The Industrial Supply Case for Silver and Platinum Investment

Silver has run a physical supply deficit for six consecutive years. Platinum recorded a shortfall of more than a million ounces just last year. And yet, in most institutional portfolios, both metals remain a rounding error next to gold.

That gap between what the supply data shows and how the market is positioned is the story. Structural shortfalls that accumulated quietly through the early 2020s are now colliding with two demand catalysts that did not feature in any prior commodity cycle: solid-state battery architecture and the buildout of AI infrastructure.

This is not a monetary metals argument. It is an industrial supply argument with investment implications, and what follows lays out the specific supply and demand data you need to judge whether silver and platinum investment belongs in a commodity-cycle allocation, along with the material risks to weigh before you act.

Six years of deficit and the supply ceiling silver cannot break through

The silver market has been short physical metal every year from 2021 through the 2026 forecast. That is not a one-off dislocation. It is a pattern long enough to have drawn down above-ground inventories in a market small enough to feel it.

The numbers tell the story of a gap that is widening, not closing. The 2025 physical deficit came in at 40.3 Moz, with demand of roughly 1,130.6 Moz against supply of 1,090.4 Moz. The 2026 forecast pushes that shortfall out to 46.3 Moz.

Stack those annual shortfalls together and the scale becomes clearer.

The cumulative drawdown The combined deficit from 2021 through the 2025/2026 period exceeds 762.1 Moz, close to a full year of global mine output. That is inventory removed from the system that cannot be replaced on a short timescale.

Why higher prices cannot unlock more silver supply

Here is the mechanical reality that separates silver from most other commodities. Roughly 74% to 75% of the world’s mined silver comes out of the ground as a byproduct of copper, lead, zinc, and gold mining, not from mines dug specifically for silver.

That matters because a copper miner decides whether to expand based on copper prices and copper margins. The silver that comes with it is incidental. A higher silver price does not, on its own, prompt anyone to break new ground.

Global mine production rose only modestly in 2025 to 846.6 Moz, and the growth that did occur came from byproduct copper output in Peru and the ramp-up of Polymetal’s Prognoz mine in Russia. No significant new high-grade primary silver discoveries have entered the production pipeline.

The constraint compounds from there. Copper operations depend heavily on sulfuric acid, and its availability is declining while its cost rises. That squeezes the economics of the very copper mines that incidentally produce most of the world’s silver.

For an investor, this is the single most important structural fact in the analysis. You cannot assume higher prices will call forth new supply the way they would for a primary-mined commodity. The deficit is not correcting itself through normal market clearing, which is exactly what distinguishes the structural case from a momentum trade.

Structural metal deficits that resist price-driven correction are not unique to silver; copper and uranium face analogous supply inelasticity, where the mechanism that would normally call forth new production is broken by long lead times, byproduct extraction economics, or concentrated jurisdiction risk.

What solid-state batteries and AI infrastructure mean for demand that did not exist last cycle

If supply is stuck, the question becomes what happens to demand. And this is where two entirely new end-use categories enter a market already running short.

The first is solid-state EV batteries. The silver-carbon (Ag-C) composite anode design being developed for these cells is not an incremental change in silver intensity. It is a step-change, and the numbers make the point on their own.

• Conventional lithium-ion EV: approximately 25-50 grams of silver per vehicle
• Solid-state Ag-C architecture: approximately 1,000 grams (roughly 32 troy ounces) per 100 kWh pack

That is a difference of more than twentyfold per vehicle. Samsung is targeting full-scale solid-state battery production by mid-2027, which puts a near-term date on when this demand could begin to register.

Run the scenario and the scale becomes hard to ignore. If solid-state batteries reach a 20% adoption rate across roughly 16 million EVs produced annually, silver demand from that channel alone could reach approximately 16,000 metric tonnes. That is more than half of current global mine output of around 25,000 tonnes per year.

[The scenario is precisely that, a scenario. Adoption rates are unproven, and ongoing engineering work to cut silver intensity per pack or shift to hybrid anode designs could cap the upside meaningfully. Treat the figure as quantified potential, not a forecast.]

For investors wanting to stress-test the adoption assumptions in detail, our full explainer on the silver solid-state battery thesis examines the engineering timelines, competing anode chemistries, and probability-weighted demand scenarios that determine whether the 20x intensity multiplier translates into sustained market pressure.

The second catalyst sits on the platinum side. AI infrastructure, hyperscale data centres, and modern industrial hardware require platinum group metals (PGMs) for high-reliability connectors, sensors, and specialised catalysts, a demand source diversifying away from the traditional automotive market.

Current AI-related PGM demand is estimated at 200,000 to 400,000 ounces per year. The growth trajectory is where the interest lies.

A fivefold projection Valterra Platinum estimates that AI-related PGM demand could reach 1 to 2 million ounces annually by 2030, roughly a fivefold increase on current levels. As with the battery scenario, this is a forward estimate, not a committed volume.

Not every demand signal points up. Industrial silver demand actually fell 3% in 2025 to 657.4 Moz, partly because high prices are forcing thrifting in solar PV applications where manufacturers use less metal per panel.

The read for an investor is this. The solid-state scenario, even at partial adoption, would add a demand source larger than the current annual deficit in a market that cannot expand supply quickly. If you modelled silver demand on solar and industrial use alone, you were working from an incomplete picture.

Platinum’s supply picture and why the deficit-surplus debate is more nuanced than the headlines suggest

Platinum’s supply story does not resolve as neatly, and the disagreement between forecasters is itself worth understanding.

The recent deficits are well documented. The World Platinum Investment Council (WPIC) and Johnson Matthey recorded a 598,000-ounce deficit in 2024. In 2025, the full-year shortfall reached 1,082 koz, with Q1 2025 alone recording an 816 koz deficit as total supply fell 10% year-over-year to 1,458 koz.

That final row is the twist. WPIC’s latest guidance reverses the deficit trend and forecasts a 265,000-ounce surplus for 2026, the first annual surplus since 2022. Q2 2025 data already hinted at the pivot, showing a near-balanced market with an 11 koz deficit.

Whichever supply scenario plays out, the concentration risk does not go away.

• South Africa: The dominant producer, exposed to power supply constraints and operational disruption
• Russia: Supply subject to geopolitical and sanctions-related uncertainty
• Zimbabwe: A smaller but material contributor facing its own operational challenges

Together these three countries supply over 90% of primary PGM output.

South African PGM supply risk operates at a geological level that sits beneath the headline operational and power-grid disruptions, with declining ore grades in aging Bushveld Complex mines compounding the above-ground political and infrastructure vulnerabilities that most supply forecasts only partially price in.

The 2026 surplus forecast and what would have to break for it to be wrong

The WPIC surplus rests on two assumptions: that investment demand steps down, and that recycling supply partly recovers.

Pull either assumption and the surplus collapses. If investment demand rebounds instead of falling, or if autocatalyst recycling disappoints, the balance tips back toward deficit.

Then there is geopolitics. A Russian or South African supply disruption could flip the market balance with limited warning, which means the surplus forecast is more fragile than a single headline number suggests.

The interpretive point for positioning is this. The surplus does not dissolve the investment case. It shifts the tactical question from “is supply short now” to “what disrupts the surplus scenario,” and supply concentrated in three politically exposed producers is the most direct answer to that question.

Pricing, volatility, and the risks that undercut a straightforward thesis

Structural deficits are necessary for a bullish case. They are not sufficient. Understanding what could go wrong is what separates a defensible thesis from a promotional one.

Start with where prices sit. As of late September 2026, silver traded at approximately $65.80 to $66.50 per troy ounce (Bloomberg reference $66.17), and platinum at approximately $1,798 to $1,805 per troy ounce (Bloomberg reference $1,805.09). Those are the levels against which any entry point has to be judged.

The bigger near-term risk is the macro override. Interest rates and dollar strength frequently dominate commodity price action over short horizons, independent of what supply and demand are doing underneath.

The macro dampener A multi-year supply deficit does not guarantee straight-line price appreciation. Macroeconomic variables can delay the price signal for far longer than a fundamental read alone would predict.

The metal-specific risks deserve equal clarity.

Silver risks:

• Industrial demand fell 3% in 2025 to 657.4 Moz, partly from thrifting in solar PV applications
• Western physical investment demand dropped 22% in 2024 as investors took profits
• Solid-state battery demand is scenario-based; reduced silver intensity per pack or hybrid anode designs could cap the upside

Platinum risks:

• The 2026 WPIC surplus of 265,000 ounces is itself a headwind to a bullish thesis
• Stronger-than-expected recycling recovery would loosen the market further
• Efficiency gains in data-centre hardware could limit PGM intensity and cap the AI demand narrative

The takeaway is not that the thesis fails. It is that knowing precisely what would have to break, and under what conditions each bullish scenario unwinds, puts you in a better position to size exposure and set entry criteria than acting on the deficit story alone.

What the supply data actually argues for, and where the uncertainty sits

The two metals are not interchangeable precious-metals plays, and treating them as one misreads what drives each.

Silver’s case rests on supply inelasticity, the byproduct constraint that stops higher prices from unlocking new metal, layered with genuinely new demand-category risk from solid-state batteries. Its starting condition is a six-year run of physical deficits.

Platinum’s case is different. It rests on supply concentrated in three politically exposed producers and the fragility of the WPIC’s 2026 surplus assumptions, coming off the deep deficits of 2024 and 2025.

For an investor evaluating whether, and how much, to allocate, the useful output is not a verdict but a set of observable signals to track over the next 12 to 24 months.

1. Solid-state battery production milestones: Watch Samsung’s progress toward its mid-2027 target as the clearest near-term test of the silver demand scenario
2. PGM demand data from AI infrastructure: Track whether reported figures move toward Valterra Platinum’s fivefold projection or stall short of it
3. The WPIC surplus assumptions: Monitor investment demand and recycling recovery, the two variables holding up the 2026 platinum surplus
4. Supply disruptions in South Africa and Russia: Any material interruption from either producer could flip the platinum balance quickly

Each metal offers a distinct risk-return profile, and the conditions that validate one do not automatically validate the other. That is the framework worth carrying into the decision.
