An Inside Look at the World’s Biggest Paper Gold Market

Published

on

Every day, there are a whopping 5,500 tonnes ($212 billion) of gold traded in London, making it the largest wholesale and over-the-counter (OTC) market for gold in the world.

To put that in perspective, more gold is traded in London each day than what is stored at Fort Knox (4,176 tonnes). On a higher volume day, amounts closer to total U.S. gold reserves (8,133.5 tonnes) can change hands.

How is this possible?

The infographic below tells the story about gold’s foremost trading hub, as well as the paper gold market in London, England:

London is dominant in global price discovery for gold.

In 2015, it accounted for roughly 88% of gold trade – most of which occurs between banks on behalf of their clients. Further, 90% of London trade is spot trading, which further emphasizes London’s importance in price discovery for gold markets.

While the high-level details of the market are visible, the individual mechanisms behind the London gold trade are less clear. There is very little detailed information provided on physical shipments, outstanding gold deposits or loans, allocated or unallocated gold, or clientele types. Trade reporting also breaks down at a more granular level, and datasets on the GOFO (Gold Forward Offered Rate) were also discontinued in January, 2015.

Almost all gold (95%) traded in London is unallocated and without legal title. This makes it easier to trade, but it also raises concerns about a market that is opaque to begin with. There are 5,500 tonnes of paper gold exchanging hands on paper each day, but there are only 300 tonnes of gold vaulted in London outside of the reserves for ETFs or the Bank of England.

What would happen if there was ever even a small rush to get the physical asset behind the paper? Is there a system in place for such an event, and how does it work?

Uranium

Charted: Global Uranium Reserves, by Country

We visualize the distribution of the world’s uranium reserves by country, with 3 countries accounting for more than half of total reserves.

There can be a tendency to believe that uranium deposits are scarce from the critical role it plays in generating nuclear energy, along with all the costs and consequences related to the field.

But uranium is actually fairly plentiful: it’s more abundant than gold and silver, for example, and about as present as tin in the Earth’s crust.

We visualize the distribution of the world’s uranium resources by country, as of 2021. Figures come from the World Nuclear Association, last updated on August 2023.

Ranked: Uranium Reserves By Country (2021)

Australia, Kazakhstan, and Canada have the largest shares of available uranium resources—accounting for more than 50% of total global reserves.

But within these three, Australia is the clear standout, with more than 1.7 million tonnes of uranium discovered (28% of the world’s reserves) currently. Its Olympic Dam mine, located about 600 kilometers north of Adelaide, is the the largest single deposit of uranium in the world—and also, interestingly, the fourth largest copper deposit.

Despite this, Australia is only the fourth biggest uranium producer currently, and ranks fifth for all-time uranium production.

Figures are rounded.

Outside the top three, Russia and Namibia both have roughly the same amount of uranium reserves: about 8% each, which works out to roughly 470,000 tonnes.

South Africa, Brazil, and Niger all have 5% each of the world’s total deposits as well.

China completes the top 10, with a 3% share of uranium reserves, or about 224,000 tonnes.

A caveat to this is that current data is based on known uranium reserves that are capable of being mined economically. The total amount of the world’s uranium is not known exactly—and new deposits can be found all the time. In fact the world’s known uranium reserves increased by about 25% in the last decade alone, thanks to better technology that improves exploration efforts.

Meanwhile, not all uranium deposits are equal. For example, in the aforementioned Olympic Dam, uranium is recovered as a byproduct of copper mining occurring at the same site. In South Africa, it emerges as a byproduct during treatment of ores in the gold mining process. Orebodies with high concentrations of two substances can increase margins, as costs can be shared for two different products.
