Spread

The spread is the gap between the highest price buyers will pay for an asset, the bid, and the lowest price sellers will accept, the ask. It is the most direct measure of transaction cost in any market. A dealer selling a one-ounce gold coin at 2,700 dollars while offering to buy it back at 2,600 dollars is charging a spread of roughly 4 percent.

Why it matters

The spread is what market makers earn for standing ready to trade, and it prices the risk they take holding inventory. Tight spreads signal deep, competitive markets; wide spreads signal illiquidity, volatility, or high handling costs. For a buy-and-hold investor the spread is a round-trip toll paid twice, once on entry and once on exit, so an asset with a 4 percent spread must appreciate 4 percent just to break even.

In the gold vs bitcoin debate

Retail physical gold carries some of the widest spreads in mainstream investing, commonly 2 to 8 percent on coins once dealer premiums and buyback discounts are counted, because metal must be shipped, verified, and insured. Bitcoin on major exchanges often trades with spreads below 0.1 percent, though retail platforms layer on fees that widen the effective cost. At institutional size both markets tighten dramatically, but bitcoin's purely digital settlement gives it a structural edge in transaction cost.
