How Five Bankers Set the World Gold Price with Desk Flags
From 1919 to 2004, the international benchmark price for gold was decided twice each day inside a wood-paneled room at Nathan Mayer Rothschild & Sons in London. Representatives from five bullion banks sat around a table, each armed with a miniature wooden Union Jack flag. When the chairman proposed a price, bankers raised their flags to signal pending buy or sell orders. Only when all five flags were lowered did supply balance demand, fixing the world gold price.
The Gathering on St Swithin's Lane
On September 12, 1919, representatives of five major bullion dealing institutions met for the first time in the City of London at the headquarters of N M Rothschild & Sons on St Swithin's Lane. The British capital had long been the primary commercial crossroads for refined precious metals, but the aftermath of the First World War disrupted traditional currency relationships and gold flows. Market participants required a coordinated, universally recognized method to establish a single clearing price for physical gold bullion. The meeting established a formal ritual known as the London Gold Fixing, which went on to govern international gold transactions for the better part of a century.
The five founding members represented the elite of the British bullion establishment: N M Rothschild & Sons, Mocatta & Goldsmid, Pixley & Abell, Samuel Montagu & Co., and Sharps Wilkins. By tradition, the chair of the meeting was held by a partner or director from Rothschild. Every morning at 10:30 am, delegates gathered in person inside a quiet, wood-paneled room. Each representative sat at a personal desk equipped with a telephone landline connected directly to their firm's trading floor. Through these private telephone connections, the room acted as a funnel, gathering supply and demand interests from mining corporations, sovereign treasuries, commercial jewelers, and investors across the globe.
Flags, Telephones, and Price Discovery
The mechanism of the fix operated as an iterative clearing auction rather than a continuous market. At the start of the proceeding, the chairman announced a trial price in close proximity to the prevailing spot rate. The five delegates relayed this suggested figure to their dealing desks over their open telephone links. Dealers across each firm would rapidly aggregate customer orders alongside the bank's own inventory needs, tabulating the total quantity of gold their institution wished to buy or sell at that specific price. Each delegate then declared their position to the room as a net buyer or net seller, specifying the exact quantity of gold bars.
To manage the flow of the auction, each representative had a small wooden stand on their desk holding a miniature Union Jack flag. As long as any delegate raised their flag, the auction was frozen; a raised flag signaled to the chairman and fellow bankers that a dealer was still receiving orders, recalculating balances with their desk, or disputing the proposed price. The chairman could not finalize the fixing while a single flag remained upright. If aggregate buying interest exceeded selling interest, the chairman raised the proposed price; if sellers predominated, the price was lowered. Only when all five flags were lowered simultaneously—signifying that net demand matched net supply within an accepted margin—did the chairman strike a wooden gavel and declare the price fixed.
Adapting to Global Hours and Modern Currencies
For nearly half a century, the fixing occurred only once every business day and was conducted exclusively in British sterling. However, the international financial architecture shifted fundamentally during the mid-twentieth century. Following the expansion of the United States economy and the dominance of the US dollar in post-war international trade, the benchmark adapted. In 1968, the London market introduced a second daily fixing at 3:00 pm alongside the original morning session. This afternoon gathering was specifically timed to coincide with the opening of commercial financial markets in New York, giving North American market participants direct access to the London auction.
At the same time, the fixing shifted its primary quotation into US dollars, with additional equivalent calculations published in British pounds and, in later years, euros. Despite these operational adaptations, the core mechanics remained unchanged for decades. The face-to-face gathering at St Swithin's Lane continued through world economic crises, currency devaluations, and the dissolution of the Bretton Woods monetary system. Even as continuous electronic trading expanded across other financial commodities during the late twentieth century, the physical presence of the five delegates around Rothschild's table remained the world's standard method for pricing large physical consignments.
Why Global Commerce Relied on the Fix
The primary purpose of the London Gold Fixing was to solve a fundamental problem in physical commodities: how to transact immense volumes of metal without causing wild, disruptive price swings on open exchanges. In a standard continuous exchange, placing an order to purchase or liquidate hundreds of thousands of ounces of gold would cause sudden slippage, driving the price sharply against the party executing the trade. The fixing eliminated this friction by pooling buyers and sellers into a single clearing moment where all trades executed at the exact same price.
Because the mechanism matched supply and demand at an agreed equilibrium, central banks and multinational mining conglomerates used the London fix as the universal reference point in commercial contracts. A mining firm operating in South Africa, Australia, or the Americas could sign long-term supply agreements stipulating that production would be sold at the London morning or afternoon fix on the day of delivery. Commercial banks used the price to value collateral, refiners used it to settle accounts with smelters, and retail jewelers referenced it to price manufactured inventory, making the five delegates on St Swithin's Lane the central arbiters of the physical market.
The 2004 Transition and the End of an Era
The historic ritual began to unravel in the early 2000s as the structure of major investment banking changed. In April 2004, N M Rothschild & Sons announced it would withdraw from the gold fixing and exit commodity trading entirely, ending 85 years of presiding over the auction. Commercial commodity trading had evolved into high-volume, capital-intensive balance sheet operations dominated by global universal banks, and Rothschild opted to refocus its enterprise on sovereign and corporate advisory services. Rothschild's seat on the fixing was subsequently acquired by Barclays Capital.
With Rothschild's departure, the iconic morning and afternoon meetings inside the St Swithin's Lane wood-paneled room permanently ceased. In May 2004, the physical gathering was dismantled and replaced by a dedicated, private teleconference system connecting the five member banks—which at the time included Barclays, Deutsche Bank, HSBC, ScotiaMocatta, and Société Générale. While the iterative auction logic and the declaration of buy and sell interest remained, the ceremonial wooden Union Jack flags were abandoned in favor of verbal holds over the telephone network.
Regulatory Scrutiny and the Shift to Digital Platforms
Operating an opaque, private conference call among a tiny consortium of dominant financial institutions eventually invited intense criticism. In the wake of benchmark manipulation investigations across broader financial markets in the 2010s, regulators and industrial consumers questioned whether a teleconference run by five participant banks provided adequate transparency and protection against conflicts of interest. The private communication channel gave member dealers real-time insight into pending market order flows before the final price was published to the general public.
In response to regulatory pressures and market demands for independent oversight, the traditional London Gold Fixing was discontinued in March 2015. It was replaced by an electronic auction platform designated as the LBMA Gold Price, administered independently by ICE Benchmark Administration. Under the modernized system, the auction is fully electronic, algorithmic, and audited, accommodating a larger and more diverse group of direct participants. The transition closed the final chapter on an era where the foundation of the world's precious metal trade rested on five individuals signaling balances with wooden flags in a London dining room.
Key takeaways
•Established in 1919 at the London offices of N M Rothschild & Sons, the Gold Fixing met twice daily to match global supply and demand into a single clearing benchmark price.
•Delegates used miniature wooden Union Jack flags to halt the auction; the price could not be finalized until all five flags were lowered, confirming that buying and selling orders were in balance.
•The process shifted from British pounds to US dollars and added an afternoon session in 1968 to accommodate North American trading hours.
•Rothschild retired from the commodities business in 2004, ending the in-person flag ritual and paving the way for teleconference and eventual electronic auction systems.
