TÜİK head defends agency’s inflation calculation

Erhan Çetinkaya, the head of the Turkish Statistical Institute (TÜİK), has dismissed criticism leveled at the authority over its inflation calculations.

Inflation is calculated in Türkiye the same way it is calculated in the world, Çetinkaya said in a press conference in the capital Ankara, adding that the difference between CPI (consumer price index) and PPI (producer price index) is not unique to Türkiye.

Some 300,000 of these prices consist of items purchased from markets and they are collected at the end of the month, Çetinkaya explained, noting that inflation is a calculation based on a weighted average of 600,000 prices.

The CPI is calculated in high conformity with Eurostat standards, said Çetinkaya.

When asked about the discrepancy in calculations between TÜİK and ENAG, an inflation research group, Çetinkaya noted that ENAG does not provide information on its website about its calculation method.
