Core inflation measures the change in prices of goods and services by excluding food and energy costs, which are often volatile. This approach helps to focus on the more stable price changes, giving a clearer picture of the underlying trends in the economy. For example, much like how fluctuations in global energy prices can skew the broader inflation rate, core inflation provides a less erratic view by omitting these volatile categories, allowing for a more consistent analysis of price stability.
Core inflation example
Imagine grocery shopping where the cost of bread remains steady, while vegetable prices have spiked due to seasonal shortages, and gasoline costs have risen due to global events. General inflation would show an increase, potentially overstating price trends due to the temporary hikes in vegetables and gas. However, core inflation would reveal that prices for more consistent items, like bread, have stayed stable, providing a clearer view of underlying price trends without short-term volatility.
What is included in core inflation?
Core inflation includes prices for a broad range of goods and services excluding food and energy, which tend to fluctuate widely. This covers items that are more stable and regularly consumed, like:
- Clothing : Apparel prices, which change gradually over time.
- Housing : Costs related to rent and homeownership, offering insight into the stable cost of living.
- Medical Care : Health service costs that reflect ongoing demand and demographic changes.
- Education : School tuition fees and education expenses.
- Entertainment : Leisure and entertainment costs, adding a view into discretionary spending trends.
By excluding food and energy, core inflation provides a more stable and accurate reflection of price changes, making it essential for understanding long-term trends in the economy.
