The paradox of the biggest number
Jewellery is typically the largest single category of gold demand, often around 40–50% of annual offtake. It is also nearly useless for predicting price. Why? Because it is slow, price-elastic, and geographically dispersed. It responds to price rather than setting it.
Price is set at the margin — by the flow that is willing to transact in size, right now, at whatever the screen says. That is financial demand: ETFs, futures, and official reserves. Those flows can be a small fraction of annual tonnage and still dominate price, because they arrive concentrated in time.
Elasticity is the mechanism
Here is the core intuition. Mine supply is highly inelastic in the short run — you cannot open a mine because the price went up this month. Demand is more elastic. When an inelastic supply curve meets a shifting demand curve, small demand shifts produce large price moves.
Think of it as a seesaw with a fixed left side. If supply barely responds to price, then any change in demand has to be absorbed almost entirely by price.
Why this matters for your trading
- Stop reading "record jewellery demand" as bullish. It is often a response to price, or a function of Indian wedding dates, and it frequently peaks near price tops as buyers rush in.
- Watch the marginal buyer. A quarter where ETF flows turn positive by a few hundred tonnes can overwhelm a jewellery slowdown several times larger, because it is concentrated and price-insensitive.
- Supply shocks fade. Because supply is inelastic, a disruption causes a spike but not a sustained repricing — unless it changes the multi-year supply outlook, which individual events almost never do.
How to check this yourself
Get the annual supply-and-demand balance from the World Gold Council and find the smallest category in it. Now ask: if that category grew 10%, how much price impact would you expect? The value of the exercise is discovering that the biggest category is rarely the one that moves price — the marginal, price-insensitive buyer does that.
