Turkey's economic confidence index increased 0.7% from 100.6 in August to 101.3 in September 2026, TÜİK reported on 29 September. The reading stayed above the neutral level of 100 for a second month, but the components do not point in one direction: consumers and retailers became more confident, manufacturing edged up, services were flat and construction weakened slightly.
What moved the composite index
Consumer confidence rose 1.2% to 91.9, seasonally adjusted real-sector confidence increased from 102.4 to 102.5, and retail confidence gained 1.1% to 111.3. Services held at 111.9. Construction slipped 0.2% to 83.0. The composite therefore improved, but the household and construction readings remain below 100 even as other business components are above it.
Above 100 is a survey signal, not a growth rate
TÜİK's index runs from 0 to 200. A value above 100 means optimistic responses outweigh pessimistic ones in the combined survey; it does not mean the economy, sales, wages or property prices grew by 1.3%. The 0.7% monthly change describes the index itself. GDP, inflation, turnover and employment are measured in separate releases.
The construction gap matters for property investors
Construction confidence at 83.0 is the clearest weak point in the September mix. It is a national sentiment indicator, not evidence that every developer is under stress. Buyers should still verify land title, zoning and permits, construction progress, financing, contractor obligations, presales and delivery history. A stronger composite index cannot validate an individual project.
What international businesses should take from it
Retail and service readings above 100 suggest a more supportive operating mood, but they do not replace company-level evidence. An investor should compare audited revenue, margins, inventories, lease exposure, borrowing costs and foreign-currency liabilities. For tourism and consumer businesses, seasonality and the geographic mix of customers can matter more than the national average.
A balanced reading of September
The release is mildly positive because the headline remained above 100 and improved from August. It is not a broad all-clear: household sentiment is still below neutral, construction remains cautious and one monthly move is not a trend. The most useful conclusion is that confidence is resilient but uneven across the Turkish economy.
