Turkish CBI US$500,000 government bonds: Regulations and holding period

The Turkish CBI US$500,000 government bond option is one of 4 qualifying investment options under the citizenship by investment programme of Türkiye. This option allows investors to purchase government bonds with a minimum value of US$500,000 and commit to holding them for 3 years — in exchange for naturalization rights for the whole family without needing to own tangible assets.

Compared to the US$400,000 real estate option (which accounts for over 90% of applications), the government bond option is less popular but is prioritized by investors seeking liquidity, capital preservation, and those who want to avoid the risks of managing assets. The article provides a detailed analysis of the legal framework, qualifying bonds, market interest rates for the 2024-2026 period, the blocking process, and the risks investors need to anticipate when participating Türkiye Citizenship by Investment programme through this option.

Legal framework of the Turkish CBI US$500,000 government bond option

The legal basis for the bond option is found in Article 20 of the Regulation on the Implementation of the Turkish Citizenship Law No. 5901. This document clearly defines qualifying government bonds as debt instruments issued by the Turkish Ministry of Treasury and Finance — excluding corporate bonds, local government bonds, or foreign bonds.

Specific regulations on eligible instrument types are listed in Law No. 4749 on Public Debt Management and Law No. 4632 on the Private Pension System. According to announcements from the Ministry of Treasury and Finance of Türkiye, the three main recognised instrument categories comprise domestic government debt securities (Devlet İç Borçlanma Senetleri – DİBS), international bonds (Eurobonds) and asset lease certificates (Kira Sertifikası – Islamic law-compliant sukuk).

The enforcement and validation authority is the Ministry of Treasury and Finance of Türkiye. Once the investor completes the transaction and requests the bank to block the bond portfolio for 3 years, the bank must submit a report to the Ministry. The Ministry reviews the conditions and issues a Certificate of Conformity – a mandatory document in the citizenship application file.

3 types of qualifying Turkish CBI bonds

The implementing regulations permit investors to purchase three main types of government debt instruments. Each carries distinct risk profiles, interest rates and transaction procedures.

Type 1: Domestic government debt securities (DİBS)

These are Lira-denominated bonds issued in the domestic market. The Ministry of Treasury issues DİBS with various maturities ranging from 3 months to 10 years, following a weekly auction schedule. The nominal interest rate of DİBS in 2026 fluctuates around 30-35% per year depending on maturity – reflecting tight monetary policy aimed at controlling inflation.

However, CBI investors typically avoid DİBS due to Lira exchange rate risk. The Lira depreciated significantly over the 2022-2025 period – high nominal interest rates are offset by currency devaluation when converted to USD. USD-converted actual yields over the past 3 years have generally been negative 5-10% per year.

DİBS are only suitable for investors with a long-term investment strategy in the Turkish economy who accept exchange rate risk. For investors seeking USD-converted capital preservation, other bond types are more appropriate.

Type 2: Turkish international Eurobonds

This is the preferred choice for international CBI investors. Turkish Eurobonds are government bonds issued in USD or EUR in international markets (London, Luxembourg, Frankfurt). This type is not exposed to Lira exchange rate risk as both principal and interest are paid in major foreign currencies.

Turkish Eurobonds come in various series with maturities from 5 to 30 years. Nominal interest rates depend on maturity and issuance timing. Certain series referenced in 2026 offer yields of approximately 7-12% per year in USD – significantly higher than US Treasury bonds of the same maturity thanks to the sovereign risk premium.

Investors purchase Eurobonds via securities accounts opened at investment banks operating in Türkiye. The bonds are deposited at Merkezi Kayıt Kuruluşu (MKK) – the Central Registry Agency of Türkiye. The 3-year blocking procedure is executed via a notation on the depository account.

Type 3: Asset lease certificates (Kira Sertifikası – Sukuk)

These are sharia-compliant financial instruments issued by the Ministry of Treasury through a public asset-leasing SPV company. Turkish sukuk are issued in both Lira and USD, sharing a cash flow structure and government credit guarantee similar to Eurobonds.

USD sukuk yields fluctuate between 6-10% per year depending on maturity, generally slightly lower than traditional Eurobonds of the same maturity. This instrument suits investors from Islamic markets (Middle East, Indonesia, Malaysia) wishing to adhere to religious financial principles. For Vietnamese investors, sukuk offers no particular advantage over Eurobonds.

Bond purchase and blocking process

The implementation process for the USD 500,000 Turkish government bond CBI option involves six main steps.

1. Opening a securities account at a Turkish investment bank: the bank must hold a securities brokerage license issued by the Capital Markets Board of Türkiye (SPK). Several popular banks maintain service branches for foreign investors.
2. Obtaining a Turkish tax number and proof of capital source: preparing 6-12 month account statements, tax returns and AML verification documents as required by the bank.
3. Transferring USD/EUR to the account and obtaining the DAB document: capital transferred from abroad via the banking system must be certified by Central Bank of the Republic of Türkiye (TCMB) through a DAB. The total DAB value must be ≥ US$500,000.
4. Submitting a bond purchase order: the investment bank executes the trade on the secondary market or registers for a primary issuance subscription. Investors have the right to select series, maturity and currency according to their risk appetite.
5. Three-year block on the depository account: the bank records a sell-restriction note on the account, accompanied by the investor’s confirmation signature. The 3-year period is calculated from the date of the final block (if purchasing in multiple tranches).
6. Reporting and applying for the Certificate of Conformity: the bank submits the file to the Ministry of Treasury and Finance. The Ministry reviews it within 4-6 weeks and issues the Certificate of Conformity for the investor to proceed with residency permit and citizenship applications.

The entire process from account opening to receiving the Certificate usually takes 2-3 months. Investors may grant Power of Attorney to local legal counsel to execute most steps, eliminating the need for continuous presence in Türkiye.

Rights and obligations during the 3-year holding period

Unlike the real estate option, bond investors continue to receive periodic interest throughout the 3-year holding period. This represents a key advantage in generating stable cash flow.

Investors are entitled to receive all coupon interest (for traditional Eurobonds) or periodic interest (for DİBS and sukuk) throughout the holding period. This interest is unblocked and may be withdrawn to personal accounts or reinvested at the investor’s discretion. With an investment of US$500,000 in Eurobonds yielding 8% per year, the 3-year interest cash flow amounts to approximately US$120,000 before tax – substantially offsetting the capital opportunity cost.

Taxation on government bond interest applies via a withholding tax mechanism. The withholding rate for foreign individual investors is generally 0% for Eurobonds and USD sukuk (exempted under Turkish law and Double Taxation Avoidance agreements – DTAs), and 10% for Lira DİBS. Vietnam and Türkiye signed a DTA in 1996 which remains in force – Vietnamese investors may benefit from tax privileges under this agreement.

The investor’s primary obligation is to maintain a blocked value of ≥ US$500,000 continuously for 3 years. If the market value of the bonds falls below US$500,000 due to interest rate fluctuations, the investor must supplement additional bonds to secure the threshold. Any changes (supplements, conversions between government bond types) must be reported to the Ministry of Finance immediately upon completion of the transaction.

Actual interest rates and yields for the 2024-2026 period

Analysing the actual yields of various Turkish government bonds assists investors in making appropriate capital allocation decisions.

Five-year Turkish Eurobonds issued in late 2024 carry a nominal interest rate of approximately 7.5-8.5% per year in USD. Series TUR-30 (30-year maturity) carries a rate of 11.875% per year. Yield to maturity (YTM) changes according to secondary market prices, fluctuating between 7-12% depending on timing. Total interest received over 3 years on a US$500,000 investment in 8% Eurobonds is approximately US$120,000 before tax.

Turkish USD sukuk issued in 2024-2025 offer yields of 6-9% per year depending on maturity. Credit risk levels match Eurobonds as both are issued by the government. Total 3-year interest on US$500,000 placed in 7% sukuk is approximately US$105,000.

Lira DİBS feature the highest nominal interest rates (30-35% per year in 2026) but entail substantial exchange rate risk. Over the past 3 years, the Lira depreciated by roughly 25-40% against the USD. Once converted, the actual USD yield of DİBS can be negative – making them unsuitable for USD-converted capital preservation investors.

In summary, for Vietnamese investors, the optimal strategy is to allocate the entire US$500,000 into USD-denominated Eurobonds or sukuk with 5-7 year maturities. This structure ensures stable USD cash flows, avoids Lira exchange rate risk, and maintains the capacity for resale after 3 years with minimal market slippage.

Risks and important considerations

Although considered the “safest” option among the four Turkish CBI routes, government bond investment still entails four risk categories requiring thorough evaluation.

Risks sovereign risk relating to the possibility of the Turkish Government defaulting or restructuring its debt. Türkiye’s credit rating in 2026 stands at B+ (according to S&P) – falling within the speculative grade category. This rating has improved compared to the 2022-2023 crisis period but remains notably higher than developed nations. Türkiye has no history of defaulting on Eurobonds; however, its credit default swap (CDS) spread in 2026 still fluctuates between 250-350 basis points.

Risks interest rate the market price impact of bonds during the 3-year holding period. When market interest rates rise, the price of existing bonds falls, and vice versa. With a remaining maturity of 5-10 years after the 3-year holding period, price volatility may fall within the range of ±10-15% of the initial price. However, if the investor holds the bond until maturity, they receive the full face value plus periodic coupons.

Risks secondary market liquidity occurs when, after 3 years, the Turkish Eurobond secondary market cannot immediately absorb a large volume. Investors may need to sell gradually over multiple sessions or accept a discount compared to the reference price. This issue is less severe for series with large issuance volumes but should be noted for series with low trading activity.

Risks policy and legal relates to the possibility of the Turkish Government adjusting CBI regulations after the investor has already invested. Although the programme has been stable since 2022, some other CBI countries have previously changed conditions abruptly (e.g., Cyprus closed its programme in 2020). Investors should carefully read the contract terms with the investment bank to understand the protection mechanisms in case of legislative changes.

Comparison with the other 3 Turkish CBI options

To select the optimal option, investors need to compare government bonds with the other 3 options based on 4 basic criteria: capital threshold, cash flow, legal complexity, and asset ownership rights.

Compared to US$400,000 real estate, government bonds require a higher capital threshold (US$500,000 vs US$400,000) but are much simpler in terms of legal procedures — no TAPU, no SPK valuation, and no risk of inflated valuations. Real estate has the potential for asset appreciation, while bonds only offer fixed interest. For investors who prioritise capital preservation and liquidity, bonds are a safer choice.

Compared to US$500,000 bank deposit, these 2 options are quite similar in terms of liquidity and complexity. The main difference is the interest rate — Eurobonds are typically 1-2 percentage points higher than USD deposit rates at Turkish banks. However, deposits have the advantage of 100% face value stability, without market price volatility.

Compared to 50-employee job creation option, bonds are a completely passive investment option. The job creation option requires actual business operations, demanding a long-term commitment and an understanding of business in Türkiye — it is not suitable for the majority of Vietnamese investors coming from other industries.

Conclusion and next steps

The Türkiye CBI US$500,000 government bond option is suitable for Vietnamese investors who prioritise USD-denominated capital preservation, high liquidity, and wish to avoid asset operational risks. This option generates a cash flow of US$105,000-120,000 in interest over 3 years (with Eurobonds or USD sukuk at 7-8% interest) — significantly offsetting the opportunity cost of capital compared to the deposit option.

The optimal strategy for Vietnamese investors is to allocate the entire US$500,000 into 5-7 year USD-denominated Turkish Eurobonds, combined with a local lawyer to handle the blocking process and apply for the Certificate of Conformity. To understand more about the programme context, investors can refer to Turkish CBI overview 2026 and Turkish passport and the US E-2 route — 2 articles providing an overall framework of the programme’s strategic benefits and entitlements.

Before implementation, investors need to complete opening a Turkish bank account and obtaining a Defter tax number — 2 mandatory procedures before placing a bond purchase order. At the same time, Vietnamese documents must be consularly legalised in 3 steps (before 11/09/2026) or Apostilled (from 11/09/2026 when the Hague Apostille Convention takes effect in Vietnam) before being submitted with the residence permit application.
