Weekly Real Estate News
In brief: The global housing market is no longer moving in one direction. UBS identifies Zurich and Tokyo as the most vulnerable major markets to a potential bubble, even as prices in several Canadian and European cities have already retreated.
The 2026 UBS Global Real Estate Bubble Index, released September 22 and reviewed in WRE News’ latest international coverage sweep, places Zurich first and Tokyo second for bubble risk among 23 cities. The assessment measures valuation imbalances; it does not forecast when or whether a crash will occur.
Miami, which led the previous two editions, moved into the elevated-risk category alongside Dubai, Seoul, Geneva and Lisbon. The report rates New York, San Francisco and London as low risk under its methodology, while Los Angeles, Sydney, Toronto and Vancouver are in the moderate category.
Canada falls while some Asian and European cities surge
UBS found that inflation-adjusted residential prices fell by approximately 10% over the prior year in both Vancouver and Toronto. Seoul, Lisbon, Madrid and Hong Kong moved in the opposite direction, recording real price gains of roughly 10%.
Zurich’s high price-to-rent ratio and extremely limited available housing contribute to its vulnerability. In Tokyo, a prolonged run-up in property values has outpaced income growth, even as demand from domestic and international buyers supports the market.
The report also highlights weak ownership affordability across cities. In many markets, the annual costs of buying and maintaining a roughly 650-square-foot home exceed 40% of a highly skilled worker’s gross income. In several places, renting a comparable property is substantially cheaper.
Why lower bubble risk does not mean affordable housing
UBS describes London’s real home prices as more than 15% below their 2021 level, yet rents remain near highs because of limited supply. Miami’s lower bubble-risk ranking likewise does not mean housing has become inexpensive; high financing and insurance costs continue to weigh on buyers.
The index uses city-level data and cannot substitute for property-specific valuations. It also reflects conditions measured for the September report, not a fresh October price reading. For investors and housing professionals, its central message is the widening gap between markets where prices still outrun incomes and those where expensive financing has already forced an adjustment.
