Spain has the most extreme land collapse in the Western world, says Mike Bird

The land that props up the economy and drowns those who don't own any

Mike Bird, The Economist's Wall Street editor, drops it bluntly in his book The Price of Land: Spain is "the example of the most extreme land bubble and collapse in the entire Western world." He isn't talking about just another crisis. He is talking about an asset that concentrates roughly 35% of the planet's real wealth, that cannot be manufactured or moved, and that serves as bank collateral. With those three properties, property stopped being a good and became the foundation of the financial system. And when the foundation shakes, everything shakes.

Why land doesn't behave like any other market

Bird lists three traits that break every economics textbook. First, the amount of usable land is practically the same as it was two hundred years ago. Second, it cannot be moved: Spain has dirt-cheap land in places where nobody wants to live or work. Third, it lasts for generations, which explains why in London or New York the biggest landowners are families that bought decades ago. Location is everything; a hectare in Cuenca is not worth what a doorway in Madrid is because land is not paid for what it is, but for what it gives access to.

Then the bank comes in. If land rises in value and serves as collateral, more is lent against it. More lending, higher prices. The cycle feeds on itself until someone believes prices will never fall. When they stop rising, the real debt appears: the debt of households and of the institutions that financed the castle. And credit, meanwhile, concentrates on those who already own property; a startup without bricks as collateral has a hard time getting funded.

What happens when an entire country depends on land values

The Japanese case is the warning. Its GDP per capita functionally stagnated because the land crisis broke an entire financial system tied to property. Decades later, it still hasn't fully recovered. Bird's conclusion is uncomfortable: the sensible thing is not to manage the hangover, but to keep the bubble from inflating. China tried the opposite, deliberately bursting its bubble in 2021, and five years later local governments' land sales keep falling and housing prices keep dropping. Hence, in his reading, its massive dependence on exports.

The contrast is Singapore. Lee Kuan Yew considered it unjust that everyone paid taxes to benefit only landowners and bought private land at extraordinarily low prices. Today 90% of households own a semi-public flat, under the one-per-family rule. On paper, it works. The problem is arriving late to that model: in Spain the land is already in private hands.

The hoarding the diagnosis leaves out

The structural analysis falls short for part of the conversation. Some argue that land is abundant —most of Spain is empty— and that what is missing is will: there is unemployment, there are hands and there is technology to build. The explanation given is the diamond market one: hold back to create scarcity. Hoarding certainly exists: developable land held by developers and banks waiting for rezoning, with the complicity of the local council of the day. But not all of the price is speculation. Part of it is pure paperwork: master plans, permits, timelines of years, objections from neighbors, taxes and transfers of development rights.

The other strand of the diagnosis is about wealth, not age groups. Those who already own protect themselves through appreciation; those who don't lose capital while waiting. And not every price rise is a bubble: telling real scarcity from speculation is what separates analysis from alarmism.

The point where this gets stuck is the usual one. Everyone sees the problem. Nobody wants to pay the bill for solving it.
