The UBS Global Real Estate Bubble Index is designed to track the risk of housing bubbles in global financial centers.
According to the UBS Global Real Estate Bubble Index, the bubble risk in select world cities has increased significantly over the last five years. Real house prices of those metropolises within the bubble-risk zone have climbed by almost 50% on average since 2011. In the other financial centers, prices have risen by roughly 15%. This gap is grossly out of proportion to the differences in local economic growth and inflation rates.
