Introduction
Debt instruments in Turkey are among the most important financing tools used by companies, banks, financial institutions and other issuers to raise funds through the capital markets. Unlike shares, which represent equity participation, debt instruments generally represent a borrowing relationship between the issuer and the investor. The investor provides funds to the issuer, and the issuer undertakes to repay principal, interest, discount return or another financial obligation under the terms of the relevant instrument.
In Turkish capital market practice, debt instruments may include bonds, bills, financing bills, convertible bonds, exchangeable bonds, precious metal bills and other capital market instruments accepted by the Capital Markets Board of Türkiye as debt instruments. The Capital Markets Board of Türkiye, known as the CMB in English and SPK in Turkish, describes debt instruments as instruments issued by issuers as debtor, including bonds, convertible bonds, exchangeable bonds, financing bills, precious metal bills and other capital market instruments accepted by the Board as debt instruments by their nature.
The primary legal framework is Capital Markets Law No. 6362, together with the Debt Securities Communiqué VII-128.8, the Communiqué on Prospectus and Issue Document II-5.1, the Communiqué on Sales of Capital Market Instruments II-5.2, Borsa İstanbul listing rules and other CMB regulations. The CMB’s current capital market legislation page lists the Debt Securities Communiqué VII-128.8 under capital market instruments, alongside the prospectus, sales, shares, foreign instruments and lease certificate regulations.
For issuers, debt instruments provide an alternative to bank loans and equity financing. For investors, they offer a structured return profile, but they also carry credit risk, liquidity risk, interest rate risk, currency risk and issuer default risk. Therefore, debt instrument issuance in Turkey is strictly regulated to protect investors and maintain transparency in the capital markets.
Legal Nature of Debt Instruments
Debt instruments are capital market instruments that create a debtor-creditor relationship between the issuer and investors. The issuer obtains funds from investors and undertakes repayment according to the terms of the instrument. These terms may include maturity, interest rate, discount rate, coupon payment dates, redemption conditions, early redemption provisions, conversion rights, exchange rights, security structure and default consequences.
The most common form is the bond, usually issued with a maturity and interest payment obligation. Bills or financing bills are generally shorter-term debt instruments used for liquidity and working capital financing. Convertible bonds give investors the right to convert the debt instrument into shares of the issuer under predetermined conditions. Exchangeable bonds may provide the right to exchange the debt instrument for shares of another company or another asset, depending on the structure. Precious metal bills are linked to precious metal values and may be relevant for issuers and investors seeking exposure to that asset class.
From a legal perspective, classification matters. Once an instrument is treated as a debt security or debt instrument under Turkish capital market law, the issuer must comply with CMB rules regarding authorization, issuance ceiling, offering documents, sales method, public disclosure, registration, listing and investor protection.
Main Legal Framework
The main regulation specifically governing debt instrument issuance is the Debt Securities Communiqué VII-128.8. The SPK’s application guidance states that debt instruments are subject to the provisions of the Debt Securities Communiqué VII-128.8, published in the Official Gazette dated 7 June 2013 and numbered 28670.
The Debt Securities Communiqué regulates the principles to be followed in debt instrument issuances and the qualities of debt instruments to be issued. The SPK’s official legislation system identifies the Debt Securities Communiqué VII-128.8 as a regulation dated 7 June 2013 and published in Official Gazette No. 28670 under the section concerning issuance of capital market instruments, public disclosure and issuers.
Debt instrument issuances must also be assessed together with the prospectus and sales communiqués. The SPK states that in capital market instrument issuance applications, including debt instruments, the relevant instrument-specific communiqué must be considered together with the Prospectus and Issue Document Communiqué II-5.1 and the Sales of Capital Market Instruments Communiqué II-5.2.
Therefore, an issuer should not review only one regulation. A Turkish bond or bill issuance may require analysis of Capital Markets Law No. 6362, the Debt Securities Communiqué, prospectus rules, issue document rules, sales rules, Borsa İstanbul listing rules, financial reporting rules, public disclosure rules, tax law and, where the issuer is a bank or regulated financial institution, sector-specific rules.
Types of Debt Instruments in Turkey
Turkish capital market law recognizes several types of debt instruments. The SPK’s application guidance expressly lists bonds, convertible bonds, exchangeable bonds, financing bills, precious metal bills and other instruments accepted by the Board as debt instruments by their nature.
Bonds are generally medium or long-term debt instruments. They may have fixed interest, floating interest, discount structure, periodic coupon payments or other repayment structures. Bonds are often used by large companies, banks and financial institutions to raise funding from institutional or retail investors.
Financing bills are usually shorter-term instruments. They may be preferred by issuers that need short-term liquidity or working capital financing. Investors may use them as fixed-income instruments with shorter duration exposure.
Convertible bonds are hybrid instruments because they begin as debt but may later convert into shares of the issuer. These instruments are useful where investors want downside protection through debt features and upside potential through equity conversion.
Exchangeable bonds are also hybrid in nature. Instead of conversion into the issuer’s own shares, the investor may have rights connected to shares of another company or another asset depending on the transaction structure.
Precious metal bills may be designed with reference to precious metals and may serve investors seeking a debt instrument linked to precious metal exposure.
Each instrument has different legal, financial and investor protection consequences. A convertible bond, for example, may affect share capital, dilution, shareholder rights and corporate approvals. A short-term bill may create liquidity and refinancing risk. A secured or asset-backed structure may require additional legal review.
Issuer Decision and Corporate Authorization
Before issuing debt instruments in Turkey, the issuer must obtain a valid decision from its competent corporate body. The SPK’s application guidance expressly states that a decision of the issuer’s authorized body is mandatory for debt instrument issuance.
This requirement is not a mere formality. The authorized corporate body decision should clearly identify the type of debt instrument, issuance amount or ceiling, maturity structure, domestic or foreign issuance, public offering or non-public sale method, currency, interest or return structure, possible security, intermediary institution and other essential terms.
For joint-stock companies, the corporate decision must also be compatible with the company’s articles of association, Turkish Commercial Code rules and capital market regulations. If the issuer is a bank, leasing company, factoring company, financing company, investment firm or another regulated entity, sector-specific approvals or notifications may also be required.
A defective corporate authorization may jeopardize the issuance. Investors, intermediaries, the CMB or Borsa İstanbul may question whether the issuer lawfully approved the transaction. Therefore, companies should obtain legal review before submitting applications.
Issuance Ceiling
Debt instrument issuances in Turkey often involve an issuance ceiling. The issuer applies to the CMB for approval of a maximum amount within which one or more issuances may be conducted during the applicable period. This allows issuers to access markets in tranches, depending on funding needs and market conditions.
Borsa İstanbul states that an application for listing debt securities and lease certificates may be filed either for a one-off issue covering a predetermined amount in full or to cover all issuances to be made in tranches within an issue ceiling approved by the CMB within a certain period.
The issuance ceiling is commercially useful because interest rates, investor demand and liquidity conditions may change. An issuer may obtain approval for a ceiling and then issue different tranches when market conditions are favorable. However, each tranche must still comply with CMB and Borsa İstanbul procedures where applicable.
For investors, issuance ceiling approval does not mean that every future tranche has identical risk. Each tranche may have different maturity, interest rate, currency, security, investor base or sales method. Therefore, investors should review the specific terms of the relevant tranche.
Public Offering of Debt Instruments
Debt instruments may be issued through public offering. In this case, the issuer targets a broad investor base and must comply with prospectus, sales, disclosure and listing rules. Public offering creates more intensive investor protection obligations because retail investors may participate.
A public offering of bonds or bills generally requires a prospectus approved by the CMB, unless a specific exemption applies. The prospectus must disclose the issuer’s financial condition, debt structure, risk factors, repayment capacity, use of proceeds, terms of the instrument, rights of investors and default consequences.
Borsa İstanbul states that debt securities and lease certificates offered to the public can be listed and traded on the Exchange. It also explains that, where instruments are issued under a CMB-approved issuance ceiling, the portion whose sale is completed starts trading in the Debt Securities Market after an announcement on the Public Disclosure Platform.
For issuers, public offering may provide access to a wide investor base and improve visibility. For investors, public offering provides more extensive disclosure. However, it does not eliminate credit risk. A publicly offered bond may still default if the issuer cannot meet its obligations.
Listing Requirements for Debt Securities Through Public Offering
Borsa İstanbul imposes specific requirements for debt securities issued through public offering to be listed. According to Borsa İstanbul, at least two calendar years must have passed since the issuer’s establishment. The issuer’s recent CMB-compliant and independently audited financial statements must show total shareholders’ equity greater than capital, and the issuer must have obtained net profit in at least one of its financial statements relating to the last two annual accounting periods.
Borsa İstanbul also requires that the issuer’s financial situation enable it to carry out and continue its business operations in a healthy manner. The issuer must not be subject to significant legal disputes affecting its production and other activities, and an independent lawyer must issue a legal report confirming that the issuer’s establishment, operations and debt securities comply with applicable laws and regulations.
This legal report requirement is important. It shows that debt instrument issuance is not purely financial. Legal due diligence is also required. The lawyer should review corporate establishment, business permits, material disputes, corporate authorizations, debt instrument terms and legal compliance.
Borsa İstanbul notes that these requirements are not requested for issues of asset-backed or mortgage-backed securities and covered securities. This distinction reflects the special legal and asset-based structure of those instruments.
Sale to Qualified Investors
Debt instruments in Turkey may also be issued for sale to qualified investors. This method is often used for institutional investors, professional investors, banks, funds, portfolio management companies and sophisticated investors. It may provide a more flexible route than a retail public offering.
Borsa İstanbul states that debt securities and lease certificates issued for sale to qualified investors are listed without any assessment by the Exchange following approval of the prospectus by the CMB and completion of sales.
The Offering Market for Qualified Investors is the market where debt securities of issuers defined in the relevant CMB communiqué are issued to qualified investors in accordance with CMB regulations. Debt securities issued in this market begin trading as unlisted securities on the Outright Purchases and Sales Market after completion of the issuance or expiry of the issuance period, without further requirements.
Only qualified investors may buy debt securities in the Offering Market for Qualified Investors. Borsa İstanbul states that investment firms acting as intermediaries are responsible for checking and monitoring whether investors are qualified investors under capital market regulations.
This responsibility is critical. If non-qualified investors are improperly included in a qualified investor issuance, regulatory and civil liability may arise. Intermediary institutions must document investor status and maintain records.
Issuance Period in the Qualified Investor Market
The issuance period for debt securities issued in the Offering Market for Qualified Investors cannot exceed 10 days. Borsa İstanbul states that the whole issue amount declared to the Exchange must be sold in the market, although an additional period may be provided by Borsa İstanbul management for the unsold part; at the end of the second period, the offering of the remaining unsold part must be cancelled.
This rule is commercially important. Issuers and intermediaries must plan investor demand carefully before launching the transaction. If demand is insufficient, the unsold portion may not remain indefinitely available. Pricing, maturity, investor communication and documentation must be aligned with the issuance timetable.
Private Placement and Non-Public Issuance
Debt instruments may also be issued without public offering, including private placement structures. In such cases, a full public offering prospectus may not always be required, but an issue document and CMB application may still be necessary depending on the structure.
The SPK’s application guidance states that, depending on whether the issuance is a public offering or non-public sale through private placement or sale to qualified investors, an application is made to the CMB with the information and documents specified in the relevant annexes of the Debt Securities Communiqué. The prospectus or issue document formats to be prepared according to the issuance type are also available on the CMB’s website.
Issuers should be careful not to convert a private placement into a public offering through broad marketing. Public-facing advertisements, social media campaigns, open invitations, website announcements or general solicitation may create public offering risk. A private placement must be limited, controlled and documented.
Foreign Debt Instrument Issuances
Turkish issuers may also issue debt instruments abroad. Foreign issuances require separate compliance analysis involving Turkish CMB rules, foreign securities law, tax, currency, listing, custody and settlement matters.
The SPK has launched a Foreign Issuance Tracking System for debt instrument tranches to be issued abroad. According to the SPK, under Article 6 of the Debt Securities Communiqué VII-128.8, the system enables applications to be made to the CMB by electronic signature before the sale of each tranche in debt instrument issuances to be conducted abroad.
This is especially relevant for Turkish companies and financial institutions issuing Eurobonds or foreign-currency debt securities in international markets. Even where the issuance is outside Turkey, Turkish CMB procedures may still apply.
Foreign issuances should also be reviewed under the laws of the target jurisdiction. For example, an offering to investors in the European Union, United Kingdom, United States or Gulf markets may require compliance with local securities exemptions, offering restrictions, listing rules and disclosure standards.
Bonds and Bills as Corporate Financing Tools
Debt instruments are attractive because they allow companies to raise funds without diluting shareholders. Unlike equity offerings, bonds and bills do not give investors ownership rights unless the instrument includes conversion or exchange rights. This makes debt issuance useful for companies that want financing but do not want to change their shareholding structure.
However, debt financing increases leverage. The issuer must repay principal and interest regardless of profitability, unless the terms provide otherwise. Excessive debt may create insolvency risk, refinancing pressure and covenant breaches.
Before issuing bonds or bills, companies should analyze their cash flow, debt maturity profile, interest rate exposure, currency exposure, EBITDA, liquidity, collateral capacity and refinancing options. A debt issuance that appears attractive in the short term may create serious long-term risk if the company cannot generate sufficient cash flow.
Investor Risks in Debt Instruments
Investors often perceive bonds and bills as safer than shares, but this perception can be misleading. Debt instruments carry several important risks.
Credit risk is the risk that the issuer cannot pay principal or interest. Interest rate risk is the risk that market interest rates rise, reducing the value of existing fixed-rate instruments. Liquidity risk is the risk that the investor cannot sell the instrument before maturity at a fair price. Currency risk arises where the instrument is denominated in foreign currency or linked to foreign currency. Inflation risk reduces real return. Subordination risk arises where the investor ranks behind other creditors. Early redemption risk may affect expected return if the issuer redeems the instrument earlier than anticipated.
Investors should read the prospectus or issue document carefully. The most important parts are issuer financials, risk factors, maturity, interest structure, ranking, security, default provisions, use of proceeds and any covenants.
Secured and Covered Debt Instruments
Some debt instruments may be secured or covered by assets. Security may reduce investor risk but does not eliminate it. The value, enforceability, priority and liquidity of the collateral must be examined.
Turkish capital market regulations also include rules concerning secured or covered capital market instruments and asset-backed or mortgage-backed securities. The SPK’s 2020 announcement regarding amendments to the Debt Securities Communiqué and asset-backed or mortgage-backed securities rules stated that certain measures were introduced to encourage issuances by mortgage finance institutions and funds established by such institutions, including rules concerning issuance limits and fee reductions.
For investors, the key question is not only whether an instrument is “secured” but how the security works. Which assets are pledged? Who monitors them? What is the coverage ratio? What happens if asset value falls? How is enforcement conducted after default? Are investors represented collectively?
Debt Instrument Holders’ Meeting
Debt instrument holders may need to act collectively, especially when the issuer faces financial difficulty or seeks restructuring of terms. Turkish law introduced a specific framework for debt instrument holders’ meetings.
The SPK announced the Debt Instrument Holders’ Meeting Communiqué II-31/A.1 in 2020. According to the SPK, the communiqué regulates the functioning of the debt instrument holders’ meeting system, the determination of representatives, meetings, participation of secured instruments in decisions and issues concerning breach of payment obligations and restructuring of debt instruments.
This framework is important because individual bondholders may not be able to negotiate effectively with the issuer. Collective decision-making allows investors and issuers to agree on amendments, restructuring or enforcement-related matters in a more organized way.
For issuers, this system provides a legal route to restructure debt instruments where market conditions change. For investors, it provides a mechanism to protect collective interests instead of relying only on individual enforcement.
Default and Restructuring
Default occurs when the issuer fails to meet payment obligations or breaches material terms of the debt instrument. Default consequences depend on the instrument terms, prospectus or issue document, applicable law, security structure and any collective investor decision mechanism.
Possible consequences include acceleration, default interest, enforcement of security, restructuring negotiations, debt instrument holders’ meeting, litigation, execution proceedings or insolvency procedures. If the issuer is a regulated financial institution, sector-specific resolution or supervisory rules may also apply.
Investors should not wait until maturity if warning signs appear. Deteriorating financial statements, delayed disclosures, rating downgrades, liquidity problems, litigation, covenant breaches or market rumors should be monitored carefully through official disclosures.
Issuers should communicate transparently with investors. Concealing repayment risk may create regulatory and civil liability. Early restructuring may be more effective than default.
Borsa İstanbul Debt Securities Market
Debt instruments may be traded on Borsa İstanbul’s Debt Securities Market. Listing and trading provide liquidity, price transparency and access to a wider investor base. However, exchange trading does not guarantee that investors can always sell at the desired price.
Borsa İstanbul states that debt securities and lease certificates offered to the public or issued for sale to qualified investors can be listed and traded on the Exchange. Applications may cover a one-off issue or all tranches under a CMB-approved issuance ceiling.
For issuers, listing may improve investor confidence and visibility. For investors, trading on the Debt Securities Market provides a regulated secondary market. However, liquidity may vary by instrument, maturity, issuer credit quality and market conditions.
Disclosure Obligations After Issuance
Issuers of debt instruments may have ongoing disclosure obligations, especially if the instruments are listed or the issuer is a public company. Material developments affecting repayment capacity, financial condition, security, covenants, rating, restructuring, default or early redemption may require public disclosure.
The Public Disclosure Platform is an important infrastructure for listed instruments. Borsa İstanbul states that the portion of capital market instruments whose sale is completed starts trading in the Debt Securities Market following an announcement in the Public Disclosure Platform.
Investors should monitor KAP announcements, financial statements, payment notices, redemption notices and any disclosures concerning default, restructuring or issuer financial difficulty.
Tax Considerations
Debt instruments may create tax consequences for both issuers and investors. Interest income, discount income, capital gains, withholding tax, corporate tax deductibility, foreign investor treatment and double tax treaty issues may all be relevant.
The tax treatment depends on the investor type, issuer type, instrument, maturity, currency, residence status and applicable legislation. Because tax rules may change, issuers and investors should obtain current tax advice before issuing or investing in bonds and bills.
Tax should be reviewed at the structuring stage. A debt instrument that is legally valid may still be commercially inefficient if withholding tax, accounting treatment or deductibility issues are ignored.
Liability Risks for Issuers
Issuers may face liability if they provide misleading information, fail to disclose material risks, issue debt instruments without proper authorization, breach payment obligations or misstate financial capacity.
The prospectus or issue document must accurately reflect the issuer’s financial condition and repayment capacity. If investors buy debt instruments based on misleading disclosure and suffer loss, civil liability may arise. The CMB may also impose administrative sanctions where capital market rules are violated.
Directors and managers should be careful when approving issuance documents. They should not present debt instruments as risk-free. They should disclose existing debt, cash flow pressure, litigation, regulatory risks, currency exposure and other material factors affecting repayment.
Liability Risks for Intermediary Institutions
Intermediary institutions involved in debt instrument issuances must act within their authorization and comply with CMB rules. They must ensure that sales are conducted in accordance with the approved documents and investor classification rules.
In qualified investor sales, intermediary institutions are responsible for checking and monitoring whether investors qualify as qualified investors. Failure to do so may create regulatory and civil exposure.
Intermediaries should also avoid misleading marketing. Statements such as “guaranteed return,” “no default risk,” or “bank-level safety” may be dangerous unless legally and factually accurate. Risk disclosures should be clear and balanced.
Practical Checklist for Issuers
A company planning a debt instrument issuance in Turkey should follow a structured checklist.
First, determine the type of instrument: bond, bill, financing bill, convertible bond, exchangeable bond or another debt instrument. Second, obtain a valid authorized body decision. Third, determine whether the issuance will be public, private, to qualified investors or abroad. Fourth, calculate the issuance ceiling and maturity structure. Fifth, prepare the prospectus or issue document. Sixth, complete CMB application requirements. Seventh, appoint authorized intermediary institutions where required. Eighth, analyze Borsa İstanbul listing rules. Ninth, conduct legal and financial due diligence. Tenth, prepare ongoing disclosure, payment and investor relations systems.
This checklist should be completed before approaching investors. A debt issuance marketed before proper legal preparation may create public offering, disclosure and liability problems.
Practical Checklist for Investors
Investors should review the issuer approaching investors. A debt issuance marketed before proper legal preparation may’s financial condition, debt level, cash flow, maturity profile, credit rating if available, security structure, payment terms, liquidity, risk factors, tax treatment and default provisions.
Investors should also verify whether the instrument is publicly offered, sold to qualified investors, privately placed or issued abroad. They should read the prospectus or issue document and avoid relying only on marketing materials.
For retail investors, the most important warning is that a bond is not the same as a bank deposit. Debt instruments may lose value and may default. Higher yield usually means higher risk.
Conclusion
Debt instruments in Turkey are essential capital market financing tools. They allow issuers to raise funds through bonds, bills, financing bills, convertible bonds, exchangeable bonds, precious metal bills and other debt securities accepted by the CMB. They provide investors with fixed-income or structured return opportunities, but they also carry credit, liquidity, interest rate, currency and default risks.
The legal framework is based primarily on Capital Markets Law No. 6362, the Debt Securities Communiqué VII-128.8, the prospectus and sales communiqués, Borsa İstanbul listing rules and related CMB regulations. The SPK expressly states that debt instrument issuances are governed by the Debt Securities Communiqué VII-128.8 and that issuers th the documents required according to the issuance method. citeturn159461search3
Debt instruments may be publicly offered, privately placed, sold to qualified investors or issued abroad. Each route has different legal requirements. Public offerings require strong disclosure. Qualified investor sales require proper investor classification. Foreign issuances require Turkish and foreign law analysis. Listing on Borsa İstanbul may provide liquidity and transparency but also imposes additional conditions.
For issuers, compliance begins with corporate authorization and continues through CMB applications, prospectus or issue document preparation, sales procedures, listing, disclosure and repayment. For investors, protection depends on careful review of issuer risk, official documents and market disclosures. For intermediary institutions, compliance requires authorization, documentation, investor classification and fair marketing.
In conclusion, bonds and bills in Turkey are powerful financing and investment instruments, but they must be structured and evaluated carefully. Any company planning a debt instrument issuance, any investor considering investment in Turkish bonds or bills, and any foreign issuer or intermediar targeting Turkish investors should obtain professional legal advice before acting.
