These Global Cities Show the Highest Real Estate Bubble Risk
Housing bubbles are a tricky phenomenon. As a market gathers steam and prices increase, it remains a matter of debate whether that market is overvalued and flooded with speculation, or it’s simply experiencing robust demand.
Of course, once a bubble bursts, it’s all obvious in hindsight.
One common red flag is when prices decouple from local incomes and rents. As well, imbalances in the real economy, such as excessive construction activity and lending can signal a bubble in the making.
The map above, based on data from the Real Estate Bubble Index by UBS, examines 25 global cities, scoring them based on their bubble risk.
Overinflated Markets
In the 2022 edition of the Real Estate Bubble Index, nine of the cities covered were classified as having extreme bubble risk (1.5 or higher score).
Rank | Risk Category | City | Bubble Index Score |
---|---|---|---|
#1 | 🔴 | 🇨🇦 Toronto | 2.24 |
#2 | 🔴 | 🇩🇪 Frankfurt | 2.21 |
#3 | 🔴 | 🇨🇭 Zurich | 1.81 |
#4 | 🔴 | 🇩🇪 Munich | 1.80 |
#5 | 🔴 | 🇭🇰 Hong Kong | 1.71 |
#6 | 🔴 | 🇨🇦 Vancouver | 1.70 |
#7 | 🔴 | 🇳🇱 Amsterdam | 1.62 |
#8 | 🔴 | 🇮🇱 Tel Aviv | 1.59 |
#9 | 🔴 | 🇯🇵 Tokyo | 1.56 |

Canada’s largest city finds itself at the top of a ranking no city wants to end up on. Toronto’s home prices have been rising steadily for years now, and many, including UBS, believe that the city is now firmly in bubble territory.
Vancouver also finds itself in a similar position. Both Canadian cities have a high quality of life and have thriving tech industries.
Notably, none of the U.S. cities analyzed find themselves in the most extreme bubble risk category. The closest scoring U.S. city was Miami, which sits firmly in overvalued territory (0.5-1.5 range) with a score of 1.39.
Examining the Trends
In recent years, low interest rates helped push home prices and incomes further apart.
For cities in the bubble risk zone, prices have climbed by an average of 60% in inflation-adjusted terms over the past decade, while rents and real incomes increased by just 12%. And, while COVID-19 briefly put a dent in urban demand, rents in the cities analyzed rose at around the same pace as pre-pandemic times.
As a result, all but three of the cities saw positive price growth over the past year from a nominal price perspective:
U.S. cities occupy a number of spots at the top of this chart. Miami, in particular, is seeing strong internal migration patterns, as well as renewed interest from foreign investors.
Hong Kong experienced the biggest one-year nominal drop of all the cities analyzed. The report notes that since around 2019 Hong Kong “has broadly stagnated as the lack of affordability, economic woes, and pandemic restrictions all took a major toll on demand.”
Prices can’t rise forever. According to UBS, most cities with high valuations, price corrections have already begun, or could be right around the corner.

An Investor’s Guide to Copper in 3 Charts
Explore three key insights into the future of the copper market, from soaring demand to potential supply constraints.

An Investor’s Guide to Copper
Copper is the world’s third-most utilized industrial metal and the linchpin of many clean energy technologies. It forms the vital connections in our electricity networks, grid storage systems, and electric vehicles.
In this graphic, sponsored by iShares, we dig into the forces that are set to shape the future of the copper landscape.
How Much Copper Do We Need?
Copper is poised to experience a remarkable 54% surge in demand from 2022 to 2050.
Here’s a breakdown of the expected demand for copper across clean energy technologies.
Technology | 2022 (kt) | 2050P (kt) |
---|---|---|
Electricity networks | 4364 | 8862 |
Other low emissions power generation | 93.7 | 142.2 |
Solar PV | 756.8 | 1879.8 |
Grid battery storage | 24.6 | 665.2 |
Wind | 453.5 | 1303.3 |
Hydrogen technologies | - | 0.22 |
Electric vehicles | 370 | 3582.9 |
Other uses | 19766 | 22382 |
Copper is vital in renewable energy systems such as wind turbines, solar panels, and electric vehicle batteries because of its high electrical conductivity and durability.
It ensures the effective transmission of electricity and heat, enhancing the overall performance and sustainability of these technologies.
The rising demand for copper in the clean energy sector underscores its critical role in the transition to a greener and more sustainable future.
When Will Copper Demand Exceed Supply?
The burgeoning demand for copper has set the stage for looming supply challenges with a 22% gap predicted by 2031.
Given this metal’s pivotal role in clean energy and technological advancements, innovative mining and processing technologies could hold the key to boosting copper production and meeting the needs of a net-zero future.
Investing in Copper for a Prosperous Future
Investors looking for copper exposure may want to consider an ETF that tracks an index that offers access to companies focused on the exploration and mining of copper.
