Monetary commodities like silver and gold have high stock-to-flow ratios. Silver’s ratio is over 20 or 30, and gold’s ratio is over 50 or 60. Specifically, the World Gold Council estimates that 200,000 tons of gold exists above ground, and annual new supply is roughly 3,000 tons, which puts the stock-to-flow ratio somewhere in the mid-60’s as a back-of-the-envelope calculation.
