UK food-price inflation has fallen far below the levels expected earlier in 2026. Some of the pressures behind those expectations have eased, while competition and weak consumer demand are making price increases harder to pass through.

Other costs may still reach supermarket shelves with a lag, leaving cost pass-through as the critical issue for retailers during the rest of the year.

UK food-price inflation has so far defied expectations of a sharp acceleration in 2026.

Food and non-alcoholic beverage prices rose by 1.7% in the 12 months to June, down from 2.2% in May and the lowest annual rate since August 2024, according to the Office for National Statistics (ONS). Prices fell by 0.2% between May and June.

That is a markedly different outcome from the outlook earlier in the year.

In April, the Bank of England projected food-price inflation reaching 4.6% by September. Supermarkets reporting to the Bank's regional Agents were also expecting substantially higher inflation later in 2026.

Those expectations have subsequently moderated. In July, supermarkets reporting to the Agents expected food inflation to peak at around 4%–5% during 2026, while the Bank's own latest projection put food-price inflation at nearly 3.5% in December.

The feared surge has therefore not arrived.

Explaining why is more difficult.

Some pressures underlying the earlier outlook have weakened. Other costs could still pass through with a lag. At the same time, the Bank's business intelligence provides evidence of fragile consumer demand, intense supermarket competition and resistance to some supplier price increases.

All three mechanisms could help explain why consumer food inflation has remained lower than previously expected.

The available evidence does not allow their relative importance to be reliably quantified.

That distinction is central to the outlook for the rest of 2026.

What the data establish

The first half of the year has produced a clear easing in food-price inflation.

Food and non-alcoholic beverage inflation was 4.5% in December 2025. By June 2026, it had fallen to 1.7%.

The monthly data were also subdued. Food and non-alcoholic beverage prices fell by 0.2% between May and June, compared with a 0.3% increase in June 2025.

The British Retail Consortium's Shop Price Index points in the same direction, although it is compiled differently from the ONS consumer-price measure.

BRC food inflation fell from 2.7% in May to 2.4% in June. Fresh-food inflation fell from 3.4% to 2.8%, while ambient-food inflation increased from 1.6% to 1.9%.

The two measures should not be directly compared as though they measure the same thing. But both show food-price inflation slowing during the first half of 2026.

That does not mean food has become cheap.

Lower inflation means prices are increasing more slowly; it does not mean they have returned to previous levels.

Government analysis shows that UK food and non-alcoholic beverage prices increased by 31.6% between January 2021 and August 2024, while annual food-price inflation peaked at 19.2% in March 2023.

The recent improvement is therefore a slowdown in further price increases, not a reversal of the large rise in food prices experienced earlier in the decade.

Why has inflation undershot earlier expectations?

There is no single answer supported by the available data.

Instead, the evidence points towards three mechanisms that could have contributed: some underlying pressures have eased; some costs may not yet have reached consumers; and commercial conditions are making some price increases difficult to pass through.

The first is visible in the Bank of England's changing outlook.

Its July assessment projected food-price inflation at nearly 3.5% in December, below its earlier projection. The Bank attributed the revision partly to weaker recent food-price data, easing agricultural commodity pressures and developments in wholesale energy markets.

That matters because it means the difference between earlier expectations and current inflation cannot simply be attributed to supermarkets absorbing higher costs.

Some of the underlying assumptions themselves have changed.

But that is not the whole explanation.

Costs do not pass through automatically

Food prices are the end result of a long supply chain.

Energy, agricultural commodities, fertiliser, labour, transport, packaging and imported ingredients can all affect production and distribution costs. A change in any one of them does not necessarily appear immediately or proportionately in supermarket prices.

Contracts, inventories and purchasing arrangements can delay transmission. Suppliers and retailers negotiate over increases. Retailers must also decide whether shoppers will accept higher prices.

That creates a distinction between a cost shock and its eventual pass-through to consumers.

The Bank's July business intelligence provides evidence that this process is currently important.

Supermarkets reported fragile consumer demand and intense competition, while focusing on controlling costs and resisting some supplier proposals for price increases.

The Bank's Agents also reported that own-label manufacturers were concerned about losing contracts with major supermarkets, while branded-goods producers feared that consumers would switch to cheaper alternatives.

These reports do not prove that competition is the principal reason food inflation has fallen to 1.7%.

They do, however, provide direct evidence of commercial pressure against passing some increases through to customers.

A retailer facing higher costs can attempt to negotiate with suppliers, reduce costs elsewhere, alter promotions or accept pressure on margins rather than immediately increasing shelf prices.

The Bank's Agents have reported squeezed margins among firms, with margin recovery expected to take longer than previously thought. That evidence should not, however, be interpreted as a precise measure of how much cost retailers are absorbing.

The available evidence therefore supports the existence of mechanisms capable of slowing pass-through. It does not establish how much of the current inflation undershoot can be attributed to each mechanism.

Upstream pressures are not all moving in the same direction

The cost picture itself also argues against a simple narrative of steadily increasing pressure.

ONS producer-price data show that domestic food input prices were 1.0% lower in June than a year earlier, while imported food input prices were 0.5% higher. On a monthly basis, domestic food input prices fell by 1.2%, while imported food input prices rose by 0.3%.

These measures do not capture the entire cost base faced by food manufacturers or retailers. Labour, energy, transport, property and other operating expenses also matter.

But the divergence is important.

If some inputs are falling while others are rising, there is no reason to expect every part of the food supply chain — or every food category — to experience the same inflationary pressure.

It also means that low consumer food inflation cannot automatically be interpreted as evidence of widespread cost absorption. In some cases, the underlying pressure may simply have weakened.

What the 4%–5% supermarket expectation actually means

One number requires particular care.

In July, the Bank's Agents reported that supermarkets expected food-price inflation to reach a 2026 peak of around 4%–5%.

That is not a Bank of England forecast.

It is business intelligence gathered from supermarkets by the Bank's regional Agents.

The Bank's own central projection was lower, putting food-price inflation at nearly 3.5% in December.

Nor does a 4%–5% annual inflation rate mean supermarket prices would rise by another 4%–5% between June and the peak.

Annual inflation measures the percentage difference between prices and their level in the corresponding period a year earlier. Changes in the annual rate therefore reflect both current price movements and the prices against which they are being compared.

The supermarket expectation is nevertheless useful forward-looking evidence.

It shows that supermarkets were still expecting food-price inflation to accelerate from June's 1.7% rate.

Whether that expectation proves accurate is a different question.

What we know — and what we do not

At this point, the evidence supports several relatively firm conclusions.

Food-price inflation has fallen substantially during 2026 and has undershot expectations held earlier in the year.

The Bank has subsequently reduced its own projection, citing weaker recent food-price data alongside changes in agricultural commodity and wholesale energy conditions.

There is also direct business intelligence showing fragile consumer demand, intense supermarket competition and resistance to some supplier price increases.

What the evidence cannot establish is how much of the inflation undershoot is attributable to weaker underlying cost pressures, how much reflects delayed transmission and how much results from retailers or suppliers negotiating, absorbing or offsetting increases.

That uncertainty matters because each explanation implies a different outlook.

If the underlying pressure has largely disappeared, inflation could remain subdued.

If the pressure exists but has merely been delayed, inflation could accelerate as costs move through contracts and supply chains.

If costs are currently being resisted or absorbed, the outlook will depend partly on how long businesses can continue doing so.

Three plausible paths for the rest of 2026

These are scenarios, not forecasts.

1. Inflation remains relatively subdued

If agricultural commodity and energy pressures remain manageable and supermarket competition stays intense, food inflation could remain below the levels feared earlier in the year.

That would extend the pattern seen during the first half of 2026.

Fragile demand and consumers' ability to switch between retailers, brands and own-label products would continue to limit pricing power.

2. Delayed costs begin reaching consumers

A second possibility is that some costs already identified by retailers and suppliers begin to reach shelf prices with a lag.

The Bank continues to expect higher energy costs to feed into food prices and projects annual food-price inflation at nearly 3.5% in December.

Under this scenario, inflation would accelerate from June's 1.7% rate without approaching the extreme rates experienced during the 2022–23 food-price shock.

3. Several pressures strengthen simultaneously

A more adverse scenario would involve higher energy costs coinciding with stronger imported-cost pressures, adverse agricultural conditions or reduced scope within the supply chain to negotiate or offset increases.

That would increase the risk of a stronger rebound in food inflation.

A peak of around 4%–5% remains within the range currently expected by supermarkets reporting to the Bank's Agents, although the available evidence does not establish that this combination of risks is the basis for those expectations.

It remains a risk scenario rather than a prediction.

Weather is a risk, not yet proof of higher food inflation

Weather provides a good example of why potential cost pressures need to be distinguished from demonstrated consumer-price effects.

Adverse conditions can reduce crop yields and supplies of individual products, potentially increasing prices in affected categories.

The Bank has identified weather-related events as an upside risk to global food prices. Current UK drought conditions provide another reason for retailers to monitor agricultural supply closely. Reuters reported in August that England and Wales had experienced their driest July on record, with concerns about the consequences for domestic agriculture.

But agricultural disruption does not automatically translate into a material increase in the overall UK food-inflation rate.

Its effect depends on which products are affected, the scale and duration of the disruption, alternative sources of supply, import costs and how much of any increase ultimately passes through the supply chain.

Weather should therefore be treated as an upside risk to the outlook, rather than evidence that a nationwide food-price surge is already under way.

What retailers should watch

For retailers, the key issue during the remainder of 2026 is cost pass-through.

Producer and input prices can show whether upstream pressure is strengthening. Energy and agricultural commodity markets affect production costs. Import prices and sterling matter for internationally sourced products.

Retail behaviour provides another signal.

If supermarkets continue resisting supplier increases while promotional competition remains intense, some pressures may take longer to reach shoppers.

If broader price increases begin appearing alongside evidence of strengthening upstream costs, the case for renewed food inflation would become stronger.

Consumer behaviour matters as well.

Branded-goods producers have already told the Bank's Agents that they are concerned about shoppers switching to cheaper alternatives.

That affects pricing power. When shoppers can switch supermarket, brand or product tier relatively easily, businesses have less freedom to pass through increases without risking volumes.

None of these indicators should be considered in isolation.

The important evidence will be whether several begin moving in the same direction.

A better outlook — but not an all-clear

The evidence available by mid-August supports a narrower conclusion than either “the food-price threat has disappeared” or “another inflation surge is imminent”.

The surge feared earlier in 2026 has not materialised.

Annual food and non-alcoholic beverage inflation fell to 1.7% in June, its lowest rate since August 2024. The Bank of England has reduced its own projection and now sees inflation at nearly 3.5% in December, while supermarkets reporting to its Agents expected a 2026 peak of around 4%–5%.

Those figures point towards some renewed inflation later in the year, but considerable uncertainty remains over its scale.

The evidence also cautions against attributing the undershoot to any single cause.

Some upstream pressures have eased. Some costs may still be travelling through the supply chain. And there is evidence that weak demand, competition and supplier negotiations are making increases harder to pass through.

The available data cannot reliably determine the relative contribution of those effects.

For retailers, that makes the next stage of the story less about forecasting a single inflation number and more about watching where costs are emerging, whether they persist and how much of them reach the shelf.

The capacity of retailers and suppliers to offset persistent increases through negotiations, efficiencies or margins is unlikely to be unlimited. Equally, the first half of 2026 demonstrates that higher costs do not translate mechanically or immediately into consumer prices.

For now, the evidence supports a more moderate outlook than was feared earlier in the year.

Food inflation could accelerate again during the remainder of 2026. But the evidence currently supports a risk of renewed upward pressure — not a return to anything resembling the 2022–23 food-price shock.
