The Silver Supply Squeeze: Why a 67:1 Gold-Silver Ratio May Be Vulnerable to Compression An Evidence-Based Framework for Understanding Silver’s Physical Market

The Silver Supply Squeeze: Why a 67:1 Gold-Silver Ratio May Be Vulnerable to Compression An Evidence-Based Framework for Understanding Silver’s Physical Market

Executive Summary On August 13, 2026, spot gold traded at approximately $4,403/oz** and spot silver at approximately **$65.42/oz, yielding a gold-silver ratio of roughly 67.3. Silver presents an unusual commodity-market paradox: a metal whose marginal supply is heavily dependent on other metals is simultaneously becoming more important to industrial manufacturing, while a growing share of historical silver is economically difficult to mobilize quickly.

One of the most revealing statistics in the current silver market is that, even after substantial demand destruction, thrifting, substitution and increased recycling, the market is still forecast to remain in deficit by 46.3 million ounces in 2026 — the sixth consecutive annual deficit.

This article examines the structural supply-demand imbalances that produce this outcome: constrained supply responsiveness, large industrial demand, persistent deficits, and a limited pool of readily mobilizable inventories. Rather than asserting a single “correct” ratio, we present a framework for understanding why the current ratio may be vulnerable to compression if physical tightness persists.

The bottom line: the physical supply-demand picture suggests the current gold-silver ratio may be vulnerable to compression if current trends persist.

The Core Framework Silver is different from gold in three economically important ways.

Its marginal supply is unusually constrained.

A large share is produced as a byproduct, so higher silver prices don’t automatically generate proportional new supply. According to the Silver Institute’s World Silver Survey 2026, only about 26–28% of the silver mined globally each year comes from primary silver mines — operations that specifically target silver. The remainder comes from operations where silver is a byproduct or coproduct of other metals, including lead-zinc, copper, and gold.

Its marginal demand is increasingly industrial.

Solar, electrification, electronics, automotive and other applications create demand that isn’t purely investment-driven. According to the Silver Institute, industrial demand accounted for roughly 58% of total silver demand in 2025.

Its existing stock is less economically liquid.

Above-ground silver is not homogeneous. Monetary and investment stocks can respond relatively quickly to price signals, whereas silver dispersed in low-concentration industrial applications may be technically recoverable but economically unavailable at prevailing prices.

That combination creates the possibility of a nonlinear supply response when investment demand and industrial demand compete for the same relatively small pool of readily mobilizable metal.

Part I: The Supply Picture The Mining Ratio: A Supply Constraint Global mine production has historically produced roughly 7–11 ounces of silver for every ounce of gold. The mining ratio therefore establishes a constraint on the composition of marginal supply, not a valuation target for the metals. The gold-silver ratio is not determined by geology alone, but physical-market conditions can influence the relative scarcity, liquidity and marginal pricing of the two metals.

The Consumption Factor: A Divergence in Economic Availability Here’s where the supply picture diverges dramatically from gold.

Factor Gold Silver Total Ever Mined ~219,891 tonnes ~1.6-1.74 million tonnes Still Recoverable ~90%+ Substantial proportion believed lost or economically unrecoverable Recycling Relative to Mine Production ~38% (2025) ~25% (2026 forecast) Industrial Consumption Minimal ~58% of total demand Gold is accumulated and almost never destroyed. Approximately 90%+ of all gold ever mined still exists in recoverable form. It can be melted and reused indefinitely.

Silver is rarely destroyed at the atomic level when used industrially. The economic issue is that much of it becomes dispersed into products, residues and applications from which recovery is technically possible but uneconomic at prevailing prices. The Silver Institute has published analysis suggesting that a very large proportion of historical silver production has become lost or practically irrecoverable, but the estimates have a broad plausible range and depend heavily on assumptions.

The Six-Year Deficit: 762 Million Ounces The Silver Institute projects a sixth consecutive annual market deficit in 2026. The World Silver Survey 2026, published by the Silver Institute and Metals Focus on April 15, 2026, puts this year’s deficit at 46.3 million ounces — up 15% from 40.3 million ounces in 2025. Total silver demand is forecast to fall roughly 2% to approximately 1.11 billion ounces in 2026. Mine production is forecast at 844.1 million ounces and recycling at 211.3 million ounces.

This figure is a cumulative market-balance statistic, not a measurement of physical inventory depletion. Including the Silver Institute’s 2026 forecast, cumulative market deficits from 2021 through 2026 amount to roughly 762 million ounces — approximately nine-tenths of a year’s forecast global mine production.

The ETP Balancing Mechanism

The headline market deficit should not be interpreted as a direct measure of physical depletion. Investment flows are an important balancing mechanism: the 2026 World Silver Survey estimates that the market balance excluding net ETP investment would be a larger 76.3 million ounces in 2026, compared with the headline deficit of 46.3 million ounces.

The relevant question, therefore, is not simply how many ounces the market has been “short” on paper, but how much readily mobilizable above-ground inventory remains available to absorb future deficits.

As the Silver Institute’s World Silver Survey 2026 confirms, falling inventories, a dramatic shift of metal into CME vaults, rising exchange-traded product holdings, and a surge in bar and coin demand have created what the Survey describes as an “era of reduced stocks” with thinner liquidity, greater lease-rate volatility and potentially larger price moves.

The Visible Supply: What’s Actually Available One of the most transparent measures of reported physical silver inventories is exchange-vault inventory.

As of end-June 2026, LBMA vaults held 9,464 tonnes of gold (a 0.77% increase on the previous month) valued at $1.2 trillion, and 28,082 tonnes of silver (a 1.7% increase on the previous month) valued at $53.1 billion.

Aggregated exchange-vault figures provide a useful visibility measure, but they should not be interpreted as a pool of globally fungible silver available for immediate sale. Reported exchange-vault inventories across COMEX, LBMA, SHFE, and SGE totaled approximately 1.30 billion troy ounces of silver and 332.6 million troy ounces of gold as of July 30, 2026, according to MetalCharts.

Exchange Gold Silver Ratio (Ag:Au) COMEX 23.0M oz 332.2M oz ~14.4:1 LBMA 304.3M oz 902.8M oz ~3:1 Total Reported 332.6M oz 1.30B oz ~3.9:1 COMEX silver inventory data as of August 11, 2026:

Category Ounces Registered (deliverable) 99,321,657 oz Eligible 236,110,488 oz Total 335,432,145 oz These figures provide a transparent snapshot of exchange-reported inventories, not a complete measure of global above-ground silver. They represent metal sitting in reported exchange inventories today. Those inventories have declined in several major venues during periods when the broader market has also recorded persistent deficits, although the deficit figures do not by themselves establish that each inventory decline was caused directly by the cumulative deficit. Historically reduced and unevenly distributed readily mobilizable inventories remain a key feature of the market despite fluctuations in reported vault stocks.

Part II: The Demand Picture Industrial Demand: The Structural Shift Industrial demand accounted for roughly 58% of total global silver demand in 2025, according to the Metals Focus/Silver Institute demand classification. The Silver Institute’s 2025 survey reported record 2024 industrial demand of 680.5 million ounces. In 2025, industrial fabrication declined by 3% to 657.4 million ounces, driven primarily by weakness in photovoltaics and electronics.

The 2026 forecast shows industrial fabrication falling another 3% to 639.6 million ounces — a four-year low — as photovoltaic demand continues to slow. Total silver demand is projected to ease another 2% to 1.11 billion ounces in 2026.

Where does the remaining demand go?

Sector 2025 Actual 2026 Forecast Photovoltaic (solar) 186.6 Moz 151.0 Moz (−19%) Electrical & electronics Declined 2% Continued structural growth in AI infrastructure Automotive Strong end-use Healthy Power grid investment Healthy Healthy A Critical Nuance: Solar Thrifting

The photovoltaic sector’s silver demand is forecast to fall 19% in 2026 — the largest single-year reduction on record — as intense competition and rising silver raw material costs prompted PV manufacturers to accelerate thrifting (using less silver per cell) and substitution. This does not mean solar deployment is falling — it means manufacturers are responding to high silver prices by reducing silver loadings per unit.

The 2026 Silver Institute forecast shows total silver demand falling 2% while the deficit is widening, because supply is contracting faster than demand. Both sides of the ledger are shrinking; the gap is growing.

Government Recognition: The USGS Critical Minerals Designation In November 2025, the U.S. Geological Survey published its final 2025 List of Critical Minerals, revising the 2022 list and outlining 60 minerals vital to the U.S. economy and national security.

Silver was added for the first time. The final list added 10 new minerals — boron, copper, lead, metallurgical coal, phosphate, potash, rhenium, silicon, silver, and uranium — based on new data, public feedback and interagency recommendations.

Gold was not included.

Silver’s inclusion reflects the USGS assessment that its economic importance and supply-chain vulnerability meet the statutory criteria for critical-mineral designation. Under the Energy Act of 2020, a mineral qualifies as “critical” only if it is essential to U.S. economic or national security, has a supply chain vulnerable to disruption, and serves an essential manufacturing function. USGS specifically lists silver’s uses in electrical circuits, batteries, solar cells, and antibacterial medical instruments.

The Defense Demand Gap: A Documented Reporting Gap The Silver Institute’s World Silver Survey breaks demand into categories like solar, electronics, jewelry, and brazing alloys. Defense and aerospace do not appear anywhere in it as a standalone category.

Publicly available U.S. government data on silver use became substantially less detailed after the dissolution of the Bureau of Mines in 1996, and modern defense-specific silver consumption is difficult to isolate from broader industrial categories. The National Defense Stockpile’s silver holdings fell from nearly 4,300 metric tons in 1982 to approximately 1,700 tonnes by late 1994, and were ultimately depleted by 2002.

The reporting gap makes current defense-related silver consumption unusually difficult to quantify, particularly given silver’s documented importance in military electronics and batteries.

Known Military Applications

Despite the classification, we know silver remains an important material in a range of modern military systems. Silver-zinc batteries power guidance, telemetry, and actuation systems across Tomahawk, Patriot, THAAD, Hellfire, and Standard Missile programs. Silver-plated connectors, wiring harnesses, and circuit boards run throughout military avionics under mil-spec requirements.

A Necessary Correction to the Bull Case

One widely cited figure — 480–500 ounces of silver per Tomahawk — appears frequently in silver analysis. Secondary reporting citing CPM Group places the actual figure at closer to 10–15 oz per Tomahawk, primarily in solder and an ignition battery. Smaller missiles used in conflict zones reportedly carry less than 1 oz each.

This is an important correction. Overstating per-unit silver loadings undermines the credibility of the underlying demand case, which is real even at accurate numbers.

The Estimated Scale

According to CPM Group’s Jeffrey Christian, globally, between 10–20 million ounces of silver are used each year for warfare-related purposes such as missiles and electronics, mostly in the U.S. This is an inference rather than a published government or industry total, and the range is wide because the data is structurally thin.

Importantly, the silver thesis does not depend on proving a large hidden defense demand component. The published supply-demand balance is already tight; defense demand is best viewed as a potential additional source of uncertainty rather than a required pillar of the thesis.

The Manhattan Project Precedent

The most dramatic historical precedent is the Manhattan Project. In complete secrecy, the United States removed approximately 395 million ounces of silver (13,540 short tons) from the West Point Bullion Depository to turn 1,000-ounce silver bars into cylindrical billets for magnetic coils in uranium enrichment. The silver was eventually returned by 1970, but the precedent is clear: classified military projects can consume industrial quantities of silver without any public record.

The Manhattan Project demonstrates that strategically important U.S. programs have historically been capable of mobilizing hundreds of millions of ounces of silver outside ordinary commercial-market channels. It does not provide evidence that comparable quantities are being consumed by classified programs today.

Part III: Supply Shocks and Catalysts The Sulfuric Acid Export Restrictions: A Potential Host-Metal Supply Constraint On May 1, 2026, China imposed new restrictions on sulfuric-acid exports. The restrictions apply to smelter and sulfur burner-based acid with the sole exception of electronic-grade material. The restrictions are tentatively expected to last through December 31, 2026.

This doesn’t sound like a silver story. It is.

Sulfuric acid is the lifeblood of copper mining — specifically the heap leach process that extracts copper from lower-grade oxide ores. China, the world’s largest sulfuric acid exporter, shipped approximately 4.6 million metric tonnes in 2025. Chile — the world’s largest copper producer — was China’s largest foreign acid market in 2025, with China supplying 37.1% of Chile’s sulfuric acid imports. Chile imported 4 million metric tonnes of sulfuric acid in 2025.

By March 2026, Chinese sulfuric-acid exports to Chile had fallen to zero (compared with 31,870 tonnes in February and 151,268 tonnes in March 2025). S&P Global analysts noted that “a long-lasting ban could impact copper cathode production in Chile.”

A large majority of newly mined silver is produced as a byproduct or coproduct of other metals, including lead-zinc, copper and gold. Consequently, a higher silver price does not automatically induce a proportional increase in mine supply.

This is a potential second-order silver supply risk, not a quantified silver-supply shock. The relevant constraint is not that copper disruptions remove silver one-for-one, but that a significant portion of silver’s supply is governed by the economics of other metals. The effect on silver depends on which mines reduce output, their silver grades, and whether other mines or recycling offset the lost production.

The Diesel Shortage: Energy Costs Rising The Iran conflict has severely disrupted commercial traffic through the Strait of Hormuz since February 28, 2026. On August 12, 2026, Kpler data showed only eight vessels transiting the strait, the lowest daily count since August 5, compared with a pre-war norm of roughly 130 to 140 ships.

The disruption creates the potential for higher diesel and freight costs for energy-intensive mining operations across multiple regions. The combination of constrained Chinese acid exports and Middle Eastern energy disruption could create a compound cost and supply risk for energy-intensive mining and processing operations.

Part IV: Market Structure and Paper Leverage Gross Financial Exposure Relative to Physical Inventory Analyst Faysal Amin estimates gross financial exposure to silver at approximately 356 times the physical-inventory denominator used in his methodology. This is not equivalent to 356 contractual claims on every physical ounce. Derivatives net against one another, and most futures positions are closed or rolled rather than settled through physical delivery.

This metric is not universally standardized — what constitutes “paper,” what constitutes “physical,” whether ETFs are included, and what inventory denominator is used all affect the number. The ratio should be interpreted as a measure of gross financial exposure relative to a physical-inventory denominator, not as a literal count of delivery claims against each ounce.

Registered Inventory Relative to Gross Open Interest COMEX inventories should be separated into registered and eligible categories. Registered silver is immediately available for delivery against futures warrants, whereas eligible silver meets exchange specifications but is not necessarily committed to delivery.

As of August 11, 2026:

Metric Value Registered (deliverable) 99,321,657 oz Total COMEX Silver 335,432,145 oz Open Interest ~576M oz Registered inventory represented approximately 17% of the silver-equivalent ounces represented by gross open interest. This is not a futures delivery-coverage ratio — most futures positions are closed or rolled rather than taken to physical delivery. It is nevertheless a useful indicator of the relatively small pool of exchange-registered metal immediately available for delivery relative to the gross financial exposure represented by outstanding futures positions.

The January 2026 Delivery Run In early 2026, COMEX experienced a period of unusually large physical movements. Market commentary reported approximately 33.45 million ounces of COMEX silver being delivered or withdrawn during the early-January delivery period — roughly 26% of COMEX’s entire registered inventory at that time.

Large withdrawals can indicate multiple conditions: tightness in the physical market, arbitrage opportunities, inventory repositioning, or expectations of future delivery requirements. However, the withdrawals were a powerful signal of heightened demand for immediately deliverable metal and increased concern about available inventories.

Part V: A Hypothetical Delivery-Stress Scenario If physical tightness became sufficiently severe, one possible — but not inevitable — sequence would be as follows.

Stage 1: Physical Tightness

Wholesale premiums rise

Lease rates / financing conditions tighten

Registered inventory declines

Delivery demand increases

Stage 2: Futures-Market Response

Volatility increases

Margins rise

Spreads dislocate

Shorts seek physical metal or offset positions

Stage 3: Exchange Intervention

Position limits or other emergency measures may be adjusted

Trading may be temporarily restricted under exchange rules

Margin requirements can rise significantly

Stage 4: Potential Bifurcation

If physical premiums become sufficiently large, physical transactions can begin to diverge from futures benchmarks. In an extreme disruption, exchange rules provide mechanisms for extraordinary action, the precise form of which would depend on the circumstances and applicable rules.

Part VI: Valuation Scenarios Rather than asserting a single “correct” ratio, let’s examine illustrative price outcomes at progressively tighter gold-silver ratios.

Illustrative GSR Implied Silver Price (at ~$4,403/oz Gold) Current ~67.3:1 ~$65/oz 20:1 ~$220/oz 10:1 ~$440/oz 5:1 ~$881/oz 4:1 ~$1,101/oz 3:1 ~$1,468/oz 2:1 ~$2,202/oz Note: These scenarios hold gold constant at current prices; in an actual monetary or commodity shock, gold and silver would likely move simultaneously, so the table isolates the effect of ratio compression rather than forecasting an actual silver price.

These are sensitivity scenarios, not equilibrium estimates. They demonstrate what silver would be worth at a given gold price if the ratio compressed to each level.

The evidence supports the possibility that the current ratio understates the degree of physical tightness embedded in silver’s market relative to gold, but it does not establish a unique fair-value ratio.

Part VII: The Counterweight — Demand Destruction The principal counterweight to the scarcity thesis is price elasticity. Silver is not an inelastic commodity on the demand side.

High prices are already producing measurable thrifting and substitution in photovoltaics, while jewelry and silverware demand are forecast to decline sharply. The 2026 World Silver Survey forecasts:

PV silver demand falling 19%

Industrial demand falling 3%

Total demand falling 2%

Jewelry fabrication falling to a five-year low

Silverware demand falling to a four-year low

A sustained price increase can therefore release additional recycling while destroying marginal industrial demand. The bullish case depends not on demand being perfectly inelastic, but on the possibility that supply and readily mobilizable inventories become constrained faster than substitution, recycling and demand destruction can compensate.

This is arguably the most compelling quantitative fact in the entire article: even after substantial demand destruction, thrifting, substitution and increased recycling, the market is still forecast to remain in a 46.3 million ounce deficit.

Part VIII: The Core Thesis The gold-silver ratio is not determined by geology alone, but physical-market conditions can influence the relative scarcity, liquidity and marginal pricing of the two metals. Silver’s unusually low share of primary mine supply, high industrial dependence, persistent deficits, and historically reduced and unevenly distributed readily mobilizable inventories create conditions under which a historically high gold-silver ratio could become vulnerable to compression.

The strongest version of the silver thesis is not that a particular gold-silver ratio is “correct,” nor that a physical shortage guarantees an extreme price. It is that silver may be entering a regime in which marginal supply is unusually difficult to expand, readily mobilizable inventories are unevenly distributed, and industrial demand remains large enough that even substantial price-induced demand destruction may not immediately restore balance.

If that condition persists, the market’s clearing mechanism is likely to be some combination of higher prices, increased recycling, substitution, demand destruction and inventory mobilization. In that environment, a 67:1 gold-silver ratio could compress materially without requiring silver to reach any predetermined “fair-value” ratio.

The strongest argument for silver isn’t a mathematical claim that a specific ratio is “correct.” Rather, it’s a supply-demand imbalance thesis organized around three levels of certainty:

Tier 1 — Documented Facts

Silver’s market structure is unusual: only about 26–28% of mine production comes from primary silver mines

Industrial demand accounted for roughly 58% of total demand in 2025

2021–2025 recorded market deficits occurred; 2026 is forecast to be another deficit year

Silver is now on the U.S. critical-minerals list

Recycling is much smaller relative to historical above-ground stock than in gold

PV manufacturers are actively thrifting/substituting silver

Exchange inventories are not equivalent to total global inventory

The Manhattan Project really did temporarily commandeer ~395 Moz of silver

Tier 2 — Reasonable Market Inferences

Persistent deficits can reduce readily mobilizable inventories

Byproduct dependence can make silver supply less responsive than a conventional primary commodity

Host-metal disruptions can affect silver supply

Industrial silver stocks may be less economically liquid than monetary stocks

High prices can generate increasingly nonlinear physical-market responses

Tier 3 — Scenario-Dependent Hypotheses

Hidden defense demand is materially undercounted

Current classified programs consume large quantities of silver

A COMEX delivery crisis could cause a systemic paper/physical bifurcation

Silver could reach $500/$1,000+

A 3:1 or 2:1 gold/silver ratio represents a fundamental equilibrium

The current 67:1 ratio is definitively “mispriced”

Conclusion The silver market presents a rare convergence of:

Constrained supply (byproduct production, declining ore grades, potential sulfuric acid-related host-metal constraints)

Large and structurally important industrial demand, even as high prices are already producing measurable thrifting and substitution

Historically reduced and unevenly distributed readily mobilizable inventories (five consecutive historical deficits, followed by a sixth forecast deficit in 2026; cumulatively, the six-year sequence amounts to roughly 762 Moz)

Supply shocks (sulfuric acid restrictions, energy costs, geopolitical disruptions)

Paper leverage (the derivatives market is large relative to immediately deliverable exchange inventory, though commonly cited paper-to-physical ratios are methodology-dependent and should not be interpreted as literal claims on each ounce of silver)

Potentially undercounted defense demand, while difficult to quantify, represents an additional uncertainty rather than a necessary component of the thesis

This doesn’t mean silver must reach $1,000+ per ounce. Commodity markets are complex, and prices are influenced by sentiment, macroeconomics, and monetary policy. Physical shortages can be alleviated by demand destruction or increased recycling.

However, the structural imbalance in the silver market is significant. The available physical-market evidence — constrained supply responsiveness, large industrial demand, persistent deficits, and historically reduced and unevenly distributed inventories — suggests the gold-silver ratio may be vulnerable to compression.

The current ratio of roughly 67:1 may be vulnerable to compression if persistent physical-market tightness continues.
