2026 TÜİK Inflation Data

Consumer Price Index (CPI) is a key economic indicator published by the Turkish Statistical Institute (TÜİK) that measures average price changes over time in a basket of goods and services purchased by consumers. The CPI serves as the primary reference statistic for determining the direction and trend of inflation in Türkiye.

CPI data released in the first week of each month cover price changes from the previous month. The index includes prices of goods and services across numerous main expenditure categories such as food, housing, transportation, health, education, entertainment and culture.

In Türkiye the CPI was historically calculated using the base year 2003=100 but as of 2026 it has been updated to the base year 2025=100 in accordance with European Commission standards.

The index is prepared annually using updated consumption baskets 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, the annual change rate based on a twelve-month average is also calculated and made available to users.

According to TÜİK’s definition, inflation is “the continuous loss of purchasing power of money due to a sustained and significant rise in the general level of prices.”
