Land

The oldest asset. Finite, immovable, and the collateral behind most banking systems.

The invention

The problem. Settled agriculture made a specific piece of ground worth defending and worth recording.

Land registers are among the oldest documents in every civilisation that had writing. Egyptian surveyors re-established boundaries after each Nile flood, which is where practical geometry comes from. Property records exist because the alternative to a register is a fight.

Where it has failed

Not a list of disasters. A pattern library.

  1. 1636Dutch Republic

    Speculation follows the boom

    Land and property speculation accompanied the tulip episode, financed by the same credit expansion.

    Asset bubbles are usually credit events wearing an asset's clothes.

  2. 1926Florida

    The land boom

    Lots sold sight unseen at escalating prices; a hurricane and a rail embargo ended it before 1929 arrived.

    Illiquid assets bought with leverage on the expectation of a greater buyer. This template has never gone out of use.

  3. 1991Japan

    The land price collapse

    Japanese land values fell for over a decade, taking the banking system with them.

    When land is bank collateral, a property correction is automatically a credit crisis.

Where it stands today

You now have the shape. Here is the reading.

Live from public data, pulled at request time. Read it with the failures above in mind — not because a repeat is due, but because knowing the mechanism is what lets you recognise one early.
