UK grocey inflation eased to 2.1% (Prev. 2.6%) in the four week to August 9th, Worldpanel says

Worldpanel/Kantar grocery inflation is a private-sector proxy read on UK food prices, not the official series: it has historically been used as an early steer on the food component of CPI rather than as a standalone market mover, with headline and gilt reaction reserved for the ONS print itself. The distinction worth drawing is between falling food inflation and falling overall services inflation: UK rate pricing through past easing cycles has been driven far more by the latter, since food is a smaller and more volatile share of the consumption basket, so a soft grocery read rarely shifts the policy path on its own. What this kind of print does inform is the pass-through question: periods of elevated input and energy costs have historically shown up first at the shelf edge and unwound with a lag, and survey reads like this have tended to lead the official food CPI component in both directions. The follow-ons are the next official CPI release, where the food component is checked against this read, and any commentary from retailers or the central bank on whether goods disinflation is broadening or simply reflecting base effects and promotional intensity. As a softening private survey, the signal is directional confirmation rather than new information for the rates market.
