Platinum and palladium

The platinum group metals at a glance

The platinum group metals, or PGM, are six chemically related elements: platinum (Pt), palladium (Pd), rhodium (Rh), ruthenium (Ru), iridium (Ir) and osmium (Os). For an investor the list is effectively two items long. Only platinum and palladium are struck into bullion coins, poured into investment bars and wrapped into exchange-traded products in any quantity.

Rhodium is worth a footnote and no more. It is the third metal in a three-way catalyst, its supply is even more concentrated in South Africa than platinum's, and the combination has produced some of the most extreme price swings ever recorded in a traded metal. But there is no meaningful coin market, spreads on the few products that exist are very wide, and no liquid public reference auction underpins it. Ruthenium, iridium and osmium are smaller still and are industrial materials rather than investable assets.

What sets platinum and palladium apart from gold is not rarity — both are scarcer in the ground — but purpose. Gold is bought to be kept. These two are bought to be used up: coated onto ceramic honeycombs, dissolved into chemical processes, drawn into electrical contacts. Investment demand sits on top of an industrial market rather than defining it. That makes the price cyclical rather than counter-cyclical, and means a recession can push it down at exactly the moment a gold investor would expect a precious metal to rise. Live quotes are on the platinum price page and the palladium price page, the long series on the historical prices page.

How platinum and palladium are quoted

Both are quoted internationally in US dollars per troy ounce of 31.1035 grams, exactly as gold and silver are. Anyone outside the dollar area therefore holds two exposures at once: the metal and the exchange rate, and over multi-year periods the currency contribution is far from trivial. Current rates are on the exchange rates page.

The official reference figures are the LBMA Platinum Price and the LBMA Palladium Price, each established twice on every trading day in an electronic auction, at 09:45 and 14:00 London time, in dollars per ounce. Historically this sat with the London Platinum and Palladium Market (LPPM), whose name still attaches to the good delivery standards for PGM bars and sponge. Since 1 July 2026 the auctions have been administered by ICE Benchmark Administration, which took over from the London Metal Exchange and already runs the equivalent LBMA fixings for gold and silver.

Alongside the auctions runs the continuous over-the-counter spot price, plus platinum and palladium futures on the exchanges. Arbitrage keeps all of these tied closely together, as in gold. The difference is depth: the PGM market is far thinner, so a single large order can move the quote in a way that would barely register in gold.

Demand: catalytic converters and industry

By some distance the largest single use of both metals is the catalytic converter in road vehicles, where PGM coated onto the converter substrate turn carbon monoxide, unburnt hydrocarbons and nitrogen oxides into less harmful compounds. No practical substitute for the platinum group exists in that role, which is why emissions legislation, rather than any investment fashion, has been the dominant force in these markets for four decades.

There is a rough division of labour between the two, driven by chemistry and by which engine the converter is fitted to:

Palladium is the more exposed. The overwhelming share of its demand comes from petrol vehicle exhaust systems, which makes the price close to a leveraged bet on global light vehicle production and on the tightness of emissions limits. Platinum is better spread: diesel after-treatment remains important, but jewellery, chemical process catalysts, glass fibre bushings, electronics and medical implants all draw on it.

Neither metal has anything resembling gold's official sector demand — central banks do not hold PGM as reserves. That removes a large, price-insensitive, steady buyer from the picture, and is one reason the two behave more like industrial commodities than monetary metals.

Substitution between the two metals

Because platinum and palladium are chemically similar, they can partly stand in for one another in an exhaust catalyst. This is not a laboratory theory but a routine commercial decision: when one metal becomes persistently more expensive, engineers reformulate the washcoat to use more of the cheaper one, and the change works its way into new vehicle platforms over a few years.

The mechanism has been observed in both directions. Through the years when palladium traded well above platinum, manufacturers substituted platinum back into petrol catalysts on a meaningful scale. Earlier, when platinum was the expensive metal, the substitution ran the other way.

Two consequences follow. First, extreme valuation gaps between the two tend to close eventually, because the price difference itself creates the demand shift that narrows it — substitution acts as a built-in negative feedback loop. Second, the adjustment is slow. Reformulating a catalyst requires re-engineering and re-certification, so the response is measured in years, not weeks, and a gap can stay wide for a long time before anything happens. Substitution is a long-run anchor, not a short-run trading rule.

Hydrogen as a structural driver for platinum

One demand story applies to platinum alone. In proton-exchange-membrane electrolysers, which split water to make hydrogen, and in the fuel cells that turn hydrogen back into electricity for trucks, buses and stationary generators, platinum serves as the catalyst. Built at scale, that would add a block of platinum demand with nothing to do with combustion engines.

The honest framing is that this is a scenario, not a fact. How much platinum it eventually absorbs depends on how quickly electrolyser and fuel cell capacity is actually installed, and on how far manufacturers can cut the platinum loading per cell — an active engineering effort, since the metal is one of the more expensive components. Both variables are genuinely open, and published projections vary widely.

What can be said without speculating is that the exposure is asymmetric. Platinum has a plausible non-automotive growth channel that could partly offset the decline of the diesel catalyst. Palladium does not: the same shift towards zero-emission drivetrains that might create platinum demand simply removes palladium demand.

Supply: extreme country concentration

The supply side is geographically concentrated to a degree matched by almost no other traded commodity. Roughly 70 per cent of mined platinum comes from South Africa, overwhelmingly from the Bushveld Complex. For palladium, Russia and South Africa each supply something like 40 per cent, with Russian output dominated by a single company operating in the Arctic. Zimbabwe, Canada and the United States account for most of the remainder.

Concentration of that kind creates a specific fragility. A strike in the South African platinum belt, a power rationing programme by the national electricity utility, a shaft accident or a change in the sanctions regime affecting Russian metal can each remove a visible slice of world supply within days. Disruptions of exactly these types have repeatedly produced sharp price moves in both metals.

Compounding this, PGM are usually extracted through by-product mining — as a co-product of nickel and copper operations, or from deep reef mines whose economics depend on a basket of metals rather than any single one. Output therefore responds sluggishly to price: a high palladium price cannot conjure extra palladium out of a nickel mine whose schedule is set by nickel, and a new shaft takes years and a great deal of capital. Inelastic supply meeting cyclical demand is a recipe for violent prices. National production data are compiled by the USGS.

Recycling from spent catalytic converters

Secondary supply matters more here than in most metal markets. Spent autocatalysts are collected when vehicles are scrapped, the ceramic monolith is crushed and smelted, and the platinum, palladium and rhodium are recovered at high yield. Together with process residues from the chemical and electronics industries, this precious metal recycling stream supplies a substantial share of the metal reaching the market each year.

Recycling behaves quite differently from mining. It is genuinely price-responsive: when quotes are high, collection rates rise, scrapyards pay more for converters, and material that would otherwise sit in a shed comes forward. It also follows the vehicle scrappage cycle, so a period of low new-car sales shows up as weaker recycled supply several years later, when fewer vehicles reach the end of their lives.

There is a less pleasant corollary: high PGM prices have made catalytic converter theft a recurring problem in several countries. Because these metals are dispersed through the physical economy in tiny, valuable quantities, secondary flow is shaped by economics on the ground rather than by mine planning departments.

A thin market and wide spreads

Both markets are small. Measured by annual value, platinum and palladium together are a modest fraction of the gold market, and the free-floating investment portion is smaller still. That has consequences a private buyer feels directly.

The spread between what you pay and what you would receive on the way back is wider than for gold. So is the premium over metal value on coins and small bars, because fabrication and distribution costs are spread over fewer units and inventory risk is higher in a market that can gap. Combined with VAT in jurisdictions that charge it, the round trip on physical platinum or palladium starts a long way underwater.

The honest way to look at that is to separate metal value from everything else. The melt value calculator isolates the pure metal content of an item, and the purchase price calculator estimates what a sale below spot realistically returns; the gap between those two numbers is the true cost of ownership.

Volatility and the electric vehicle risk

Platinum and palladium show far higher volatility than gold, and palladium is routinely among the most volatile precious metals of all. Three factors compound each other: the small market size, so modest order flow moves the price a long way; the direct dependence on the industrial cycle, which adds recession risk gold does not carry; and the inelastic, concentrated supply, which turns any disruption into a squeeze. Investors who reach for these metals expecting the defensive behaviour of a safe haven are usually disappointed, and the historical record does not support that role for either.

On top of cyclical swings sits a structural question. Battery-electric vehicles have no combustion engine and therefore no exhaust catalyst at all. To the extent they displace petrol and diesel vehicles, the largest demand block for both metals shrinks permanently rather than cyclically. The exposure is most acute for palladium, which has little else to fall back on; platinum is partly cushioned by its industrial breadth and by hydrogen.

How fast this plays out is disputed, and depends on regulation, charging infrastructure, battery costs and regional policy in ways nobody can pin down; hybrids, which do have catalysts, complicate the arithmetic further. What can be stated plainly is the direction of the risk and that it is structural rather than temporary. It is not a prediction about the price.

Ways to invest: coins, bars and ETCs

Physical platinum and palladium exist in the same formats as gold. Bars are produced in standard weights by the major refiners, and several national mints issue platinum or palladium versions of familiar bullion coins — among them the Canadian Maple Leaf, the American Eagle and Buffalo, the Austrian Philharmonic and the British Britannia. The choice is narrower than for gold and silver, production runs are smaller, and some issues appear only in certain years.

Away from metal, physically backed exchange-traded commodities track the spot price through the stock exchange. They avoid storage, insurance and, in most jurisdictions, the VAT charge on physical metal, which is a genuine advantage. The trade-off is legal form: an ETC is a debt security, so the holder carries issuer risk on top of price risk, even where the structure is collateralised with allocated metal. That is a different risk profile from a coin in a drawer, not a smaller one.

Either way, the small size of the underlying market shapes the experience. Flows that the gold market would absorb invisibly can move these prices noticeably, and liquidity can thin out precisely when a holder most wants to trade.

VAT: no investment gold privilege

This is the single most important practical difference from gold. The VAT exemption for precious metals — Articles 344 and following of the EU VAT Directive, implemented in Germany as § 25c UStG — applies only to investment gold. Platinum and palladium are ordinary goods for VAT purposes and are taxed at the standard rate.

In Germany that means 19 per cent VAT on the entire purchase price when buying platinum or palladium bars. No margin scheme is available for bars, and the former workaround of holding metal in a bonded warehouse to defer the charge was effectively closed off in 2025. Some collector coins may fall under the margin scheme, which changes the arithmetic, but the standard case for investment-grade bars is the full rate. The effect is structural, not cosmetic: the price has to rise by roughly the tax before a purchase breaks even on resale — a materially higher hurdle than gold faces.

On disposal the treatment is identical to gold and silver. In Germany a gain on privately held physical metal is a private disposal transaction under § 23 EStG: after a holding period of more than one year it is entirely tax-free, and within the year it is taxed at the personal income tax rate once the annual threshold of 1,000 euros is exceeded. Note that this is a threshold, not an allowance — exceed it and the whole gain becomes taxable.

These are German rules, cited because this international edition uses German law as its reference point. VAT rates and capital gains treatment differ considerably across Europe, and several countries tax precious metal gains with no holding period at all. The tax calculator applies the rules of the individual countries. None of this is tax advice.

The platinum-gold and palladium-platinum ratios

Two ratios help place these metals in context. The platinum-gold ratio divides the platinum price by the gold price. For much of modern history platinum traded above gold, reflecting its industrial demand and scarcer supply; for many years more recently it has traded below. A low reading says platinum is inexpensive relative to gold, and nothing more. Such ratios can sit at an apparent extreme for years, and nothing forces them back to a historical average.

The palladium-platinum ratio compares the two sister metals directly, and it is the more informative of the pair because a real economic mechanism sits behind it. When palladium trades well above platinum, the incentive to substitute platinum into petrol catalysts becomes commercially compelling, and that substitution eventually pulls the ratio back. The ratio is therefore a rough gauge of how much substitution pressure has built up.

The equivalent for the monetary metals is the gold-silver ratio, which works on a similar principle but without the substitution feedback. All of these are context, not forecasts.

Platinum or palladium?

Both are small, volatile, industrially driven niches, so the question is not which is better but which set of drivers you are exposed to. Palladium hangs almost entirely on the petrol catalyst and therefore carries the purest electric vehicle risk of any traded metal. Platinum is more broadly based — diesel after-treatment, jewellery, chemicals, glass, medical — and has in hydrogen a possible long-term driver that palladium lacks.

Against that, platinum carries its own concentration problem: a single country supplies most of it, and South African mining has a long record of strikes and power interruptions. Palladium's supply is split between two countries, but one of them is subject to sanctions risk that can change with a policy announcement.

Substitution links the two prices over the long run, so a portfolio holding both is less diversified than it looks. This guide makes no recommendation for either metal and no forecast. Both sit at the speculative end of the precious metals spectrum and are generally discussed as a small satellite position, if at all.

Authenticity and storage

Checking a bullion coin works as it does for gold and silver. Standard issues have defined specifications, so if diameter, thickness and weight match the published figures and the implied density is right, the great majority of fakes are already excluded. Platinum is denser than gold, about 21.4 grams per cubic centimetre against gold's 19.3; palladium is much lighter, around 12.0, which is why a palladium coin of a given ounce weight looks noticeably larger than its gold equivalent. The coin authenticity checker and the coin weight reference hold the target values.

Because platinum and palladium coins circulate in far smaller numbers, fewer people handle them regularly and reference specimens are harder to come by. Documentation matters correspondingly more: an assay card left intact, an invoice from a traceable channel and, for bars, an unbroken chain of custody all make resale easier. In a thin second-hand market, provenance is worth real money.

Storage poses no special problem. Both metals are dense, so the bulk issue that makes silver awkward does not arise, and the usual options apply. What needs planning is not storage but exit: fewer buyers, wider spreads and occasionally reluctant buy-backs mean selling is generally slower and more expensive than with gold.

What this market does and does not tell you

Platinum and palladium sit awkwardly between two categories. They have the physical characteristics of precious metals, yet their prices are set by industrial demand, emissions policy and the operating condition of a handful of mines. Treating them as small versions of gold produces the wrong expectations in both directions.

The things worth carrying away are structural rather than predictive. Supply is concentrated in two countries and cannot respond quickly to price. Demand is dominated by one application under long-term regulatory and technological pressure. The two substitute for each other, which links their prices over years while allowing wide gaps in between. The market is thin, so prices move hard on modest flow. And across the EU, VAT is charged on the purchase, which is the highest single hurdle a physical buyer has to clear.

For comparison, the gold price page and the silver price page cover the two larger markets, and the remaining terminology is collected in the glossary.
