Silver faces a projected 46.3-million-ounce deficit in 2026, its sixth straight, because most silver is mined as a byproduct and can't scale up on its own.
At a glance
- The 2026 silver supply deficit is projected at 46.3 million ounces, which would be a sixth consecutive annual shortfall.
- 70-80% of global silver supply comes as a byproduct of copper, lead and zinc mining, not from dedicated silver mines.
- Byproduct mines can't simply increase silver output when prices rise, because investment decisions follow the primary metal's economics.
- Three separate August 2026 disruptions -- at Los Pelambres in Chile and Terronera in Mexico, plus a 9.0% production decline in Peru -- cut a combined 1.1 million ounces from supply.
What happened
Silver is on track for a sixth consecutive annual supply deficit in 2026, projected at 46.3 million ounces, following a confirmed fifth straight deficit in 2025 recorded in the Silver Institute's World Silver Survey 2026. The core reason the deficit persists even as silver prices have risen is structural: 70-80% of the world's silver supply comes not from dedicated silver mines but as a byproduct of mining copper, lead and zinc, according to industry data compiled by GoldSilver. Because those mines' investment decisions are driven by the economics of their primary metal, not silver, a higher silver price alone doesn't trigger more silver output. Recent disruptions have compounded the shortfall: Antofagasta's Los Pelambres copper mine in Chile cut production guidance on August 13, 2026, after a severe weather shutdown; a blockade at Endeavour Silver's Terronera project in Mexico began August 12 and didn't resume operations until August 24; and Peru posted a 9.0% year-on-year decline in silver production in June 2026. Crux Investor's compilation, published September 4, 2026, put the combined impact of just three August disruptions at 1.1 million ounces, roughly 2.4% of the full-year deficit on its own.
The details
The silver market's defining structural problem isn't a lack of silver in the ground -- it's that most of the silver that does get mined is a side effect of decisions made about entirely different metals. With 70-80% of global supply coming as a byproduct of copper, lead and zinc mining, the single biggest lever that normally fixes a commodity shortage -- a higher price pulling in more supply -- barely works for silver. A copper mine doesn't expand production because silver got more expensive; it expands, or doesn't, based on copper economics, and whatever silver comes along with that ore is almost incidental to the investment decision.
Oliver Turner, an executive at Americas Gold & Silver, has pointed to exactly this dynamic playing out in the disruptions that hit the market in August 2026: byproduct mines are exposed to supply-chain and operational problems tied to their primary metal, and when those problems hit, the silver that would have come along for the ride simply doesn't show up either. Antofagasta cutting guidance at Los Pelambres because of severe weather, a community blockade halting Endeavour Silver's Terronera project for twelve days, and a 9% year-on-year output decline in Peru weren't three unrelated events -- they're the same underlying vulnerability showing up in three different mines in the same month.
On the other side of the ledger, demand keeps climbing for reasons that have nothing to do with silver's traditional jewellery and coin-buying base. Industrial uses -- solar panels, electronics, electric vehicles -- now account for 50-55% of total annual silver demand, a share that has grown steadily as solar installation and EV production have scaled up worldwide. That demand doesn't pull back just because supply is tight; it's driven by manufacturing schedules and installed-capacity targets set well in advance. A market with inelastic, byproduct-dependent supply on one side and structurally growing industrial demand on the other is exactly the setup that produces a persistent, multi-year deficit rather than a one-off shortage that self-corrects.
Why it matters
For anyone trying to understand why silver's price keeps behaving differently from what a simple supply-demand chart might suggest, the byproduct-mining mechanism is the single most important fact to know. It means silver's fifth and now likely sixth straight annual deficit isn't a temporary imbalance waiting for producers to respond to price -- it's a structural feature of how silver is actually mined. That has direct implications for anyone holding silver, buying it industrially, or trying to forecast where the price goes next: the usual assumption that higher prices solve shortages doesn't hold here the way it does for commodities with dedicated primary producers.
Our read
Outlook: bullish. A structurally persistent, multi-year supply deficit with inelastic byproduct-driven supply and growing industrial demand is a fundamentally supportive setup for silver prices over time, even though near-term price moves depend on many other factors.
What to watch
- Whether the Silver Institute confirms a sixth consecutive annual deficit once full-year 2026 data is finalized
- Operational updates from Antofagasta's Los Pelambres and Endeavour Silver's Terronera project
- Peru's monthly silver production trend after June 2026's 9.0% year-on-year decline

- 2026-08-13: Antofagasta cuts production guidance at its Los Pelambres copper-silver mine in Chile after a severe weather shutdown.
- 2026-08-24: Operations resume at Endeavour Silver's Terronera project after the twelve-day blockade.
- 2026-09-04: Crux Investor publishes a compilation putting the combined impact of the August disruptions at 1.1 million ounces.
Demand Drivers
Industrial demand -- primarily solar panel manufacturing, electronics and electric vehicles -- now accounts for 50-55% of total annual silver demand, a structurally growing share that doesn't respond to short-term price moves the way discretionary jewellery or coin buying does.
Supply Drivers
70-80% of global silver supply is produced as a byproduct of copper, lead and zinc mining, meaning silver output is set by decisions made about those primary metals' economics rather than by silver's own price -- the core reason the market can run a supply deficit for multiple consecutive years without self-correcting.
Mining Production
August 2026 alone saw three separate byproduct-mine disruptions -- Antofagasta's Los Pelambres guidance cut on August 13 after severe weather, a twelve-day blockade at Endeavour Silver's Terronera project starting August 12, and a 9.0% year-on-year production decline in Peru for June 2026 -- together removing a combined 1.1 million ounces, about 2.4% of the projected full-year deficit.
What could lift prices
- A sixth consecutive annual deficit, if confirmed, would extend one of the longest sustained supply shortfalls silver has seen.
- Structurally growing industrial demand (50-55% of the total) doesn't retreat the way discretionary demand can when prices rise.
- Byproduct-dependent supply structurally cannot respond quickly to price incentives, removing the usual self-correcting mechanism.
What could weigh on prices
- The August 2026 disruptions cited add up to only 1.1 million ounces, a small fraction of the 46.3-million-ounce projected annual deficit, so their direct price impact is limited.
Country impact
| Country | Impact | Reason |
|---|---|---|
| Chile | Medium | Antofagasta's Los Pelambres copper-silver mine cut production guidance in August 2026 after a severe weather shutdown, reducing byproduct silver output. |
| Mexico | Medium | A community blockade halted Endeavour Silver's Terronera project for twelve days in August 2026. |
| Peru | Medium | Peru, a major silver-producing country, posted a 9.0% year-on-year decline in silver production in June 2026. |
Industry impact
| Industry | Effect | Reason |
|---|---|---|
| Solar Manufacturing | Negative | A persistent silver supply deficit raises input-cost risk for solar panel makers, who rely on silver paste in photovoltaic cells. |
| Copper Mining | Neutral | Byproduct silver output is a secondary revenue stream for copper miners, but their core investment decisions remain driven by copper economics, not silver's deficit. |
Who gains, who loses
- Primary silver miners with limited byproduct exposure: Companies with dedicated silver operations are less exposed to the base-metal economics that constrain byproduct producers, giving them more direct leverage to a persistent deficit.
- Solar panel and electronics manufacturers: A persistent, structurally hard-to-fix supply deficit raises long-term input cost and availability risk for industries that depend on a steady silver supply.
Other ways this could play out
- A slowdown in copper, lead or zinc mining investment for reasons unrelated to silver could unexpectedly deepen the byproduct silver shortfall further.
- A resolution of the Terronera blockade and stabilization at Los Pelambres could keep the 2026 deficit closer to the 46.3-million-ounce projection rather than widening further.
Price risks
- Further unplanned disruptions at byproduct-heavy copper, lead or zinc mines could widen the deficit beyond the current 46.3-million-ounce projection
- Because supply can't respond quickly to price, sharp industrial demand swings (solar installation booms, EV production surges) could translate into outsized price moves in either direction
Historical comparison
- 2025: Silver recorded its fifth consecutive annual supply deficit, per the Silver Institute's World Silver Survey 2026.
- 2026 (projected): The deficit is projected at 46.3 million ounces, which would extend the run to six consecutive years if confirmed.
