LBMA London Vault Holdings

What Is the LBMA?

The London Bullion Market Association (LBMA) is the international trade association that represents the wholesale over-the-counter market for gold and silver in London. London has been the center of global gold trading for over 300 years. The LBMA sets the globally recognized Good Delivery standard for gold and silver bars, operates the LBMA Gold Price and Silver Price auctions, and publishes monthly data on vault holdings and clearing activity.

London Vault System

LBMA vault holdings represent gold and silver stored in London vaults operated by seven custodians: the Bank of England, JP Morgan, HSBC, ICBC Standard Bank, Brink's, Malca-Amit, and Loomis. The Bank of England is the largest custodian, holding gold on behalf of central banks and commercial institutions. London vault data, published since July 2016, provides transparency into the physical metal underpinning the world's largest OTC bullion market.

Why LBMA Data Matters

London vault holdings are watched by traders and analysts as a barometer of Western institutional gold and silver demand. Declines in London vault gold, often coinciding with increases in COMEX registered inventory or Asian imports, can signal shifts in global metal flows. The clearing data, available since 1996, shows the volume and value of metal changing hands in London each month, reflecting overall market liquidity and activity levels.

LBMA Good Delivery List

The LBMA Good Delivery List is the gold standard for bar quality worldwide. It is a register of refiners whose gold and silver bars have been independently tested and accredited by the LBMA as meeting strict specifications for weight, dimensions, purity, and appearance. Only bars produced by Good Delivery refiners are accepted for settlement in the London bullion market, and the list is widely recognized by exchanges, central banks, and institutions globally.

Good Delivery gold bars must weigh between 350 and 430 troy ounces (approximately 10.9 to 13.4 kilograms) and have a minimum fineness of 995 parts per thousand. Good Delivery silver bars must weigh between 750 and 1,100 troy ounces (approximately 23.3 to 34.2 kilograms) with a minimum fineness of 999 parts per thousand.

The Good Delivery standard ensures liquidity and trust in the global bullion market. Because only accredited refiners can produce these bars, buyers and sellers can transact with confidence that the metal meets universally accepted quality criteria. This is a key reason London remains the world's preeminent center for wholesale bullion trading.

Data Sources & Methodology

The LBMA publishes London vault holdings data on a monthly basis, with approximately a one-month reporting lag. For example, January data is typically released in late February or early March. This delay is standard practice to maintain operational security while still providing market transparency.

The Bank of England holds a significant portion of the gold stored in London vaults, acting as custodian for approximately 30 central banks as well as commercial depositors. The remaining vault operators — JP Morgan, HSBC, ICBC Standard Bank, Brink's, Malca-Amit, and Loomis — hold metal on behalf of ETFs, institutional investors, and commercial clients.

Published data includes total gold and silver holdings in troy ounces but does not break down holdings by individual owner or custodian. MetalCharts tracks this data over time, presenting historical trends and month-over-month changes to help analysts and investors monitor shifts in London's physical metal inventory.
