Foreign Investment in Real Estate and Housing Rights: Regulating Speculation Without Breaching International Economic Obligations

Author – Tamanna Verma

 

Introduction

The increasing global movement of capital has transformed real estate from a largely domestic asset into an international investment opportunity. Foreign investment in the real estate sector has contributed to economic growth by bringing in capital, supporting infrastructure development, and promoting housing and urban projects. At the same time, the growing involvement of foreign investors in residential property markets has raised concerns about speculative investment, which can drive up property prices and reduce housing affordability. As housing increasingly becomes an investment asset rather than simply a basic human need, governments face the challenge of encouraging economic development while ensuring that housing remains accessible to all.

This issue has important legal implications because housing is conferred not only as an economic asset but also as a fundamental human right under international human rights law. At the same time, states are bound by international economic obligations under Bilateral Investment Treaties (BITs), Free Trade Agreements (FTAs), and other investment agreements that protect foreign investors from arbitrary or discriminatory state action. As a result, measures such as restrictions on foreign ownership, vacancy taxes, or anti-speculation policies, although intended to improve housing affordability, may be challenged as being inconsistent with these investment commitments. This creates a legal tension between a State’s duty to protect the right to housing and its obligation to provide a stable and predictable investment environment.

This intersection of foreign investment, housing rights, and international economic law raises an important legal question that to what extent can a State regulate its real estate market in the public interest without breaching its international investment obligations? As governments increasingly introduce measures to improve housing affordability and limit speculative investment, finding the right balance has become more important than ever. Such a balance is necessary not only to maintain investor confidence but also to ensure that housing remains affordable and accessible. It is therefore important to examine how a State’s regulatory powers can be exercised while remaining consistent with its international economic commitments and its responsibility to protect the right to adequate housing.

Foreign Investment in Real Estate

Foreign investment in real estate refers to the acquisition, development, or financing of immovable property by non-resident individuals, corporations, or institutional investors. It generally takes the form of Foreign Direct Investment (FDI), which enables foreign capital to participate in housing, commercial infrastructure, and urban development projects. Many states encourage such investment because it supplements domestic capital, promotes construction activity, facilitates technology transfer, and contributes to economic development. Consequently, foreign investment has become an integral component of national growth strategies and the globalisation of property markets.

However, not all foreign investment serves developmental objectives. A distinction must be drawn between productive investment, which contributes to housing supply and infrastructure, and speculative investment, where properties are acquired primarily for capital appreciation rather than occupation or productive use. Large-scale speculative acquisitions, particularly in residential markets, may reduce housing availability, inflate property prices, and undermine affordability for local residents. This has prompted several States to adopt regulatory measures, including restrictions on foreign ownership, vacancy taxes, and additional transaction levies, to discourage speculative practices while preserving access to housing.

The legal regulation of foreign investment is shaped by both domestic laws and international economic obligations. States are often parties to Bilateral Investment Treaties (BITs), investment chapters in Free Trade Agreements (FTAs), and other international investment agreements that guarantee foreign investors standards such as fair and equitable treatment, protection against unlawful expropriation, and non-discriminatory treatment. While these commitments seek to create a stable and predictable investment climate, they do not entirely deprive states of their sovereign authority to regulate in the public interest.

 

Housing as a Human Right under International Law

The right to adequate housing is firmly incorporated under international human rights law. Article 25(1) of the Universal Declaration of Human Rights (UDHR) safeguards housing as an essential component of an adequate standard of living, while Article 11(1) of the International Covenant on Economic, Social and Cultural Rights (ICESCR) obliges States to progressively realise the right to adequate housing through appropriate legislative and policy measures.

The normative content of this right was further clarified by the Committee on Economic, Social and Cultural Rights (CESCR) in General Comment No. 4 (1991), which entails that adequate housing encompasses legal security of tenure, affordability, habitability, accessibility, availability of essential services, suitable location, and cultural adequacy. The Committee further observed that housing costs should not compromise the enjoyment of other fundamental rights.

International human rights law also imposes positive obligations upon States to respect, protect, and fulfil the right to housing. This includes protecting individuals from practices that unnecessarily restrict access to affordable housing. Consequently, where speculative investment significantly contributes to housing unaffordability or market exclusion, states may adopt proportionate regulatory measures to safeguard the public interest. Thus, the right to housing constitutes not merely a social policy objective but a binding legal consideration that must be balanced against obligations arising under international investment law.

International Investment Law and the State’s Right to Regulate

International investment agreements protect foreign investors by prescribing minimum standards of treatment. Although the precise obligations vary across treaties, the following protections are commonly recognised:

• Fair and Equitable Treatment (FET)— Protection against arbitrary, unreasonable, or bad-faith governmental measures.
• National Treatment— Foreign investors should not be treated less favourably than similarly situated domestic investors.
• Most-Favoured-Nation (MFN) Treatment— Foreign investors must receive treatment no less favourable than that accorded to investors from any third State.
• Protection against Expropriation— States may not directly or indirectly expropriate investments without satisfying the applicable treaty requirements, including public purpose, due process, non-discrimination, and compensation where required.

These protections, however, are not absolute. International investment law recognises the State’s inherent right to regulate in pursuit of legitimate public objectives. Under the Police Powers Doctrine, bona fide, non-discriminatory regulations enacted for public welfare do not ordinarily amount to treaty violations merely because they reduce the value or profitability of an investment.

The legality of such measures, however, depends upon their design and implementation. Investment tribunals generally assess whether a regulation is proportionate, non-arbitrary, transparent, and applied without unjustifiable discrimination. Consequently, the central legal issue is not whether States possess the authority to regulate foreign investment, but whether anti-speculation measures can satisfy these standards while simultaneously fulfilling the State’s obligation to protect the right to adequate housing.

 

1. Regulating Real Estate Speculation: When Does Regulation Become Treaty-Inconsistent?

The mere fact that a regulatory measure affects the value of a foreign investment does not, by itself, establish a breach of an international investment agreement. Investment tribunals have consistently distinguished between legitimate exercises of sovereign regulatory authority and measures that are arbitrary, discriminatory, or disproportionate. Accordingly, anti-speculation measures adopted to address housing affordability must be assessed on the basis of their legality rather than their economic impact.

In determining treaty compliance, the following considerations assume particular significance:

• The measure should pursue a recognised public interest, such as ensuring housing affordability or preventing market distortion.
• Comparable domestic and foreign investors should be treated alike unless differential treatment is objectively justified.
• The restriction imposed should bear a reasonable relationship to the objective pursued and should not be excessive.
• Regulatory measures should be adopted through a clear, predictable, and legally established process.
• The measure should genuinely seek to advance a public objective and not serve as a disguised restriction on foreign investment.

Applying these principles, measures such as vacancy taxes, restrictions on bulk acquisitions of residential property, or additional levies on speculative transactions are not inherently inconsistent with international investment law. Their legality depends upon whether they are enacted in a non-arbitrary manner, are proportionate to the public interest sought to be protected, and remain consistent with the State’s treaty obligations. Thus, international investment law does not prohibit regulation of speculative foreign investment; it requires that such regulation be exercised within the limits of legality, fairness, and proportionality.

 

Comparative State Practice on Investment Protection and Housing Rights

Comparative state practice demonstrates an emerging consensus that foreign investment in residential real estate may be regulated where necessary to protect housing affordability. Canada enacted the Prohibition on the Purchase of Residential Property by Non-Canadians Act, 2022, temporarily restricting the acquisition of certain residential properties by non-Canadians in response to housing affordability concerns. New Zealand, through the Overseas Investment Amendment Act 2018, largely prohibited foreign purchasers from acquiring existing residential homes while continuing to permit investment that contributes to new housing supply. Similarly, Singapore imposes an Additional Buyer’s Stamp Duty (ABSD) at higher rates on foreign purchasers, whereas Australia subjects foreign acquisitions of residential property to a statutory approval regime under the Foreign Acquisitions and Takeovers Act 1975, encouraging investment in newly constructed dwellings rather than existing housing stock. These measures recognise housing affordability as a legitimate public interest.

These jurisdictions have not imposed blanket prohibitions on foreign investment. Instead, they regulate speculative acquisitions through targeted measures while allowing productive investment. Their frameworks rely on clear legislative objectives, transparent implementation, and proportionate restrictions aimed at improving housing affordability. This approach is consistent with international investment law, which permits States to regulate for legitimate public welfare objectives, provided such measures are adopted in good faith, are non-discriminatory where applicable, and remain proportionate. Comparative practice therefore demonstrates that housing affordability can be protected without breaching international investment obligations.

 

India’s Regulatory Approach

India’s legal framework seeks to balance investment promotion with the State’s constitutional and international obligations. Foreign investment in the construction and real estate sector is regulated primarily through the Foreign Exchange Management Act, 1999 (FEMA), the Consolidated FDI Policy, and allied regulations issued by the Reserve Bank of India. Simultaneously, India’s 2016 Model Bilateral Investment Treaty (Model BIT) marks a significant shift from earlier investment treaties by expressly affirming the State’s regulatory autonomy. Article 2.4 of the Model BIT excludes matters relating to government procurement, subsidies, taxation (subject to exceptions), and certain regulatory measures, while Article 32 affirms that Parties retain the right to regulate investments in pursuit of legitimate public welfare objectives. This reflects India’s evolving treaty practice, which accords greater deference to sovereign regulatory powers than many first-generation BITs.

At the constitutional level, although the right to housing is not expressly guaranteed, the Supreme Court has consistently interpreted it as an integral facet of Article 21. The judiciary has also uphold that developmental policies must remain consistent with constitutional values of dignity and social justice.

 

What Have the Courts Said?

In Olga Tellis v. Bombay Municipal Corporation, the Supreme Court held that the right to livelihood forms part of Article 21 and observed that eviction without a just and reasonable procedure directly affects an individual’s ability to secure shelter and livelihood. The decision laid the constitutional foundation for provides for housing as an element of the right to life.

In Chameli Singh v. State of Uttar Pradesh, the Court expressly held that the right to shelter is a fundamental right under Article 21. It observed that adequate shelter is indispensable to human dignity and encompasses access to civic amenities necessary for meaningful living rather than mere physical protection.

In Ahmedabad Municipal Corporation v. Nawab Khan Gulab Khan, while preserving the authority of the State to remove encroachments in accordance with law, the Supreme Court said that rehabilitation and humane treatment remain relevant constitutional considerations. The judgment reaffirmed that administrative action affecting shelter must satisfy standards of fairness and reasonableness.

These decisions indicate that housing occupies a protected constitutional position in India. Consequently, regulatory measures aimed at preventing speculative distortions in the housing market would not be viewed solely through the lens of investment promotion but also against the State’s constitutional obligation to secure dignified living conditions. Read alongside the regulatory flexibility embedded in India’s Model BIT, the existing legal framework provides sufficient scope for adopting carefully designed, proportionate, and non-arbitrary measures to address speculative foreign investment while remaining broadly consistent with India’s international economic commitments.

 

A Rights-Compatible Investment Framework

Reconciling foreign investment with the protection of housing rights requires a regulatory framework that safeguards both investor confidence and the State’s responsibility to ensure affordable housing. Rather than imposing absolute restrictions, the emphasis should be on adopting legally sustainable measures that are transparent, proportionate, and consistent with international investment obligations. The following reforms may assist in achieving this balance:

• Incorporate explicit right-to-regulate clauses in future Bilateral Investment Treaties (BITs), affirming the State’s authority to adopt bona fide measures for housing affordability, urban planning, and social welfare.
• Distinguish productive investment from speculative acquisition by encouraging investment in new housing projects while regulating acquisitions that merely inflate property values without expanding housing supply.
• Adopt objective and non-discriminatory regulatory measures, such as vacancy taxes, anti-flipping rules, or restrictions on bulk purchases, ensuring that similarly situated investors are treated equally and that any differential treatment is supported by a legitimate public purpose.
• Apply the principle of proportionality while framing regulatory measures. Restrictions should be necessary to achieve the intended public objective and should not impose excessive or arbitrary burdens on investors.
• Strengthen transparency and regulatory certainty by clearly defining the scope, duration, and implementation of anti-speculation measures. Predictable legal frameworks minimise investment disputes while preserving regulatory effectiveness.
• Integrate human rights considerations into housing governance by assessing the likely impact of major real estate policies on housing affordability and accessibility before their implementation.
• Encourage treaty interpretation consistent with sustainable development and enshrine that investment protection and public welfare are complementary objectives rather than competing interests. Modern investment jurisprudence increasingly supports this approach by acknowledging the legitimacy of bona fide public-interest regulation.

A rights-compatible investment framework does not require States to choose between economic growth and housing protection. Instead, it requires regulations that are legally justified, proportionate, and directed towards a legitimate public purpose. This strengthens both the credibility of the investment regime and the state’s capacity to fulfil its obligation of ensuring access to adequate housing.

 

Conclusion

The increasing participation of foreign investors in real estate requires States to balance two legitimate legal interests i.e. protecting investment and ensuring access to adequate housing. International investment law does not prohibit States from regulating speculative investment; it requires that such regulation be lawful, proportionate, transparent, and non-discriminatory. Comparative state practice demonstrates that housing affordability can be protected without disregarding international economic obligations. As the legal maxim salus populi suprema lex esto (the welfare of the people shall be the supreme law) suggests, measures adopted in the genuine public interest deserve legal recognition, provided they conform to treaty obligations and the rule of law. A balanced regulatory framework is therefore essential to promote sustainable investment while safeguarding housing as a fundamental human right.
