TÜİK announced: Monthly increase in construction costs is 1.81 percent

Turkey’s construction cost index rose 1.81% month-on-month in September 2026, according to data from the Turkish Statistical Institute (TÜİK). Annual cost increases for non-building structures reached 35.66%, with material price rises standing out as a key driver. The data matters because sustained construction cost inflation feeds through to contractor margins, public infrastructure budgets and ultimately housing and rent prices. Investors will watch whether material costs continue to outpace the headline index in coming months and whether the monthly pace moderates.
