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.
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."
