Bid-Ask Spread

The difference between the highest price a buyer will pay (bid) and the lowest price a seller will accept (ask) — an implicit transaction cost present in every traded market, from stocks to physical precious metals.

Every traded market has a two-sided quote: the bid (what buyers will pay) and the ask (what sellers will accept). The bid is always lower than the ask; the difference is the spread. When you buy at the ask and immediately sell at the bid, the round-trip cost is the full spread — an immediate loss from the moment of entry. Market makers and dealers earn their living from this spread.

In highly liquid markets — large-cap stocks, major currency pairs, gold futures on COMEX — spreads can be fractions of a cent. In less liquid markets — physical silver coins, exotic currency pairs, thinly traded small caps — spreads can run several percent. This matters enormously for short-term traders but is largely irrelevant for long-term investors who hold through many multiples of the spread.

For precious metals investors, the spread deserves particular attention. The spread on electronic gold futures may be minimal, but the spread on physical retail bullion — the difference between what a coin dealer will pay to buy from you versus what they charge to sell to you — can be 3–8% for gold and significantly wider for silver at the retail level. When comparing physical metals to ETFs or futures for investment purposes, the realistic round-trip transaction cost — including bid-ask spread, fabrication premium, and dealer fees — should be part of the return analysis.
