Overview
- ONS identified an error in Vehicle Excise Duty data from the Department for Transport that overstated April’s CPI and RPI by 0.1 percentage points.
- Revised figures show the 12-month Consumer Prices Index rate at 3.4%, down from the initially reported 3.5%.
- In line with its policy on consumer prices, the ONS will not amend the published April statistics but will apply properly weighted tax inputs from May onwards.
- The overstatement affected inflation-linked agreements, including mobile phone contracts, and intensified scrutiny of the ONS’s data reliability.
- Bank of England Governor Andrew Bailey said the episode underscores the need for diverse data sources, prompting the bank to widen its range of indicators for rate decisions.
