Central banks have bought about 1,000 tonnes of gold a year over the past four years, twice the average pace of the previous decade. The World Gold Council estimates that all 219,891 tonnes ever mined would fit inside a cube about 22 metres wide and amount to less than one troy ounce per person. Record mine production increased that stock by only 1.7% in 2025.
Jewellery holds 97,645 tonnes, or 44% of above-ground gold, more than investment products or central-bank reserves individually.
Mines added 3,672 tonnes of new gold in 2025, while recycling merely returned 1,404 tonnes of existing metal to the market.
Economic reserves total 54,770 to 64,000 tonnes, although the reserve-life calculation changes with the production estimate used.
The country with the largest gold vault is not the country with the most gold underground. The United States leads official holdings, while Australia leads mineable reserves.
The World Gold Council estimates that 219,891 metric tonnes of gold had been mined by the end of 2025, equal to about 7.07 billion troy ounces. Roughly two-thirds of that total was extracted after 1950, even though gold mining dates back thousands of years.
The figure is an estimate rather than a physical count, since ancient production was poorly recorded. Almost all mined gold still exists because it can be melted and reused without losing the metal, although some has been lost or remains uneconomic to recover.
Jewellery represents the largest share of above-ground gold.
| Gold form | Tonnes | Share |
|---|---|---|
| Jewellery | 97,645 | 44% |
| Bars, coins and ETFs | 50,978 | 23% |
| Central banks | 38,666 | 18% |
| Technology and other uses | 32,602 | 15% |
Jewellery contains more gold than bars, coins and ETFs, and more than twice the amount held by central banks.
That does not make all 97,645 tonnes readily available. A bullion bar can trade within minutes, while a wedding necklace may remain in the same family for generations and gold inside electronics may cost more to recover than it is worth.
Higher prices can bring old jewellery, coins and investment bars back to refineries. Personal attachment, central-bank policy and recycling costs still keep large quantities outside the active market.
Global mines produced a record 3,672 tonnes in 2025, only 1% more than in 2024. Even that output expanded the above-ground stock by just 1.7%.
Mining adds new gold to the global stock. Recycling returns metal already held in jewellery, coins, electronics and other products.
Recycled supply reached 1,404 tonnes in 2025, up only 3% despite sharply higher prices. Jewellery may carry emotional or cultural value, central banks follow long-term reserve policies, and private holdings can remain untouched for decades.
Recycling can respond within days once an owner decides to sell. A new mine must be explored, drilled, financed, permitted and built before production begins, a process that can take more than a decade.
Gold prices can jump in a day. Mine supply cannot.
Economic gold reserves total approximately 54,770 to 64,000 tonnes. Metals Focus estimates the lower figure, while the US Geological Survey places reserves near the top of the range.
At the 2025 mine-production rate of 3,672 tonnes, those reserves equal roughly 15 to 17 years of output. The number sounds like a deadline. It is not one.
Reserves include deposits that can be mined profitably under current prices, costs and technology. Gold may remain outside that total when its grade is too low, the deposit sits too deep, or the required infrastructure makes extraction too expensive.
A further 132,110 tonnes are classified as resources. Some may never be developed, while others can become reserves when drilling finds more ore, prices rise, or better processing improves recovery.
Higher energy, labour and financing costs can also push deposits out of the reserve category. The 15-to-17-year figure measures what can be mined economically today, not when the world will run out of gold.
Gold reserves by country can refer to official holdings owned by governments and central banks, or deposits considered economical to mine underground.
| Country | Official holdings |
|---|---|
| United States | 8,134 tonnes |
| Germany | 3,350 tonnes |
| Italy | 2,452 tonnes |
| France | 2,437 tonnes |
| China | 2,331 tonnes |
The United States holds more than twice as much official gold as Germany. Its lead reflects decades of monetary reserve policy rather than the size of its domestic deposits.
| Country | Underground reserves |
|---|---|
| Australia | 13,000 tonnes |
| Russia | 12,000 tonnes |
| South Africa | 5,000 tonnes |
| Indonesia | 3,600 tonnes |
| Canada | 3,200 tonnes |
Australia holds the largest estimated underground reserve, closely followed by Russia. Neither country leads the official-holdings ranking.
The country with the largest gold vault is not the country with the most gold left in the ground.
It is the best available estimate, not a physical count. Modern mine output is well documented, while ancient and informal production must be reconstructed from incomplete records. The World Gold Council updates the total as new annual data become available.
Gold occurs in the Earth’s crust at about 0.0013 parts per million on the Royal Society of Chemistry’s measure. Silver is roughly 42 times more abundant, while platinum is about 35 times less abundant than gold.
Geological rarity does not determine price alone. Production, recycling, industrial demand and investment demand also differ across the three metals.
No. Much of it remains in jewellery, official reserves, private holdings and technology. Only the portion owners are willing or able to sell becomes active market supply.
The world is unlikely to exhaust all underground gold on a fixed date. Current reserves cover deposits that are profitable to mine today, while prices, discoveries, costs and technology continually change which deposits qualify. The harder constraint is finding gold that can be developed economically and quickly.
A major discovery could transform a mining company or national industry without overwhelming the global market. Development often takes more than a decade, while the existing above-ground stock is already close to 220,000 tonnes.
The next annual stock update will show whether another strong mining year can lift above-ground supply by more than 2%. Central-bank demand can accelerate within months; new mine supply may take more than a decade to respond.
