Türkiye Economy & Business News: September 2026September brought an interest rate decision, changes to liquidity tools, a government medium-term programme and releases on growth, trade, prices and the budget. There were also company listings, an airport expansion that entered service and a temporary market trading measure. This review covers fourteen documented economic developments.
Coverage: 1–30 September 2026. Last reviewed: 8 October 2026. August and second-quarter figures appear according to the September publication date of the news or analysis; each entry identifies its reference period. This is a broad selection, rather than an exhaustive record of every local economic story. The two archive photographs illustrate the report and do not depict September events.

Intetra Technology begins trading under INTET1 September 2026 | Trading starts 1 September; subscription 26–27 August
Intetra Technology and Information Services shares began trading on Borsa Istanbul's Star Market on 1 September under the ticker INTET, following the public offering subscription on 26–27 August. The exchange described its business as combining software, hardware, data, payment and operational technologies for transport and mobility infrastructure. The completed event was the listing and start of trading. Statements about using offering proceeds for investments and new projects describe announced intentions and do not establish that those projects were completed. The listing adds a technology company to the month's financing news; assessing its financial results or share performance requires further disclosures, rather than the opening ceremony alone.

Preliminary August trade: exports of USD 23.467 billion3 September 2026 | August and January–August
The Ministry of Trade announced on 3 September that August exports totalled USD 23.467 billion, up 8.1% from August 2025, while imports reached USD 28.706 billion, up 10.5%. Total trade was USD 52.173 billion. January–August exports were USD 185.006 billion and imports USD 250.791 billion. These preliminary ministry figures concern trade in goods during the period preceding the publication month. Annual comparisons show changes in monetary values; on their own, they do not establish changes in volumes, margins or each commodity's contribution. When following a longer series, retain the same source and its preliminary status, so that subsequent revisions are not presented as a separate new economic event.

Second-quarter analysis: real GDP grows by 2.3% annually3 September 2026 | April–June; SBB analysis published 3 September
The Presidency of Strategy and Budget (SBB) published its second-quarter analysis on 3 September. Real gross domestic product (GDP) grew by 2.3% compared with the same period of 2025, and by 1.1% from the first quarter after seasonal and calendar adjustment. Agriculture grew by 13.3% annually, industry by 2.4%, and services including construction by 1.6%. Private consumption increased by 3.5%, government consumption fell by 1.8%, and net exports contributed 0.6 percentage points to growth. The measured period is April–June, rather than the third quarter. Real growth differs from a nominal increase in local currency, while a component's contribution to growth, measured in percentage points, differs from that component's own growth rate.

August consumer inflation reaches 31.51% annually4 September 2026 | SBB analysis of August consumer prices
SBB's August price analysis reported a monthly consumer price index (CPI) increase of 1.84% and annual inflation of 31.51%, down 0.24 percentage points from July. Transport prices rose by 4.82% during the month, contributing 0.82 percentage points to monthly inflation, while clothing and footwear prices fell by 3.54%. These figures describe the August basket. A lower annual inflation rate does not mean that every price fell, and a subcategory's percentage change differs from its weighted contribution to the overall index.
5.
Domestic producer prices rise by 2.57% in August4 September 2026 | August domestic producer prices
The same analysis reported that the domestic producer price index (D-PPI) rose by 2.57% monthly and 27.95% annually in August. Manufacturing prices increased by 2.35% monthly, while energy prices within the main industrial groups rose by 6.99%. The series helps track prices at the production stage and should be read alongside consumer data with their different weights and coverage in mind. The headline rate alone cannot identify an individual factory's costs or the share passed through to retail prices: contracts, inputs, inventories and pricing dates vary between businesses.

The Medium-Term Programme for 2027–2029 is published6 September 2026 | Planning document: 2026 estimates and 2027–2029 targets
SBB announced the Medium-Term Programme for 2027–2029 on 6 September. It estimates growth in 2026 at 3.3%, followed by a target path of 4.2% in 2027, 4.6% in 2028 and 5.0% in 2029. It also gives estimated year-end inflation of 28.4% for 2026, followed by 21.0%, 13.5% and 9.0% for 2027, 2028 and 2029 respectively. These are planning estimates and targets published in September, rather than completed results for those years. They remain separate from the central bank forecast issued in August, because the two documents have different authors, dates and assumptions. Publication of the programme is a completed event; progress towards its targets must be assessed through subsequent data and implementation.

Airports handle 167.6 million passenger movements through August9 September 2026 | August and January–August
The General Directorate of State Airports Authority (DHMİ) reported on 9 September that August passenger traffic reached 28,794,764, up 4.1% from August 2025. January–August traffic totalled 167,552,966 passenger movements, up 2.8%, including direct transit. Istanbul Airport handled 8,580,441 passenger movements in August. The report concerns airport operations during the peak travel season; these counts are not the number of unique tourists, since a person may pass through several airports or travel repeatedly. Traffic volumes also differ from revenue and expenditure. The figures should therefore be used as an air transport measure within their stated definition. Assessing their impact on tourism or operators' profits requires separate sources and measurements.

Central bank keeps the policy rate at 37%10 September 2026 | Monetary Policy Committee decision of 10 September
On 10 September, the Central Bank of the Republic of Türkiye (CBRT) kept its one-week repo rate at 37%, its overnight lending rate at 40%, and its overnight borrowing rate at 35.5%. The statement described a slowing underlying inflation trend despite monthly fluctuations, weak domestic demand and continuing upside risks from high energy prices. The decision sets the rates for the specific central bank instruments named in the statement; commercial loans and deposits do not all carry those same rates. The bank reiterated that decisions would be taken meeting by meeting, according to inflation developments and expectations. The hold is therefore recorded as an event on the meeting date, without adding an unannounced future cut. Its transmission to lending should be assessed using subsequent interest rate and credit data.

August budget records a surplus of TRY 12.852 billion15 September 2026 | August and January–August
Central government budget results updated on 15 September show August expenditure of TRY 1,642,058 million and revenue of TRY 1,654,910 million, producing the officially reported surplus of TRY 12,852 million, or TRY 12.852 billion. January–August recorded a cumulative deficit of TRY 1,308,088 million. This illustrates the difference between a single month and the year to date: August's surplus does not erase the accumulated deficit. The figures refer specifically to the central government budget and retain the table's unit of millions of Turkish lira. They should not be substituted for the Treasury cash balance or the wider public sector deficit, since each has its own accounting boundaries and source.

Central bank reviews lira liquidity facilities17 September 2026 | Measures announced on 17 September
The CBRT announced a review of liquidity facilities on 17 September in light of financial market developments. Measures included increasing funding through weekly repo auctions with liquidity conditions taken into account, updating banks' borrowing limits in the central bank's interbank money market, and reducing collateral haircuts in its markets. The statement gave neither a fixed amount of additional funding nor a single numerical borrowing limit, so no such figures are attributed to it here. These are liquidity management tools and should be read separately from the interest rate hold on 10 September. An announcement that facilities will be made available under stated conditions does not itself establish that every bank used them or that a particular pressure was fully resolved.

Net Global begins trading under NETGL17 September 2026 | Trading starts 17 September; subscription 9–11 September
Net Global shares began trading on the Star Market on 17 September under NETGL, following the public offering subscription on 9–11 September. The exchange described the company's high-density plastic pipe business and investments in renewable energy, modern agriculture and a railway wagon factory. The established event is entry into exchange trading; the stage, production timetable and cost of each investment require their own disclosures. Merely mentioning a sector in a company profile does not demonstrate that a new facility opened in September. The listing provides a way to follow a business with several activities in industrial and financing news, without automatically linking its opening ceremony to sector-wide production growth or unpublished financial results.

Istanbul Airport's fourth main runway opens18 September 2026 | Opening and entry into service on 18 September
DHMİ documented the opening of Istanbul Airport's fourth main runway and its first take-off on 18 September. The runway is 2,820 metres long and 45 metres wide, with an announced investment value of EUR 890 million. Including reserve runways, the airport's total rose to six. The fourth main runway and six runways in total describe different classifications, rather than conflicting counts. Here there is evidence of entry into service, so the event is reported as an operational development completed during the month. The announced benefits of shorter waiting times and lower fuel use remain expectations, rather than measurements of results after the opening. They can subsequently be evaluated using comparable operational data.

Uptick rule introduced for eligible short sales22 September 2026 | Effective 22 September until further notice
Borsa Istanbul announced the temporary application of the uptick rule to eligible short sales in BIST 50 shares, effective from 22 September until further notice. Under the announcement, a short sale must be executed above the last transaction price, or at that last price if it was higher than the preceding price. The scope concerns eligible shares and a particular transaction type; it is not a general ban on all exchange trading. This entry summarises the market announcement at its publication date, without extending its conditions to other securities or determining the validity of any individual order. As no fixed end date was given, the wording remains until further notice.

Ankara family food expenditure estimated at TRY 37,800.9230 September 2026 | September research on a family of four in Ankara
TÜRK-İŞ published its estimate on 30 September of monthly food expenditure for a family of four in Ankara: TRY 37,800.92. Total basic needs were estimated at TRY 123,130.00. The food basket's cost rose by 1.10% monthly and 35.14% over twelve months. The latter measures the research basket's price change and does not replace official national inflation. Similarly, the basic-needs estimate describes a family's living costs under a specific method; it is neither a statutory wage nor the proportion of the population in poverty. The report adds a household perspective to the month's consumer price news. The two series should retain their identities when compared, rather than having their differences automatically treated as errors.
How should these stories be read together?A planning document, a monetary decision and observed data serve different purposes. An estimate describes what an institution expects when preparing it; a decision establishes an instrument or measure from its effective date; and statistics measure a period that has ended. Comparisons should preserve these roles, without turning a target into a result or an announced facility into completed use.
The month, the quarter and the year to date answer different questions. A month's result may improve without changing the sign of the cumulative balance. Percentages also differ from percentage points: the former measure a rate of change, while the latter express a difference between rates or a contribution to an overall rate.
Operational developments need evidence that operations have begun. Infrastructure stories have announcement, financing, construction and opening stages. A report of entry into service establishes that final stage within its scope; projects mentioned in a newly listed company's profile do not establish completion of every facility. The report therefore retains the appropriate source verbs: announced, expected, began trading or opened.
