Silver's double identity: monetary metal and industrial input
Understand where silver comes from, who uses it, why mine supply reacts slowly to price, and what a market deficit or surplus really tells you.
What you will learn
- The two sources of supply: mine output and recycling
- The main demand categories, from photovoltaics to coins, bars and exchange-traded products
- Why a by-product metal responds slowly to its own price
- How to read a supply–demand balance, and why a deficit is not a price forecast
Explanation
The Gold course compared silver with gold in general terms (lesson "Silver and Other Precious Metals"). Here we look at the physical market behind the price.
Silver has a double identity. It is a monetary metal, held as coins, bars and exchange-traded products like gold. It is also an industrial input: it conducts electricity better than any other metal and is used in solar cells, electronics and solders. Its price reacts to investors and to the factory cycle at once.
Supply: mines and recycling
A primary silver mine earns most of its revenue from silver. A by-product mine earns most of its revenue from lead, zinc, copper or gold and recovers silver along the way. According to the Silver Institute's World Silver Survey 2026 (prepared with the research firm Metals Focus), lead and zinc mines remained the largest source of mined silver in 2025, and global mine production rose by 3% to 846.6 million troy ounces (Moz).
Recycling (also called scrap supply) recovers silver from old jewellery, silverware, industrial waste and electronics. The same survey reports recycling of 197.6 Moz in 2025, a 12-year high. Recycling tends to rise when prices are high. Silver spread thinly through electronics is costly to recover.
Why by-product supply is "price-deaf"
A zinc mine plans its output around the zinc price; if silver rises, it does not dig more ore. New primary silver mines take many years to find, permit and build. Mine supply is therefore inelastic: quantity changes much less than price, so when demand jumps, the price does most of the adjusting.
Demand categories
Industry surveys group demand into these categories:
- Industrial: electronics, photovoltaics (PV, solar cells), brazing alloys, solders and other uses. Per the 2026 survey, industrial demand fell 3% to 657.4 Moz in 2025, out of total demand of 1.13 billion ounces: roughly 58%.
- Jewellery and silverware (cutlery, tableware).
- Physical investment: coins and bars, which rose by 14% in 2025 according to the same survey.
- Exchange-traded products (ETPs): securities backed by vaulted silver, usually shown as a separate line after the basic balance.
Industrial categories can change quickly. Solar manufacturers keep reducing the silver per cell (thrifting), and high prices speed this up. Trade press reports on the 2026 survey said PV silver use was expected to fall by about a fifth in 2026.
Deficit, surplus and above-ground stocks
The market balance is total supply minus total demand. A deficit means demand exceeded mine output plus recycling; a surplus means the opposite. The Silver Institute reported a deficit for the fifth consecutive year in 2025 and forecast a deficit of 46.3 Moz for 2026.
A deficit does not mean silver "runs out". The gap is filled from above-ground stocks: metal in London vaults, exchange warehouses, ETP vaults and private hands. A structural deficit (one lasting several years) draws these stocks down and can tighten the market, but stocks are large compared with one year's gap, and what matters is the price at which holders will sell. Surveys are also revised later. Treat a deficit as background, not as a timing signal.
Worked example
Hypothetical example: invented round numbers, not survey data.
Part A – the balance. Mine supply 830 Moz, recycling 180 Moz. Demand: industrial 650 Moz, jewellery 190 Moz, silverware 50 Moz, coins and bars 190 Moz.
- Total supply: 830 + 180 = 1,010 Moz.
- Total demand: 650 + 190 + 50 + 190 = 1,080 Moz.
- Balance: 1,010 − 1,080 = −70 Moz, a deficit.
- Deficit as a share of supply: 70 ÷ 1,010 ≈ 6.9%.
- Industrial share of demand: 650 ÷ 1,080 ≈ 60%.
Part B – the by-product effect. A zinc mine earns 85% of its revenue from zinc and 15% from silver. Silver rises 30%; zinc is unchanged.
- Revenue change: 15% × 30% = 4.5%.
- That is rarely enough to change a mine plan, so silver output stays roughly the same.
Costs and taxes are excluded.
Common mistake
Practice activity
Hypothetical data: mine supply 850 Moz, recycling 200 Moz; demand: industrial 680 Moz, jewellery 180 Moz, silverware 40 Moz, coins and bars 220 Moz. (a) Calculate the balance and express it as a share of supply. (b) Calculate the industrial share of demand. (c) A copper mine earns 10% of its revenue from silver. How does its revenue change if silver falls 40% and copper is unchanged?
Show solution
(a) Supply 850 + 200 = 1,050 Moz. Demand 680 + 180 + 40 + 220 = 1,120 Moz. Balance 1,050 − 1,120 = −70 Moz, a deficit of 70 ÷ 1,050 ≈ 6.7% of supply.
(b) 680 ÷ 1,120 ≈ 60.7%.
(c) 10% × (−40%) = −4%. Revenue falls only 4%, so the mine keeps producing silver.
Limitations: real balances contain more lines (such as producer hedging and ETP flows) and are revised.
Key takeaways
- Silver is both a monetary metal and an industrial input.
- Much mine supply is a by-product of lead, zinc, copper and gold mining and reacts little to the silver price.
- Industry is the largest demand category (roughly 58% in 2025, Silver Institute), but uses such as PV can shrink through thrifting.
- A deficit draws down above-ground stocks; it is context, not a price forecast.
