Across more than 80 countries nominal house prices climbed in 2025, producing an unmistakable global boom that stretches from Mumbai to Melbourne. The headline figures are hard to ignore: double‑digit annual gains in a group of 21 countries, sharp rallies in major cities and a flood of cross‑border buyers seeking hard assets. Yet beneath the veneer of rising asking prices lie two uncomfortable truths — a currency‑adjusted reality that softens much of the apparent appreciation, and a striking geographic concentration that leaves whole regions vulnerable to corrections.
Sydney and Melbourne have become emblematic of the phenomenon. Mandarin is now a common background sound in central Sydney, Chinese buyers remain prominent among overseas purchasers, and Australian housing rose by roughly 9.6% in 2025 after 18 consecutive months of gains. That surge is mirrored elsewhere: Mumbai investment properties jumped about 35% year‑on‑year, Vietnam’s new‑build apartment prices leapt 20–30% with Hanoi and Ho Chi Minh City up as much as 40% and 23% respectively, and luxury markets from Dubai to Singapore recorded outsized foreign demand.
Western markets have not been immune. The United States posted strong gains — Zillow reported a 6.8% year‑on‑year median rise in the first half of 2025 and Case‑Shiller data showed a renewed upswing into early 2026 — even as 30‑year mortgage rates lingered above 6%. The European Union recorded a 5.5% annual rise in prices in the third quarter of 2025 and rents were up roughly 3.3%, with countries such as Portugal and Croatia seeing decade‑long doublings and Hungary recording exceptionally large cumulative increases.
Two powerful demand forces underpin the upturn: population flows and cross‑border capital. Migration and settlement have mechanically increased housing demand in many advanced economies, while wealthy international buyers — notably from mainland China — have returned to or expanded activity in markets such as Singapore, Hong Kong, Australia and Dubai. These buyers value liquidity, yield and political diversification; in Singapore and Dubai in particular, permissive purchase rules, low taxes and attractive financing terms make real estate an accessible dollar‑linked asset.
Governments have reacted unevenly. Some have tightened access or added levies to cool foreign demand — Canada enacted temporary foreign purchase bans and Singapore doubled a stamp duty for non‑nationals in 2023 — while others have paused or rolled back measures to support local markets. Australia and several other countries implemented time‑bound restrictions on foreign purchases, but policy reversals and the elasticity of wealthy investors mean these measures are a blunt instrument at best.
Despite the visible gains, two ‘inflation illusions’ temper the narrative. When prices are converted into dollars or adjusted for inflation, the picture is far less rosy. A cross‑country analysis of 50 economies showed nominal cumulative gains of over 30% in local currency, but a roughly 2% fall in dollar‑denominated ‘real’ prices; the Bank for International Settlements’ dataset covering 63 central banks found global real prices down about 0.7% in 2025 Q3. Some countries — South Korea among them — have already seen real prices decline for multiple consecutive quarters even as local headlines cheer nominal increases.
The second illusion is geographic concentration. Most of the upside is carried by prime urban cores and luxury segments, while suburban condos and smaller cities often lag or fall. Canada’s story is illustrative: premium homes in Toronto and Vancouver posted strong gains while other segments tumbled, producing a bifurcated national picture. The same pattern appears in Japan and Korea, where Tokyo and Seoul have outperformed regional markets, and in other economies where inner‑city scarcity — not broad‑based demand — supports headline numbers.
The implications are significant. High nominal prices strain affordability, push household debt ratios higher and increase the political salience of housing as an election issue — as seen in the United States where policymakers debate curbing institutional purchases of single‑family homes. Financial stability risks are also uneven: heavy mortgage exposure in Australia and concentrated asset price risk in major city cores could translate into sharper corrections if funding conditions or capital flows reverse. At the same time, global cities that successfully attract people and investment will probably retain their price resilience, further entrenching spatial inequality.
If the past few years are a preview, the housing landscape ahead will be one of winners and losers. The winners are the truly global cities with supply constraints and a continued influx of people and capital; the losers are mid‑sized and peripheral places that lack those advantages. For policymakers, the challenge is balancing measures to cool speculative inflows and protect affordability without choking the supply adjustments and investment that support economic dynamism.
