Central Document Management System

Central Document Management System (MDYS), developed to accelerate and facilitate the account opening procedures of foreign institutional/resident investors in our capital markets, has been launched. With the amendment to the MKK Regulation by the Capital Markets Board (CMB), published in the Official Gazette on April 29, 2025, MKK was tasked with executing the necessary procedures more swiftly to facilitate the account opening processes of foreign investors at authorized investment firms in our country.

With MDYS, which we have fully developed and put into the service of our markets, foreign investments into our capital markets will be realized much faster and with greater ease. Through MDYS, foreign beneficial owners will be able to securely, directly, and more rapidly transmit their paperwork and necessary account opening documents digitally, which they previously used to send to investment firms physically or through various channels such as email.

MDYS provides the following benefits to foreign resident investors:

• Faster and Easier Investment: Enables faster and more convenient investment in our capital markets due to the accelerated account opening process.
• Delayed Physical Document Submission: Allows physical documents related to the account opening procedures—which are initiated digitally—to be sent at a later date.
• Centralized Data Sharing & Efficiency: By granting approval to share the required documents with relevant investment firms and stakeholders through a single centralized hub, numerous procedures, including the Application for a Potential Tax Identification Number for Foreigners, can be carried out much faster and with greater ease.
