Special Report
Highlights House prices are rising rapidly across the developed markets, in response to the extraordinary monetary and fiscal policy stimulus implemented to fight the pandemic. Evidence points to the house price surge being driven by monetary policy that has left real interest rates far below equilibrium levels. Supply factors are a secondary cause of the house price boom. Financial stability risks stemming from rising house prices are less acute than the pre-2008 experience, as overall household leverage has grown more slowly during the pandemic and global banks are better capitalized. Rapidly rising house prices are forcing some central banks to turn less accommodative earlier than expected. The recent hawkish turns by the Bank of Canada and Reserve Bank of New Zealand may be canaries in the coal mine for other central banks – perhaps even the Fed – if house prices and household leverage start rising together. Feature The COVID-19 pandemic led to the sharpest economic recession since World War II, alongside an enormous rise in unemployment. Consensus expectations call for the output gap to be closed (or mostly closed) in most advanced economies by the end of this year, but it remains an open question how quickly these economies will be able to return to full employment amid potentially permanent shifts in demand for office space and goods sold at physical, “brick and mortar” retail locations. Despite this sizeable and swift economic shock, house price appreciation accelerated last year in the developed world. Chart 1 highlights that US house prices rose at an 18% annualized pace in the second half of 2020, whereas they accelerated at a high-single digit pace in developed markets ex-US (on a GDP-weighted basis). This, in conjunction with a sharp rise in the household sector credit-to-GDP ratio (Chart 2), has unnerved some investors while raising questions about the implications for monetary policy. Chart 1House Prices Are Surging Around The World Chart 2Rising Fears About Deteriorating Household Balance Sheets Before we discuss the investment implications of the global housing boom, however, we must first accurately determine the reasons why it is happening. The Work-From-Home Effect: Less Than Meets The Eye When analyzing the surprising behavior of the housing market last year, the working-from-home effect brought upon by the pandemic emerges as an obvious factor potentially explaining house price gains. Last year, following recommended or mandatory stay-at-home orders from governments, most office-based businesses rapidly shifted to work-from-home arrangements as an emergency response. However, in the month or two following the beginning of stay-at-home orders, several national US surveys found many office workers preferred the flexibility afforded by work-from-home arrangements. Many employers, correspondingly, found that the productivity of their employees did not suffer while working from home, or that it even improved. Several prominent corporations in the US have subsequently made some work-from-home options permanent, or even allowed employees to work from offices in a different city than they did prior to the pandemic. Newfound work-from-home options have undoubtedly created new demand for housing, and thus explained the surge in house prices seen over the past year in the minds of some investors. However, in our view, evidence from the US, the UK, and France suggests that the work-from-home effect better explains differences in price gains across housing types and within large metropolitan areas, rather than aggregate or national-level changes in house prices. Chart 3 provides some quantification of the impact of work-from-home policies by plotting US resident migration patterns by city. This data has been compiled by CBRE, and the impact of COVID is shown as the change in net move-ins from 2019 to 2020 per 1000 people. This helps control for the underlying migration pattern that existed in US cities prior to the pandemic. Chart 3Work From Home Policies Have Impacted Migration Trends… The chart highlights that the negative migration impact from COVID has been mostly concentrated in New York City and the three most populous cities on the West Coast (by metro area): Los Angeles, San Francisco, and Seattle. And yet, Chart 4 highlights that house price inflation in these four cities has accelerated to a double-digit pace, only modestly below the national average. Chart 4...But Cities With Outward Migration Still Have Very Strong House Price Gains The house price indexes shown in Chart 4 represent aggregate, metro area trends, and clearly some regions within these metro areas have experienced house price deceleration or outright deflation versus gains in areas outside the urban core. But Chart 5 highlights that house prices have declined in Manhattan basically in line with the change in net move-ins as a share of the population, underscoring that double-digit metro area-wide house price gains appear to be vastly disproportionate to changes in net migration. Similarly, Chart 6 highlights that rents decelerated in the US over the past year but remained in positive territory and grew at a 3.5% annualized rate from February to April. Chart 5In Manhattan, House Prices Have Tracked Net Migration Chart 6Rent Costs Have Decelerated, But Have Not Contracted Evidence from Paris and London also suggests that a work-from-home effect is insufficient to explain broad house price gains. Panel 1 of Chart 7 highlights that house prices in France have accelerated significantly, but that apartment prices have decelerated only fractionally in lockstep. Panel 2 shows that the acceleration in house prices does reflect a work-from-home effect, as prices have risen faster in inner Parisian suburbs. Panel 3, however, highlights that Parisian apartment prices, the dominant property type in the urban core, have decelerated modestly. Chart 8 highlights that house price gains have not even decelerated in greater London; they have been merely been modestly outstripped by gains in Outer South East (outside of the Outer Metropolitan Area). Chart 7In France, Parisian Apartment Prices Are Simply Lagging, Not Falling Chart 8In The UK, Greater London Property Prices Are Accelerating The Policy Effect: The Fundamental Driver Of The Housing Market Despite the broader location flexibility that work-from-home policies now provide to potential homeowners, it seems inconceivable that the housing market would have responded in the manner that it has over the past year given the size of the economic shock brought on by the pandemic without significant support from policy. Above-the-line fiscal measures to the pandemic have totaled in the double-digits in advanced economies (Chart 9), and monetary policy has contributed to easier financial conditions via rate cuts, asset purchases, and sizeable programs to support financial market liquidity. Chart 9There Has Been A Massive Fiscal Policy Response To The Crisis In fact, Charts 10-13 present compelling evidence that fiscal and monetary policy have been the core drivers of significant house price gains over the past year. Charts 10 and 11 plot the above-the-line fiscal response of advanced economies against the year-over-year growth rate in house prices as well as its acceleration (the change in the year-over-year growth rate). The charts show a clearly positive relationship, with a stronger link between the pandemic fiscal response and the acceleration in house prices. Chart 10Differences In Last Year’s Fiscal Response… Chart 11…Help Explain Differences In House Price Gains Chart 12Pre-Pandemic Differences In The Monetary Policy Stance… Chart 13…Do An Even Better Job Of Explaining 2020 House Price Gains Charts 12 and 13 highlight the even stronger link between house prices and the pre-pandemic monetary policy stance in advanced economies, defined as the difference between each country’s 2-year government bond yield and its Taylor Rule-implied policy interest rate as of Q4 2019. We construct each country’s Taylor Rule using the original specification, with core consumer price inflation, a 2% inflation target, and real potential GDP growth as the definition of the real equilibrium interest rate. The charts make it clear that easy monetary policy strongly explains house price gains in 2020, particularly the year-over-year percent change rather than its acceleration. This makes sense, given that monetary policy was already quite easy in many countries at the onset of the pandemic – meaning that changes were less pronounced than they would have been had interest rates been higher. The explanation that emerges from Charts 10-13 is that historic fiscal easing, combined with an easy starting point for monetary policy – that became even easier last year – enabled demand from work-from-home policies to manifest during an extremely severe recession. We agree that work-from-home policies have shifted the geographic preferences of some home buyers and likely provided a new source of net demand from renters in urban cores purchasing homes in outlying areas. But we strongly doubt that the net effect of work-from-home policies in the midst of an extreme shock to economic activity would have caused the rise in house prices that we have observed, certainly not to this level, without major support from policy. This underscores that policy, and not the work-from-home effect, has and will likely remain the core driver of the global housing market. The Supply Effect: Mostly A Red Herring Chart 14Countries Fall Into Two Groups In Terms Of The Relative Trend In Real Residential Investment One perennial question that emerges when analyzing the housing market, particularly in markets with outsized house price gains, is the impact of constrained supply. It is frequently argued that constrained supply is squeezing prices higher in many markets, and that the appropriate policy solution to extreme house price gains is to enable widespread housing construction – not to raise interest rates. We do not rule out the potential impact of constrained supply in certain cities or regional housing markets, and we have highlighted in previous research that a positive relationship does exist between population density in urban regions and median house price-to-income ratios.1 But as a broad explanation for supercharged house price gains, the supply argument appears to fall flat. Chart 14 presents the most standardized measure of cross-country housing supply available for several advanced economies, the trend in real residential investment relative to real GDP over time. These series are all rebased to 100 as of 1997, prior to the 2002-2007 US housing market boom. The chart makes it clear that advanced economies generally fall into two groups based on this metric: those that have seen declines in real residential investment relative to GDP, especially after the global financial crisis (panel 1), and those that have experienced either an uptrend in housing construction relative to output or have seen a flat trend (panel 2). If scarce housing supply was the core driver of outsized house price gains, then we would expect to see stronger gains in the countries shown in panel 1 and smaller gains in the countries shown in panel 2. In fact, mostly the opposite is true: Charts 15 and 16 highlight that the relationship between the level of these indexes today relative to their 1997 or 2005 levels is positively related to the magnitude of house price gains last year, suggesting that housing market supply has generally been responding to demand over the past decade. The US and possibly New Zealand stand as possible exceptions to the trend, suggesting that relatively scarce supply may be boosting prices even further in these markets beyond what fiscal and monetary policy would suggest. Chart 15Countries That Have Seen A Stronger Pace Of Residential Investment… Chart 16…Have Experienced Stronger House Price Gains Chart 17Is This Not Enough Supply, Or Too Much Demand? As a final point about the inclination of investors to gravitate towards supply-side arguments related to the housing market, Chart 17 presents a simple thought experiment. The chart shows a simple housing supply-demand curve diagram, in a scenario where the demand curve for housing has shifted out more than the supply curve has (thus raising house prices). Is this a scenario in which supply is too tight? Or is it a case in which demand is too strong? In our view, the tight supply answer is reasonable in circumstances where the increase in demand is normal or otherwise sustainable. But Charts 10-13 clearly showed that housing demand is being boosted by easy policy, which in the case of some countries has occurred for years: interest rates have remained well below levels that macroeconomic theory would traditionally consider to be in equilibrium, and this has occurred alongside significant household sector leveraging (Chart 18). As such, in our view, investors should be more inclined to view the global housing market as generally being driven by demand-side rather than supply-side factors. This Is Not 2007/08 … Yet We highlighted in Chart 2 above that the household sector debt-to-GDP ratio increased sharply last year, which has raised some questions about debt sustainability among investors. For the most part, the rise in this ratio actually reflects denominator effects (namely a sharp contraction in nominal GDP) rather than a huge surge in household debt. Chart 19 shows BIS data for the annual growth in total household debt in developed economies was roughly stable last year, at least until Q3 (the most recent datapoint available from the BIS). Chart 18Low Interest Rtaes Have Fueled Household Leveraging Chart 19Total Credit Growth Has Been Stable, But Mortgage Credit Growth Is Accelerating Chart 20US Mortgage Growth Is Picking Up, As Repayments Slow Consumer Credit Growth But Chart 19 shows the recent trend in total household debt, which masks diverging mortgage and non-mortgage debt trends. In the US, euro area, Canada, and Sweden, household mortgage debt has accelerated to varying degrees, underscoring that households have likely paid down non-mortgage debt with some of the savings that they have accumulated from a significant reduction in spending on services. Chart 20 shows this effect directly in the case of the US; mortgage debt growth accelerated by roughly 1.5 percentage points in the second half of the year, whereas consumer credit growth (made up of student loans, auto loans, credit cards, and other revolving credit) decelerated significantly. This aligns with data showing that US households have used some of their savings windfall to pay down their credit card balances. This changing mix within household debt - less higher-interest-rate consumer credit, more lower-interest-rate collateralized mortgage debt – could, on the margin, help mitigate financial stability risks from the housing boom by moderating overall debt service burdens. The starting point for the latter matters, though, in accurately assessing the risks from rising house prices and increased mortgage debt, particularly in countries where household debt levels are already high. According to data from the BIS, the US already has one of the lowest household debt service ratios (7.6%) among the developed economies (Chart 21).2 This compares favorably to the double-digit debt service ratios in the “higher-risk” countries like Canada (12.6%), Sweden (12.1%) and Norway (16.2%). On top of that, US commercial banks have become far more prudent with mortgage loan underwriting standards since the 2008 financial crisis. The New York Fed’s Household Debt and Credit report shows that an increasing majority of mortgage lending made by US banks since the 2008 crisis has been to those with very high FICO credit scores (Chart 22). This is in sharp contrast to the steady lending to “subprime” borrowers with poor credit scores that preceded the 2008 financial crisis. The median FICO score for new mortgage originations as of Q1 2021 was 788, compared to 707 in Q4 2006 at the peak of the mid-2000s US housing boom. Chart 21Diverging Trends In Global Household Debt Servicing Costs Chart 22US Banks Have Become More Prudent With Mortgage Lending US bank balance sheets are also now less directly exposed to a fall in housing values. Residential loans now represent only 10% of the assets on US bank balance sheets, compared to 20% at the peak of the last housing bubble (Chart 23). This puts the US in the “lower-risk” group of countries in Europe, the UK and Japan where mortgages are less than 20% of bank balance sheets. This compares favorably to the “higher risk” group of countries where residential loans are a far larger share of bank assets (Chart 24), like Canada (32%), New Zealand (49%), Sweden (45%) and Australia (40%). Chart 23Banks Have Limited Direct Exposure To Housing Here Chart 24Banks Are Far More Exposed To Housing Here Like nature, however, the financial ecosystem abhors a vacuum. “Non-bank” mortgage lenders have filled the void from traditional US banks reducing their lending to lower-quality borrowers, and they now represent around two-thirds of all US mortgage origination, a big leap from the 20% origination share in 2007. Non-bank lenders have also taken on growing shares of new mortgage origination in other countries like the UK, Canada and Australia. Chart 25Global Banks Can Withstand A Housing Shock Non-bank lenders do not take deposits and typically fund themselves via shorter-term borrowings, which raises the potential for future instability if credit markets seize up. These lenders also, on average, service mortgages with a higher probability of default, so they are exposed to greater credit losses when house prices decline. However, the risk of a full-blown 2008-style commercial banking crisis, with individual depositors’ funds at risk from a bank failure, are reduced with a greater share of riskier mortgage lending conducted by non-bank entities. This is especially true with global commercial banks far better capitalized today, with double-digit Tier 1 capital ratios (Chart 25), thanks to regulatory changes made after the Global Financial Crisis. Net-net, we conclude that the overall financial stability implications of the current surge in house prices in the developed economies are relatively modest on average. The acceleration in mortgage growth has occurred alongside reductions in non-mortgage growth, at a time when banks are better able to withstand a shock from any sustained future downturn in house prices. However, if house prices continue to accelerate and new homebuyers are forced to take on ever increasing amounts of mortgage debt, financial stability issues could intensify in some countries. Services spending will recover in a vaccinated post-COVID world, as economies reopen and consumer confidence improves, which will likely end the trend of falling non-residential consumer debt offsetting rising mortgage debt in countries like the US and Canada. Overall levels of household debt could begin to rise again relative to incomes, building up future financial stability risks when central banks begin to normalize pandemic-related monetary policies – a process that has already started in some countries because of the housing boom. The Monetary Policy Implications Of Surging House Prices Rapidly appreciating house prices are becoming an area of concern for policymakers in countries like Canada and New Zealand, where the affordability of housing is becoming a political, as well as an economic, issue. In the case of New Zealand, the government has actually altered the remit of the Reserve Bank of New Zealand (RBNZ) to more explicitly factor in the impact of monetary policy on housing costs. The Bank of Canada announced in April that it would taper its pace of government debt purchases and signaled that its decision was based, at least in small part, on signs of speculative behavior in Canada’s housing market. Macroprudential measures like limiting loan-to-value ratios of new mortgage loans are a policy option that governments in those countries have already implemented to try and cool off housing demand. Yet while such measures can help alleviate demand-supply mismatches in certain cities and regions, the efficacy of such measures in sustainably slowing the ascent of house prices on a national scale is unclear. In the April 2021 IMF Global Financial Stability Report, researchers estimated that, for a broad group of countries, the implementation of a new macro-prudential measure designed to cool loan demand reduced national household debt/GDP ratios by a mere one percentage point, on average, over a period encompassing four years.3 If macroprudential measures are that ineffective in sustainably reducing demand for mortgage loans, then the burden of slowing house price appreciation will have to fall on the more blunt instruments of monetary policy. Importantly, surging house price inflation is not likely to give a boost to realized inflation measures – an important issue given the current backdrop of rapidly rising realized inflation rates in many countries. Housing costs do represent a significant portion of consumer price indices in many developed countries, ranging from 19% in New Zealand to 33% in the US (Chart 26), with the euro area being the outlier with housing having a mere 2% weighting in the headline inflation index. Chart 26A Limited Impact On Actual Inflation From Housing Yet those so-called “housing” categories overwhelmingly measure only housing rental costs and not actual house prices. This is an important distinction because rents – which are often imputed measures like in the US and not even actual rental costs - are rising at a far slower pace than actual house prices in most countries, so the housing contribution to realized inflation is relatively modest. So the good news is that booming house prices will not worsen the acceleration of realized global inflation that has concerned investors and policymakers in 2021. Yet that does not mean that central bankers will not be forced to tighten policy to cool off red-hot housing demand that is clearly being fueled by persistently negative real interest rates. In Chart 27 and Chart 28, we show both nominal and real policy interest rates for the “lower risk” and “higher risk” country groupings that we described earlier. The real policy rates are nominal policy rates versus realized headline CPI inflation. The dotted lines in the charts represent the future path of rates discounted by markets. Specifically, the projection for nominal rates is taken from overnight index swap (OIS) forward curves, while the projection for real rates is calculated by subtracting the discounted path of inflation expectations extracted from CPI swap forwards. Chart 27Markets Discounting Negative Real Rates For The Next Decade Chart 28Negative Real Rates Are Unsustainable During A Housing Bubble There are two key takeaways from these charts: Real policy interest rates are at or very close to the most deeply negative levels seen since the 2008 financial crisis. Markets are discounting that real rates will be at or below 0% for most of the next decade. Admittedly, there is room for debate over what the equilibrium level of real interest rates (a.k.a. “r-star”) should be in the coming years. However, we deem it a major stretch to believe that real rates need to be persistently low or negative for the next ten years to support even trend growth across the developed economies. In our view, the current boom in housing demand and mortgage borrowing provides clear evidence that negative real rates are below equilibrium and, thus, are stimulating credit demand. Thus, the only way for a central bank to cool off housing demand will be to raise both nominal and, more importantly, real interest rates. Canada and New Zealand will be the “canaries in the coal mine” among developed market central banks for such a move. According to the latest Bank of Canada Financial Stability Review, nearly 22% of Canadian mortgages are highly levered, with a loan-to-value ratio greater than 450%, a greater share of such mortgages than during the 2016/17 housing boom (Chart 29). Canadian house prices have risen to such an extent that home prices in major cities like Toronto, Vancouver and Montreal are among the most expensive in North America.4 Stunningly, a recent Bloomberg Nanos opinion poll revealed that nearly 50% of Canadians would support Bank of Canada rate hikes to cool off the red-hot housing market (Chart 30). The central bank will be unable to resist the pressure to use monetary policy to slam on the brakes of the housing market – investors should expect more tapering and, eventually, rate hikes from the Bank of Canada over at least the next couple of years. Chart 29Canadians Are Leveraging Up To Buy Expensive Homes Chart 3050% Of Canadians Want A Rate Hike To Cool Housing In New Zealand, worsening housing affordability has reached a point where a 20% down payment on the median national house price is equal to 223% of median disposable income (Chart 31). This is forcing more first-time home buyers to take on levels of mortgage debt that the RBNZ deems highly risky (top panel). Like the Bank of Canada, the RBNZ will prove to be one of the most hawkish central banks in the developed world over the next couple of years as the central bank follows their newly-revised remit to try and cool off housing demand in New Zealand. Who is next? Housing values, measured by the ratio of median national house prices to median national household incomes, are rising in the US and UK but are still below the peaks of the mid-2000s housing bubble (Chart 32). Meanwhile, housing is becoming more expensive across the euro area, but not in a consistent manner, with valuations in Germany and Spain having increased far more than in France or Italy. Housing valuations have actually improved in Australia over the past couple of years on a price-to-income basis. The most likely candidates for a housing-related hawkish turn are in Scandinavia, with housing valuations in Sweden and Norway closing in on Canada/New Zealand levels. Chart 31New Zealand Housing Is Wildly Unaffordable Chart 32Global House Price/Income Ratios Are Trending Higher Investment Conclusions The current acceleration in global house prices is an inevitable outcome of the extraordinary monetary and fiscal easing implemented during the pandemic. Higher realized inflation is pushing real rates deeper into negative territory in many countries, fueling the demand for housing. Central banks in countries with more stretched housing valuations will be forced to turn more hawkish sooner than expected, leading to tapering and, eventually, rate hikes to cool housing demand. This has negative implications for government bond markets in countries where housing is more expensive and real yields remain too low, like Canada, New Zealand and Sweden (Chart 33). Investors should limit exposure to government bonds in those markets over the next 6-12 months. Chart 33Negative Real Yields & Expensive Housing Valuations – An Unsustainable Mix Bond markets in countries where house prices are not rising rapidly enough to force policymakers to turn more hawkish more quickly – like core Europe, Australia and even Japan - are likely to be relative outperformers. The US and UK are “cuspy” bond markets, as housing valuations are becoming more expensive in those two countries but the Fed and Bank of England are not facing the same domestic political pressure to use monetary policy tools to fight the growing unaffordability of housing. That could change, though, if overall household leverage begins to rise alongside house price inflation as the US and UK economies emerge from the pandemic. Current pricing in OIS curves shows that markets expect the RBNZ and Bank of Canada to begin hiking rates in May 2022 and September 2022, respectively (Table 1). This is well ahead of expectations for “liftoff” from other developed markets central banks, including the Fed in April 2023. The cumulative amount of rate hikes following liftoff to the end of 2024 is highest in Canada, New Zealand, the US and Australia. Those are also countries with currencies that are trading at or above the purchasing power parity levels derived from our currency strategists’ valuation models. This highlights the difficult choice that central bankers facing housing bubbles must confront, as the rate hikes that will help cool off housing demand will lead to currency appreciation that could impact other parts of their economies like exports and manufacturing. Table 1Hawkish Central Banks Must Live With Currency Strength Tracking the second-round economic consequences of eventual monetary policy actions to control excessive house price inflation, particularly in “higher risk” countries, is likely to be the subject of future Bank Credit Analyst / Global Fixed Income Strategy reports.
