Iran war yet to push up UK grocery prices, says Worldpanel

By James Davey

LONDON, April 28 (Reuters) - ‌British grocery inflation ​eased ​to 3.8% in the four weeks to April 19 from 4.3% in the previous period, data from Worldpanel by Numerator showed on Tuesday, ‌indicating that the war with Iran has yet to feed through ⁠to supermarket prices.

The data showed UK grocery sales increased 0.9% in the four-week period year-on-year. With ‌shoppers increasingly seeking deals, spending on ‌promoted items rose 7.8%.

"Already feeling the squeeze at the petrol pump, shoppers are responding by turning to special offers in growing numbers when buying groceries," Fraser McKevitt, head of ​retail and consumer insight at Worldpanel, said.

The Worldpanel data give the most up-to-date snapshot of UK consumer behaviour and provide an early indication of pricing ⁠pressures in April ahead of official UK data on May 20.

MEDICINES, MEAT AND FISH PRICES RISING FASTEST

It said ​prices were rising fastest in markets such as medicines and treatments and fresh unprocessed meat and fish, and falling fastest in butter ​and spreads, sugar confectionery and household paper.

It said ‌the easing of grocery inflation indicated "that the impact of the conflict in the Middle East has not yet filtered through to ⁠supermarket shelves in Britain."

Tesco, Britain's biggest food retailer, said earlier this month it had not yet seen any meaningful inflation in grocery prices due to the conflict and "did not recognise" ⁠a Food and Drink Federation warning that food prices will be rising by almost 10% by ​December.

Separate data on Tuesday from the British Retail Consortium showed overall shop price inflation decreased to 1.0% in April, helped by Easter discounts. Britain's official rate of headline inflation rose to ‌3.3% in March.

Worldpanel said that over the 12 weeks to April 19, Tesco and Sainsbury's continued to win market share.

Discounter Lidl ‌GB remained the fastest growing bricks-and-mortar grocer, while online supermarket Ocado remained the fastest growing ⁠overall. Asda continued to lose ‌share.
