Gold Supply Chain Worldwide

This article is part of our complete guide to Gold Market Analysis. Explore the full series for everything from regional demand patterns to the role of the London Bullion Market. For the physical journey of gold from extraction through refining, see our guide, Gold Mining Supply Chain Explained.

Beyond the physical journey from mine to refinery, gold moves through a distinct global trading and market infrastructure — exchanges, bullion banks, clearing systems, and institutional vaults — that determines how gold is priced, traded, and settled around the world. This article focuses on that market-side supply chain, distinct from the extraction-and-refining process covered elsewhere in this series.

The Major Trading Hubs

A handful of global centers anchor the world's gold trading infrastructure:

• London — historically the center of the physical gold trade, home to the London Bullion Market Association (LBMA) and twice-daily gold price benchmarking, covered in more depth in our article on the role of the London Bullion Market.
• New York — home to COMEX, the dominant exchange for gold futures trading, covered further in our article on COMEX and gold futures explained.
• Shanghai — the Shanghai Gold Exchange has grown into a major physical trading hub, particularly significant for China's substantial domestic gold market.
• Zurich and Switzerland — a global center for gold refining and private vault storage, benefiting from Switzerland's long-standing reputation for financial security and neutrality.
• Dubai — an increasingly important trading and refining hub connecting Middle Eastern, South Asian, and African gold flows.

Bullion Banks: The Market's Connective Tissue

Bullion banks act as intermediaries throughout the gold trading system — facilitating transactions between miners, refiners, central banks, and institutional investors, providing financing, storage, and hedging services that keep physical gold moving efficiently between market participants. These institutions often hold significant gold inventories themselves and play a central role in maintaining market liquidity.

Physical Delivery vs. Paper Gold

Much of the modern gold market operates through "paper gold" — futures contracts, ETF shares, and other financial instruments representing gold ownership without requiring physical delivery of the metal itself. This layer of the market allows for vastly more trading volume and liquidity than the physical gold supply alone could support, though it also means that trading activity and price discovery don't always map directly onto physical supply and demand in the short term.

Central Banks as Both Participants and Reserve Holders

Central banks occupy a unique position in this supply chain — simultaneously major buyers (and occasional sellers) in the market and long-term holders of physical reserves, a role explored in depth in our existing coverage of central bank gold reserves. Their buying and selling decisions can meaningfully influence available market supply, distinct from the mine production side of the supply equation.

Refiners as the Bridge Between Mining and Trading

Refiners occupy a critical position connecting the physical mining supply chain to the trading infrastructure — converting raw and semi-refined gold into the certified, standardized bars that exchanges, vaults, and institutional buyers require, a process covered in detail in our article on security standards for gold refineries.

How Price Discovery Actually Happens

Gold's global price is effectively set through the interaction of this entire trading infrastructure — the London benchmark auctions, COMEX futures pricing, and Shanghai physical trading all feed into a continuously updated global price that reflects trading activity across time zones and market types, from pure financial speculation to genuine physical demand.

Why Understanding This Infrastructure Matters

For anyone trying to understand why gold prices move the way they do, recognizing that trading infrastructure and financial instruments — not just physical mine supply and consumer demand — play a major role in price formation is essential context. Much of the volatility and rapid price movement in gold markets stems from this financial trading layer, rather than sudden shifts in physical gold availability.
