Where Does the Price of Silver Come From? The London LBMA Benchmark, Explained

Every time you check spot, run a melt value, or judge a premium, there's a number underneath all of it: the price of an ounce of metal. But where does that number actually come from? Who decides that gold or silver is worth what it's worth on a given morning? For most of the world's metal, the answer traces back to a twice-a-day auction in London, run under a name you've probably seen without knowing what it meant: the LBMA price. Here's what it is, in plain terms, and how it relates to the "spot" your tool grades against.

What the LBMA price actually is

LBMA stands for the London Bullion Market Association, but the price itself is run by an independent administrator called ICE Benchmark Administration (IBA). The LBMA Gold Price and LBMA Silver Price are the global benchmark prices for gold and silver delivered in London, and they're the reference numbers that producers, refiners, banks, funds, and dealers around the world price against. When a dealer quotes you metal "at spot plus premium," that spot reference very likely descends from this benchmark.

It's set on a clear schedule. The gold price is fixed twice a day, at 10:30 and 15:00 London time, and the silver price once a day, at 12:00 noon, both in US dollars per troy ounce. The benchmark is also published in British pounds, euros, Canadian dollars, and a range of other currencies, but those are indicative, for settlement and valuation, not the currency the price is actually formed in. The price is made in dollars.

How the number gets made: a 30-second auction

The part most people don't realize is that the LBMA price isn't a committee's opinion or a survey. It's the result of a live, electronic auction, and the mechanism is elegantly simple.

At the start of each round, the administrator publishes a trial price. The participating firms then have 30 seconds to enter, change, or cancel their orders, how much metal they want to buy or sell at that price. When the 30 seconds are up, the system checks the gap between total buying and total selling. If that imbalance is small enough to be within a set threshold (normally 10,000 ounces for gold, 500,000 for silver), the auction is balanced, and the price is locked in as the benchmark. If the imbalance is too big, meaning far more buyers than sellers or the reverse, the price adjusts up or down and another 30-second round runs. It repeats until supply and demand meet in the middle. The final balancing price becomes the LBMA Gold or Silver Price for that session.

So the number isn't decreed. It's discovered, in real time, by actual buy and sell orders from the market finding the level where they balance. That's why it's trusted: everyone sees the same prices at the same time, the process is auditable, and it's regulated by the UK's financial authority.

A quick history, and why it changed

This process replaced something much older. The London gold price used to be set by the famous "London Gold Fix," a telephone call among a handful of bullion houses that had run, remarkably, since 1919. After scrutiny over transparency, the phone-based fix was retired on March 20, 2015, and the modern electronic auction took its place. Same idea, finding the balancing price, but now transparent, electronic, auditable, and open to far more participants instead of a closed phone line.

One common misconception worth clearing up: only about a dozen firms (major bullion banks) submit orders directly into the auction, which makes it sound like twelve players set the world's metal price. They don't, really. Each of those firms aggregates the buying and selling of a vast pool behind them, miners, refiners, industrial users, funds, and clients large and small. Twelve seats at the table, but the demand flowing through them is genuinely global. So your local dealer's pricing ultimately rides on order flow from institutions you'll never deal with directly.

(A note on the other metals: as of mid-2026, all four precious metals, gold, silver, platinum, and palladium, are administered under the same consistent, governed framework, so the same kind of transparent auction process sits behind each of them.)

Benchmark versus spot: not quite the same thing

Here's the nuance that matters for how you actually use prices, and it's the part most explanations skip. The LBMA price is a benchmark, fixed at specific moments, twice a day for gold, once for silver. The "spot price" you see ticking on a chart is something slightly different: a continuous, live market quote that moves every second of the trading day.

They're tightly related, the LBMA auction is a key anchor that the continuous market forms around, but they aren't identical. The benchmark is a snapshot taken at set times for contracts, settlement, and valuation. Spot is the live running price in between. So when you check spot to value a coin, you're using the continuous quote, and that quote lives in the gravitational field of the LBMA benchmark without being the exact same number at every instant. For pricing a purchase, the live spot is what you want. The benchmark is the official daily reference underneath it.

Why this matters for your buying

You don't need to follow the London auction to buy a coin well. But understanding it demystifies the whole stack of numbers you rely on. When your tool shows a melt value or grades an all-in cost, it's working from licensed live spot data that ultimately descends from this London benchmark. In fact, our spot pages show the LBMA benchmark right alongside the live price, so you can see the official daily reference and the running market quote together, the snapshot and the live number, in one place. That's the foundation the whole "spot plus premium" world is built on, and it's reassuring that the base layer is a transparent, regulated, auditable auction rather than someone's guess. The mystery isn't in where the metal price comes from. It's in the premiums and fees layered on top, which is the part worth actually checking. (Here's the glossary if any of the price terms are fuzzy.)

One thing worth stating plainly: the spot price our tool values against comes from an independent licensed market-data feed, not from any dealer or shop. That stays true even when you see "where to buy" links to dealers next to a lot. Those links are a convenience for buying, and they never influence the spot price, the melt value, or the grade. The number underneath is independent of anyone we link to, by design.

Drop a price into Quick Check and the spot it values against traces all the way back to that twice-daily London auction. You're not trusting a number from nowhere. You're trusting one with a very well-lit paper trail.

The short version

The price of gold and silver comes, at its foundation, from the LBMA benchmark: a transparent electronic auction run in London by an independent administrator, gold twice a day, silver once, in US dollars per ounce, where actual buy and sell orders balance to set the number. It replaced a century-old telephone fix in 2015, it's regulated and auditable, and the "spot" you price against is the live market quote that forms around it. No hype, no mystery, just where the number actually comes from.
