Banking and Finance Law in Turkey

Atty. Av. Serkan KARA, Serka Law Firm

Banking and finance activity in Turkey is governed primarily by the Banking Law No. 5411, which makes the Banking Regulation and Supervision Agency (BRSA/BDDK) the licensing and supervisory authority for banks, while the Capital Markets Law No. 6362 places securities, public offerings, and fund management under the Capital Markets Board (CMB/SPK). For a foreign investor, lender, or financial institution, the practical question is which regulator governs the activity, what license it requires, and how cross-border capital moves in and out under that framework.

Licensing questions, cross-border lending and correspondence with the regulator are handled by Serka Law Firm for foreign institutions and investors; write on WhatsApp at +90 530 127 59 35 or to info@serkalaw.com.

What law governs banking and finance in Turkey?

Banking is governed by the Banking Law No. 5411, administered by the BRSA (BDDK), which grants and revokes banking licenses, approves changes of control, sets capital and risk requirements, and imposes sanctions. Securities, public offerings, and collective investment fall under the Capital Markets Law No. 6362, administered by the CMB (SPK). Payment and electronic-money services are governed by the Payment and Securities Settlement Systems Law No. 6493. Anti-money-laundering supervision sits with MASAK, and personal-data handling with the Personal Data Protection Law No. 6698 (KVKK).

These statutes form a layered framework rather than a single code. Most financial activity touches more than one regulator at once, so the first step in any matter is mapping the activity to the correct governing law and supervisory body before structuring the transaction or applying for a license.

The principal regulators and what each one controls

What license is needed to establish a financial institution in Turkey?

Establishing a bank requires a license from the BRSA under the Banking Law No. 5411, granted in a two-stage process: an establishment permit, then an operating permit before the institution can take deposits or extend credit. Applicants must meet a minimum paid-in capital set by law and regulation, demonstrate sound governance, submit a viable business plan, and pass fit-and-proper assessments for qualifying shareholders and senior management. Securities activities need separate authorization from the CMB under Law No. 6362.

The capital floor and specific documentary requirements differ by institution type and are fixed by regulation rather than by the statute itself, so confirm the figure and the document list in force at the time of application. Payment institutions and electronic-money institutions follow a distinct licensing track under Law No. 6493, and non-bank lenders such as factoring, leasing, and financing companies are licensed under their own dedicated legislation, all under BRSA oversight.

Types of regulated financial institutions

• Deposit banks: take deposits and extend credit; the core of the commercial banking system.
• Development and investment banks: provide long-term financing for industry and infrastructure without taking deposits.
• Participation banks: operate on interest-free (Islamic) principles, offering Sharia-compliant products under BRSA supervision.
• Capital-market intermediaries: CMB-licensed firms for brokerage, portfolio management, and investment advisory.
• Payment and electronic-money institutions: licensed under Law No. 6493 for payment services and e-money.
• Factoring, leasing, and financing companies: non-bank financial institutions under dedicated BRSA-supervised legislation.

How are cross-border banking and finance transactions regulated?

Cross-border financial transactions are regulated through several layers at once: the foreign-exchange regime overseen by the Central Bank (CBRT/TCMB), AML/KYC obligations under MASAK, sector rules from the BRSA and CMB, and tax obligations including withholding on interest and dividend payments to non-residents. Foreign investors benefit from the equal-treatment principle of the Foreign Direct Investment Law No. 4875, which guarantees national treatment and free transfer of profits and capital, subject to applicable tax and reporting rules. A private account can also be stopped from the payment side: since December 25, 2025 a bank may suspend an account used in qualified fraud, qualified theft or bank card misuse for up to 48 hours under Article 128/A of the Code of Criminal Procedure, and what that means after a peer-to-peer transfer is set out in bank account blocked in Turkey after P2P.

Equal treatment does not remove sector-specific scrutiny. Foreign acquisition of a bank or insurer triggers BRSA change-of-control approval and enhanced review, and correspondent and syndicated structures must satisfy both Turkish rules and international standards such as the FATF Recommendations and Wolfsberg Group principles. Where a financing dispute arises, parties commonly select arbitration or a governing-law clause that must be enforceable in Turkey, which is why documentation and forum selection are decided at the outset.

Key cross-border structures

• Foreign direct investment: regulatory approvals, sector limits, and reporting for capital entering the financial sector.
• Correspondent banking: compliance with domestic AML rules plus FATF Recommendations and Wolfsberg principles.
• Syndicated lending: multi-jurisdiction loan documentation, governing-law selection, security, and intercreditor terms.
• Capital-markets access: cross-listing, prospectus, and investor-protection standards under CMB rules.
• Project and acquisition finance: structuring with international lenders, development banks, and export-credit agencies, including change-of-control approvals, for capital-intensive regulated projects such as those governed by nuclear energy law and regulatory compliance.

What is the legal framework for fintech and digital finance?

Fintech in Turkey runs primarily on the Payment and Securities Settlement Systems Law No. 6493, which sets the licensing regime for payment institutions and electronic-money institutions, supervised by the BRSA. Open banking, digital-only banks, and crowdfunding are layered on top through BRSA and CMB secondary regulation, while cryptocurrency activity sits within an evolving framework anchored to the Capital Markets Law No. 6362. Every licensed provider must also satisfy AML obligations under MASAK and data rules under KVKK Law No. 6698.

Because the digital-finance rules change frequently through secondary regulation, the license category and the exact capital and safeguarding thresholds should be confirmed against the version in force when you file. For the data-protection and crypto side, our technology law, data privacy, and crypto practice advises on the overlap between financial services and digital products.

What are the consequences of non-compliance with banking regulation?

Non-compliance under the Banking Law No. 5411 can lead to administrative fines, restriction or suspension of activities, required management changes, and in serious cases license revocation, transfer of management, or resolution proceedings. The BRSA holds broad enforcement powers, and separate criminal liability can attach to responsible individuals, particularly for AML failures under MASAK supervision. Fine amounts and thresholds are set by statute and regulation, so the figure applicable to a given breach should be confirmed against the rules in force at the time.

For internationally active groups, the practical exposure is cumulative: a single transaction can simultaneously breach BRSA, CMB, MASAK, and KVKK requirements, which is why a documented compliance program matters more than any single approval.

Litigation or arbitration for a cross-border financing dispute?

For cross-border financing disputes, the choice between Turkish court litigation and international arbitration usually turns on enforceability and neutrality. Arbitral awards are enforced across more than 170 states under the New York Convention, subject only to the limited refusal grounds in Article V, which makes arbitration attractive where assets or counterparties sit in multiple jurisdictions. Litigation in the Turkish courts can be more direct for domestic security enforcement under the Enforcement and Bankruptcy Law No. 2004.

Most well-drafted cross-border facility agreements settle this in advance through a clear governing-law and dispute-resolution clause. Our international arbitration and international commercial litigation teams structure that clause so the chosen forum is actually enforceable against the assets that matter.

Why engage banking and finance counsel?

Banking and finance counsel matters because the framework is multi-regulator and the cost of a misstep is high: a missing BRSA approval can void a transaction, and a weak security package can leave a lender unsecured in enforcement. Counsel maps the activity to the right statute and regulator, secures the licenses and approvals, drafts enforceable documentation, and builds the compliance backbone that keeps an internationally active institution out of enforcement.

• Regulatory advisory: licensing, change-of-control approvals, and ongoing BRSA, CMB, and MASAK compliance.
• Transaction structuring: loan agreements, syndicated facilities, structured and project finance documentation.
• Security and collateral: pledges, mortgages, and assignments that are valid, enforceable, and correctly ranked.
• Compliance design: AML/KYC programs, internal audit, and regulatory reporting.
• Dispute resolution: regulatory proceedings, enforcement, and international arbitration involving financial institutions.
• Participation banking: Sharia-compliant product structuring with dual regulatory and Sharia compliance.
• Financial-services M&A: acquisitions and disposals of banks and insurers, including approvals and competition review.
