How the price of housing became the defining economic issue of the 21st century

The UK completed 425,000 new homes in 1968 — England accounted for the large majority. At the peak of the postwar building programme — rationed materials, simpler technology, a country still clearing rubble — the UK built more than twice what England builds today. In 2023-24, England completed approximately 199,000 new build homes, serving a population around ten million larger.

The gap is not a measurement problem or a data artefact. What changed?

The supply case — and the question it can’t answer

The standard answer is planning constraints, and the standard answer is correct, as far as it goes. In England, the ratio of house prices to median earnings stood at around four times in the mid-1990s. By 2022 it had peaked at around 8.5 times and remained above 8 times in 2023, per ONS affordability data. Australia’s OECD price-to-income index reached approximately 153 in Q2 2024 (indexed to 2015=100), meaning house prices relative to incomes were more than half again as high as in 2015. Canada suffered the worst deterioration in the OECD from 2004 to 2024, with price-to-income ratios worsening by roughly 80% over that period.

Christian Hilber and Wouter Vermeulen, writing in the 2016 Economic Journal, estimated that house prices in England would have risen approximately 100% less between 1974 and 2008 had planning constraints not become progressively more restrictive. Restrict supply in a growing city and prices rise. The economics is not complicated.

And the supply case genuinely explains something. The gap between 425,000 completions in 1968 and 199,000 in 2023-24 is partly a gap between planning systems — between a postwar regime that presumed development was a public good and a subsequent one that treated it as a burden requiring justification. Green belts expanded. Local opposition acquired legal teeth. The discretionary nature of the English planning system, where every application requires individual assessment rather than simply meeting a code, made refusal cheap and delay routine. The Hilber-Vermeulen finding is not marginal: had regulatory constraints held at their 1970s level, something close to half of England’s price growth over the following four decades may not have happened.

But the supply diagnosis, taken alone, leaves a question that it cannot answer. If the problem is planning constraints — regulatory rules that restrict where and how densely housing can be built — then the solution is obvious: build more permissively. That solution has been obvious for roughly forty years. Multiple governments, across multiple parties, in multiple countries, have identified the problem, commissioned reviews, issued white papers, set targets, and produced approximately the same output. So why has no government fixed it?

The question sounds like a critique of incompetence. It isn’t. The rest of this article is about why fixing the problem is not in the interests of the people making the decisions.

Who blocks supply, and why that’s entirely rational

England’s planning system — built on the Town and Country Planning Act 1947 and its successors — concentrates veto power over new development in local planning committees. Those committees are made up of elected councillors. Councillors represent constituents. And in the areas where housing is most needed and most fiercely opposed, the constituents who show up to planning meetings, who write letters, who vote in local elections, are homeowners.

The research on this is direct. Fang, Stewart and Tyndall, writing in the Journal of Urban Economics in 2023 (doi:10.1016/j.jue.2023.103608), studied housing votes across Toronto from 2009 to 2020. They found that councillors who represent wards with higher homeowner shares are significantly more likely to vote against large housing developments, particularly when those developments fall within their own ward. A ten percentage point increase in local homeownership correlated with 47 fewer units permitted per square kilometre. Their conclusion was blunt: homeownership is among the strongest predictors of a councillor voting against development.

Why? Because the arithmetic is not subtle. Take a household holding a £400,000 home with a £200,000 outstanding mortgage. That household has £200,000 in equity. A ten percent fall in house prices does not cost them 10% of anything abstract — it destroys £40,000 of real wealth they may be counting on for retirement, school fees, or passing something to their children. The incentive to prevent that happening is specific, personal, and rational.

The Right to Buy compounds the problem structurally. The Housing Act 1980 sold approximately 1.5 million council homes by 1990. This would have shifted tenure without consequence had it been paired with replacement. It wasn’t — and the restrictions on replacement were deliberate, not incidental.

The council housing stock fell from approximately 5.5 million units in 1979 to around 4.4 million today. Many of those homes are now rented back from private landlords at market rents higher than the original council rents — the same assets, the same tenants, higher costs, public subsidy gone private. Calling this a policy failure misreads the outcome. As a mechanism for converting publicly subsidised social infrastructure into private wealth-producing assets, it worked exactly as designed.

Right to Buy: the mechanism in detail

The Housing Act 1980 was structured to prevent replacement. Local authorities were required to use 75% of Right to Buy receipts to service existing debt; the remainder was subject to further restrictions on capital spending. This meant that each sale reduced the net stock permanently — not temporarily, but by design. The legislation did not fail to anticipate the depletion of social housing stock. It ensured it. The council housing stock fell from approximately 5.5 million units in 1979 to around 4.4 million today. Many of those homes are now rented back from private landlords at market rents higher than the original council rents. The irony is structural, not incidental: the policy transferred publicly subsidised assets to private ownership, prohibited replacement, and created a new landlord class collecting higher rents from the same tenants the original stock was built to house.

The Germany deviation

Germany’s housing politics in the 1970s, 1980s, and 1990s produced a different set of structural choices. The homeownership rate settled around 46-50%, the lowest in the EU, held in place by a combination of high real-estate transfer taxes (3.5-6.5% depending on the state), no mortgage interest deductibility, and strong tenant protections including the Mietpreisbremse — the rent brake, which restricts rent increases to 10% above local comparative rents — and Kauf bricht nicht Miete, the principle that a property sale does not terminate an existing tenancy.

These structures had a measurable effect. Through the 1990s and 2000s, German price-to-income ratios remained near their historical norms. While the UK and Australia were diverging sharply, Germany was not. This is not coincidence. If you make housing expensive to transact, impossible to deduct against income, and relatively unrewarding to hold as a speculative asset, fewer people treat it as a speculative asset.

Then the European Central Bank pushed rates toward zero — and eventually below zero — and Germany’s structural buffers began to give way. Berlin real house prices rose approximately 160% from 2000 to their 2022 peak, with the steepest gains after 2010. Munich apartment prices near-tripled in the decade to 2021-22, reaching approximately €9,000-9,500 per square metre. Germany’s social housing stock, which had around 1.8 million units in 1989, now stands at roughly 1.08 million — more than 700,000 units lost as price-control periods on older stock expired without renewal. German authorities currently estimate a shortage of around 700,000 housing units.

Germany did not fail in the same way as Britain or Australia. Its structural choices bought two decades of relative stability while Anglophone markets broke almost immediately following financial deregulation. When the monetary environment became extreme enough, those protections gave way too. Structure matters enormously. It is not sufficient.

Germany's housing crisis in numbers

Berlin real house prices rose approximately 160% from 2000 to their 2022 peak, with the steepest gains after 2010 when ECB rates approached zero and went negative. Munich apartment prices near-tripled in the decade to 2021-22, reaching approximately €9,000-9,500 per square metre. Germany's social housing stock fell from approximately 1.8 million units in 1989 to roughly 1.08 million today — more than 700,000 units lost as price-control periods on older stock expired without renewal. German authorities estimate a current shortage of around 700,000 housing units. The lesson is not that Germany failed in the same way as Britain or Australia. The lesson is that its structural protections held for two decades under conditions that broke the Anglophone housing markets immediately — and that when the monetary environment became sufficiently extreme, those protections eventually gave way too.

How housing became money

Germany’s structural protections worked because they prevented housing from becoming an investment class. The UK, Australia, and Canada chose differently — not in a single dramatic decision, but through a sequence of financial deregulations whose cumulative effect was to convert housing from a consumption good into a leverageable asset.

In the UK, the process ran roughly as follows. The Bank of England removed the “corset” restricting bank lending growth in 1980. The Building Societies Act 1986 allowed building societies to borrow wholesale and compete with banks, ending their mutual constraint on credit expansion. Building societies’ share of new mortgage lending fell from 96% in 1977 to 66% by 1987, per Bank of England Quarterly Bulletin data. The New Economics Foundation’s analysis of the financialisation of UK homes traces how this deregulatory sequence shifted the binding constraint from income multiples — how much you earn — to asset value — how much the house is worth. That shift created a feedback loop: rising prices justify larger loans; larger loans drive prices higher.

Here is why that matters for the supply question. In a goods market, high prices signal suppliers to produce more. Supply rises to meet demand; prices moderate. That is the market mechanism supply advocates are invoking when they argue for deregulation. But housing in its financialised form does not behave like a goods market. In an asset market, high prices signal holders to retain and buyers to enter before prices rise further. Supply is not the primary constraint — sentiment is. And the people who control supply decisions are the same people holding housing as their primary asset.

Australia formalised this with negative gearing: property investors can offset losses from investment properties against other taxable income, an explicit state subsidy for holding investment properties at a loss in the expectation of capital gain. In the lead-up to Australia’s May 2026 federal budget, the Albanese government was widely reported to be preparing restrictions on negative gearing for new acquisitions, with Treasury modelling a cap of two investment properties — though no specific reform had been confirmed at time of writing.

The political-ideological consequence of financialisation is not just distributional. It is perceptual. In a consumption market, high prices for renters are a failure signal — something is going wrong and needs fixing. In an asset market, they are the measure of success. Rising rents confirm rising yields, which confirm rising valuations, which confirm that the people who own property made a good decision. The reframe is not a market outcome. It is the downstream effect of converting the dominant electoral constituency into asset holders and then asking them to vote on policy.

What ultra-low rates did

Everything described so far — the supply constraints, the NIMBY arithmetic, the financialisation of lending — was in place before 2008. What the decade after 2008 added was an extreme demand-side accelerant.

The basic mechanism is straightforward. Falling interest rates raise the present value of future income streams; assets with long duration get repriced most dramatically. Housing is especially exposed because households can leverage four to five times income against it — a leverage ratio no other asset class offers ordinary people at this scale. BIS Working Paper No. 665, studying house prices across 47 economies, found that short-term interest rates are a strong and surprisingly important driver of house prices — changes in rates up to five years prior continue to affect prices today, with effects gradual rather than immediate. ECB Working Paper No. 2789 found that at ultra-low real interest rates, the sensitivity of house prices to rate changes is substantially higher than conventional estimates predict. Run that in reverse: rates approaching zero meant asset values were repriced sharply upward, with the amplification greatest precisely because rates had been so low for so long.

The Bank of England launched quantitative easing in March 2009. By its peak, the programme totalled over £895 billion in asset purchases. The portfolio rebalancing effect — central bank buys gilts, forcing capital elsewhere in search of yield — directed large flows toward residential property, which combined tax advantages and leverage in ways bonds couldn’t match. The Bank’s own Quarterly Bulletin analysis describes this portfolio rebalancing as a feature of QE transmission. The distributional consequences were arithmetically obvious before the policy was implemented.

Theresa May, in her July 2016 campaign speech launching her bid for the Conservative leadership, put it plainly: “Monetary policy — in the form of super-low interest rates and quantitative easing — has helped those on the property ladder at the expense of those who can’t afford to own their own home.” It was an unusually frank statement from a senior politician. It changed nothing.

The 2010s housing crisis was not a new problem. It was the existing system — supply-constrained, ownership-concentrated, politically captured — meeting an extreme demand-side shock. The shock amplified what was already there.

QE as regressive redistribution

When a central bank buys government bonds at scale, it compresses yields and forces capital toward assets with higher returns. That capital has to go somewhere — and residential property, with its leverage potential and tax advantages, absorbs a large share of it. The mechanism is not conspiratorial. It is arithmetic. Asset price inflation transfers wealth from those who hold assets to those who... already hold assets. Those who rent rather than own get nothing from the appreciation. They do, however, help service the debt of the landlords who buy the houses that QE helped inflate. The Bank of England's own analysis describes this portfolio rebalancing effect as a feature of QE transmission. The distributional consequences were visible before the policy was designed.

The inheritance machine

The logical endpoint of this system is now visible. Housing outcomes are increasingly determined not by income, education, or professional trajectory but by birth circumstances — specifically, whether your parents own property and when they bought it.

UK research published in the Journal of Economic Inequality in 2023 (doi:10.1007/s10888-023-09563-z) tracked intergenerational homeownership patterns and found that ownership rates among adults whose parents did not own have declined disproportionately — the gap between people from owning and non-owning households has widened as average prices have risen. The Australian pattern runs in the same direction: cohorts who entered the market before the crisis accumulated housing wealth that younger buyers, entering at price-to-income ratios two to three times higher, cannot replicate at equivalent life stages.

The “Bank of Mum and Dad” — parental contributions to house deposits estimated by Legal & General and Cebr in 2017 to make it equivalent in scale to the UK’s ninth-largest mortgage lender — is not a charming cultural quirk. It is the mechanism through which a property-owning class reproduces itself. The children of homeowners receive equity contributions that allow them to meet deposit requirements; the children of renters do not. Those who cannot access parental capital either rent indefinitely, leave expensive cities, or delay ownership by a decade or more. Each additional year of delayed ownership is a year of wealth accumulation lost.

The arithmetic compounds viciously. A person who buys at 27 with parental help starts accumulating equity during the steepest earning years of their career. A person who buys at 38 — if they ever buy — has spent their thirties paying rent that covered someone else’s mortgage while saving a deposit against a target that moved upward. By the time the second person owns, the first has a decade of asset appreciation behind them and is probably thinking about what to pass to their own children. The gap between them is not a gap in earnings or effort. It is a gap in when their parents happened to buy.

An inheritance economy is what this system built — not incidentally, but as the downstream consequence of rational decisions made by people who benefited from them.

What would fix it, and why it won’t happen

The economics of what would fix this is largely settled. As-of-right upzoning near transit hubs — mandatory permissions to build at higher density without case-by-case planning approval. A land value tax on location value, not improvements, which would be economically non-distortionary because land supply is fixed and cannot be reduced in response to taxation. Removal of investment tax advantages — Australia’s negative gearing, the UK’s capital gains exemption on primary residences — that subsidise speculative holding. The Mirrlees Review of 2011, the most comprehensive review of UK taxation in a generation (IFS/Oxford University Press), recommended comprehensive land value taxation and was ignored.

The problem is not knowledge. It is political economy.

Every one of these interventions directly reduces the asset value of the dominant electoral constituency. Homeowners vote at higher rates than renters. They concentrate in marginal constituencies. They have a precise financial stake in planning permissions and tax policy. A politician who successfully delivers affordable housing — by genuinely allowing supply to meet demand — has cut the wealth of the people most likely to vote and most likely to notice. That is not irrational democratic behaviour. It is completely rational democratic behaviour, from the perspective of the politician.

Land value taxation: the economics

Henry George's argument in Progress and Poverty (1879) was that taxing land value — not buildings or improvements, just the location itself — would be economically non-distortionary because land supply is fixed. You can't build less land in response to being taxed. The modern economic consensus agrees: an LVT falls on the economic rent generated by location, penalises land-banking and speculative holding, and removes the perverse incentive to leave productive land underdeveloped. Economists across the political spectrum, from Milton Friedman to Joseph Stiglitz, have endorsed the principle. The Mirrlees Review of UK taxation in 2011 recommended it. It has never been implemented at scale in a major democracy. The reason is not economic. It is that LVT requires existing landowners to pay for the social value of their locations, which they currently capture for free. Those landowners vote.

There is also a structural feature of housing politics that makes the coalition for reform self-defeating. Renters, aspiring buyers, priced-out young professionals — the natural constituency for housing reform — are not a stable political bloc. They eventually buy, or give up, or leave the expensive city. When they buy, they join the defensive coalition. The defensive coalition never converts; the reform coalition continuously haemorrhages members to homeownership. Every person who crosses from renter to owner joins the side defending high prices against the side that was recently harming them.

New Zealand provides the partial exception. The National Policy Statement on Urban Development (2020) combined with the Resource Management (Enabling Housing Supply and Other Matters) Amendment Act 2021 mandated upzoning across five major urban centres — not permissive upzoning, but mandatory. Research published in 2023 and 2024 found measurable effects: approximately 24% increase in long-run equilibrium floorspace in Auckland, per Greenaway-McGrevy (Regional Science and Urban Economics, 2025), and rents measurably lower relative to a synthetic counterfactual — Greenaway-McGrevy and So (University of Auckland Economic Policy Centre, 2024) estimate three-bedroom rents 22-35% below where they would otherwise have been by 2022. The reform required bipartisan support from both Labour and National — a rare political configuration. Its durability remains uncertain.

What the exception proves is not optimism. It proves that the lock can be broken. It requires a political configuration that is rare, temporary, and must be institutionalised quickly before the newly-forming homeowner constituency reasserts itself. That is not a critique of the New Zealand reform. It is a description of the political physics.

What was built

Return to the opening numbers. The UK completed 425,000 homes in 1968. England completed approximately 199,000 new builds in 2023-24, serving a population ten million larger. The answer to “what changed?” has been built across this article.

Housing became an asset class held by the voters who control planning decisions. Financial deregulation created a feedback loop between house prices and credit expansion. The postwar social housing stock was sold and not replaced. Ultra-low rates and quantitative easing inflated asset values across a decade and distributed the gains to those who already owned. The political economy that produced all of this is structured so that those who can fix it benefit from not fixing it.

But the most consequential dimension is temporal. This system is not just producing unaffordable housing today. It is building an inheritance economy for the decades ahead. The decisive variable in a person’s housing outcome will increasingly be not what they earn, not where they went to university, not what they contribute to a productive economy — but whether they were born into the right property-owning family at the right point in the price cycle.

That is the society being built. Not accidentally. As a consequence of choices, stacked over forty years, that were rational for the people making them. Whether those choices are reversible is a real question. Whether the people with the power to reverse them have any incentive to do so is a different question. The answers are not compatible.
