Between the vault and the buyer sits an industry of armoured vehicles, sealed cargo, bonded warehouses and insurance clauses. It rarely makes news, and it is the reason a spot price in London can diverge from a bar in New York.
For three decades official institutions were net sellers of bullion, and the policy consensus treated the metal as a museum piece. Then, quietly, the world's reserve managers reversed. The reasons are less about inflation than about the plumbing of settlement.
There is no single gold price. There is a London settlement number, a New York futures curve, a Shanghai premium and a jeweller's counter in Dubai — and the distance between them is where the market lives.
For half a century it was rational to store your gold in someone else's basement. Then the calculus of counterparty risk changed, and reserve managers started chartering aircraft.
