Recycled Gold: The Hidden 30% of Global Supply

The headline numbers in gold markets focus on mine production, but mine output has been remarkably flat for over a decade. The variable that actually balances global supply and demand is recycled gold — the dental fillings, jewellery and electronics that flow back to refiners every year and represent a third of total supply.

The size of the flow

Recycled gold accounts for roughly 1,200 to 1,400 tonnes per year, against mine supply of around 3,600 tonnes. The ratio fluctuates with price: when gold rallies, recycling spikes as old jewellery enters the refining stream. When prices fall, the recycling tap closes quickly. This makes recycled supply more price-elastic than any other component of the market.

• Annual recycled gold: 1,200-1,400 tonnes
• Annual mine supply: ~3,600 tonnes
• Total annual supply: ~4,800-5,000 tonnes
• Largest recycling source: jewellery (~85%)
• Other sources: industrial, electronics, dental

Where the metal comes from

India is consistently the largest single source of recycled gold, driven by a deep tradition of gold-as-savings and the natural cycle of jewellery upgrades during weddings and festivals. Italy and Turkey are major secondary sources due to their refining and jewellery manufacturing infrastructure. The United States contributes through the "cash for gold" retail channel, particularly during economic stress.

How price affects recycling

Empirically, recycled supply rises about 200-300 tonnes for every 20% increase in gold price. The lag is short — typically 2-4 months. During the 2011 spike to $1,920, recycling jumped 18%. During the 2020 COVID rally, it rose 30%. The flow is one of the most reliable supply responses in any commodity market.

The cap on rallies

Recycled supply provides a natural ceiling on gold rallies that pure mine supply does not. A multi-year price doubling can pull 500-800 tonnes of additional recycled metal into the market — enough to absorb significant new demand without requiring large mine expansion. This is part of why gold rarely experiences true supply shocks.

What it means for forecasts

Long-term price targets that ignore recycling response are implicitly assuming that the elastic supply has run out. Most haven't. A $5,000 gold price would unlock recycling flows that would dwarf any current scenario, particularly from Indian household stocks estimated at over 25,000 tonnes.

Takeaway: Recycled gold is the silent stabiliser of the market. Forecasts that focus only on mining or central bank flows miss the most price-sensitive piece of the supply equation.
