An exploratory study on BreathePLAN in Housing Studies: for Housing Studies students

An exploratory study on BreathePLAN in Housing Studies: for Housing Studies students (information from perplexity.ai)

My question 1: "What is BreathePLAN all about with reference to the Hong Kong Housing Market?"

The reply: "BreathePLAN in reference to the Hong Kong housing market is a mortgage insurance scheme launched by the Hong Kong Mortgage Corporation, designed to address the affordability crisis caused by long-term high property prices. It is a financial innovation that breaks the traditional mortgage into a "developer second mortgage" and a "bank first mortgage," allowing buyers to initially pay a low interest rate (1.68%) for the first three years. This creates the illusion of "painless home buying" by reducing the average initial mortgage burden rate from about 65% to 35%.

However, this comes with significant risks: starting from the fourth year, buyers must substantially reduce their mortgage balance, often requiring them to save amounts far exceeding typical household incomes. This structure effectively transfers much of the risk to consumers, creating a potential debt trap.

The widespread adoption of BreathePLAN (used by as much as 78% of new projects in 2023) has distorted the housing market ecosystem by encouraging developers to adjust pricing strategically around the plan’s features. This credit expansion has made the market heavily dependent on this financing model, and with the repayment period starting in 2025, an estimated 15% of buyers might default on their loans, drawing comparisons to a subprime mortgage crisis.

Moreover, the BreathePLAN has become emblematic of social and generational tensions in Hong Kong, especially among young people who feel trapped in a high-priced housing market. It has sparked broad societal debate as it highlights deep structural and regulatory flaws, including regulatory gaps and the circumvention of banking lending restrictions, leading to excessive borrowing and information asymmetry between developers and buyers.

In summary, BreathePLAN is a mortgage financial product aimed at making home buying in Hong Kong more accessible under current market conditions, but it carries hidden risks and has contributed to market distortions and social tensions related to housing affordability."

My question 2: "What are the theories to study this topic?"

The reply: "To study the topic of BreathePLAN and its effects on the Hong Kong housing market, several theoretical frameworks and economic models are commonly applied:

1. Housing Market Fundamentals and Price Dynamics
   This approach analyzes how fundamental variables such as economic activity, interest rates, household growth, and supply constraints influence property prices and market volatility. It also incorporates the role of speculative bubbles and market sentiment ("animal spirits") which can cause prices to deviate from fundamentals, a relevant consideration given the distortions caused by BreathePLAN financing.

2. Housing Ladder Effect
   This theory explains how increases in housing equity at lower tiers encourage trading up the housing ladder, leading to increased market turnover and price buoyancy. It helps understand behavioral responses of buyers and sellers in a segmented but interconnected market, particularly under policies like BreathePLAN that affect financing and ownership patterns.

3. Game Theory in Real Estate Market
   Game theory models interactions among key players such as developers and the government. In Hong Kong's oligopolistic land auction environment, developers’ strategies around pricing and government land lease policies shape the high housing prices. This framework elucidates strategic behaviors, incentives, and equilibrium outcomes that can explain persistent affordability issues intensified by credit innovations like BreathePLAN.

4. Credit and Debt Cycle Theories
   While less explicitly mentioned in the search results, studying financial products like BreathePLAN benefits from analyzing credit cycles, debt traps, and risk transfer between borrowers and lenders. These concepts explain how innovations in mortgage structure may create hidden vulnerabilities and systemic risks akin to subprime mortgage crises.

5. Market Sentiment and Behavioral Economics
   Including factors such as buyer optimism, fear, or misinformation, these theories contextualize how the perception of "painless home buying" under BreathePLAN affects demand and risk-taking behavior.

In sum, interdisciplinary approaches combining fundamental market analysis, behavioral insights, strategic interactions, and financial risk assessment provide robust theoretical lenses to study BreathePLAN and its impacts on Hong Kong’s housing market."

My question 3: "What are the research gaps and research issues on this topic?"

The reply: "Current research gaps and issues regarding the topic of BreathePLAN and its impact on the Hong Kong housing market primarily arise from its novelty, complexity, and systemic effects. While direct dedicated research specific to BreathePLAN might be still emerging, the following research gaps and issues can be identified based on the characteristics and concerns raised around this financial product:

1. Long-Term Financial Risk Assessment
   There is a gap in comprehensive longitudinal studies quantifying the long-term default risk and financial distress among BreathePLAN borrowers, especially as the repayment phase intensifies starting around 2025. More empirical analyses are needed on how many borrowers will actually face debt traps or defaults and under what economic or policy scenarios.

2. Market Distortion and Pricing Dynamics
   Research is needed to better understand how the widespread use of BreathePLAN distorts housing prices and developer behavior. This includes modeling strategic pricing responses by developers aware of the credit scheme and exploring the impacts on housing supply-demand dynamics and price bubbles.

3. Behavioral and Social Impact Analyses
   There is limited research on buyer behavior under BreathePLAN, especially regarding risk perception, optimism bias about mortgage affordability, and the social consequences such as generational tensions and consumer dissatisfaction linked to housing affordability.

4. Regulatory Gaps and Policy Effectiveness
   Identifying specific regulatory loopholes that BreathePLAN exploits or circumvents and evaluating the effectiveness of current policy measures in mitigating excessive risk transfer to borrowers is an important research area. This includes assessing whether Hong Kong’s mortgage lending regulations need reform concerning innovative mortgage products like BreathePLAN.

5. Comparative and Theoretical Framework Development
   More development of interdisciplinary theoretical models combining credit risk, game theory in real estate, and behavioral economics tailored to the Hong Kong context would help better frame and predict outcomes related to schemes like BreathePLAN.

6. Data Transparency and Information Asymmetry
   Investigating how information asymmetry between developers, lenders, and buyers affects market outcomes and borrower decision-making processes under BreathePLAN is another gap. Transparency improvements might be required to allow buyers to better understand the real costs and risks.

7. Macro-Financial Stability Implications
   Research is needed on whether the growth of BreathePLAN-style financing could pose systemic risks to Hong Kong’s financial stability, akin to subprime mortgage crises elsewhere, especially under adverse economic shocks.

In summary, the research field on BreathePLAN and its Hong Kong housing market impacts requires multi-disciplinary empirical and theoretical studies focusing on financial risk, market dynamics, behavioral effects, regulation, and systemic stability. These gaps present opportunities for academic inquiry and policy analysis as the repayment phase and market consequences unfold around 2025 onwards."

My question 4: "What are the Hong Kong public media-reported issues on this topic?"

The reply: "Hong Kong public media have reported several issues relating to the housing market in 2025, which are relevant to understanding the context in which BreathePLAN operates, though direct explicit mentions of BreathePLAN's controversies in recent media are limited. Key issues include:

• Housing Affordability and Market Conditions: Reports highlight ongoing challenges with oversupply in both residential and commercial sectors amid economic uncertainties. Residential property prices, including mass and luxury segments, have experienced declines of around 5% expected in 2025 after a 6.8% drop in 2024, signaling continuing price pressure on home buyers.

• Market Activity and Transaction Volume: Despite price declines, transaction volumes have shown some growth, with about 60,000 residential transactions expected for 2025, reflecting about 10% growth year-on-year. This is partly driven by lower mortgage borrowing rates and removal of market cooling measures, encouraging some tenant-to-owner conversions.

• Risks for Developers and Oversupply: The market faces margin pressures due to developers holding projects bought at higher land prices, with a high inventory relative to sales, leading to selective land acquisitions and pressure to destock. Oversupply issues contribute to price and rental adjustments.

• Mortgage and Financing Environment: The mortgage lending environment is competitive with fluctuating interest rates such as Hibor (Hong Kong Interbank Offered Rate), which influences the affordability and overall demand dynamics. Lower rates have temporarily supported buying activity.

• Social and Economic Context: Media coverage underscores the persistent chronic housing shortage and affordability challenges, which have socio-economic implications especially for young homebuyers. The dynamics of demand, supply, and financing continue to affect market sentiment.

While these media narratives indicate a cautious market environment with structural pressures, direct public media reports rarely name BreathePLAN specifically as a contentious issue. The broader context of housing affordability, credit conditions, and developer strategies indirectly relate to themes of financial innovation and risks exemplified by BreathePLAN.

Thus, public media mainly focuses on systemic housing market challenges, price trends, financing conditions, and developer behavior that set the backdrop for understanding the risks and debates linked to BreathePLAN in Hong Kong."

My question 5: "Propose 4 related research objectives and 2 related research issues on this topic for a part-time Housing Studies dissertation project with a duration of 4 months. Also suggest 2 primary research methods and 1 secondary research method for this project based on pragmatism."

The reply: "For a part-time Housing Studies dissertation project lasting 4 months on the topic of BreathePLAN and the Hong Kong housing market, based on pragmatism as a research philosophy (which values practical solutions and integrates mixed methods), I propose the following:

Research Objectives

1. Assess the short-to-medium term financial risks faced by BreathePLAN buyers, particularly focusing on their repayment challenges starting from 2025.
   (This objective addresses empirical risk analysis and buyer financial experiences.)

2. Investigate how BreathePLAN influences housing price dynamics and developer pricing strategies in the Hong Kong market.
   (This examines market distortions and strategic responses by developers.)

3. Explore the perceptions, behaviors, and risk understanding of homebuyers using BreathePLAN, especially among younger generations.
   (Focus on buyer psychology and social impact under the scheme.)

4. Evaluate the effectiveness of regulatory frameworks and policy responses in managing the risks associated with BreathePLAN.
   (This assesses governance, regulatory gaps, and policy adequacy.)

Related Research Issues

• Information asymmetry and transparency challenges between developers, lenders, and buyers under BreathePLAN.
  (Buyers might not fully understand the financial risks due to complex product design and uneven information sharing.)

• Potential systemic risks to Hong Kong’s housing market and financial stability arising from widespread reliance on BreathePLAN financing.
  (Risk of defaults creating broader market instability as repayment commences.)

Primary Research Methods (Pragmatic Mixed Approach)

1. Semi-structured interviews with affected homebuyers and mortgage experts to gather qualitative insights on buyer perceptions, financial challenges, and risk awareness.
   (Captures rich, contextualized data relevant to real-world experiences.)

2. Survey questionnaire targeting a broader sample of BreathePLAN users to quantify repayment difficulties, risk perceptions, and demographic patterns.
   (Allows for statistical analysis and generalizable findings.)

Secondary Research Method

• Document analysis of government reports, media coverage, developer pricing data, and policy papers related to BreathePLAN and Hong Kong’s housing market.
  (Provides background, context, and triangulates findings from primary data with existing knowledge.)

By combining qualitative and quantitative methods under pragmatism, this project can effectively address practical housing affordability and financial risk issues posed by BreathePLAN within a limited time frame. This mixed method approach leverages real-world data and theoretical understanding to support actionable insights in housing policy and finance."

My question 6: "Comment on the originality, academic and practical values of this study. Also comment on the research ethics issues involved in this study."

The reply: "The proposed study on BreathePLAN and its impact on the Hong Kong housing market demonstrates strong originality, academic value, practical significance, and raises important research ethics considerations:

Originality

• BreathePLAN is a relatively new and unique mortgage insurance scheme affecting a distinctive and complex housing market scenario in Hong Kong. Research specifically focused on this financial innovation, especially its systemic risks starting from 2025, fills a clear gap in academic literature, as existing studies have not fully explored this novel product’s long-term impacts, behavioral aspects, and regulatory challenges.

• The study’s interdisciplinary approach combining financial risk assessment, market dynamics, behavioral economics, and regulatory evaluation is also innovative because it transcends traditional siloed housing market analyses, addressing a multifaceted socio-economic issue in a timely manner.

Academic Value

• The project advances theoretical understanding by integrating housing economics, game theory, credit risk cycles, and behavioral insights applied to Hong Kong’s unique housing finance context.

• Empirical findings from mixed qualitative and quantitative methods can contribute to academic debates on mortgage innovations, housing affordability crises, and credit risk in high-priced real estate markets.

• It offers a case study that may have relevance to other global cities facing similar housing affordability and mortgage debt challenges, thereby extending its academic impact beyond Hong Kong.

Practical Value

• The study provides critical evidence-based insights on how financial products like BreathePLAN affect borrower vulnerability, market prices, and systemic financial risks, which can directly inform policymakers, regulators, housing developers, lenders, and consumer protection bodies.

• Understanding buyer perceptions and regulatory gaps can guide the design of safer mortgage products, enhanced market transparency, and targeted policy interventions to mitigate debt traps and social tensions related to housing affordability.

• The findings may help anticipate and prevent potential market destabilization and housing crises associated with widespread credit innovations.

Research Ethics Issues

• Informed Consent and Transparency: Interview and survey participants (homebuyers, mortgage experts) must clearly understand the study’s purpose, data use, and voluntary nature to provide informed consent ethically. Given the personal financial nature, ensuring comfort and confidentiality is vital.

• Confidentiality and Data Protection: Protecting respondents' financial information and identities is crucial since mortgage and housing finance data can be highly sensitive. Anonymization and secure data handling protocols are necessary.

• Minimizing Harm and Risk: The study should avoid causing distress or undue pressure on participants, especially those facing financial difficulties or defaults. Researchers must be sensitive to the emotional and social implications of housing insecurity.

• Avoiding Conflicts of Interest and Bias: Transparency about researcher affiliations and funding sources is important to uphold integrity and trustworthiness. The research design should minimize bias, especially in interpreting policy or developer-related issues.

• Ethical Approval: The study should obtain institutional ethical clearance to ensure compliance with standards such as the Hong Kong Principles for Research Integrity, which emphasize trustworthy, responsible research conduct.

Overall, the study’s originality and comprehensive scope offer valuable academic and practical contributions to understanding and managing a critical and evolving housing finance challenge in Hong Kong, while its ethical rigor ensures responsible treatment of sensitive participant data and impacts. This aligns with the international quality standards and research excellence promoted by Hong Kong’s academic institutions."
