The announcement date of the September inflation data by the Turkish Statistical Institute (TÜİK) has started to be questioned by homeowners and renters. Inflation data will be announced in the first week of each month. So, when will inflation data be released, and what is the September inflation expectation? The September inflation data to be announced in October has become a subject of curiosity. Before the determination of the September rent increase based on the twelve-month CPI data average, citizens are researching economists’ expectations. The date on which the September inflation data will be announced by the Turkish Statistical Institute (TÜİK) has been determined. Accordingly, the September inflation data will be announced on Thursday, October 3, 2024, at 10.00. According to the Central Bank of the Republic of Turkey (CBRT) Market Participants Survey, the year-end increase expectation in the Consumer Price Index (CPI) fell to 43.14%. The CBRT published the September Market Participants Survey conducted with 64 participants consisting of real and financial sector representatives and professionals. Accordingly, the September CPI increase expectation, which was 2.22% last month, did not change during this survey period. The year-end CPI increase expectation, on the other hand, decreased from 43.31% to 43.14%. The expectation for an increase in the CPI for twelve months ahead is 28.71%.
