Türkiye’s September 2026 economic calendar: GDP, inflation and the CBRT rate decision
Turkish markets face three major releases in less than two weeks: second-quarter GDP, August inflation and the CBRT rate decision. Dates are verified from official calendars; unreleased outcomes are not presented as facts.

Quick answer: what is released, and when?
Türkiye’s second-quarter 2026 GDP data are scheduled for Monday, August 31 at 10:00 TRT. August CPI and domestic producer-price data follow on Thursday, September 3 at 10:00 TRT. The CBRT’s Monetary Policy Committee meets on Thursday, September 10, with the rate decision and accompanying statement released at 14:00 TRT.
August 31: four GDP details beyond the headline
The year-on-year GDP rate is only the starting point. Seasonally and calendar-adjusted quarter-on-quarter growth shows recent momentum; household consumption tracks domestic demand; gross fixed capital formation shows investment; and net exports reveal the external contribution. Divergence across industry, construction, finance and services may be more informative for Turkish corporate revenues than the headline alone.
September 3: which inflation lines matter?
Consumer prices rose 1.78% month on month and 31.75% year on year in July 2026. For August, investors should read monthly CPI, core measures, services inflation, food and energy together. Whether momentum persists across several months matters more for pricing behavior and expectations than one isolated upside or downside surprise.
September 10: what time is the CBRT decision?
The CBRT’s official 2026 schedule places the meeting on September 10, and the Bank’s standard publication time for rate decisions is 14:00 TRT. The Committee kept the one-week repo rate at 37% on July 23. In September, language on underlying inflation, domestic demand, energy, credit and liquidity management may matter alongside the rate itself.
Possible channels for equities, the lira, deposits and gold
Market reactions are often driven by the gap between the release and expectations. The composition of growth can affect banks, industrials and consumer companies differently. Inflation and CBRT communication have a more direct connection to bond yields, deposit and loan pricing, and the lira. Turkish gram gold reflects both international gold and USD/TRY, so domestic data and global dollar-rate moves can pull in different directions.
Why the three releases should be read together
GDP describes realized activity in the previous quarter, inflation provides the latest monthly price signal, and the CBRT decision shows the policy response. Strong activity with high inflation creates a different trade-off from weak activity with slowing inflation. Consistency across the three releases—and changes in the policy statement—therefore matters more than any single headline.
