Securities Immobilization (1973)

mechanism
In 1973 the financial industry quietly ended real stock ownership, and almost no one noticed or voted on it.
Who they are

Securities Immobilization, a 1973 change in how stock ownership works.

What they do

The engine calls it the event that killed direct ownership of stocks.

How it works

Physical stock certificates were locked in the vaults of the DTC and trading shifted to computerized book-entry transfers, with an entity called Cede & Co registered as the nominee owner, so 'owning a stock' became holding a contractual sub-entitlement several layers removed from legal title rather than a certificate in your name.

Why it matters

The engine calls it one of the most consequential financial decisions of the 20th century, made entirely by industry insiders with no democratic input.

The engine's record — word for word
Report #72. The event that killed direct ownership. Physical certificates locked in DTC vaults, trading transitioned to computerized book-entry transfers. Cede & Co registered as nominee owner. The choice was deliberate: rather than building better delivery infrastructure, the industry centralized ALL legal title into a single entity. What 'owning a stock' means changed fundamentally — from holding a physical certificate with your name on it to holding a contractual sub-entitlement several layers removed from legal title. The most consequential financial decision of the 20th century, made by industry participants with zero democratic input.
