FX.co ★ UK RPI Inflation Doubles Month‑on‑Month in July 2026

The United Kingdom’s Retail Price Index (RPI) inflation accelerated in July 2026, with the month‑on‑month rate rising to 0.6%, up from 0.3% in June 2026. The latest figures, updated on 19 August 2026, show that price pressures tracked by the RPI have effectively doubled over the month.

On a month‑over‑month basis, July’s “actual” reading compares the change in prices from July to June, whereas the “previous” reading of 0.3% reflected the change from June to May. The move from 0.3% to 0.6% indicates a strengthening pace of price increases heading into the second half of 2026, and will be closely watched by market participants assessing the trajectory of UK inflation.
