MKK Launches MDYS to Accelerate Account Opening Procedures for Non-Resident Institutional Investors

The Central Document Management System (MDYS), developed by MKK to accelerate and facilitate the account opening procedures of non-resident institutional investors in Türkiye’s capital markets, has been launched. Through the amendment made by the Capital Markets Board of Türkiye (CMB) to the MKK Regulation, published in the Official Gazette on 29 April 2025, MKK was assigned the task of enabling the necessary procedures to be carried out more swiftly in order to facilitate the account opening processes of non-resident institutional investors at authorized investment firms in Türkiye.

With MDYS, which has been developed by MKK and made available to our markets, non-resident institutional investors will be able to invest in Türkiye’s capital markets more quickly and easily. Through MDYS, non-resident beneficial owners will be able to submit their documents and account opening information securely, directly and more rapidly in digital form, instead of sending them to investment firms physically or through various channels such as email.

MDYS provides the following benefits to non-resident institutional investors:

• Faster and easier access to Türkiye’s capital markets through accelerated account opening procedures.
• The ability to initiate account opening procedures digitally and submit the related physical documents at a later stage.
• Faster and easier completion of various procedures, including applications for a Potential Tax Identification Number for Foreigners, by enabling the required documents to be shared with the relevant investment firms and stakeholders through a single centralized platform, subject to the investor’s approval.
