Sayfa 1/ 15 ON A NEW AND COMPLEX REGULATION DIRECTLY RELATING TO BANKS: What Does the Regulation on Sharing of Secret Information Bring? Dr. Murat Volkan Dülger * To determine the scope, form, procedures and principles regarding the sharing and transfer of information in the nature of bank secrets and customer secrets the “Regulation on Sharing of Confidential Information” (“Regulation”) was published in the Official Gazette dated 4 June 2021 and numbered 31501 to enter into force on 1 January 2022. First of all, what does this mean? Accordingly, everyone within the scope of the Regulation must comply with the provisions of this Regulation as of January 1, 2022! I will explain below who needs to be compatible with what. On the other hand, in terms of the close relationship of the issue with the personal data protection legislation, it is extremely important and necessary to consider it together with the data protection legislation in order to determine what obligations the Regulation imposes on whom. Before that, it is useful to remind a change made a short time ago in order to better understand the Regulation. Because, with the 10th article of the “Law on the Amendment of the Banking Law and Certain Laws” numbered 7222, which was published in the Official Gazette dated February 25, 2020 and numbered 31060, some amendments were made to the Banking Law numbered 5411. However, these changes have been the subject of criticism, especially for their lack of clarity. It is pleasing that the subject has been handled with a Regulation this time, in that it includes more detailed explanations on personal data processing activities carried out in the banking sector. However, it should be noted that the Regulation brings about many new question marks. Finally, it should be noted that the Regulation was published by the Banking Regulation and Supervision Agency (“BDDK”), and the BDDK is the body responsible for executing the provisions. I will mention some confusions in this respect later on. In this article, I will try to explain who should do what as a result of the said Regulation. Where it is not clear what to do, I will state my own opinion and suggestion. * Assoc. Prof. of Criminal Law and IT Law.
