Spot Price vs. LBMA Benchmark: Which Should Your Store's Prices Follow?

If you price gold, silver or platinum items from the market, the first decision is which market price to use. Two references come up most often: the live spot price you see on dealer websites and trading screens, and the LBMA benchmark prices set by auction in London. They're related but not the same, and choosing between them affects how often your prices change and how easy they are to explain.

What the spot price is

The spot price is the current price for immediate delivery of a metal, quoted continuously while markets are open. It's what most people mean when they say "gold is at $X today," and it moves minute to minute. For a fuller explanation, see our post on what a gold spot price is.

Because it updates constantly, spot is the most current view of the market. That's a strength for buyers and sellers who want to trade at today's value, and a challenge for anyone printing prices on paper.

What the LBMA benchmark prices are

The London Bullion Market Association publishes benchmark prices for the four main precious metals. According to the LBMA, they are set by auctions run by ICE Benchmark Administration, an independent administrator, at fixed times each London business day:

Gold and silver are quoted in U.S. dollars per troy ounce. Platinum and palladium are quoted in dollars per fine ounce of 99.95% purity. The LBMA notes that real-time benchmark data comes from licensed market data providers or IBA, and public figures are published with a delay.

These benchmarks are widely used to settle contracts and value holdings. For a retailer, the key feature is that they change only once or twice a day.

Comparing them for retail pricing

Live spot price

• Pros: Always current, matches what customers see when they check prices on their phones, and protects your margin when the market moves fast.
• Cons: Prices can change while a customer is browsing, which some shoppers find unsettling. You also need a system that can keep tags updated.

LBMA benchmark price

• Pros: Changes only at set times, so prices are stable for hours. Easy to explain: "We price from the London afternoon gold price."
• Cons: Can lag the market. If gold moves sharply after the London afternoon auction, your prices won't reflect it until the next day. Licensing and access to real-time benchmark data can also be a consideration.

A middle path: some stores use a live spot feed but only refresh tags at set intervals, such as every hour or at fixed times during the day. That keeps prices reasonably current without constant movement.

Which is right for your store?

There's no single correct answer, but a few patterns hold:

• Bullion and coin dealers usually follow live spot closely, because customers compare prices online and margins on bullion are thin.
• Jewelry stores often care less about minute-by-minute moves, since craftsmanship and design are a larger share of the price. A once- or twice-daily update is often enough.
• Pawn shops fall in between. Gold jewelry sold near melt value behaves more like bullion; designer pieces behave more like retail jewelry.

Whatever you choose, be consistent

Two rules apply no matter which reference you use:

1. The shelf price should match the register. Many state inspectors follow NIST Handbook 130, under which a store passes a price verification at 98% accuracy or better. If your tags follow one reference and your point of sale follows another, you're inviting mismatches.
2. Don't use market moves to fake a sale. The FTC's Guides Against Deceptive Pricing (16 CFR Part 233) say a "was" price must be a real price you offered for a reasonably substantial period. A price that drifted up for an hour with the market isn't a fair basis for a "reduced" sign.

Pick a reference, write it down, and tell your staff what it is. When a customer asks why a price changed, "the gold market moved and our prices follow it" is an answer most people accept.
