Public Debt Law and Constitutional Limits in Turkey

Introduction to Public Debt Regulation

Sovereign debt—borrowing by the state—is a normal and necessary aspect of public finance. However, because excessive debt can threaten economic stability and impose burdens on future generations, most countries impose legal and constitutional limits on government borrowing.

In Turkey, state borrowing is regulated primarily by Law No. 4749 on Regulating Public Finance and Debt Management and by constitutional provisions requiring parliamentary oversight of fiscal matters.

Constitutional Framework

Parliamentary Control

The Turkish Constitution enshrines the principle that only the Parliament can authorize state borrowing. This is part of the broader “Budget Right” (Bütçe Hakkı) that reserves fiscal decisions to the people’s elected representatives.

Article 163 of the Constitution addresses supplementary budgets and transfers between appropriations, while Article 164 covers borrowing authorization.

Annual Authorization

The government’s borrowing authority is granted annually through the Budget Law and, where needed, specific borrowing laws. The annual borrowing limit (borçlanma limiti) is a key fiscal policy tool.

Law No. 4749: Overview

Law No. 4749 on Regulating Public Finance and Debt Management (Kamu Finansmanı ve Borç Yönetiminin Düzenlenmesi Hakkında Kanun), enacted in 2002, provides the comprehensive legal framework for:

• Domestic borrowing
• Foreign borrowing
• Treasury guarantees
• Cash management
• Debt servicing and restructuring

Key Institutions

Institution	Role
Ministry of Treasury and Finance	Primary authority for debt management
Undersecretariat of Treasury	Operational management of borrowing
Central Bank of the Republic of Turkey	Fiscal agent for domestic debt instruments
Turkish Grand National Assembly	Authorization and oversight

Types of State Borrowing

Domestic Borrowing

The Treasury raises funds in the domestic market through:

1. Government Bonds (Devlet Tahvili)

• Fixed or floating rate
• Maturities typically 2-10 years
• Sold through auctions to primary dealers

2. Treasury Bills (Hazine Bonosu)

• Short-term instruments (under one year)
• Sold at discount to face value
• Used for cash management

3. Lease Certificates (Sukuk)

• Islamic finance-compliant instruments
• Asset-based financing structure
• Growing portion of domestic debt

Foreign Borrowing

The Treasury borrows internationally through:

1. Eurobonds

• Bonds issued in international markets
• Denominated in foreign currencies (USD, EUR)
• Subject to international capital market conditions

2. Official Lending

• Loans from international financial institutions (World Bank, IMF)
• Bilateral government-to-government lending
• Often tied to specific projects or programs

3. Project Finance

• Loans for specific infrastructure projects
• May have Treasury guarantees

Borrowing Limits

Annual Debt Ceiling

The Budget Law sets an annual borrowing limit that caps the net increase in government debt. This limit is expressed as a percentage of the anticipated budget deficit.

Key features:

• Net Borrowing Limit: Total new borrowing minus principal repayments
• Gross Borrowing: Total securities issued (may exceed net limit for refinancing)
• Flexibility Margin: A percentage buffer for unexpected needs

Excess Borrowing Authorization

If circumstances require borrowing beyond the annual limit, the government must obtain special parliamentary authorization through a supplementary budget or specific legislation.

Constitutional Court Review

Borrowing legislation is subject to review by the Constitutional Court for compliance with constitutional principles, including:

• Legality principle (borrowing only as authorized by law)
• Fiscal discipline requirements
• Separation of powers

Treasury Guarantees

The Treasury may issue guarantees (Hazine garantisi) for loans extended to:

• State economic enterprises
• Publicly-owned infrastructure projects
• Public-private partnership arrangements

Guarantee Limits

Law 4749 establishes limits on outstanding Treasury guarantees as a percentage of GDP or budget revenues. Guarantees create contingent liabilities that can become actual debt if the borrower defaults.

Guarantee Review

Parliamentary oversight extends to guarantee authorizations, with periodic reporting on:

• Outstanding guarantees by sector and entity
• Guarantee fees collected
• Claims paid under guarantees

Debt Management Strategy

Principles

Turkish debt management follows principles of:

• Cost Minimization: Reducing borrowing costs over the medium term
• Risk Management: Balancing interest rate, currency, and refinancing risks
• Transparency: Regular publication of debt data and strategy
• Market Development: Deepening domestic debt markets

Medium-Term Debt Management Strategy

The Treasury publishes a Medium-Term Debt Management Strategy that outlines:

• Target debt composition (domestic vs. foreign, fixed vs. floating)
• Currency composition targets
• Average maturity objectives
• Refinancing risk management

Cash Management

Alongside debt management, Treasury conducts cash management to ensure:

• Timely payment of government obligations
• Minimization of idle cash balances
• Coordination between revenue collection and expenditure timing
• Short-term borrowing needs are met efficiently

Cash management operations include:

• Treasury single account (Hazine Tek Hesabı)
• Short-term advances from the Central Bank (within limits)
• Domestic debt instrument issuance timing

Accountability and Transparency

Reporting Requirements

The Treasury must provide regular reports to Parliament and the public on:

• Outstanding debt stock and composition
• Borrowing costs and interest payments
• Guarantee position
• Risk metrics (duration, currency exposure)

Court of Accounts Audit

The Sayıştay audits Treasury debt management operations for:

• Compliance with legal limits
• Proper authorization of borrowing
• Accurate recording and reporting
• Risk management effectiveness

Fiscal Rules

While Turkey does not have constitutionally entrenched fiscal rules (like debt-to-GDP limits found in some countries), the government adheres to:

• Medium-Term Program fiscal targets
• Maastricht-type criteria for EU accession (historically)
• IMF program conditionality (when applicable)
