Buoyed by low interest rates for the last decade, many property markets have seen substantial price growth since 2010. Experts warned that real estate bubbles—in which the price of assets moved up far beyond their intrinsic value—were forming.

The UBS Global Real Estate Bubble Index analyzes the real estate market of 25 major cities across the globe and assigns them a score between -0.5 to 2.0 to convey bubble risk. The higher the score, the more imbalanced the market is, with those above 1.5 in “bubble-risk” territory.
