Silver as an Investment: The Dual-Nature Precious Metal

Silver is one of the oldest forms of money and one of the most versatile industrial materials known. It combines the characteristics of a monetary metal — historically used as currency, often rallying during financial stress — with significant industrial demand that is growing as the energy transition requires more photovoltaic cells, electronics, and electrical contacts. This dual nature makes silver both more volatile and more complex to analyse than gold, and creates an investment case that rewards a deeper understanding of the fundamentals.

Silver's Two Identities

As a monetary metal, silver has been used as currency for thousands of years. The word "sterling" derives from silver coin standards; many currencies still bear etymological links to silver. Like gold, silver is held as a store of value, a hedge against currency debasement, and a safe-haven asset in periods of financial stress. Unlike gold, however, silver has a much larger industrial demand component, which means it responds to economic conditions as well as monetary conditions.

As an industrial metal, silver is uniquely valuable. It is the best electrical and thermal conductor of all metals. It has powerful antimicrobial properties used in medical devices, coatings, and textiles. And its use in photovoltaic (solar) cells has grown enormously as the world installs more solar capacity.

Solar Panels and the Industrial Demand Revolution

Solar is the most significant structural demand driver for silver over the coming decade. Each silicon solar cell requires a small amount of silver paste to conduct electricity — approximately 8 grams per panel on average, though new designs are moving to reduce this intensity. As global solar capacity continues to expand — the IEA forecasts solar additions of over 500 GW per annum by the late 2020s — the cumulative demand for silver in solar manufacturing is substantial.

The Silver Institute estimates that solar accounted for approximately 19% of global silver demand in 2024 (around 232 million ounces — roughly a third of all industrial silver use), up from around 5% a decade earlier. This shift has structurally changed the silver demand profile. Even if photovoltaic manufacturers succeed in reducing silver intensity per panel, the sheer volume of panels being installed can more than offset efficiency improvements in aggregate silver terms.

Silver is also used extensively in electronics (contacts, switches, conductive inks), electric vehicles (contactors, charging systems, sensors), 5G infrastructure, and medical equipment. The collapse in photographic demand (silver halide film) from the late 1990s onwards has been more than offset by new industrial applications.

The Gold-Silver Ratio

The gold-silver ratio — the number of troy ounces of silver required to purchase one troy ounce of gold — is one of the most widely followed indicators in precious metals markets. Historically, the ratio has averaged approximately 55–65:1 over long periods, with significant cyclical swings.

The ratio reached 125:1 in March 2020, during the peak of pandemic-driven financial stress — an extreme reading that suggested silver was historically cheap relative to gold. It subsequently fell sharply as silver recovered. In 2026 the ratio has generally ranged between roughly 55:1 and 65:1.

Investors use the ratio in two ways: as a valuation signal (a high ratio suggests silver may outperform gold in the next cycle), and as a tactical switching indicator (sell gold/buy silver when the ratio is high, and reverse when it normalises). This approach has historical merit but requires patience — the ratio can remain elevated or depressed for years.

Investment Routes

Physical Silver (Coins and Bars)

Physical ownership of silver coins or bars provides the most direct exposure. However, silver's lower price per ounce relative to gold means that the same nominal value requires a much larger physical volume and weight — a £100,000 position in silver requires over 60 kg of metal (at approximately £25/troy oz). Storage and insurance costs per £ invested are therefore much higher than for gold.

UK investors should note that investment silver (coins and bars) attracts VAT at 20%, unlike investment gold which is VAT-exempt. This makes physical silver an expensive way to hold the metal for investment purposes unless held offshore in a VAT-exempt location.

Exchange-Traded Products (ETPs)

iShares Physical Silver ETC (SSLN — London-listed): one of the most liquid silver ETCs available to UK investors, holding physical silver allocated in HSBC vaults. This is the most common route for institutional and sophisticated individual investors.

Sprott Physical Silver Trust (PSLV — Toronto-listed): a closed-ended vehicle holding physical silver, with the option to redeem shares for physical delivery. Accessible through international brokerage accounts.

WisdomTree Physical Silver (PHAG — London-listed): similar to the iShares product, with allocated silver backing. Competitive management fee.

ETPs holding physical silver do not incur VAT, as the purchase is of a security, not metal directly. The silver is held in a custodian vault, and the investor owns a proportionate claim.

Sprott Physical Silver Trust vs ETCs

The key structural difference is that the Sprott vehicle is a closed-ended fund, meaning it can trade at a premium or discount to the value of the underlying silver. During periods of high retail demand (the "WallStreetBets silver squeeze" in February 2021, for example), the trust can trade at significant premiums to spot. ETCs, by contrast, have creation/redemption mechanisms that keep prices very close to the silver spot price.

HMRC Tax Treatment

CGT — important distinction from gold. Investment gold (coins produced by HMRC-approved mints, certain bars) qualifies for CGT exemption under the wasting asset rules. Silver does NOT qualify for this exemption. Silver coins and bars are chattel assets subject to the standard CGT rules.

Gains on silver ETCs or physical silver are taxable as capital gains in the hands of UK residents, with the standard annual exemption and rates (18%/24% for basic/higher rate taxpayers as at 2026, depending on the asset). There is no VAT on the disposal of silver ETCs.

Non-UK residents should review the treatment in their country of residence. Most jurisdictions treat precious metal ETC gains as capital gains.

Silver Miners

Silver miners offer leveraged equity exposure to the silver price. Major publicly listed silver miners include:

Fresnillo (FRES — FTSE 100, London-listed): one of the world's largest silver producers, operating primarily in Mexico. Fresnillo is an accessible, FTSE 100 route to silver mining exposure with a long operating history.

First Majestic Silver (AG — NYSE/TSX): a pure-play primary silver miner with operations in Mexico and Nevada. Higher risk, higher leverage to the silver price.

Pan American Silver (PAAS — NYSE/TSX): diversified silver and gold producer with operations across the Americas.

Silver miners tend to exhibit beta of 1.5–2.5x the silver price over the course of a cycle — they outperform in silver bull markets and underperform in downturns. Operational, political (most are in Latin America), and management risks add to commodity price risk.

Silver vs Gold in a Portfolio

Silver and gold are highly correlated over long periods (correlation approximately 0.8–0.85 over rolling 5-year periods) but diverge significantly during cycles. Silver tends to outperform gold in commodity upswings and underperform in risk-off episodes. This means silver provides more cyclical sensitivity — it amplifies the monetary metal exposure rather than purely providing the safe-haven function of gold.

A common portfolio approach is to hold gold as the primary monetary metal position and use a smaller silver allocation (half the size or less) for leveraged upside in a precious metals bull market.

Risks

Higher volatility than gold. Silver price swings of 30–50% within a year are not unusual. Investors must have the time horizon and risk tolerance to absorb this.

Industrial demand cyclicality. An economic slowdown that reduces manufacturing, electronics, and solar installation activity will reduce industrial silver demand.

VAT on physical silver. UK-domiciled investors holding physical silver pay 20% VAT, reducing effective returns.

Mining company risks. Latin American political risk, permitting difficulties, and operational hazards apply to all silver miners.

The value of investments can fall as well as rise. Tax rules change and the treatment described here reflects the position as understood in 2026. Seek professional tax advice before investing.
