The World’s Biggest Real Estate Bubbles in 2021
Ranked: The World’s Biggest Real Estate Bubbles in 2021
Identifying real estate bubbles is a tricky business. After all, even though many of us “know a bubble when we see it”, we don’t have tangible proof of a bubble until it actually bursts.
And by then, it’s too late.
The map above, based on data from the Real Estate Bubble Index by UBS, serves as an early warning system, evaluating 25 global cities and scoring them based on their bubble risk.
Reading the Signs
Bubbles are hard to distinguish in real-time as investors must judge whether a market’s pricing accurately reflects what will happen in the future. Even so, there are some signs to watch out for.
As one example, a decoupling of prices from local incomes and rents is a common red flag. As well, imbalances in the real economy, such as excessive construction activity and lending can signal a bubble in the making.
With this in mind, which global markets are exhibiting the most bubble risk?
The Geography of Real Estate Bubbles
Europe is home to a number of cities that have extreme bubble risk, with Frankfurt topping the list this year. Germany’s financial hub has seen real home prices rise by 10% per year on average since 2016—the highest rate of all cities evaluated.
Two Canadian cities also find themselves in bubble territory: Toronto and Vancouver. In the former, nearly 30% of purchases in 2021 went to buyers with multiple properties, showing that real estate investment is alive and well. Despite efforts to cool down these hot urban markets, Canadian markets have rebounded and continued their march upward. In fact, over the past three decades, residential home prices in Canada grew at the fastest rates in the G7.
Despite civil unrest and unease over new policies, Hong Kong still has the second highest score in this index. Meanwhile, Dubai is listed as “undervalued” and is the only city in the index with a negative score. Residential prices have trended down for the past six years and are now down nearly 40% from 2014 levels.
Note: The Real Estate Bubble Index does not currently include cities in Mainland China.
Trending Ever Upward
Overheated markets are nothing new, though the COVID-19 pandemic has changed the dynamic of real estate markets.
For years, house price appreciation in city centers was all but guaranteed as construction boomed and people were eager to live an urban lifestyle. Remote work options and office downsizing is changing the value equation for many, and as a result, housing prices in non-urban areas increased faster than in cities for the first time since the 1990s.
Even so, these changing priorities haven’t deflated the real estate market in the world’s global cities. Below are growth rates for 2021 so far, and how that compares to the last five years.
Overall, prices have been trending upward almost everywhere. All but four of the cities above—Milan, Paris, New York, and San Francisco—have had positive growth year-on-year.
Even as real estate bubbles continue to grow, there is an element of uncertainty. Debt-to-income ratios continue to rise, and lending standards, which were relaxed during the pandemic, are tightening once again. Add in the societal shifts occurring right now, and predicting the future of these markets becomes more difficult.
In the short term, we may see what UBS calls “the era of urban outperformance” come to an end.

Visualizing the Rise of the U.S. Dollar Since the 19th Century
As the world’s reserve currency, the U.S. dollar made up 58.4% of foreign reserves held by central banks in 2022, falling near 25-year lows.
Today, emerging countries are slowly decoupling from the greenback, with foreign reserves shifting to currencies like the Chinese yuan.
At the same time, the steep appreciation of the U.S. dollar is leading countries to sell their U.S. foreign reserves to help prop up their currencies, in turn buying currencies such as the Australian and Canadian dollars to help generate higher yields.
The above animated graphic from James Eagle shows the rapid ascent of the U.S. dollar over the last century, and its gradual decline in recent years.
Dollar Dominance: A Brief History
In 1944, the U.S. dollar became the world’s reserve currency under the Bretton Woods Agreement. Over the first half of the century, the U.S. ran budget surpluses while increasing trade and economic ties with war-torn countries, expanding its influence as the world’s store of value.
Later through the 1960s, the U.S. dollar share of global foreign reserves rapidly increased as political allies stockpiled the dollar.
By 2000, dollar dominance hit a peak of 71% of global reserves. With the creation of the European Union a year earlier, countries such as China began increasing the share of euros in reserves. Between 2000 and 2005, the share of the dollar in China’s foreign exchange reserves fell by an estimated 15 percentage points.
The dollar began a long rally after the global financial crisis, which drove central banks to cut their dollar reserves to help bolster their currencies.
Fast-forward to today, and dollar reserves have fallen roughly 13 percentage points from their historical peak.
The State of the World’s Reserve Currency
In 2022, 16% of Russia’s export transactions were in yuan, up from almost nothing before the war. Brazil and Argentina have also begun adopting the Chinese currency for trade or reserve purposes. Still, the U.S. dollar makes up 80% of Brazil’s reserves.
Yet while the U.S. dollar has decreased in share of foreign reserves, it still has an immense influence in the world economy.
The majority of trade is invoiced in the U.S. dollar globally, a trend that has stayed fairly consistent over many decades. Between 1999-2019, 74% of trade in Asia was invoiced in dollars and in the Americas, it made up 96% of all invoicing.
Furthermore, almost 90% of foreign exchange transactions involve the U.S. dollar thanks to its liquidity.
However, countries are increasingly finding alternative options than the dollar. Today, Western businesses have begun settling trade with China in renminbi. Looking further ahead, digital currencies could provide options that don’t include the U.S. dollar.
Even more so, if the U.S. share of global GDP continues to shrink, the shift to a multipolar system could progress over this century.
