The best monthly measure of UK inflation for central bank purposes now available is likely the RPI excluding mortgage interest payments and council tax adjusted for the formula affect, which approximates a monthly UK HICP with an OOH(NA) component. It went from 3.1% in April and May to 3.0% in June. And it is still downward biased, as it excludes stamp duty, which should have been added to the RPI measure. Alan Clarke spoke of UK inflation exceeding the 3% upper bound later this year. Properly measured, UK inflation has been above 3% from April forward.
