Why gold has endured as money for 5,000 years

From the earliest coins of Lydia to the reserves held in central bank vaults today, gold has served as money and a store of value for roughly five millennia. That longevity is not an accident. It follows from a rare combination of physical and economic properties.

Scarcity

All the gold ever mined would fit into a cube of roughly 22 meters on each side. New mine supply adds only about 1.5–2% to the above-ground stock each year, so no authority can expand the supply quickly.

Durability

Gold does not rust, tarnish or corrode. Coins recovered from ancient shipwrecks look much as they did when struck. A store of value must survive time, and gold does.

Divisibility and uniformity

Gold can be divided into grams or combined into 400-ounce bars without losing value, and one ounce of pure gold is identical to any other. That makes it easy to price and trade.

No counterparty

Unlike a bond or a bank deposit, physical gold is not someone else's promise to pay. That is why it is held in reserves and why savers turn to it in periods of uncertainty.

What this means for savers

Gold is not a growth asset like a business, and it pays no interest. Its role is preserving purchasing power across generations, which is why a measured long-term allocation is how many families use it.
