Roughly a quarter of annual gold supply comes from recycling, the fastest-moving lever in an otherwise glacial supply chain. Unlike mine output, it responds to price within weeks, concentrated in markets with deep household holdings and accessible refining: India, Turkey, Thailand and southern China.
Each sharp rally therefore triggers a supply response that mine schedules cannot provide, which is one reason gold rallies flatten faster than the demand data alone would suggest.
The speed of this supply response is structural rather than cyclical. Household gold in these markets is typically held in jewellery form with minimal numismatic premium, meaning it can be sold back into the refining chain at close to metal value with little friction, unlike, say, coin collections or industrial inventory that carry switching costs.
