UK grocery inflation remained at 4.3% in the four weeks leading up to March 22, according to researcher Worldpanel by Numerator. The increase is expected to increase further due to an expected rise in food prices due to the Iran war. The data provides an early indication of inflation pressures in March ahead of official UK data on April 22. Each additional 1% on the rate of grocery inflation could add over 50 pounds ($100) to the average household's annual bill.
