Real Estate Speculation and Housing Bubbles: Aalbers, Harvey, Martin

Real estate speculation is the purchase of land or housing not to use it but to resell it at a higher price, betting that values will keep rising. When that bet becomes widespread and is financed with abundant credit, prices detach from household incomes and a housing bubble forms, which ends in a sharp fall once credit dries up. Three authors explain why housing has become so prone to this cycle: Manuel Aalbers describes its financialization, David Harvey shows how capital uses the city to absorb surpluses and Randy Martin analyses how financial logic settles into everyday life.

Manuel Aalbers and the financialization of housing

Aalbers, a geographer at KU Leuven, defines financialization in The Financialization of Housing (2016) as the growing dominance of financial markets, actors and motives over the economy and social life. Applied to housing, it means that mortgages are securitised and sold to global investors, that funds buy up portfolios of rental flats and that the price of a home depends more on interest rates than on the wages of the neighbourhood. Subprime mortgages packaged in the United States triggered the 2008 crisis, but Aalbers shows the same mechanism at work in Spain, the Netherlands or Brazil with local variations.

David Harvey and the urbanization of capital

Harvey, in The Urbanization of Capital (1985), explains that when industrial production stops being profitable, capital switches to the secondary circuit, that is, to land and buildings. That switch produces construction booms that absorb the surplus for a while, but because buildings are illiquid and long-lasting, overproduction ends in crisis. The Spanish bubble of 1997 to 2007 or the Chinese one of the following decade fit his scheme: cheap credit, mass development, runaway prices and a collapse whose debt is paid by households and taxpayers.

Randy Martin and the financialization of daily life

Martin, in Financialization of Daily Life (2002), watches the phenomenon from inside the home. The mortgage turns every family into an involuntary investor: people are encouraged to see the house as an asset, to refinance in order to consume and to take on risk as if it were freedom. When prices rise that logic seems to work; when they fall, debt exceeds the value of the home and evictions follow. Martin shows that financialization changes not only markets but the way people think about the future, security and the home itself.

Effects of real estate speculation on the city

In the city, real estate speculation translates into prices that push out lower-income residents, gentrification of central neighbourhoods, empty homes held as investments and projects designed for financial return rather than local needs. Beyond the social cost, the cycle creates systemic risk: the 2008 crisis showed that a mortgage market collapse drags down banks, employment and public finances, and the cities most dependent on construction, such as those of the Spanish Mediterranean coast, took a decade to recover.

The responses these authors and later research propose include regulating mortgage credit, limiting institutional purchases of rental housing, taxing empty homes and expanding the public and cooperative stock outside the market. The underlying question is political: as long as housing is treated as a financial asset before a basic need, bubbles will keep recurring and each burst will keep exacting its price in households, neighbourhoods and public budgets.
