Understanding UK GDP deflator, quarterly growth
Sequential quarterly inflationary movement across United Kingdom output is presented in this series as the quarter-on-quarter percentage change of the implicit GDP deflator. It tracks the change in the price of domestically produced output relative to the immediately preceding quarter. Unlike annualised or year-on-year metrics, this row offers a timely gauge of high-frequency price shifts in capital formation, public administration output, and export prices.
Data are seasonally adjusted, but quarterly deflator changes can be volatile due to shifting expenditure shares between volatile sectors such as energy extraction, transport equipment, or seasonal agricultural goods. Early readings carry wide confidence intervals because initial quarterly estimates of current price GDP and volume measures are balanced independently before supply-use tables reconcile them. Users should evaluate several consecutive quarters rather than overinterpreting a single quarterly swing.
Frequently asked questions
- What causes unexpected spikes in the quarter-on-quarter deflator?
- Sharp shifts in the expenditure mix between high-deflator and low-deflator sectors can create compositional spikes even if underlying transaction prices remain stable.
- Is this quarterly percentage change annualised?
- No, it represents the simple compound percentage movement between consecutive quarters without annualisation.
- How does government non-market output affect this quarterly rate?
- Changes in the estimated volume of public health or education delivery relative to government expenditure can generate volatility in the implicit government deflator component.
