Despite its enduring popularity, gold is relatively rare. According to the United States Geological Survey (USGS), a total of 187,000 metric tonnes (206,132 US tons) has been mined to date. All the gold discovered so far could actually fit in a cube 75 feet wide (23m) on each side. Considering there are 57,000 metric tonnes (62,832 US tons) left to extract, all the gold in the world amounts to 244,000 metric tonnes (268,964 US tons).
The 187,000 metric tonnes of gold that's been produced so far is worth over $16 trillion (£12.3tn). That's based on the price of the precious metal at the time of writing, which is over $2,700 (£2k) per troy ounce and has been soaring in recent months (more on that soon).
It's estimated that a further $5 trillion (£3.9tn) worth of gold is still waiting to be extracted, meaning all the gold in the world is worth approximately $21 trillion (£16.2tn). By way of comparison, the GDP of the US in 2024 stands at around $28.8 trillion (£22.2tn) and total US government expenditure for the 2024 fiscal year amounts to $6.75 trillion (£5.2tn).
