UK inflation shot up unexpectedly last month as vegetable shortages pushed food prices to their highest rate in more than 45 years, according to official figures.

The Office for National Statistics (ONS) revealed Consumer Prices Index (CPI) inflation rose to 10.4 per cent in February from 10.1 per cent in January.

Most economists were expecting CPI to fall to 9.9 per cent in February.

The surprise jump in inflation comes after food and non-alcoholic drinks prices rose by 18 per cent year-on-year last month, up from 16.7 per cent in January and the highest since August 1977.

The ONS said price inflation of food, including non-alcoholic drinks, raced higher to 18.3 per cent from 16.8 per cent.

Shortages of vegetables such as tomatoes and peppers in recent weeks were largely behind the rocketing food inflation.

Chancellor Jeremy Hunt said: “Falling inflation isn’t inevitable, so we need to stick to our plan to halve it this year.”

The data adds to the headache for the Bank of England ahead of its decision on interest rates on Thursday, with policymakers already facing a dilemma given recent turmoil in financial markets and fears of a banking crisis.

Some experts have been predicting the Bank would hold off from raising rates further due to the markets volatility, but the latest inflation data will likely complicate the decision.

The latest data showed that soaring prices of drinks in pubs and restaurants also drove inflation higher, coming after discounting in January and as the hospitality sector looks to offset sky high energy and staff bills.

Inflation overall in restaurants and cafes stood at 11.4 per cent last month, up from 9.4 per cent in January and the highest since December 1991.

ONS chief economist Grant Fitzner said: “Inflation ticked up in February mainly driven by rising alcohol prices in pubs and restaurants following discounting in January.

“Food and non-alcoholic drink prices rose to their highest rate in over 45 years with particular increases for some salad and vegetable items as high energy costs and bad weather across parts of Europe led to shortages and rationing.

“These were partially offset by falls in the cost of motor fuel, where the annual inflation rate has eased for seven consecutive months.”

February’s rise sees inflation climb back up having been steadily edging lower after peaking at an eye-watering 11.1 per cent in October last year, caused by soaring energy prices following Russia’s invasion of Ukraine.

It confirms that the pressure of the cost of living crisis is far from over for British households and businesses.

However, economists still believe stubborn inflation will begin to ease again this year.

The UK fiscal watchdog, the Office for Budget Responsibility (OBR) last week cut its forecasts for inflation, predicting CPI would end the year at around 2.9 per cent.

Motor fuel prices are falling – with the annual rate dropping to 4.6 per cent in February from 7.7 per cent in January.

The ONS said average petrol and diesel prices stood at 148.0p and 169.5p a litre respectively, in February 2023, compared with 147.6p and 151.7p a litre a year ago.

Last year’s painful energy bill hikes will also begin to drop out of the inflation calculation.

Alpesh Paleja, the CBI’s lead economist, said that “while inflation rose in February, the outlook for the months ahead is looking more benign”.

“But while we expect inflation to fall back over this year, the firmness in domestic price pressures is something that the Bank of England will be keeping a close eye on.

“And despite further falls over the coming months, this year will still be a high-inflation environment for both households and businesses.”

The latest data also showed rises in the CPI measure of inflation including housing costs (CPIH), up to 9.2 per cent in February from 8.8 per cent in January, while the Retail Prices Index (RPI) leaped to 13.8 per cent from 13.4 per cent in January.
