can eventually reach poultry, pork, eggs and dairy products.
Cooking oils
Oilseed crops such as rapeseed can also be affected by weather conditions.
That matters not only for cooking oils but also for food manufacturing.
Fruit and vegetables
These are particularly vulnerable to extreme weather because crops can be damaged directly and production can require more irrigation.
Transport and refrigeration also add energy costs.
Processed food
This is perhaps the least obvious category.
The price of a processed food product reflects not just its ingredients but also energy, packaging, refrigeration, transport and distribution.
If several of those costs rise together, the impact can eventually become visible on supermarket shelves.
Britain has one advantage — but it isn't immune
The UK has a relatively sophisticated food supply chain and supermarkets are highly competitive.
That can delay the transmission of higher costs to consumers.
Retailers can also absorb some increases in their margins or switch suppliers.
The June figures demonstrate that competition is still helping to restrain food inflation.
But there is a limit to how long businesses can absorb rising costs.
If wheat, maize, fertiliser, diesel, packaging and transport all become more expensive at the same time, eventually somebody in the supply chain has to pay.
And ultimately that can mean the consumer.
The danger is another "slow burn" inflation problem
This is perhaps the biggest concern.
Britain has already experienced a huge increase in the cost of living over the past few years.
Even if food inflation is now only 1.7%, that does not mean food has become cheap again.
It means that prices are rising more slowly from an already much higher base.
For a household struggling to balance food, heating, housing and transport costs, another 3%, 4% or 5% increase in food prices would matter.
And it would matter particularly to households that have already cut back on what they buy.
What should shoppers watch?
The next few months could tell us whether the present food-price calm is going to last.
The warning signs I would watch are:
wheat and maize prices
European harvest forecasts
fertiliser prices
diesel prices
oil prices
supermarket food inflation
fresh food prices
animal-feed costs
the cost of transporting food
If several of those start moving upwards together, the likelihood of higher supermarket prices later in the year increases.
The real concern for Britain
There is no reason to predict food shortages or a return to the extraordinary inflation seen during the worst of the cost-of-living crisis.
Europe still has substantial food production, global grain markets remain capable of supplying shortages, and supermarkets have considerable purchasing power.
But that does not mean there is nothing to worry about.
The bigger danger is a new period of persistent food inflation arriving just as households are beginning to believe that the worst is over.
The June figures offered some good news.
But the harvest now developing across Europe, combined with the uncertain oil market, could determine whether that good news lasts.
The first oil shock hits the fuel pump. The second can arrive through the supermarket.
That is why the next few months could be particularly important for British household budgets.
The food-price story of winter 2026 may already be beginning in Europe's fields even though shoppers cannot see it yet in the supermarket.
