The gold market is built on far more paper claims than actual metal, and that's a hidden risk for anyone who thinks they own gold.

• For every bar of real gold in a vault, there are about nine paper claims saying someone owns it.
• The whole system only works as long as people don't all ask for their real gold at once.
• Banks push people toward "paper" gold by making real, physical gold expensive and inconvenient to hold.
• The paper version is free to hold and comes with tax perks, so most people never take real delivery.
• The same setup applies to other assets backed by physical stuff — it falls apart if too many people demand the real thing.

Outlook: As long as confidence holds the system runs fine, but a rush to claim physical gold could expose how little actually exists.
