EXECUTIVE SUMMARY

  • Tightening financing conditions, slowing growth and soaring inflation are putting pressure on the European housing market. Swiftly rising mortgage rates have dramatically reduced home affordability at a time when home prices have already reached unsustainable levels in many European countries. With higher energy prices and inflation further eroding disposable income, credit demand for home purchases is bound to subside over the next quarters.
  • Germany’s housing market is most at risk among the major European economies. Property prices increased by more than 50% in real terms since 2015 while home affordability has dropped by -30%. We project a price correction of -8% in real terms until end-2024, followed by around -5% in France and the UK. Price corrections in Spain and Italy, whose housing markets did not really take off after the 2000s’ bubble burst, will be less severe at around -3%.
  • However, the slump in house prices will not materially mitigate the growing social challenge of rapidly declining home affordability, especially for the younger generation. The massive expansion of money supply since the mid-2010s due to quantitative easing inflated prices of non-productive investment in areas that are highly collateralized, such as real estate. Thus, home affordability for younger generations and vulnerable households will become an increasingly pressing public policy issue.
  • At the same time, soaring energy prices, higher construction costs and rising interest rates could also challenge the European “renovation wave”. Unlike after the 2008 financial crisis, to address this, policy interventions need to be geared towards social and green aspects. We find that a combination of increasing the supply of housing and scaling up public support for vulnerable households could strengthen households’ incentives to invest in energy-efficiency measures, advancing one of the key goals of the EU Green Deal.


European households hit by higher mortgage interest-rate burden as the economy continues to slow.

Tightening financing conditions, slowing growth and soaring inflation are putting pressure on the European housing market. Although 2022 has been the year of price corrections across many markets, the implications of housing make it one of the most sensitive and unique sectors. For many, housing is the main form of investment, but even when not owned, real-estate-related payments (be it for rent or mortgage loans) take up a large part of monthly incomes, and housing is a basic social need.

While the overvaluation of real estate is a global concern, Europe is particularly affected by the current energy crisis and its impact on real incomes (which were declining even before Russia’s invasion of Ukraine). As Europe slides into recession, rising interest rates  and higher energy costs have put purchasing a home out of reach for most households, adding to pre-crisis price pressures resulting from disrupted supply chains for construction materials. And the effects on house prices vary across the Eurozone.  

In this paper, we analyze the current developments in residential real estate in the largest European countries based on four factors: demand, supply, prices and financial conditions. We then project the scale of the potential price correction and assess the impact on home affordability, with a focus on the implications for the young generation and the green transition.

Our fundamental analysis suggests a significant slowdown is looming in the near term (Table 1). Demand is showing clear signs of weakness as wage growth is not keeping up with inflation, which has eaten into the savings boosted during the Covid-related lockdowns. Supply is also receding, with construction orders and construction companies’ business confidence deteriorating further in November (see Figure 1; insufficient demand was named the top limiting factor in the latest ESI  release, overtaking labor and material shortages). Looking ahead, the picture does not improve: demand for housing is set to slow further, with European households already overburdened by the increasing cost of living. Typically, the first signs of a real estate downturn come from weak demand and supply, which translates into decline in sales and a fall in prices. The size of the fall depends mostly on the willingness to sell, which itself depends on the link between growth and unemployment, and the safety nets in place.

While there is not a certain threshold for overvaluation, a perceived rate of appreciation that exceeds the 95th percentile generally indicates a housing bubble.

Price developments, the crux of the matter. The largest European economies did not enjoy the same pandemic housing boom as the US or other developed markets. In nominal terms, real estate prices increased, but at more modest rates; in real terms, they have declined already.  To measure the degree of overvaluation in real estate market – which makes it more prone to a severe correction once the wind shifts – we use the distribution of past perceived appreciation rates.  We find that the housing market in Germany and the UK, and to a lesser extent in France, are most overvalued among the largest economies in Europe (Figure 2). In these countries, affordability has also declined dramatically over the years, and more so than in other countries if measured on the basis of the price-to-rent/price-to-income ratios (Figures 3 and 4).

The overvaluation was supported by asset-price inflation fueled by quantitative easing (QE). Successive rounds of quantitative easing carried out by the main central banks since 2008 supported high asset prices in two ways: directly, because excess liquidity did not translate into productive investment but was rather used to consolidate balance sheets and create buffers (hoarding), and indirectly, because the timely interventions were seen by markets as a stop-loss, incentivizing risk-taking behavior. While this is most evident in the stock market, house prices in many countries have also benefited from this money (see Figures 5 and 6). With the failure of QE failure to meet its theoretical goal, i.e. to bring inflation to target and take the Eurozone economy out of the ICU,  the price of residential real estate has grown faster than disposable income in every large European economy, with the exception of Italy (see Figure 5).

While overvaluation is a necessary condition, it is not enough: a macro-financial shock is required to spark a price correction. Possible triggers could be either tightening credit conditions or a slowing growth outlook, and the combination of both will certainly increase the probability of a price correction.

Looking ahead, we expect the largest correction of real house prices in Germany due to pre-existing conditions  and an impending contraction of economic activity, followed by France and the UK. Based on the recent trends in prices and panel-data estimation of changes in real house prices,  we expect a correction over 2023-2024 in all the five largest Eurozone economies, although it will be particularly deep in Germany, France and the UK (see Table 2).

Pre-existing conditions matter the most in Spain and Italy, setting the stage for a smaller correction, but those forecasts are the ones with the greatest downside risks due to the combination of a sluggish recovery expected for 2024 (around +0.8-0.9%), a persistently high output gap and long-lasting risks of high public debt. In addition to these purely macro-financially-driven forecasts, we also model the relationship between the performance of real estate-related equities and the performance of official real price indices. We find that Germany and France are the most exposed to a correction, followed by the UK. In Italy, residential real estate prices still have room to catch up, which is unlikely under the current macroeconomic conditions.

Rising vulnerabilities: households’ leverage, credit conditions and lending rates

Bank lending to households for home purchases is slowing after solid growth rates since 2020. In most European countries, low interest rates spurred housing credit. Recently, however, credit demand has subsided in response to tightening financing conditions (Figure 7), weakening housing market prospects and deteriorating consumer confidence. The latest data on monetary aggregates for October also confirm that banks have become more cautious in providing mortgage loans, with monthly flows almost halved (from EUR15bn to EUR8bn). Annual growth of housing lending eased to 4.2% (from 4.4% in September). Moreover, banks expect to significantly tighten their credit standards in Q4 as demand is likely to slow further.

Higher interest rates are also affecting households’ credit behavior. Demand for variable-interest-rate mortgages seems to be picking up again across the Eurozone, albeit with significant country differences, as households want to avoid “locking in” the currently high fixed interest rate (Figure 8). A further rise in rates could squeeze borrowers’ debt-servicing capacity, already challenged by spiking energy costs and inflation, and further lower borrowing capacity.

The transmission from policy rates and bank lending rates has intensified in recent months across the bloc’s largest economies. The average pass-through ranges between four months in Italy and Spain to up to six months in Germany and France. Recently, lending rates have become more sensitive to changes in policy rates, especially in Germany and Italy (Figure 9). Since we expect the peak in key interest rates in Q1 2023, households will become more exposed to interest-rate risk in the next quarters. In particular, Italy and Spain would be impacted earlier due to their higher share of variable-rate loans (with declining debt-to-income ratios providing some buffer). Conversely, outstanding mortgages in Germany and France are largely at fixed rates (but household leverage in these countries is edging up) (Figure 10). Overall, households have become more vulnerable to house price dynamics in 2023-24.

Social implications: no home without a mortgage

Slowing growth coupled with the rising cost of living and the shortage of affordable housing is likely to increase the number of vulnerable households. Around 8% of the EU’s population is currently living in a household where total housing costs represent more than 40% of the total disposable household income. Additionally, household disposable income has been growing at a slower pace than house prices (Figure 11). In the largest four countries, the correction in housing prices could help improve the financial standing of prospective buyers, but higher non-discretionary spending due to inflation offsets the benefit of lower prices in nominal terms. Using our macroeconomic expectations and the housing-price correction estimations, we estimate the housing-cost overburden rates. In Spain, we expect the housing-cost overburden rate to increase from 8.2% to 9.6% in 2024. In Italy, we could see this ratio rise from the lowest rate of 7.2% at the height of the pandemic to 9.0% in 2024, while in France, the ratio could reach 6.3% (up from 4.8%). Germany has the highest housing-cost overburden rates in our sample (15.5%), and we expect this to stay relatively stable at 15.8%.

Figure 11. Housing-cost overburden rate, in % *

Sources: Eurostat, Allianz Research. * Note: The housing cost overburden rate is the percentage of the population living in households where the total housing costs ('net' of housing allowances) represent more than 40 % of disposable income ('net' of housing allowances).

While the housing-cost overburden encompasses all costs related to housing, if we look at home purchasing, it is not only diminished purchasing power that makes prospective buyers think twice. Even if there is a correction in house prices, rate movements suggest that servicing mortgage debt might also become unaffordable. In the US, the median 30-year mortgage rate has more than doubled in the last 12 months and is at its highest level in the last two decades. Homeowners that did not lock in a low interest rate for mortgages may also be forced to sell in an environment of depressed demand.

Challenges are different as much between countries as within countries. Germany has the lowest owner-occupied rates for housing of the four Eurozone sample countries (49.5%). In contrast, Spain (75.8%) and Italy (73.7%) have a higher share of homeowners. In France, first-home buyers tend to be younger than in neighboring countries. Nonetheless, all countries have one thing in common: affordability gaps are pervasive especially in urban areas, within lower income deciles, especially for renters and amongst the youth. Homeownership among younger households has been decreasing in several advanced economies, not just in Europe, driven by increasing labor income inequality and uncertainty. Faced with high house prices and low, risky incomes, younger households might choose to not engage in an illiquid risky investment, which in turn results in lower wealth accumulation.

Price increases, higher mortgage interest rates and the diminished purchasing power have put pressure on the most vulnerable households. Homeownership is relatively high amongst the lowest income quintile in Spain (73% of households, according to Eurostat), much higher than in Italy (48%) or France (33%).  Deteriorating credit conditions might create more tensions in Spain and Italy than in France and Germany, where homeownership is not the norm. Although the housing-cost overburden rate is higher for younger people in Germany (23.9% for those aged 15 to 29) when compared to the entire population (19.9%), as well as in France (youth: 7.1%, all ages: 5.9%). In Spain, it is relatively similar at 8.3% for the youth and 8.2% for the entire population. In Italy, there is no difference in homeownership between younger and older cohorts (8.7%). It is important to highlight that in Spain and Italy, younger people tend to leave their parents’ homes at a later age, which might also provide an opportunity to accumulate initial assets (Figure 13).

The risks in the European housing market also put “green renovation” in jeopardy

Soaring energy prices, higher construction costs and rising interest rates could also challenge the European “renovation wave” under the EU’s Green Deal ambitions. Enhancing the energy efficiency of buildings through renovation and retrofitting represents a key plank in the EU climate policy agenda and will be essential for the EU to achieve its net-zero emission target by 2050.
We find that energy-efficiency renovations have become more attractive as additional energy savings over the long run outweigh higher renovation and installation costs (due to the rising costs of construction materials and labor, Figure 14).  We find that the amortization time has declined from 13.2 years to less than 10 years for an average dwelling if structural price pressures in the building and construction sector as well as labor costs remain contained and energy prices stabilize at higher levels.

Policy implications: more effort needed to reduce shortage in affordable and energy efficient housing

How can policymakers respond to improve home affordability? There are several options: (i) releasing more land for development, (ii) streamlining approval processes for permits and re-zoning, (iii) assessing incentives to build rental properties, (iv) encouraging more innovation in construction (including greater use of building technology and energy-efficiency measures), (iv) increasing supply, including of social housing and (v) providing access to financing for energy-efficiency improvements and renovation for vulnerable households (which benefit most from energy savings but find upfront investment costs too high), including “green mortgages”.  This also includes introducing a percentage-based affordable housing requirement on new developments that benefit from public sector support via credit guarantees and/or grants.

Policies that improve borrowing conditions for younger cohorts will prove to the most effective to increase their chances of acquiring real estate. Younger households are relatively more sensitive to policies that improve credit conditions. Figure 13 illustrates the negative correlation between home ownership age spread (i.e. the difference in homeownership rates between the younger cohort and the rest of the population in percentage points) and the proportion of young households with mortgage debt.

Scaling up improvements in energy efficiency will also depend on policy support for vulnerable households (see section above). While the affordability of energy-efficiency measures has increased over the lifetime of the investment, declining real disposable income has increased the budget constraints of households, which cannot afford the front-loaded expenditure. Thus, it is essential to scale up public sector support in the form of grants or interest-rate subsidies (via more favorable credit terms, such as the ones offered by national development banks and some banks in the form of “green mortgages, see Box 1).

However, policies should resist stimulating demand further, given the existing supply-demand imbalances and avoid resorting to short-term solutions, such as relaxing prudential regulations to enable households to borrow more. The program to subsidize buying a home needs to be carefully designed and remain limited in size to minimize risks to the financial sector.
