Introduction
Turkey is a strategically important market for foreign investors, international lenders, private equity funds, development finance institutions, export credit agencies, multinational companies and cross-border borrowers. Its location between Europe, Asia and the Middle East, its large domestic market, developed banking sector, industrial base and active infrastructure projects make Turkey a significant destination for financing transactions.
However, financing an investment or business operation in Turkey requires careful legal planning. Turkish finance law is not limited to loan agreements. It includes banking regulation, foreign exchange rules, collateral law, corporate approvals, tax considerations, enforcement procedures, capital markets rules, anti-money laundering obligations, data protection requirements and cross-border dispute resolution.
For foreign investors, the most important legal questions are usually practical: Can a Turkish company borrow from a foreign lender? Can the loan be denominated in foreign currency? What collateral can be granted in Turkey? How can a mortgage, pledge or guarantee be enforced? Are there restrictions on money transfers abroad? Can foreign arbitral awards be enforced in Turkey? How should loan agreements be structured to reduce risk?
This article provides a comprehensive overview of Turkish finance law for foreign investors, with a particular focus on loans, collateral and cross-border transactions.
1. General Legal Environment for Foreign Investors in Turkey
Turkey generally permits foreign direct investment and provides a legal framework designed to protect foreign investors. The Foreign Direct Investment Law No. 4875 aims to encourage foreign direct investments, protect the rights of foreign investors, define investment and investor concepts in line with international standards and establish a notification-based system rather than a screening-and-approval regime for foreign direct investments.
Foreign investors are generally subject to equal treatment with domestic investors, unless otherwise provided by international agreements or special laws. The foreign investment framework also recognizes the right to freely transfer abroad net profits, dividends, proceeds from sale or liquidation, compensation payments, licensing fees, management fees and similar payments related to foreign investments.
This general investment framework is important for finance transactions. A foreign investor acquiring shares in a Turkish company, establishing a subsidiary, financing a local project or providing shareholder loans should consider both the foreign investment rules and the finance-specific rules applicable to loans, collateral and foreign exchange.
2. Turkish Banking and Finance Regulatory Framework
The main statute regulating banks in Turkey is Banking Law No. 5411. The purpose of this law is to ensure confidence and stability in financial markets, support the efficient functioning of the credit system and protect the rights and interests of depositors. The law applies to deposit banks, participation banks, development and investment banks, foreign bank branches, financial holding companies, the Banking Regulation and Supervision Agency, the Savings Deposit Insurance Fund and relevant banking sector associations.
The Banking Regulation and Supervision Agency, known as the BRSA or BDDK, is the main regulatory authority for banks. It supervises the establishment and operation of banks, banking activities, capital adequacy, liquidity, internal systems, corporate governance, loan classifications, risk management, banking confidentiality and regulatory compliance.
Foreign investors should distinguish between financing through Turkish banks, foreign banks, shareholder loans, capital markets instruments and private credit structures. Each route may have different requirements. For example, a Turkish bank loan will be governed by Turkish banking practice and BRSA rules, while a foreign lender loan may trigger foreign exchange rules, withholding tax questions, collateral perfection issues and cross-border enforcement analysis.
3. Loan Agreements in Turkey
Loan agreements in Turkey may be governed by Turkish law or foreign law depending on the transaction structure. In domestic commercial lending, Turkish law-governed loan agreements are common. In syndicated loans, acquisition finance, project finance and international credit facilities, foreign law-governed facility agreements may be used, often with Turkish law-governed security documents.
A finance transaction involving a Turkish borrower should normally address the following matters:
The amount and currency of the loan, purpose of the loan, conditions precedent, drawdown procedure, repayment schedule, interest rate, default interest, fees, tax gross-up, withholding tax risk, representations and warranties, undertakings, financial covenants, information undertakings, events of default, acceleration rights, governing law, jurisdiction, arbitration, collateral package and enforcement mechanics.
The loan agreement should also be consistent with Turkish mandatory law. Even if a facility agreement is governed by foreign law, Turkish law issues may arise in relation to capacity, authority, collateral, insolvency, enforcement, public policy, tax, foreign exchange and regulatory compliance.
For foreign investors, the key point is that the commercial terms of the loan must be supported by an enforceable Turkish law structure. A well-drafted loan agreement is not sufficient if the borrower lacked corporate authority, the collateral was not perfected, foreign exchange rules were breached or the enforcement mechanism is unclear.
4. Foreign Currency Loans and Decree No. 32
Foreign currency loans are a critical issue in Turkish finance law. Turkey has a detailed foreign exchange regime under Decree No. 32 on the Protection of the Value of Turkish Currency and related communiqués. These rules regulate foreign currency borrowing, foreign exchange-indexed obligations, foreign currency contracts and cross-border money flows.
Foreign currency loan restrictions are especially important for Turkish resident borrowers. In general, Turkish resident legal entities may be subject to conditions when borrowing foreign currency loans from abroad or from Turkish financial institutions. The rules have been amended over time, and eligibility may depend on whether the borrower has foreign currency income, whether an exemption applies, the type of borrower, the loan amount, the purpose of the loan and the lender type.
Recent amendments to Decree No. 32 have also affected guarantees and sureties related to foreign currency and precious metal loans. Legal commentary on the 2025 amendments notes that direct shareholders or group companies of Turkish resident borrowers may provide foreign currency or precious metal-denominated guarantees and sureties to Turkish resident banks and financial institutions as security for such loans, subject to the amended framework.
Because foreign exchange legislation changes periodically, foreign lenders and investors should not rely on general assumptions. Before signing a foreign currency loan, the parties should verify whether the borrower is eligible, whether the loan must be intermediated through a Turkish bank, whether reporting obligations apply and whether guarantees, pledges or sureties are compatible with current rules.
5. Cross-Border Lending to Turkish Borrowers
Cross-border lending is common in Turkey, especially in acquisition finance, project finance, infrastructure finance, energy finance, export finance and corporate refinancing. A foreign lender may lend directly to a Turkish borrower, participate in a syndicated loan, provide mezzanine financing, extend a shareholder loan or finance a Turkish investment through a foreign holding company.
From a Turkish law perspective, cross-border lending requires analysis of:
Borrower capacity, corporate approvals, foreign currency eligibility, tax treatment, withholding tax, stamp tax, exchange control rules, collateral creation, perfection, registration, notarization, apostille, legal opinions, enforcement routes and dispute resolution.
Foreign lenders should also determine whether they need a license in Turkey. Merely lending from abroad to a Turkish corporate borrower does not automatically mean that the lender is conducting banking business in Turkey. However, if a foreign entity systematically markets financial services, opens a branch, accepts deposits or conducts regulated activities in Turkey, licensing issues may arise.
The distinction between cross-border lending and local regulated activity should be reviewed carefully in each transaction.
6. Corporate Authority and Conditions Precedent
Before disbursing funds, foreign lenders should verify that the Turkish borrower has legal capacity and corporate authority to enter into the finance documents. The borrower’s articles of association, trade registry records, board decisions, signature circulars, shareholder approvals and internal authorization documents should be reviewed.
Typical conditions precedent in Turkish finance transactions include:
Corporate documents, board resolutions, shareholder resolutions where required, signature authorities, tax registration documents, financial statements, legal opinions, security documents, registration evidence, notarized documents, land registry documents, pledge registry confirmations, insurance policies, consents, permits, payment instructions and evidence of no material adverse change.
Where the borrower is part of a group, lenders should also examine whether guarantees or security provided by related companies comply with corporate benefit, financial assistance, capital maintenance and management liability principles.
7. Collateral and Security Interests in Turkish Finance Law
Collateral is central to finance law. Foreign lenders often require Turkish law security over assets located in Turkey. The most common security instruments include:
Mortgages over immovable property, pledges over movable assets, share pledges, bank account pledges, assignment of receivables, commercial enterprise pledges, guarantee agreements, suretyships, promissory notes, letters of guarantee and contractual subordination arrangements.
The validity and enforceability of collateral depend on Turkish law. Even if the main loan agreement is governed by foreign law, security over Turkish assets must generally be created and perfected under Turkish law.
A collateral package should be designed according to the borrower’s asset structure. A real estate company may provide mortgages over land and buildings. A manufacturing company may provide movable pledges over machinery, inventory and receivables. A holding company may provide share pledges. A project company may provide account pledges, receivables assignments and mortgage security.
8. Mortgages Over Immovable Property
A mortgage is one of the strongest forms of security in Turkish finance transactions. It is created over immovable property and must be registered with the land registry. Without proper registration, a mortgage over real estate will not be perfected.
Foreign lenders commonly require mortgages over land, factories, hotels, commercial buildings, residential projects, energy facilities or other real estate owned by the borrower or a third-party security provider.
The mortgage agreement and land registry records should clearly identify the secured obligations, mortgage amount, degree, currency, creditor, debtor and mortgaged property. If the loan is denominated in foreign currency, the mortgage structure should be reviewed carefully under Turkish law and foreign exchange rules.
Enforcement of mortgages generally takes place through Turkish enforcement offices. The creditor may initiate mortgage enforcement proceedings, and the mortgaged property may be sold through enforcement procedures if the debt remains unpaid.
9. Movable Pledges in Commercial Transactions
Movable assets may also be pledged as security in Turkey. Law No. 6750 on Pledges over Movable Property in Commercial Transactions introduced a modern non-possessory movable pledge regime designed to facilitate access to finance, especially for commercial enterprises. Legal commentary notes that the law replaced the previous commercial enterprise pledge regime and introduced a centralized registry for movable collateral, allowing non-possessory pledges over a broad range of movable assets.
Movable pledge security may cover machinery, equipment, inventory, raw materials, receivables, intellectual property rights, trade names, commercial projects, livestock, agricultural products and similar assets, depending on the applicable legal framework.
This type of security is important because many businesses do not want to deliver possession of their operating assets to lenders. A non-possessory pledge allows the borrower to continue using the assets while granting security to the lender.
However, the pledge must be properly registered and described. The collateral description should be specific enough to avoid enforcement disputes. Lenders should also monitor whether the pledged assets are insured, maintained, transferred, replaced or sold in the ordinary course of business.
10. Share Pledges
Share pledges are frequently used in acquisition finance, project finance and private equity transactions. A lender may require a pledge over the shares of the Turkish borrower or project company. This allows the lender to enforce against the ownership interest if the borrower defaults.
The rules depend on whether the shares are in a joint stock company or a limited liability company, whether the shares are certificated, whether they are registered or bearer shares, and whether the articles of association contain transfer restrictions.
A share pledge should be documented carefully and perfected according to Turkish law. For limited liability company shares, notarization and registration issues may arise. For joint stock company shares, physical possession, endorsement, share ledger registration and other perfection steps may be relevant depending on the share type.
Foreign lenders should not treat share pledges as simple contractual documents. Perfection requirements, corporate records and enforcement mechanics must be reviewed carefully.
11. Bank Account Pledges
Bank account pledges are common in project finance, acquisition finance and structured finance transactions. The borrower or project company may pledge its bank accounts to the lender. These accounts may include revenue accounts, collection accounts, reserve accounts, debt service accounts and operating accounts.
A bank account pledge agreement should identify the pledged accounts, secured obligations, account bank, control mechanics, withdrawal restrictions, enforcement triggers and set-off rights. Notice to the account bank and acknowledgment by the account bank are important for practical enforceability.
In project finance, cash waterfall mechanisms are often used. Revenue flows into a collection account and is applied in a predetermined order: taxes, operating expenses, debt service, reserve funding and distributions. The account pledge supports the lender’s control over project cash flows.
12. Assignment of Receivables
Assignment of receivables is another common security tool. A borrower may assign receivables arising from customer contracts, lease agreements, insurance claims, project agreements, concession contracts, export receivables or intra-group receivables.
The assignment may be structured as an outright assignment or security assignment. The debtor may need to be notified depending on the structure and enforcement strategy. If receivables are future receivables, the assignment language should be drafted carefully.
In cross-border finance, receivables assignments are particularly important where the borrower’s main assets are contractual cash flows rather than real estate. For example, in energy projects, hotel finance, infrastructure finance or export finance, receivables may represent the core value of the collateral package.
13. Guarantees and Suretyships
Guarantees and suretyships are frequently used in Turkish finance transactions. A parent company may guarantee the obligations of its Turkish subsidiary. Shareholders may provide guarantees. Group companies may support the borrower’s repayment obligations.
However, Turkish law makes important distinctions between guarantee-like obligations. A true independent guarantee, an ordinary suretyship, a joint and several suretyship and a letter of guarantee may have different validity and enforcement consequences.
For individual sureties, Turkish law imposes strict form requirements. Spousal consent, handwritten maximum amount, date and other requirements may become relevant. For corporate guarantees, corporate authority and corporate benefit should be reviewed.
Foreign investors should also consider whether foreign currency guarantees are permitted under foreign exchange rules. As noted above, recent amendments to Decree No. 32 have affected guarantees and sureties related to foreign currency and precious metal loans.
14. Letters of Guarantee
Letters of guarantee issued by Turkish banks are commonly used in commercial and finance transactions. They may secure payment obligations, performance obligations, bid obligations, advance payments, customs obligations or lease obligations.
A bank letter of guarantee is usually treated as a strong payment instrument because the bank undertakes to pay the beneficiary subject to the terms of the letter. However, disputes may arise regarding demand conditions, expiry dates, fraud, abuse of rights, underlying contract disputes and injunction requests.
Foreign investors receiving or providing Turkish bank letters of guarantee should review the wording carefully. The letter should state whether it is payable on first demand, whether supporting documents are required, whether it is definite or indefinite, and whether Turkish courts may issue interim measures in case of abusive demand.
15. Tax and Stamp Duty Issues
Finance transactions in Turkey may trigger tax and stamp duty considerations. Loan agreements, security documents, guarantees, assignments and other transaction documents may need to be reviewed from a Turkish tax perspective.
Withholding tax may arise depending on the lender, borrower, loan type, maturity and applicable double tax treaty. Stamp tax may apply to written agreements unless an exemption applies. Banking and insurance transaction tax may also be relevant in certain banking transactions.
Tax structuring should be addressed before signing. It is risky to treat tax as an afterthought because gross-up clauses, tax indemnities, payment mechanics and transaction costs may materially affect the commercial economics of the deal.
Foreign lenders should request tax advice on withholding, stamp tax, VAT, BITT, double tax treaties and tax gross-up provisions before disbursement.
16. Capital Markets and Bond Financing
Foreign investors may also finance Turkish companies through capital markets instruments, including bonds, notes, sukuk, asset-backed securities or other debt instruments. These transactions may fall under the Capital Markets Law No. 6362 and the supervision of the Capital Markets Board of Turkey.
The Capital Markets Law states that its purpose is to regulate and supervise capital markets to ensure their functioning and development in a secure, transparent, efficient, stable, fair and competitive environment and to protect the rights and interests of investors.
Debt capital markets financing may be attractive for large Turkish companies, banks, financial institutions and infrastructure projects. However, public offerings, private placements, prospectus requirements, investor disclosure, listing rules, custody, settlement and cross-border selling restrictions must be reviewed carefully.
For foreign investors, the key distinction is whether the instrument is offered publicly, privately, domestically, internationally or only to qualified investors. Each structure has different regulatory consequences.
17. Project Finance in Turkey
Project finance is commonly used in energy, infrastructure, transportation, healthcare, public-private partnership projects, ports, airports, industrial facilities and large real estate developments. In project finance, lenders rely primarily on the cash flow of the project rather than the general credit of the sponsors.
A Turkish project finance structure typically includes a project company, sponsor support, construction contracts, operation and maintenance contracts, offtake agreements, concession agreements, insurance packages, direct agreements, step-in rights, account pledges, receivables assignments, mortgages, movable pledges and share pledges.
Foreign lenders should carefully review permits, licenses, land rights, environmental obligations, tariff mechanisms, force majeure clauses, termination compensation, public authority approvals and dispute resolution clauses.
The success of project finance depends on the enforceability of the entire security and contractual package. A weakness in one document may affect the bankability of the project.
18. Cross-Border Payments and Repatriation
Foreign investors usually want clarity on repatriation of profits, dividends, loan repayments, interest payments and sale proceeds. Turkish foreign investment law generally permits free transfer abroad of net profits, dividends, proceeds from sale or liquidation, payments arising from license, management and similar agreements, and principal and interest payments of foreign loans, subject to applicable laws and tax obligations.
In practice, banks may request supporting documents for cross-border transfers. These may include loan agreements, invoices, board resolutions, tax documents, shareholder resolutions, dividend distribution documents, sale agreements or regulatory filings.
Foreign investors should maintain proper documentation. Even where a transfer is legally permitted, banks may delay processing if the transaction purpose, source of funds or supporting documents are unclear.
19. Anti-Money Laundering and Sanctions Compliance
Banks and financial institutions in Turkey are subject to anti-money laundering and counter-terrorist financing obligations. Law No. 5549 on Prevention of Laundering Proceeds of Crime establishes the main legal framework for preventing money laundering in Turkey.
Foreign investors and lenders should expect Turkish banks to conduct customer due diligence, beneficial ownership checks, source-of-funds inquiries, sanctions screening and transaction monitoring. Complex ownership structures, offshore entities, politically exposed persons, high-risk jurisdictions or unusual payment flows may trigger enhanced due diligence.
In finance transactions, AML compliance should be addressed from the beginning. Borrowers should prepare corporate documents, ownership charts, financial statements, tax records, transaction explanations and evidence of source of funds.
20. Dispute Resolution and Enforcement
Finance documents involving foreign investors often include arbitration clauses or foreign court jurisdiction clauses. However, enforcement in Turkey must be analyzed carefully.
Foreign arbitral awards may be enforced in Turkey under the New York Convention and Turkish International Private and Procedural Law No. 5718, subject to procedural and substantive conditions. Recent legal commentary confirms that the New York Convention provides the overarching international framework, while Turkish private international law contains procedural rules applied by Turkish courts.
Foreign court judgments may also be recognized and enforced in Turkey under Law No. 5718, subject to conditions such as finality, reciprocity, proper jurisdiction, due process and public policy compatibility.
For secured lenders, dispute resolution is only one part of enforcement. Security over Turkish assets may still need to be enforced through Turkish execution offices or Turkish courts. Therefore, the dispute resolution clause should be consistent with the collateral enforcement strategy.
21. Practical Checklist for Foreign Investors and Lenders
Foreign investors and lenders should follow a structured legal checklist before entering into a Turkish finance transaction.
First, identify the borrower and confirm corporate authority. Second, determine whether the loan can be denominated in foreign currency. Third, review foreign exchange rules under Decree No. 32. Fourth, analyze tax and stamp duty consequences. Fifth, structure the collateral package under Turkish law. Sixth, verify registration and perfection requirements for mortgages, pledges and assignments. Seventh, review corporate benefit and guarantee capacity. Eighth, prepare conditions precedent. Ninth, ensure AML and source-of-funds documentation is available. Tenth, select dispute resolution and enforcement mechanisms that work together.
This checklist should be tailored to the transaction. A shareholder loan, syndicated loan, project finance facility, acquisition finance loan and bond issuance will each require different legal analysis.
22. Common Legal Risks in Turkish Finance Transactions
Foreign investors frequently encounter several risks in Turkish finance transactions.
The first risk is foreign currency non-compliance. A loan may be commercially agreed in foreign currency, but the borrower may not be eligible under current Turkish foreign exchange rules.
The second risk is defective collateral. A mortgage, pledge or assignment may be signed but not properly registered, notified or perfected.
The third risk is insufficient corporate authority. A borrower or guarantor may not have obtained proper board or shareholder approvals.
The fourth risk is unclear enforcement strategy. A lender may have a favorable arbitration award but still face difficulty enforcing security over Turkish assets.
The fifth risk is tax leakage. Withholding tax, stamp tax or other transaction costs may reduce expected returns.
The sixth risk is AML documentation failure. Banks may refuse or delay transfers if the transaction documents or ownership structure are unclear.
23. Why Legal Support Is Essential
Turkish finance law is highly technical because it combines banking law, foreign exchange regulation, secured transactions, corporate law, tax law, enforcement law, capital markets law and international private law.
A Turkish finance lawyer may assist foreign investors with loan structuring, collateral packages, foreign currency eligibility, Decree No. 32 analysis, mortgage registration, movable pledge registration, share pledges, receivables assignments, guarantee documentation, legal opinions, tax coordination, CP checklists, enforcement strategy and dispute resolution clauses.
Legal support is especially important before signing. Once a loan has been disbursed, it may be difficult to fix defective collateral, missing approvals, foreign exchange issues or tax problems. In finance transactions, prevention is usually more effective than litigation.
Conclusion
Turkish finance law offers significant opportunities for foreign investors, lenders and multinational companies. Turkey’s legal framework permits foreign investment, cross-border financing, secured lending and repatriation of investment-related proceeds, subject to applicable regulatory, tax and compliance rules.
However, finance transactions involving Turkey must be structured carefully. Foreign currency loans must be reviewed under Decree No. 32. Collateral must be created and perfected under Turkish law. Corporate approvals must be obtained properly. Tax and stamp duty consequences must be calculated in advance. Cross-border payments must be supported by clear documentation. Dispute resolution clauses must be compatible with Turkish enforcement realities.
For foreign investors, the most successful finance structures are those that combine commercial flexibility with legal precision. A strong Turkish law review can protect the lender, support the borrower, reduce enforcement risk and make the transaction bankable.
Whether the transaction involves a shareholder loan, syndicated facility, project finance loan, acquisition financing, bond issuance, real estate mortgage, movable pledge, share pledge, guarantee or receivables assignment, professional legal guidance is essential. In Turkish finance law, the strength of a transaction depends not only on the loan amount or interest rate, but also on the enforceability of the legal structure behind it.
