Understanding the UBS Index
Valuation.
Risk.
Not a crash clock.
The UBS Index combines valuation warning signals. It shows where purchase prices are particularly stretched relative to rents and incomes, but it does not provide a forecast for the timing or scale of a correction.
UrbanHome market analysis
01
What does the 2026 UBS Real Estate Bubble Index say?
The UBS Global Real Estate Bubble Index published on 22 September 2026 analyses 23 selected international cities. Zurich reaches 1.69 index points, ahead of Tokyo (1.54) and Geneva (1.12). “Highest risk” here means: among these 23 cities, not among every property market in the world.
02
Is Zurich in a property bubble – and is a crash imminent?
A bubble index combines warning signals such as the relationship between prices, rents and incomes. It neither proves that a speculative bubble has already burst nor predicts a date or a specific magnitude for future price declines. High valuations can also normalise through falling purchase prices, rising incomes and rents or several years of nominal price stagnation.
03
Why does the national UBS Index not contradict this?
The international index focuses on selected cities and classifies Zurich as high risk. The separate UBS Swiss Real Estate Bubble Index rates the Swiss owner-occupied housing market at 0.72 points in the second quarter of 2026, corresponding to moderate risk; over the same period, Swiss home prices were 3.6 percent higher than a year earlier. The results should not be treated as directly comparable because their geographical scope and calculation methods differ.
Zurich property market
Why do apartments and houses in Zurich remain expensive?
Housing in attractive urban locations is scarce, and new homes cannot be created overnight. Low financing costs and demand from households with high incomes or substantial equity support the purchase market. On the other hand, Zurich is sensitive to sharply rising mortgage rates, weaker employment and immigration, or a larger supply of comparable properties for sale.
01
Supply
Housing remains scarce
New homes cannot be created overnight in attractive urban areas. Limited supply supports prices.
02
Financing
Low costs can provide support
Low financing costs improve affordability and can provide additional support to the purchase market.
03
Strong purchasing power
Households with high incomes or substantial equity can support demand for scarce properties.
04
Sensitive to headwinds
Rising mortgage rates, weaker employment or immigration and more properties for sale can put pressure on the market.
Buy or rent
Buy or rent: What do 46 annual rents mean?
According to UBS, the purchase price of a Zurich apartment corresponds to roughly 46 annual rents for a comparable property. On a purely mathematical basis, a purchase price of CHF 1,000,000 would therefore correspond to annual rent of around CHF 21,740 or monthly rent of around CHF 1,810. This is only an illustration of the ratio, not an actual listing price or a complete cost comparison: interest, amortisation, maintenance, taxes, the opportunity cost of equity and transaction costs are not included.

Interest, amortisation, maintenance, taxes, the opportunity cost of equity and transaction costs are not included in this simple ratio calculation.
Possible developments
How could property prices develop in 2026 and beyond?
These are scenarios, not forecasts or probabilities. The development of an individual property depends, among other things, on its micro-location, condition, energy efficiency, price level and financing.
01
Scenario
Stable or rising prices
Scarce supply and strong purchasing power support properties in good locations.
02
Scenario
Sideways market
Purchase prices stagnate while incomes and rents gradually catch up over the years.
03
Price correction
Higher interest rates, weaker demand or an increase in properties for sale could put downward pressure on purchase prices.
Swiss financing

The key mortgage rules.
For owner-occupied residential property, banks generally require around 20 percent equity. At least 10 percent of the lending value must come from funds that are not withdrawn or pledged from occupational pension savings (2nd pillar). For new financing, the part of the mortgage above two thirds of the lending value must generally be amortised within no more than 15 years. Banks assess affordability using long-term imputed interest rates and individual criteria; a low current mortgage rate alone is not sufficient.

Key takeaway
Summary
Conclusion: Zurich is highly valued according to the 2026 UBS city index, but this does not imply that an immediate price crash is imminent. Anyone planning to buy, sell or rent should assess local comparable properties, financing conditions and their own time horizon rather than treating a risk indicator as a certain price forecast.

Questions & answers
Zurich has the highest value in the 2026 UBS Index among the 23 cities analysed. “Worldwide” in this context does not mean that every city in the world was assessed.
No. The risk index measures valuation imbalances and does not predict a specific price crash or date.
That remains uncertain. Scarcity and low financing costs can support prices, while higher interest rates and weaker demand can put pressure on them. The index alone does not answer the forecasting question.
The separate Swiss UBS Index examines the nationwide market and uses different model components. The valuation of one major urban market cannot be transferred one-to-one to the whole of Switzerland.
For owner-occupied property, around 20 percent equity is commonly required. At least 10 percent of the lending value must come from funds outside the second pillar; an individual bank assessment may impose stricter requirements.
