Core inflation
3 key takeaways
Copy link to section- Core inflation excludes volatile items like food and energy prices, offering a more stable measure of long-term inflation trends.
- It helps central banks and policymakers in setting monetary policy by focusing on the underlying inflationary pressures in the economy.
- Core inflation is considered more reliable for long-term economic planning and analysis than headline inflation, which includes all items.
What is core inflation?
Copy link to sectionCore inflation is an adjusted measure of inflation that removes the effects of certain volatile components, typically food and energy prices, from the overall consumer price index (CPI). This adjustment provides a clearer view of the persistent, underlying inflation trends without the short-term fluctuations caused by these volatile items.
Key components excluded in core inflation:
Copy link to section- Food Prices: Often subject to seasonal changes, weather conditions, and supply chain disruptions.
- Energy Prices: Includes items like gasoline and heating oil, which can be highly volatile due to geopolitical events, natural disasters, and other factors.
Example:
Copy link to sectionIf the overall CPI indicates a 4% inflation rate, but food and energy prices have spiked due to a temporary disruption, core inflation might show a lower rate, such as 2%, reflecting the more stable price changes excluding these volatile items.
