Transparency in the over-the-counter (OTC) gold and silver markets in London is improving. Indeed, for the first time in history, we now have a “window” into the bullion vaults in London.
At the end of July, the London Bullion Market Association (LMBA) started publishing, with a delay of three months, figures for the gold and silver bullion held in those London vaults offering custodian services.
As at March 31, there were 7,449 tonnes of gold, valued at $298 billion and 32,078 tonnes of silver valued at $19 billion. This is the equivalent of approximately 596,000 gold bars and 1,069,255 silver bars.1
Gold – Troy Ounces

Source: LBMA. Notes: a) End of month figures; b) held within the environs of the M25 (large motorway around London); c) All physical forms of metal: large wholesale bars, coin, kilo bars, and small bars; d) Only includes physical metal held within the London environs; e) Jewelry and private holdings not included; and f) 1 gram = 0.0321507465 troy ounces.
In an even more historic move, the LBMA will be following up by reporting trade data, thereby providing “gross turnover for the Loco* London market.”2 London is the largest gold trading center in the world. On average each day in March this year $18 billion of gold was cleared in London. In 2015, 310,358 tonnes (10 billion ounces) of gold were traded globally. The London OTC market amounted to 144,000 tonnes, or 46.3%, of the gold traded, while the New York futures market accounted for 130,350 tonnes or 42.0%.
