A market maker stands ready to buy and sell at posted prices without knowing which side a customer will take. Surviving that obligation depends entirely on what happens in the seconds after a trade.
The business is spread capture, not direction
A market maker aims to buy slightly below and sell slightly above a fair mid-price, earning the difference across a large number of transactions.
Holding an outright view on where gold goes next is a different business. A dealer who takes directional positions has stopped making markets and started speculating.
Keeping those activities separate is why trading desks impose position limits that are enforced independently of the traders themselves.
Hedging converts a position into a spread
When a dealer buys metal from a customer, it typically sells an offsetting futures contract almost immediately. The physical metal and the short futures position move in opposite directions.
What remains is the difference between the price paid and the reference price, which is the spread the dealer intended to earn.
The hedge does not remove all risk. Basis risk persists, since physical prices and futures prices do not move in perfect lockstep.
Inventory has to be financed and stored
Metal sitting on a dealer's books ties up capital and incurs vault charges. Those costs run daily whether or not the inventory turns.
Dealers therefore manage turnover as carefully as margin. Slow-moving product is priced to move, and fast-moving product can be quoted more tightly.
This is visible at retail, where common bullion coins carry narrow spreads and unusual items carry wide ones.
Quote width responds to uncertainty
As volatility rises, the price can move meaningfully between the customer's decision and the dealer's hedge. That execution risk is priced into a wider quote.
Thin markets have the same effect. If the hedge itself would be difficult to place quickly, the dealer widens rather than refusing to quote.
Watching spreads widen across a market is therefore a reasonable read on how difficult dealers currently find it to lay off risk.
Retail flow is a source of information
A dealer seeing sustained one-way customer flow learns something about demand before it appears anywhere public. Persistent buying drains inventory and forces replenishment at wholesale.
That feedback shows up as widening retail premiums, since the dealer must pay up to restock and passes the cost forward.
Premiums on small coins consequently behave as a rough gauge of American retail sentiment, moving somewhat independently of the wholesale price itself.
