The House That Stopped Listening to Wages

The situation

On the day Spain's government celebrated being the fastest-growing economy in the Eurozone — which it is — a general strike called by the tenants' union and backed by every major labour union hit the country. The trigger was housing. Rents and prices have risen so far, so fast, that 55% of Spaniards now name housing as their chief worry. Wages are rising too. They are not catching up.

The numbers are stark. One in four tenants spends more than 30% of income on rent — three million people who work the first ten days of every month just to pay the landlord. An Oxfam study estimated rent tips 700,000 working people into poverty. Rents rose 43% between 2015 and 2024; wages rose half that, 21%.

How does an economy grow strongly while a majority feel squeezed out of their own neighbourhoods? Two established economic ideas pull in different directions.

The first model: when an asset is priced by its yield

Start with the mainstream one, because it is the simplest: supply and demand. When the quantity of a good people need stays flat while the number of people needing it rises, price rises until some are priced out. No exotic theory required — it is the first page of any economics textbook.

The second idea is older than it looks: the commodification of a necessity — treating something people need to live as a financial asset, priced not by what users can pay but by what an investor will pay for its income stream. Karl Polanyi called land, labour and money "fictitious commodities" in The Great Transformation (1944): things not produced for sale, which markets nonetheless price as if they were, with destabilising results. A home becomes, in effect, a bond that pays rent, and its value is set by what that income is worth to a fund manager in Frankfurt — not by what a nurse in Madrid earns.

The sociologist Javier Gil of Spain's CSIC dates the local break to 2008. After the crash, Spain had a wrecked housing system — mass evictions, banks drowning in bad mortgages — while the world had a glut of cheap capital hunting yield. International funds bought Spanish homes not to live in but to rent out. Gil's claim, which is contested, is that this was decisive: once a large share of buyers chase yield rather than shelter, prices answer to global capital, not local salaries.

Either way, once prices pull free of wages, the trap self-reinforces:

• Rents outpace wages, so renters scramble to buy.
• Extra buying pressure pushes purchase prices up double digits — 11.2% in one recent year, nearly €3,000 per square metre nationally, over €5,000 in Madrid and the Balearics.
• A deposit alone now takes almost two years of full salary, four in the priciest regions. Saving 20% of an average wage, that is a decade or more.
• Priced out of buying, people stay renting, which keeps rents high.

Both doors close at once.

Weighing the two

These explanations are not enemies — they describe the demand side and the supply side of the same market.

The supply case is strong and now the majority view. In 2023 the Bank of Spain estimated a cumulative deficit of 750,000 homes for 2021–2025: in 2025 the country formed about 240,000 new households but built roughly 92,000 homes. Economist Fernando Pinto (Rey Juan Carlos University) notes Spain built around 600,000 homes a year in 2008 on cheap credit; construction then collapsed and never recovered. Only about 2% of the stock is public, far below Western European norms. On that last point, left and right agree: the state abandoned housing policy for a generation.

The commodification case is also evidenced — foreign fund buying is real and concentrated in the hottest markets — but weaker on scale: single-flat private landlords are still about 40% of the market, which caps how much any one actor explains. The industry-aligned reading leans on that figure to reduce everything to supply. The tenant-union reading downplays the shortage to foreground speculation. The honest position holds both: too few homes built, and growing investor demand pricing the ones that exist by yield rather than wages.

Where else this happens

Watch for the signature anywhere: a price that stops tracking what users can pay and starts tracking what an investor will pay for the income. The same housing story runs in Berlin, Lisbon, Dublin, Toronto and Auckland — Berlin's 2021 vote to expropriate corporate landlords and Lisbon's short-let crackdown are reactions to the identical move.

It isn't only housing. Farmland now sells far above what farming it can earn, because investors price the asset, not the harvest. Water rights and carbon credits have followed. Whenever a necessity becomes a globally tradable asset, its price detaches from the local purse that needs it.

What to watch

The two explanations predict different cures, so watch what actually moves prices.

• If it is mainly a supply shortage, building should ease prices — watch whether construction climbs toward the ~240,000-a-year formation rate, and whether prices soften where building accelerates.
• If commodification dominates, new supply helps only at the margin and prices stay above local wages while investor demand persists — watch rent controls and limits on fund ownership, and whether they bite.

An election has now been called over this very issue, after tenant-stabilising decrees were voted down in Congress.

Expectation: ~70% that housing remains the top-cited public concern in Spanish polling through the coming year — because neither cure, building fast enough or re-coupling prices to wages, delivers relief before voters reach the ballot box.
