What Is a Price Spread?
In a physical bullion market, the price spread is the difference between the published price a market maker is willing to pay, meaning the customer selling price (bid), and the price the market maker is willing to sell, a customer purchasing price (ask). This gap exists in all markets, whether wholesale or retail, and is a normal part of two-way trading.
Spreads can be expressed as:
- Absolute value: the dollar difference between bid and ask.
- Percentage: the spread as a proportion of the asset’s price.
What influences the spread?
- Liquidity: Highly liquid markets, with numerous buyers and sellers, typically have narrower spreads because the greater breadth of market participants allows for more trades to be executed at a given price level. (LBMA).
- Volatility & Risk: Uncertainty often leads market makers to widen spreads to offset the risk of rapid price changes, particularly when covering trade obligations (Investopedia).
- Supply & Demand: Shifts in demand or constraints on supply can create wider spreads, reflecting a bigger gap between prices than efficient market conditions (CME Group).
During March 2020, as global markets reacted to COVID-19 uncertainty, precious metals spreads widened noticeably. In gold, the bid-ask spread increased as both physical delivery constraints and heightened volatility reduced operational opportunities and efficiencies of buyers and sellers (MarketWatch).

What Is Market Depth?
Market depth is the extent of buyer and seller capacity at a particular moment. It is a measure of the volume of marketplace orders at a given price level. With a commodity futures exchange digital platform, it could be seen as reported outstanding buy orders at a price below the last price and sell orders amounting to just above that last price. However, buyers and sellers do not want to show their hand because their volume can spook the market against them, and they hide their true capacity. The true measure of market depth is in the historical dollar volume of transactions.
Of course, present market depth changes constantly as buyer and seller preferences adjust to news, events, price changes and other factors.
How Large Orders Affect Pricing
When a quantity of buy or sell orders is large enough to consume all outstanding orders at the present price, the price level moves to the next available price level. This means the market price level is pushed up by excessive or simply greater buyer volume and down by greater seller volume.
Observing Spreads and Depth Together
Looking at spreads in isolation shows the distance between bid and ask prices at a given moment. A commodity with less depth should provide greater volatility and price movement opportunity. These factors explain why silver is preferred for trading profit opportunities while gold is preferred for portfolio diversification and wealth preservation.
Bringing It Together
Price changes, price spreads and market depth are part of a broader market-reading toolkit. They don’t predict the future or somehow tell you when to transact, but they reveal information that can influence how quickly prices move and how orders are executed.
Monex live pricing shows current bid and ask prices, and market depth can be inferred to an extent through the volume of transactions and open interest in a commodity market, like a gold future on a futures exchange. For a deeper understanding of how these concepts and insights into market strength, direction, depth and relative over/under valuations may apply to precious metals prices, speak with a Monex account representative.
