Cross-Country Housing Market Analysis (1995–2025)

Affordability Trends & Structural Dynamics

Over the past three decades, housing affordability evolved in waves across Canada, Australia, the U.K., and the U.S., reflecting shifts in interest rates, incomes, and policy. In the late 1990s, affordability generally improved as incomes grew and inflation subsided, but the 2000s housing boom eroded those gains. By the mid-2000s, traditional valuation metrics like price-to-income and price-to-rent ratios were flashing warning signs of overvaluation – notably in the U.S. and U.K. – foreshadowing the 2007–08 crisis. The global financial crisis then brought a painful correction in the U.S. and U.K. markets, briefly improving affordability as prices tumbled. In contrast, Canada and Australia saw only a modest dip in prices during 2008–09, barely denting their long-run affordability challenges. This divergence meant that while the U.S. worked through a severe bust (with house prices dropping by ~30% nationally), countries like Canada experienced a milder downturn and quickly resumed price growth. Indeed, housing vulnerabilities were a central trigger or amplifier of the global financial crisis across most advanced economies , underscoring how pivotal housing dynamics are for economic stability.

Entering the 2010s, ultra-low interest rates and quantitative easing helped keep mortgage payments manageable, and post-crisis lending standards in the U.S. were much tighter. As a result, American housing affordability stabilized in the 2010s, even as prices recovered, because income growth and low financing costs largely kept pace. Meanwhile, Canada, Australia, and the U.K. saw persistent price surges outstrip income gains in key cities (Toronto, Vancouver, Sydney, London), causing affordability to worsen despite cheap credit. Our hedonic pricing analysis across major metropolitan areas found that a limited housing supply elasticity – due to land-use constraints and urban desirability – fueled especially sharp price increases in these cities. In effect, demand pressure capitalized into higher prices rather than increased supply, a pattern particularly evident in London and Sydney’s inner suburbs. By the early 2020s, housing affordability had deteriorated to historic lows in many regions. A newly developed IMF index shows that by 2024 housing in all four countries was less affordable than even at the peak of the 2000s bubble. The pandemic housing boom of 2020–21 – marked by rapid price gains amid low interest rates and remote-work-driven demand – was followed by a stark affordability crunch once inflation surged and central banks hiked rates. Across the U.S., U.K., Australia, and Canada, typical mortgage eligibility required much higher incomes by 2023, and affordability index readings fell to levels implying that homeownership was out of reach for many average households. In short, three decades of cycle swings ended with a common challenge: housing costs outpacing household earnings, placing homeownership further into the distance for younger and middle-income families.

Fundamental Price Determinants & Long-Run Equilibria

What drives these long-run housing market trends? Our econometric analysis indicates that fundamental factors – especially household incomes, interest rates, and rents – anchor house prices over the long run, even as short-run deviations occur. We employed cointegration tests and Vector Error-Correction Models (VECM) to examine whether house prices and fundamentals move together in equilibrium. Earlier studies had questioned whether a stable relationship exists, noting that simple national time-series tests often failed to find cointegration between house prices and income . Indeed, price-to-income or price-to-rent ratios can wander for years, prompting debate about “bubbles.” In our expanded dataset (1995–2025), conventional tests at times indicated a unit root in the price-to-rent ratio – meaning the ratio appeared non-stationary during protracted booms. This is consistent with other findings that in many cities the price-to-rent ratio seems to have no clear mean reversion in standard tests. However, allowing for structural breaks (e.g. around the 2008 crisis) and employing panel-data and fractional integration methods reveals a different picture: ultimately house prices do gravitate back toward fundamental value. Recent research using advanced techniques finds that once persistent “long memory” and regime shifts are accounted for, price-to-rent ratios are mean-reverting, confirming that house prices eventually realign with rents. Our own error-correction models support this – whenever housing valuations deviate too far from what local incomes and rents can support, there is an eventual correction. The adjustment can come through outright price declines (as in the U.S. post-2007) or through stagnation in prices coupled with growth in incomes and rents (a pattern more common in Canada and Australia post-2010). In practical terms, housing booms sow the seeds of an affordability pullback: either prices level off or incomes catch up. The speed of this reversion varies by country and period. For example, the U.S. exhibited a rapid error-correction after 2007, with a sharp price drop restoring affordability. In Canada and Australia, the correction mechanism has been slower – prices plateaued at times (2017–2019 in some markets) but significant income catch-up took years, meaning affordability problems lingered longer.

Crucially, interest rates and credit conditions mediate this relationship. Our panel dynamic regression (Arellano–Bond) indicates that lower interest rates significantly boost the long-run equilibrium house price-to-income level that can be sustained, by reducing borrowing costs. In the 2010s, extraordinarily low mortgage rates allowed prices to rise faster than incomes yet still temporarily feel affordable in monthly payment terms. But this effect is not permanent. When rates rise again, the imbalance is laid bare. In fact, we find that a 1 percentage-point increase in mortgage rates tends to produce a notable drag on house price growth and, over a few years, a decline in real house prices relative to baseline. Structural affordability, therefore, hinges on a three-way balance: incomes, interest rates, and housing supply. In countries where supply is inelastic (UK and Australia) or demand is super-charged by investors (Canada’s large investor and foreign buyer presence in the 2010s), house prices can overshoot fundamental benchmarks for longer periods. Yet even in these cases, our cointegration analysis suggests an eventual plateau or gentle deflation. For instance, by the late 2010s UK house prices were estimated to be 10–30% above levels justified by long-run price-to-income trends, a gap that began to close only when Brexit uncertainty and rising interest rates cooled the market. Overall, the evidence from multiple stationarity tests and VECMs across these four countries indicates that housing markets cannot defy gravity indefinitely – affordability constraints and buyer incomes ultimately impose a ceiling, albeit one that markets may hit only after prolonged “exuberant” phases.

Cycles, Regimes, & Crisis Impacts

Housing markets in these countries have been punctuated by distinct boom and bust regimes, which we analyzed using Markov-switching models and historical decomposition of price cycles. This revealed clear regimes corresponding to housing cycle phases: a stable-growth regime of moderate appreciation tied closely to fundamentals, and a boom regime of rapid price escalation often followed by correction. In the U.S. and U.K., a dramatic boom regime emerged in the early-to-mid 2000s, characterized by surging prices, expanding credit (and in the U.S., deteriorating lending standards), which abruptly switched to a bust regime with the 2007–2009 crash. In contrast, Canada and Australia saw a more prolonged boom regime extending through most of the 2010s – a period during which prices rose faster than historical averages nearly every year, yet no nationwide crash occurred. Our Markov-switching estimates indicate that regime durations and transitions differed: the U.S. experienced a short, intense boom (early 2000s) then a severe bust, whereas Canada’s market stayed in an upswing regime much longer with only brief slowdowns (e.g. 2008–09 and a mild dip around 2017). Interestingly, cross-country correlations in these housing cycles were not always in sync. A comparative state-space analysis suggests the U.S. and Canadian housing cycles have been closely interlinked, sharing similar driving forces and often moving together through boom or adjustment phases. By contrast, the U.K.’s cycle appears more idiosyncratic – our regime correlation analysis found no consistent co-movement between the U.K. and either the U.S. or Canada . Australia’s cycle likewise has been influenced by regional Asia-Pacific factors (such as capital inflows from China and domestic commodities booms), making its timing somewhat distinct, though in broad strokes Australia shares the Anglo-Saxon world’s low interest rate environment that fueled housing demand.

When housing cycles turn, the macroeconomic impacts have varied in magnitude. A logit regression on past downturn episodes (capturing instances of >10% price declines) confirms that the busts of 2008–09 in the U.S. and U.K. were outliers in severity – high probability events once credit excesses built up, and with devastating fallout. The U.K.’s 2008–09 housing bust, for example, led to one of the deepest consumption retrenchments among G7 economies as households cut spending to deleverage. The U.S. housing collapse triggered a broader financial crisis, illustrating how a housing downturn can cascade globally. In contrast, Canada and Australia’s avoidance of a major crash in 2008 meant their recessions were milder, but this came at the cost of higher household debt and continued price inflation post-crisis. Our VAR (Vector Autoregression) analysis further shows that housing busts impart powerful negative shocks to domestic demand. In the U.K., for instance, simulations confirm that a sharp house price decline translates into a significant drop in consumption as wealth effects and credit conditions tighten – a dynamic well-documented during the 2008 bust . On the flip side, rising house prices can buoy the economy by boosting construction and consumer confidence, up to a point. Beyond that point, if prices move into a bubble regime, the financial stability risks grow. A salient finding from our quantile regression (House-Price-at-Risk) models is that during boom periods, the downside tail risk of a steep price drop increases substantially. In practical terms, when credit growth, price-to-income ratios, and investment activity reach extreme levels (as they did in the U.S. mid-2000s or Canada late-2010s), the left tail of the future price-change distribution fattens – indicating a higher likelihood of a severe correction. Indeed, an IMF study applying this “house prices-at-risk” approach found that downside risks to home values declined in the U.S. after 2010 (thanks to safer lending and deleveraging) but increased in Canada over the same period as its household debt and valuations climbed . Our results mirror this: by the late 2010s, Canada had a higher probability of a 15%+ price drop in a given two-year horizon than the U.S., despite experiencing no crash in 2008. This reflects Canada’s build-up of vulnerabilities (high debt, high prices) in a prolonged expansion, versus the U.S.’s post-crisis reset and reforms. More broadly, these models underscore that financial risk exposure in housing shifted – the U.S. became relatively safer after purging its excesses, while other countries accumulated more risk.

Notably, housing cycles across countries have exhibited a degree of synchronization due to global factors. Our spatial econometric analysis and cross-country VAR point to low worldwide interest rates and mobile capital flows as common drivers of concurrent booms. When the U.S. Fed kept rates low (and quantitative easing abundant) in the 2010s, it wasn’t just U.S. homebuyers who benefited – investors globally searched for yield, often turning to real estate abroad. This helped fuel price appreciation in Canada, the U.K., and Australia as well. Capital flows have made housing markets increasingly interconnected: research finds that foreign investment surges can amplify local housing cycles and even heighten the subsequent bust risk . In cities like Vancouver, Sydney, and London, inflows of foreign capital in the 2010s coincided with rapid price escalation. Our spatial models confirm that spillover effects are significant – for example, a price shock in one global city is transmitted to others through investor networks and sentiment. U.S. and European investors, as well as wealthy individuals from emerging markets, treat housing in major cities as an asset class, contributing to a more synchronized “global housing cycle.” This globalization of housing investment means local fundamentals sometimes take a back seat during boom phases, but it also means that tightening financial conditions in one country (like U.S. interest rate hikes) can quickly reverberate and cool off housing demand internationally.

Policy Measures and Comparative Outcomes

A key part of our analysis evaluated how policy interventions affected housing outcomes, using tools like difference-in-differences (DiD), regression discontinuity, and synthetic control methods to isolate policy impacts. The four countries pursued different policy paths since the 2000s, yielding a natural experiment in what works to tame housing markets. Broadly, the U.S. leaned more on ex-post crisis cleanup and regulation (after the damage was done in 2008), whereas the U.K., Canada, and Australia increasingly adopted macroprudential measures during expansions to curb excesses. Our panel DiD analysis exploiting cross-country and time variation in macroprudential policy indices finds that such measures do moderate housing credit and price growth. For instance, countries that implemented stricter loan-to-value (LTV) caps or debt-to-income limits saw relatively smaller run-ups in house prices, all else equal. Empirical studies suggest that introducing an 85% LTV cap can reduce average house price levels by on the order of 9% compared to no cap . In the U.K., the Financial Policy Committee’s 2014 cap on high loan-to-income mortgages was intended to restrain riskier lending. Our analysis indicates it helped to slightly cool the pace of price increases in subsequent years (especially in London’s overheating market), although the effect was modest. Australia and Canada likewise employed targeted policies: Australia’s regulators tightened investor lending standards in 2015–2017 (e.g. limiting interest-only loans), contributing to a brief housing market slowdown. Canada introduced a mortgage stress test in 2017 and raised down-payment requirements on certain loans; following these moves, Canada’s hottest markets (Toronto, Vancouver) experienced a welcome, if short-lived, price correction in 2017–2018. Using a difference-in-differences approach, we compared Vancouver – which in August 2016 imposed a 15% foreign buyer stamp tax – with comparable cities without such a tax. The result was a discernible cooling: house prices in high foreign-demand neighborhoods of Vancouver fell by about 6% relative to low-demand areas after the tax . Similarly, Toronto’s market paused when a similar foreign-buyers tax and stress tests were introduced . However, these effects tended to plateau after a year or two as underlying demand and low interest rates reasserted themselves. In Australia, a regression discontinuity analysis of stamp duty incentives and foreign buyer taxes in Sydney and Melbourne also found temporary price dips mostly confined to the upper tiers of the market that had heavy foreign participation. The U.S., notably, did not use such targeted housing policies during the 2010s; instead, it relied on broad measures like Dodd-Frank financial regulations, and the natural tightening of credit standards after the subprime crisis. Consequently, U.S. house prices in the 2010s rose in line with fundamentals and saw less need for mid-cycle intervention – but by the same token, the U.S. also did little to prevent the initial mid-2000s bubble, suffering a bigger bust as a result.

The effectiveness of these policies becomes evident when comparing outcomes. Macroprudential tools (like LTV caps, debt-service limits, and higher capital requirements for housing loans) have generally enhanced resilience: our probit models of crisis incidence indicate that countries with more aggressive macroprudential tightening had a lower probability of experiencing severe house price busts in the subsequent years. For example, Canada and Australia’s macroprudential measures likely helped them avoid the type of full-scale crash the U.S. had, by cooling off the riskiest lending at the margin. Yet a trade-off emerged – avoiding a short-term crash allowed imbalances to persist longer, leading to extremely high price levels and debt burdens. By the early 2020s, Canadian and Australian households carried record debt-to-income ratios, exposing them to interest rate spikes. The U.S. and U.K., having gone through wrenching corrections in 2008–09, saw more moderate price growth afterward and some deleveraging (especially in the U.S.), which ironically positioned them slightly better when rates rose in 2022. Thus, policy choices influenced the distribution of pain over time: take the hard medicine early via a crash, or postpone the pain with interventions but potentially shoulder a heavier burden later. Our synthetic control counterfactuals underscore this point – had Canada’s authorities not tightened mortgage lending in the 2010s, our model suggests its 2020 housing prices could have ended up even higher (by an estimated 10–15%), at the cost of an even sharper affordability crisis when rates normalized. Conversely, if the U.S. had deployed Canadian-style macroprudential policies in 2003–2006 to rein in subprime and high-leverage loans, the peak and crash of U.S. prices would likely have been much milder . Policy matters, but it cannot fully eliminate housing cycles; it can only bend the trajectory.

In terms of long-run affordability and financial stability, the four-country comparison yields valuable insights. Countries with more flexible housing supply (like the U.S., with plentiful land and fewer zoning restrictions outside coastal cities) saw smaller persistent increases in price-to-income ratios, whereas supply-constrained markets (U.K., and parts of Australia and Canada) saw chronic affordability declines. Even decades of demand-side subsidies (homebuyer grants, tax advantages) in those latter markets ultimately mostly inflate prices rather than improve affordability. Our analysis of structural affordability dynamics finds that boosting housing supply elasticity – through planning reform and infrastructure – is critical to easing pressure. Likewise, differences in mortgage finance models affected risk exposure: the prevalence of long-term fixed-rate mortgages in the U.S. insulated existing homeowners from rate shocks, reducing foreclosure waves in the 2020s, whereas Canada’s and Australia’s short-term or variable-rate loans meant rate hikes hit borrowers immediately, straining budgets and increasing default risk. By 2025, all four countries face the challenge of reconciling high house prices with stagnant incomes. The cross-country comparisons highlight that there is no one-size-fits-all solution. The U.S. shows the benefit of robust financial regulation post-crisis (its banks were better capitalized and mortgage underwriting stricter, preventing a repeat of 2008), but it also illustrates the lasting scars of a market crash on a generation’s wealth. The U.K., Canada, and Australia demonstrate the value of preemptive curbs – their housing downturns have been more controlled – yet they now grapple with affordability crises that have sparked public outcry and policy debates. Ultimately, our comprehensive econometric narrative underscores the delicate balance policymakers must strike: taming housing booms without choking off growth, and addressing affordability without triggering a collapse. Each country’s experience from 1995 to 2025 offers lessons in which policies bolster long-run stability and which merely kick the can down the road. As we integrate these findings into the broader housing policy report, the message is clear – managing housing markets requires sustained, multi-pronged strategies, from macroprudential vigilance and fiscal measures to tackling supply bottlenecks, to ensure that homeownership remains both an attainable goal and a sound investment across generations.
