Inside the World's Gold Vaults: Loomis, Brinks and the Fort Knox Question

Roughly 215,000 tonnes of gold have been mined in human history, and a remarkably small number of physical locations hold the institutional share. The companies behind those vaults — Loomis, Brinks, Malca-Amit, G4S and a handful of bank operators — run one of the most secretive and consequential industries in finance.

The London Vault Cluster

The Bank of England custody facility holds over 5,000 tonnes for sovereign clients. Surrounding it, the LBMA-accredited commercial vaults operated by HSBC, JPMorgan, Brinks, Loomis and Malca-Amit hold an additional 4,000 to 5,000 tonnes for ETFs, hedge funds and HNW clients. London moves more allocated gold than any other city on earth.

• Bank of England: ~5,400 tonnes for ~30 sovereign clients
• HSBC London: primary GLD custodian
• JPMorgan: largest COMEX-eligible vault operator
• Brinks Park Royal: major London commercial site
• Loomis: heavy in Switzerland and Singapore

Switzerland: the refining hub

Roughly 70% of the world's refined gold passes through Swiss refineries — Valcambi, Argor-Heraeus, Metalor and PAMP. That makes the Geneva Freeport and Zurich vault network a permanent transit point. Swiss bank vaults additionally hold significant private allocated metal outside the LBMA float.

"You can move a billion dollars of bonds with a keystroke. To move a billion in gold takes an armoured convoy and three weeks of paperwork. The friction is the feature." — vaulting executive, quoted in Reuters 2023

The Fort Knox question

The United States Bullion Depository at Fort Knox, Kentucky holds an officially declared 4,583 tonnes. It has not been comprehensively audited since 1953. Periodic political demands for an audit have produced limited inspections but never a full reconciliation. Whether the question is theatrical or substantive depends on who you ask, but the audit gap is real.

What private investors should know

Allocated storage at an LBMA vault, with serial-number-specific bars in your name, is the gold standard (literally) of physical ownership. Unallocated accounts are unsecured claims on a pool. If a custodian fails, the difference is everything.

Bottom line: The vault industry is the unseen plumbing that makes physical gold work as institutional money. Understanding which vault, under which legal regime, holds your bars matters more than most retail buyers realise.
