Türkiye’s Evolving Model Investment Treaties Redraw the Risk Map for Foreign Capital
Türkiye’s bilateral investment treaty policy has evolved from broad, investor-focused protection toward a more detailed framework that preserves arbitration while placing tighter conditions on who qualifies for protection, which assets are covered, and when claims may proceed. A newly published study of eight previously difficult-to-access Turkish model treaties shows that this transition began well before the current global debate over investor-state dispute settlement. For foreign companies evaluating Türkiye, the central lesson is practical: treaty protection increasingly depends on how an investment is structured, authorized, capitalized and operated from its first day.
Previously Unavailable Texts Reveal a Long Policy Evolution
The analysis, prepared by Selim Can Bilgin and Arda Ömer Kasap of Kabine Law Office and published by Mondaq in October 2026, examines eight Turkish model bilateral investment treaties, or BITs, dating from 2000 to 2014. Six of the texts were obtained from the Ministry of Industry and Technology through Türkiye’s Presidency Communication Centre, known as CİMER, following a July 28, 2026 response to an information request.
The collection includes models from 2000, 2004, 2005, 2006, two versions from 2009, January 2010 and January 2014. The United Nations Conference on Trade and Development had previously published only Türkiye’s 2000 and May 2009 models. UNCTAD’s Investment Policy Hub also records Turkish model treaties from 2016 and 2024, but their full texts are not publicly available.
That opacity matters. A model BIT is not itself a binding treaty, but it is the government’s negotiating template. It can reveal which protections the state seeks to extend to its investors abroad and which liabilities it is prepared to accept when foreign investors enter its own market. The final agreement may differ because of negotiations, especially where the parties have unequal economic leverage.
Türkiye’s Ministry of Trade says the country has signed BITs with 98 states, of which 76 are in force. The ministry describes the program as a means of increasing bilateral capital and technology flows while protecting both foreign investors in Türkiye and Turkish companies abroad against non-commercial risks.
Recent treaty activity shows the program remains active. UNCTAD records investment treaties signed with Cuba, Iraq, Tajikistan and the Republic of Congo during 2024. It also lists a new Türkiye-Kazakhstan BIT signed on May 14, 2026, although it was not yet in force in the database’s latest update. The Türkiye-Hong Kong investment agreement, signed in October 2023, entered into force on February 4, 2026.
Core Protections Remain, but Their Boundaries Have Tightened
All eight models retain the familiar foundations of investment protection: fair and equitable treatment, full protection and security, national treatment, most-favoured-nation treatment, compensation for expropriation and the free transfer of investment proceeds. They also permit investor-state arbitration through the World Bank’s International Centre for Settlement of Investment Disputes, or through an ad hoc tribunal applying UNCITRAL rules.
Türkiye’s 2000 model followed the expansive style common to older treaties. It defined investments broadly, covering property, shares, monetary claims, intellectual property and natural-resource concessions. It contained no general exception safeguarding regulatory authority and did not specify that legitimate public-welfare regulation falls outside the concept of indirect expropriation.
The first changes were procedural. The 2005 model clarified that the treaty did not apply to disputes arising before its entry into force. In 2006, Türkiye added language limiting arbitration to investment activities that had received any required permissions and had effectively commenced. Disputes concerning ownership and rights in rem over immovable property were reserved for Turkish courts.
Bilgin and Kasap connect these provisions to Türkiye’s notification under Article 25(4) of the ICSID Convention and to the PSEG v. Türkiye arbitration. In that case, the tribunal found that the notification was not a reservation and could not independently narrow treaty consent where the applicable BIT contained no corresponding limitation. Incorporating the restriction directly into subsequent treaty language gave it greater legal force.
For investors, this distinction is critical. A signed memorandum, preliminary expenditure or expectation of receiving a licence may not amount to an effectively commenced and protected investment. Regulatory permissions, capital contributions, land rights and the documented start of operations can determine whether a tribunal has jurisdiction years later.
Regulatory Space Entered the Model in 2009
The 2009 model marked the clearest substantive shift. Its preamble stated that investment protection should be achieved without relaxing generally applicable health, safety and environmental measures or internationally recognized labour rights.
A new right-to-regulate provision covered non-discriminatory measures protecting life, health, the environment and natural resources, as well as essential security interests. The expropriation article further stated that non-discriminatory measures designed and applied to protect legitimate public-welfare objectives generally would not constitute indirect expropriation.
This language reflected a broader international movement following arbitral decisions such as Methanex v. United States and Saluka v. Czech Republic. Those cases helped develop the principle that good-faith, non-discriminatory public-interest regulation does not ordinarily require compensation, even if it affects an investment’s economic value.
Türkiye also refined the definition of a protected investor. Corporate claimants were required to conduct real or substantial business activities in their state of incorporation. The 2014 model added a denial-of-benefits clause allowing treaty protection to be refused where a company lacked substantial business activities in its nominal home state and was owned or controlled by investors from a third state or the host country.
These provisions directly affect corporate structuring. Establishing a holding company in a favourable treaty jurisdiction shortly before a dispute will not necessarily secure protection. Foreign groups need to demonstrate commercial substance, including management activity, personnel, decision-making and an operational rationale beyond access to arbitration.
The 2009 model also prevented most-favoured-nation treatment from being used to import more favourable procedural rights from another treaty. By 2010, the restriction expressly covered dispute-settlement provisions. This responded to the line of jurisprudence following Maffezini v. Spain, where investors sought to use most-favoured-nation clauses to bypass conditions in the treaty governing their own investment.
Access to Arbitration Is Increasingly Conditional
The post-2009 models offer investors a choice between domestic courts and international arbitration, but impose a fork-in-the-road rule. Once a forum is selected, the choice is generally final for the same dispute.
This makes early dispute strategy unusually consequential. Litigation started by a local subsidiary, even for immediate operational reasons, could complicate a later treaty claim. Investors must distinguish contractual, administrative and treaty causes of action before initiating proceedings or accepting dispute clauses in concessions, licences and public contracts.
Later Turkish treaties appear to narrow access further. Based on recurring language in agreements signed after 2014, the Mondaq study concludes that protected assets increasingly must possess objective characteristics such as a commitment of capital or resources, an expectation of profit, assumption of risk, a certain duration and, in many cases, a contribution to economic development.
Many later agreements also limit arbitration to an alleged treaty breach that causes loss or damage to the investor or its investment. Negotiation periods, proof that the investment effectively commenced and restrictions on using most-favoured-nation treatment to expand arbitration remain recurring features.
These are not theoretical distinctions. ICSID reported 63 new cases during calendar year 2025, its second-highest annual total, with BITs providing the jurisdictional basis for 58 percent of new cases. Of the cases decided by tribunals that year, 11 percent were dismissed for lack of jurisdiction. Jurisdictional design therefore remains as important as the merits of an investor’s complaint.
Türkiye’s own 2025 record was comparatively quiet. Jus Mundi’s 2025 arbitration review reported no new treaty claims against the state during the year, although existing proceedings continued. The review highlighted the planned resolution of Alamos Gold v. Türkiye following the September 2025 agreement to sell the Canadian miner’s Turkish assets to TÜMAD for $470 million. The underlying claim, brought under the Netherlands-Türkiye BIT, reportedly exceeded $1 billion and concerned the non-renewal of permits for mining projects in Çanakkale.
Treaty Modernization Accompanies a Renewed FDI Push
The more qualified treaty framework is developing alongside an official effort to attract higher-value foreign investment. According to the Presidency’s Investment and Finance Office, Türkiye received $13.1 billion in FDI during 2025, 12.2 percent more than in 2024. Treasury and Finance Minister Mehmet Şimşek said inflows excluding real estate reached $10.7 billion, their highest level in a decade.
Wholesale and retail trade accounted for 32 percent of 2025 inflows, manufacturing for 31 percent, and information and communications for 14 percent. The Netherlands was the largest source country, followed by Luxembourg and Kazakhstan.
The government’s 2024,2028 FDI Strategy seeks to raise Türkiye’s share of global investment flows to 1.5 percent by 2028, with priorities including advanced manufacturing, digital transformation, green investment and integration into global value chains. This ambition operates within a difficult international environment. UNCTAD’s World Investment Report 2026 found that global FDI increased 6 percent to $1.6 trillion in 2025, but described the recovery as fragile and concentrated. More than 80 percent of inflows went to the top 20 recipient economies.
Türkiye’s treaty approach reflects that dual position. It wants legal protections sufficient to attract foreign capital and protect expanding Turkish businesses overseas, while retaining policy space for environmental regulation, security measures, balance-of-payments controls and other public objectives.
What This Means for Foreign Investors
A BIT should be treated as one component of market-entry planning, not as an emergency remedy reviewed only after a dispute begins. Investors should confirm that the relevant treaty is in force, determine whether their proposed asset and corporate vehicle meet its definitions, and examine exclusions, cooling-off periods, local-court provisions and consent to arbitration.
Company incorporation and corporate structuring require particular care. The legal entity claiming treaty nationality may need substantial business activities in its home jurisdiction, while indirect ownership chains should have a defensible commercial purpose. Restructuring after a dispute becomes foreseeable may fail to create jurisdiction.
Legal and tax compliance is equally important because Turkish treaties generally protect investments made in accordance with host-state law. Licensing, competition approvals, tax registrations, environmental permissions, land rights and sector-specific authorizations should therefore be documented as part of the investment record. Government-relations and regulatory-liaison work can help identify which approvals are legally required and which authority controls each stage.
Investment incentives also need to be integrated with treaty and contract analysis. An incentive certificate, tax benefit or project-specific undertaking may create important rights, but it does not automatically become a treaty obligation, particularly because Türkiye’s model texts generally omit an umbrella clause. Import-export structures and profit-repatriation plans should likewise account for treaty transfer protections, tax rules, customs requirements and possible balance-of-payments exceptions.
Finally, project management should preserve evidence of capital deployment, operational commencement, regulatory correspondence and compliance decisions. In Türkiye’s increasingly precise treaty system, the strongest protection is built into the investment before capital is committed, through coordinated market entry, incorporation, incentives, compliance and government engagement.
