What Is Core Inflation? Definition, Importance, and Its Application in Türkiye
In the world of economics, the term “core inflation” frequently emerges, especially when discussing central bank decisions and inflation targeting. Unlike headline inflation, core inflation aims to provide a more stable and reliable measure of underlying price movements by excluding volatile components. So, what exactly is core inflation, why does it matter, and how is it calculated in Türkiye? This comprehensive article answers all these questions in detail.
What Is Core Inflation?
Core inflation is a measure that excludes temporary and seasonal effects from overall inflation, aiming to reflect the long-term trend in price changes. It typically omits categories like energy, food, alcohol, and tobacco—items whose prices can fluctuate sharply due to external factors such as weather, international commodity markets, or geopolitical tensions.
By focusing on more stable goods and services, core inflation provides economists and policymakers with a clearer view of persistent inflationary pressures.
Core Inflation vs. Headline Inflation
| Criterion | Headline Inflation | Core Inflation |
|---|---|---|
| Definition | Includes all items in the CPI basket | Excludes volatile items like energy and food |
| Influence | Affected by short-term shocks | Reflects long-term trends |
| Usage | Used in public and media discussions | Used in monetary policy decisions |
For these reasons, central banks tend to rely more heavily on core inflation when setting interest rates and designing monetary policy.
How Is Core Inflation Calculated in Türkiye?
In Türkiye, the Turkish Statistical Institute (TÜİK) calculates core inflation using specific sub-indices known as “Special CPI Aggregates.” These are categorized with labels such as B, C, D, and E, each excluding different components from the main CPI.
Most Common Core Inflation Measures in Türkiye:
- B Index: Excludes energy, unprocessed food, alcoholic beverages, tobacco, and gold.
- C Index: Excludes energy, food and non-alcoholic beverages, alcoholic beverages, tobacco, gold, and administered prices.
These indicators are particularly significant for the Central Bank of the Republic of Türkiye (CBRT) in shaping interest rate decisions.
Why Is Core Inflation Important?
- Better Policy Decisions: By filtering out short-term shocks, policymakers can make more informed and stable decisions.
- Inflation Targeting: To reach inflation targets, understanding long-term price trends is essential, and core inflation provides this insight.
- Credibility and Transparency: Investors and markets prefer reliable indicators when forecasting economic performance.
- Structural Understanding: Core inflation reveals the underlying dynamics driving price changes in the economy.
Advantages and Disadvantages of Core Inflation
Advantages:
- Free from temporary and seasonal distortions
- Better suited for guiding monetary policy
- Highlights structural trends in the economy
Disadvantages:
- May be complex for the general public to understand
- Doesn’t fully reflect the inflation experienced by households
- Definitions and excluded items vary by country
Core Inflation Trends in Türkiye
In recent years, core inflation in Türkiye has often trailed headline inflation. Between 2021 and 2024, fluctuations in exchange rates, rising energy prices, and volatile food costs caused significant increases in headline inflation, while core inflation showed a more moderate trajectory.
The C Index, in particular, has become a primary reference for the CBRT when evaluating long-term inflationary pressures and adjusting policy rates accordingly.

Core Inflation as an Economic Compass
Core inflation is not merely a technical term—it’s a crucial tool for gauging economic health and designing effective monetary policy. In emerging economies like Türkiye, where external shocks are common, core inflation provides a more accurate and consistent signal for long-term price dynamics.
Whether you’re an investor, policy analyst, or simply a curious observer of economic trends, understanding core inflation is essential to interpreting where an economy is headed and how central banks will respond.
