Currency data
Daily ECB reference rates are fetched through the free Frankfurter v2 API, with the ECB provider explicitly selected. These are reference observations, not executable quotes. Cross-rates are calculated from the same USD-based observations. The chart labels the last observation date; an unavailable source produces an unavailable state, never an invented price.
Economic data
World Bank World Development Indicators provide annual inflation, real GDP growth, unemployment and current-dollar GDP. The observation year and source update date are shown separately. Annual CPI is not the latest monthly Turkish CPI figure. Missing observations are omitted without interpolation. World Bank datasets carry CC BY 4.0 or source-specific terms.
News and politics
Our automatic feed contains official Central Bank announcements and links to the originals. It is not an exhaustive newswire. Our source directory links to company disclosures, official policy records and independent reporting. Official claims reflect the issuing institution’s position; they do not become independent conclusions merely because we link to them.
Calendar and company profiles
The calendar is a reviewed schedule from CBRT, not a live prediction engine. Dates may change. Company profiles are a curated directory of 20 businesses, not an exhaustive exchange listing or an investment recommendation. Verify current company details on KAP and the issuer’s website.
Equity prices
Exchange data redistribution requires appropriate rights. We link to source charts instead of presenting unlicensed or fabricated BIST prices. Delay, availability and terms are determined by the external provider.
Editorial and update standards
Original insights carry review dates and distinguish examples from actual observations. The pack is the September 2026 edition. The weekly newsletter is an automated, source-labelled digest with a rotating educational note; it does not claim to cover every political development.
