UBS Global Real Estate Bubble Index

June 2016 | 3 min read

The UBS Global Real Estate Bubble Index is designed to track the risk of housing bubbles in global financial centers.

House prices of the cities within the bubble risk zone have increased by almost 50% on average since 2011. In the other financial centers, prices have only risen by less than 15%. This gap is out of proportion to differences in local economic growth and inflation rates.

Vancouver tops the index in 2016. Bubble risk also seems eminent in London, Stockholm, Sydney, Munich and Hong Kong. Deviations from the long-term norm point to overvalued housing markets in San Francisco and Amsterdam. Valuations are also stretched, but to a lesser degree, in Zurich, Paris, Geneva, Tokyo and Frankfurt. In contrast, Singapore, Boston, New York and Milan are fairly valued, while Chicago’s housing market remains undervalued relative to its own history.

Elevated risk of a price correction

The discrepancies have emerged out of a mix of optimistic expectations, capital inflows from abroad and loose monetary policy. The weak economic foundations of the latest price boom make the housing markets in those cities vulnerable. A change in macroeconomic momentum, a shift in investor sentiment or a major supply increase could trigger a rapid decline in house prices. Investors in overvalued markets should not expect real price appreciation in the medium to long run.
