Six Years of Silver Deficit and What It Means for Primary Developers

The silver market has run a supply shortfall for five consecutive years, and the arithmetic is now hard to ignore: a cumulative deficit of 762 million ounces between 2021 and 2025, according to the World Silver Survey 2026. This is not a temporary imbalance waiting for the next production quarter to correct. It is a structural dislocation between an industrial transformation and a supply base that cannot geologically keep pace.

The core of that transformation sits in solar. Photovoltaic demand for silver grew by 110% between 2021 and 2025, one of the sharpest single-sector demand shifts the market has seen. Supply, by contrast, has barely twitched, because roughly three-quarters of global silver output is a byproduct of mining other metals and does not respond to the silver price. That leaves the entire swing supply function to a narrow cohort of primary silver developers, who account for only about 26% of global mine output, just as Colombia opened a significant regulatory door in September 2026.

That convergence of a commodity deficit and a jurisdictional reset is the subject here. What follows builds the case from first principles, so you can judge the opportunity on its structural merits rather than the promotional narrative around it.

Five years of deficit and why the silver market cannot fix itself quickly

Start with demand, because that is where the pressure originates. Fabrication demand, led by electronics and photovoltaics, has outpaced mine supply and recycling year after year. The 110% surge in solar-linked silver demand between 2021 and 2025 is the clearest single expression of that pull, and it shows no sign of reversing as global deployment continues.

Industrial fabrication demand spans a broader set of end markets than solar alone, including electrical contacts, soldering alloys, and high-frequency electronics, each of which adds incremental pressure to a supply base that is already structurally constrained.

Now put the supply response next to it. The market recorded a physical deficit of 40.3 million ounces in 2025, the fifth consecutive year demand exceeded supply, per the World Silver Survey 2026. Metals Focus forecasts a sixth deficit of 46.3 million ounces for 2026, against demand of 1,112.6 million ounces and supply of 1,066.4 million ounces.

The Silver Institute supply and demand data, compiled annually through the World Silver Survey, shows fabrication demand consistently outpacing mine supply and recycling across multiple consecutive years, providing the foundational benchmark against which deficit forecasts are measured.

There is a cyclical caveat worth naming. The 2025 deficit was smaller than preceding years, partly on softer fabrication demand, which tells you the shortfall is sensitive to global manufacturing and solar installation rates. A sharp manufacturing slowdown could narrow or briefly close the gap.

762 million ounces The cumulative supply-demand deficit from 2021 to 2025. Elevated prices did not close it.

But direction of travel over five years is unambiguous. Here is the analytical signal that matters most: silver traded between $66.54 and $67.00 per troy ounce on 18 September 2026, and the market is still forecast to run a sixth straight deficit at those levels.

Elevated prices alone have not rebalanced this market. That points to the supply-side structure, not price, as the binding constraint. If you are treating silver as a short-cycle commodity trade, you are reading the wrong signal, because the tailwind here is structural rather than cyclical.

The 74% problem: why most of the world’s silver cannot respond to price

To understand why price has not fixed the deficit, follow the ore. Most silver does not come out of the ground because someone went looking for silver. It comes up alongside lead, zinc, copper, and gold, as a secondary output of mines built around a different metal entirely.

That distinction sits at the heart of everything. Consider where byproduct silver actually originates:

• Lead and zinc mines, where silver is recovered from the same polymetallic ore bodies
• Copper mines, where silver reports alongside the primary copper concentrate
• Gold mines, where silver is a secondary credit to gold production

At each of these operations, the decision to expand output is driven by the economics of the host metal. When silver rallies, it improves the margin on a zinc or copper mine, but it does not persuade the operator to dig more, because the business case was never about silver in the first place. Elevated silver prices affect margins, not volumes.

Byproduct supply constraints compound the problem because they are largely invisible in price signals: a zinc mine running at full capacity in response to zinc economics looks identical to a silver supply squeeze from the outside, even though the two situations have completely different remediation paths.

Put a number on it and the constraint becomes obvious. Around 74% of global silver mine supply is byproduct output, according to figures tied to the World Silver Survey 2026, leaving only about 26% as primary silver production that actually responds to the silver price.

This is the discovery the mechanism forces on you. A silver price rally does not unlock a proportionate supply response, because three-quarters of the supply base is deaf to the signal. That is precisely the condition under which the small cohort of primary silver developers becomes strategically significant.

It also gives you an analytical distinction worth keeping. A silver-exposed base-metal producer and a primary silver developer are genuinely different investment categories, with different supply-side roles and different sensitivities to the silver price. Conflating them is a common error.

Can sustained high prices unlock new primary supply?

The obvious counterargument is that prices in the mid-$60s to low-$70s will eventually pull new primary supply into the market. In theory, yes. A minority of analysts make exactly this case.

The problem is time. A greenfield primary silver project typically runs through exploration, permitting, financing, and construction before ounces reach the market. The price signal today does not become supply for the better part of a decade.

That lag is not a flaw in the thesis. It is the opportunity window for early-stage capital, because the supply response that could eventually close the deficit is years away from arriving.

What Colombia’s September 2026 regulatory reset means for silver development capital

Something genuinely new happened in September 2026, and it changes the calculus for a jurisdiction that capital had largely written off. The Colombian government repealed ten restrictive mining resolutions, rules that had frozen certain areas for periods of up to a decade, according to company and government disclosures reported through Outcrop Silver and Gold Corporation.

Alongside the repeal, the government set a target of $4 billion in mining sector investment through 2030, supported by faster permitting and stronger investor protections.

$4 billion investment target through 2030 A jurisdiction that rationally excluded capital is now signalling it wants that capital back.

A note on verification is warranted here, and you should treat it as part of the analysis rather than a footnote. Independent confirmation of these reforms from named official government documents was not available in accessible sources. The figures come from company and government disclosures as reported.

With that caveat in place, the jurisdictional credibility does not rest on the policy alone. The Mariquita mining district has documented mining activity stretching back to 1585, and the region hosts active operations today, including Aris Mining’s Segovia and Marmato mines. This is not a frontier being tested for the first time.

The permitting path is also legible, which matters for pricing risk. Colombian projects move through four stages across two authorities.

Projects already holding an exploration-stage mining title have removed one layer of that uncertainty. For you, the read is this: capital that was rationally excluded now faces a different risk-adjusted calculation, and jurisdictional inflection points are among the least-priced adjustments in resource investing. September 2026 gives you a temporal reference for when re-rating of qualifying assets could begin.

How primary silver developers get re-rated: the milestones that move valuation from ounces to NPV

Most developers today are valued on ounces in the ground, at steep discounts to net asset value. That discount reflects permitting risk, capital cost inflation, and execution risk. Understanding how a project climbs out of that discount is the practical core of any evaluation.

History points to three milestones that shift institutional capital from per-ounce metrics toward NPV and discounted cash flow (DCF) models, where value is based on projected future cash flows rather than in-situ metal.

1. A credible feasibility-level study, demonstrating compelling economics such as low all-in sustaining costs and a strong net present value at conservative price assumptions.
2. Major permits and community agreements in place, often the single largest catalyst for generalist capital to apply full valuation multiples.
3. Financing substantially secured, through debt, streams, royalties, or strategic equity, which removes the funding-risk overhang.

Grade quality is what makes a developer worth tracking through those milestones in the first place. Outcrop Silver and Gold Corporation reports an Indicated resource grade of 518.7 g/t AgEq at its Santa Ana project, which it benchmarks among the highest of any publicly disclosed primary silver development. Its stated peer group for grade comparison includes Blackrock Silver, Silver47, Contango Silver and Gold, Vizsla Silver, and Argenta Silver.

Management, in the person of CEO Rob Bruggeman, has targeted a valuation re-rating toward an NPV and DCF framework within 6 to 12 months of September 2026. Treat that as a management target, not a guaranteed outcome. The three prerequisites above are the variables to track against it.

What the pitfalls look like in practice

The re-rating path runs both ways. Projects that have advanced can be pushed back into discount-to-NAV territory when execution disappoints. The recurring failure modes are worth holding as parallel risks:

• Capital cost overruns and construction delays relative to feasibility projections, which frequently reset even advanced-stage valuations to heavily discounted levels.
• Metallurgical underperformance, where recoveries or grades come in below modelled levels, eroding NPV and damaging management credibility well into production.
• Permitting reversals or social-licence conflicts, which can push institutional capital back to option-value thinking regardless of grade quality.

For you, this converts a vague sense of “early-stage risk” into a checklist. Knowing where a project sits on the de-risking curve lets you calibrate position sizing rather than treating every developer as equivalent.

Assessing the convergence: what to watch before committing capital

The structural thesis is documented. The investment thesis, though, only resolves when specific milestones are reached, and tracking them is the active work. Three macro variables tell you whether the deficit keeps tightening: solar PV deployment as the demand driver, recycling supply as the partial offset, and base-metal market conditions as the signal for whether byproduct supply grows independently of the silver price.

Three project-level variables tell you whether a specific developer is de-risking: progression through permitting, particularly the environmental licence at Colombia’s regional authority level; feasibility study completion and its economics; and the structure of any financing milestone.

The timing is genuinely specific. The Colombian reform is a September 2026 event, the deficit is in its sixth forecast year at 46.3 million ounces, prices sit near $67 per ounce, and management has flagged a 6-to-12-month re-rating window against Colombia’s $4 billion investment backdrop.

Sixth consecutive deficit, forecast at 46.3 million ounces for 2026 Price alone has not been enough to rebalance supply. That is the whole point.

The combination creates a window, not a guarantee. If you can separate the structural thesis from the project-execution variables, you are better positioned to tell a genuine re-rating catalyst apart from promotional noise.

The structural thesis holds; the execution variables are what matter now

Three layers stack up here, and they reinforce each other. A persistent structural deficit of 762 million ounces over five years, driven by a supply base that is roughly 74% price-inelastic byproduct output. A September 2026 regulatory opening in a jurisdiction with silver mining history dating to 1585. And a narrow cohort of high-grade primary developers positioned to absorb re-rating capital.

The risk layer is equally real. Company-reported regulatory claims still require independent verification as official documentation becomes available, project timelines are management targets rather than guaranteed outcomes, and the commodity backdrop remains sensitive to global manufacturing and solar deployment cycles.

So the evaluative posture is straightforward. The structural conditions for a re-rating of qualifying primary silver developers are well-supported, but the case resolves only at the project level, against three milestones:

• A completed feasibility study with strong economics
• Major permits and community agreements in place
• Financing substantially secured

Track those, and you are judging the opportunity on its merits.
