History of Central Securities Depositories in Türkiye

The ISE Settlement and Custody, Inc., which was established by the ISE in 1992, was the authorized central settlement and depository institution conducting settlement of transactions in cash and securities on the ISE markets. In Türkiye, until 1995, Takasbank physically held stocks of listed companies in its vaults on a participant based immobilized system. After the financial crisis in 1994, as a result of the bankruptcy of some financial intermediaries, the ISE Settlement and Custody, Inc. was entrusted with the establishment of an investor (beneficiary owner) based immobilized system with respect to the Capital Markets Board (CMB) decree on 15 December 1994. The ISE Settlement and Custody, Inc. changed its name to the ISE Settlement and Custody Bank, Inc. (Takasbank) by receiving an investment banking license in 1997. During this period, stock certificates were continued to be physically issued and new certificates were printed for capital increases. However, publicly traded stocks of the ISE listed companies were immobilized at Takasbank first on a participant then on an investor basis. Therefore, the traditional valuable papers law and the physical system still existed legally for stocks and Takasbank continued its tasks accordingly until 28 November 2005.​
