Key drivers
- Energy: the BoE's 30 April 2026 statement says inflation 'has risen to 3.3%... higher than we predicted in February, before the start of the war; likely higher later this year' — an oil/energy shock is pushing prices up into mid-2026.
- Owner occupiers' housing costs (the CPIH-specific component) have been a persistent upward wedge keeping CPIH above CPI.
- Base effects: the large April-2025 monthly increase has now annualised out; the May-2025 monthly change was more moderate, so the May-2026 YoY rate is less mechanically suppressed than April's.
- Core CPIH disinflation (2.8% in April) partly offsets energy-led headline pressure.

- rule
- Resolves to the first-published ONS CPIH (CPI including owner occupiers' housing costs) 12-month inflation rate for May 2026 in the Consumer price inflation, UK bulletin, headline table, rounded to one decimal place as published. Later revisions do not change the resolved value. This forecast targets CPIH specifically, distinct from the all-items CPI measure.
