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, Visual Capitalist’s Jeff Desjardins notes that 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.
