Not an Exchange — a Handshake Market
The LBMA has no trading floor and no central order book. It's an association of bullion banks, refiners and vaults that trade directly with each other over the counter, holding hundreds of billions of dollars of gold between London's vaults. Its real job is setting standards and running the twice-daily benchmark auction, not matching individual trades.
From a Room at Rothschild's to an Algorithm
The London Gold Fixing began in 1919 with five bullion dealers meeting at N M Rothschild & Sons, literally standing a small flag upright on the desk to pause trading and settle on a price, then lowering it if more time was needed. That ritual was replaced in 2015 by an electronic, ICE-run auction after regulatory scrutiny of the old process — but the 10:30am and 3:00pm London rhythm has barely changed in over a century.
The List That Guards the World's Gold Bars
LBMA's "Good Delivery List" is the global registry of accredited refiners whose gold and silver bars are trusted and accepted without re-assay by vaults everywhere. A bar from a Good Delivery refiner can move between London, Zurich and Singapore without ever being melted down and re-tested — a large part of why London has stayed the world's physical bullion hub.
The Vaults Under the City
London's bullion vaults — the Bank of England's among them — collectively hold one of the largest gold stockpiles on Earth, mostly as a byproduct of LBMA's role as the settlement location for so much OTC trading. Most of that metal never leaves the vault; ownership simply changes on a ledger.
Contracts & Products Traded
LBMA trading isn't standardized futures — it's bilateral, over-the-counter dealing in physical bars and account positions between member banks, refiners and vaults. Gold moves in 400-ounce Good Delivery bars, silver in 1,000-ounce bars, alongside unallocated and allocated storage accounts, forwards, and gold loans and leases arranged directly between members. The one genuinely standardized product is the twice-daily benchmark itself: the LBMA Gold Price (AM and PM) and the LBMA Silver Price, each set by an ICE-run electronic auction rather than a matched order book. There's no lot size or expiry date to speak of — the product is trusted physical metal and a reference number, not a contract.
Role in Global Price Discovery
The LBMA Gold Price and Silver Price are the reference numbers the rest of the gold world builds on — gold-backed ETFs value their holdings against it, central banks mark reserves to it, and mining companies recognise revenue off it. Jewellers and refiners from Mumbai to Beijing effectively price off London even when they trade locally. Sitting geographically and in trading hours between Asia's morning session and COMEX's US afternoon, London is the literal midpoint of each day's 24-hour metals relay — the price handed off from SGE and SHFE each morning becomes the base that COMEX and, eventually, the next day's Asian session react to.
During the old physical Fixing, a small flag standing upright on the desk meant "we're close to a price, pause" — lowering it again meant "not yet, keep trading."
