The Capital Markets Board of Turkey (Sermaye Piyasası Kurulu - SPK) is the financial regulatory and supervisory authority responsible for regulating the securities and capital markets of Turkey. Its mandate is to ensure the fair, transparent, and efficient operation of the securities markets, protect investor rights, supervise public companies and brokerage firms, and prevent market abuse. Established in 1981 under Capital Markets Law No. 2499, the Board began formal operations in 1982 to modernize Turkey's financial system and paved the way for the creation of the Istanbul Stock Exchange (now Borsa Istanbul).
