Zurich and Tokyo Identified as High-Risk Markets in 2026 Global Real Estate Bubble Index

A new report released on September 22, 2026, by the investment bank UBS has identified Zurich and Tokyo as the cities facing the highest risk of a housing bubble. The UBS Global Real Estate Bubble Index 2026 analyzed residential property prices across 23 major cities worldwide to assess market stability. The findings suggest that these two urban centers are currently experiencing significant valuation pressures that could impact future market health. This annual study serves as a key indicator for investors and policymakers monitoring global real estate trends. The inclusion of cities like Lisbon and Seoul in this year's sample provided a broader view of how different regions are managing housing demand. According to the report, Zurich’s property market remains exceptionally tight, with valuations increasingly dependent on low interest rates. Analysts noted that the Swiss city has seen sustained price growth that may not be fully supported by local economic fundamentals. Meanwhile, the Tokyo market is showing signs that its long-standing boom may be approaching its limits. Rising prices for new homes in the Japanese capital have made mortgage lending more complex for financial institutions. The report highlights that prime markets in these cities are diverging from broader housing trends, largely due to intense interest from wealthy individuals and international investors. This influx of capital has helped drive prices upward, even as affordability becomes a growing concern for local residents. In contrast to the high-risk status of Zurich and Tokyo, other major cities have seen their risk profiles shift. Miami, which held the top position in the previous two editions of the index, has moved into the elevated-risk category. It now shares this classification with cities such as Dubai, Seoul, Geneva, and Lisbon. These shifts reflect the complex and varied nature of global real estate markets as they navigate changing economic conditions. The report emphasizes that while some markets are cooling, others continue to face significant upward pressure on prices. Experts suggest that the divergence between prime real estate and the wider market is a defining feature of the current landscape. As interest rates and economic policies evolve, the stability of these high-risk markets will remain a focal point for global financial observers. The findings underscore the importance of careful monitoring for those involved in property investment and urban development.
