TÜİK 2025 Inflation Data

The Consumer Price Index (CPI) is an economic indicator published by the Turkish Statistical Institute (TÜİK) that measures the average change in prices over time in a basket of goods and services purchased by consumers. The CPI is the primary statistical reference used to determine the direction and trend of inflation in Türkiye.

CPI data are shared with the public in the first week of each month, covering price changes from the previous month. The index includes prices of goods and services across numerous major expenditure categories such as food, housing, transportation, health, education, entertainment, and culture.

In Türkiye, the CPI is calculated using 2003 as the base year and is prepared annually using an updated consumption basket and weighted price data.

The CPI is published in two forms: monthly change rates (compared to the previous month) and annual change rates (compared to the same month of the previous year). Additionally, an annual change rate based on 12-month averages is also calculated and made available to users.

CPI data for 2025 are calculated and published using these same methods throughout the year.

During this period, the main groups influencing the overall index trend were food, education, restaurants and hotels, and transportation. TÜİK publishes detailed datasets each month, including index changes for both major expenditure groups and their subcategories, for public access.
