UK households faced an unexpected increase in grocery inflation last month, ending four consecutive months of decline, according to new market data. Analysts warn that ongoing geopolitical tensions could intensify price pressures in the months ahead.

Inflation Trends Reverse

Grocery price inflation rose to 4.3% in the four weeks to 22 February, up from 4% in January, after previously falling from 4.7% in December, according to research from Worldpanel by Numerator.

The rise comes at a time when many families are already under strain from the broader cost-of-living squeeze, raising concerns about renewed pressure on household budgets.

Energy Shock Fears

Economic observers have warned that a prolonged conflict in the Middle East could disrupt oil and gas supplies, potentially triggering a significant inflationary spike.

In comments reported by the Financial Times, Philip Lane, chief economist at the European Central Bank, said higher energy prices would place upward pressure on inflation in the near term and negatively affect economic growth.

Rising oil and gas costs could:

·        Increase fuel prices for UK drivers

·        Push up household electricity and gas bills

·        Add to broader inflation across goods and services

Retail and Consumer Spending Trends

Despite inflation concerns, consumer spending patterns show continued engagement around seasonal events.

·        Chocolate prices are up 9.3% year-on-year, though inflation in the category is easing, according to Worldpanel by Numerator.

·        Sales of pre-made pancake mixes surged 114% ahead of Shrove Tuesday.

·        Ingredient purchases rose sharply: flour (+34%), sugar (+17%), lemons (+70%).

·        Nearly 12% of households purchased premium Valentine’s Day meal deals on Friday alone.

Spending on high-end meal deals priced at £10 or more reached £39 million in the week before Valentine’s Day — seven times higher than the previous week.

Online Grocery Growth Continues

Online grocery shopping continued to expand, with sales up 9.7% year-on-year. More than 18 million orders were placed over the four-week period, making online purchases account for 13% of total grocery sales, the highest level since July 2021.

According to Worldpanel by Numerator, online shopping is increasingly appealing across income groups, though adoption remains strongest among more affluent households in London and the south-east.

Supermarket Performance Overview

Market performance over the latest 12-week period shows mixed results:

·        Ocado remained the fastest-growing grocer, with 15.1% sales growth and a 2.1% market share.

·        Lidl recorded double-digit growth for the 12th consecutive month, up 10%, with a 7.8% share.

·        Tesco increased sales by 4.5%, reaching a 28.5% market share.

·        Sainsbury's grew sales by 5.2%, raising its share to 16.1%.

·        Waitrose achieved its strongest growth since March 2021, up 5.6%, with a 4.8% share.

·        Asda reported a 2.6% decline in sales.

·        Co-op saw sales fall 1.6%.

Separately, Greggs reported a near-18% drop in pre-tax profits to £167.4m, though it noted that easing inflationary pressures could support future consumer spending.

Outlook

While inflation levels remain lower than last year’s peak, renewed energy risks and geopolitical instability could reverse recent gains. Analysts suggest that sustained disruptions in global energy markets would likely impact both inflation and economic growth across the UK and eurozone.
