What is Bankacılık Düzenleme ve Denetleme Kurumu?
The Bankacılık Düzenleme ve Denetleme Kurumu (BDDK), the Banking Regulation and Supervision Agency of Türkiye, is the country’s banking regulator. It licenses and supervises banks and, under Law No. 6361, financial leasing, factoring and financing companies. Its current legal basis is Banking Law No. 5411 (2005), whose Article 82 establishes it as an autonomous public legal entity headquartered in Istanbul; the agency was originally created under the now-repealed Banks Law No. 4389 of 18 June 1999. For founders building a business that takes deposits or extends regulated credit, BDDK is typically the most consequential regulatory counterpart.
Not BDDK: payments and e-money. Since 1 January 2020, payment institutions and e-money institutions are licensed and supervised by the Central Bank of the Republic of Türkiye (TCMB). Law No. 7192 (Official Gazette 22 November 2019, No. 30956) moved these powers from BDDK to TCMB by amending Law No. 6493. Fintechs offering payment accounts, money transfers, acquiring, e-money, payment initiation or account information services therefore deal with TCMB, not BDDK.
BDDK’s licensing perimeter covers: (i) Banks: deposit banks, participation banks, and development and investment banks, including digital banks; (ii) Asset Management Companies (varlık yönetim şirketleri): entities acquiring and resolving non-performing loans; and (iii) Financial Leasing, Factoring, Financing and Savings Finance Companies under Law No. 6361: non-bank credit providers in specific sub-categories.
Major frameworks BDDK applies include Law No. 5411 (Banking Law), the foundational framework for the banking sector; Law No. 6361 on financial leasing, factoring, financing and savings finance companies; and a body of regulations and communiqués covering IT systems and electronic banking, operational risk, customer protection and capital adequacy, applied alongside MASAK’s AML rules.
BDDK supervisory practice spans several mechanisms: (i) licensing and authorization: multi-month application processes with detailed regulatory review of business plans, capital, IT infrastructure, governance, key personnel; (ii) ongoing reporting: frequent operational, financial, and risk reporting through standardized formats; (iii) on-site inspections: regular and event-triggered inspections by BDDK supervisors; (iv) thematic supervision: focused reviews of specific risk areas (cybersecurity, operational resilience, AML, customer protection); and (v) enforcement: administrative penalties (substantial fines, license restrictions/revocation), criminal referrals for serious violations, public censure.
For founders of banking, lending, leasing or factoring businesses, BDDK engagement is foundational and intensive: licensing-pathway analysis (which license tier fits the business model, timeline and capital implications), application-package preparation (business plan, governance documentation, operational-risk framework, IT specifications, AML/KYC programs, capital and shareholder documentation), pre-launch operational-readiness validation, ongoing supervisory-relationship management, and enforcement-response coordination when issues arise.
