Istanbul's inflation rate continued its upward trajectory, reaching 40.84% in October 2025, up from 40.7% the previous month, with the city's consumer price index (CPI) recording a monthly increase of 3.31%, according to a report by the Istanbul Chamber of Commerce (ICOC) on Saturday.
The figures came ahead of the release of nationwide data by the Turkish Statistical Institute (TurkStat) on Monday, Nov. 3, indicating that broader inflationary trends across the country may align closely with the upward pressure observed in Europe's largest city.
Several categories experienced notable price hikes in Istanbul, with clothing and footwear seeing the most significant rise. The sector recorded a sharp increase of 17.26%, driven by the introduction of winter-season products. Other sectors also saw price increases, including food and non-alcoholic beverages, up 4.05%, and restaurants and hotels, which saw an increase of 3.97%.
Communication services also experienced a notable price surge of 5.42%, while housing, furniture, and transportation costs also rose, albeit at lower rates.
The rise in food prices was partly attributed to the onset of the winter season, with certain products experiencing seasonal cost hikes. Similarly, the hospitality and restaurant sectors saw price adjustments linked to broader market conditions.
In September, Türkiye recorded a 3.23% increase in consumer prices compared to the previous month, well above market expectations.
