Platinum
Also: Pt, white gold (historical)
Platinum is a rare, silvery-white precious metal of the platinum group with atomic number 78 that, thanks to its exceptional corrosion resistance, catalytic properties and industrial versatility, ranks among the most valuable metals on earth.
Platinum has fascinated humankind for centuries through its unusual blend of extreme chemical resilience, high density and technical versatility. The silvery-white metal belongs to the platinum group metals and is a close relative of palladium, rhodium, iridium, ruthenium and osmium. Its current platinum price is set by a global futures market driven heavily by industrial demand and mine output – a pattern that distinguishes platinum fundamentally from gold.
Origin and history
The name derives from the Spanish "platina", a diminutive of "plata" (silver), meaning roughly "little silver". Spanish conquistadors came across the metal in Colombia in the 16th century, initially took it for inferior, immature silver, and in places even discarded it into the sea. Only in the 18th century did European chemists and metallurgists recognise the element's independent character. Today platinum ranks among the rarest and economically most significant metals of all.
Occurrence and mining
Platinum is extraordinarily rare in the Earth's crust – its average concentration is about 0.005 ppm (parts per million). Annual world production stands at around 180–200 tonnes, compared with roughly 3,300 tonnes for gold.
Mining is heavily concentrated geographically:
| Region | Share of world production (approx.) |
|---|---|
| South Africa (Bushveld Complex) | ~70 % |
| Russia (Norilsk Nickel) | ~12 % |
| Zimbabwe | ~8 % |
| North America + other | ~10 % |
The South African Bushveld Igneous Complex is the largest known platinum deposit in the world. There, platinum is recovered mainly as a by-product of nickel and copper mining, which sharply delays the supply response to price changes and sets the market structure apart from other precious metals.
Chemical and physical properties
Platinum is one of the heaviest elements: with a density of 21.45 g/cm³ it clearly exceeds even gold (19.32 g/cm³). Its key properties at a glance:
- Corrosion resistance: platinum does not dissolve in ordinary acids. Only aqua regia (a mixture of concentrated hydrochloric and nitric acid) attacks it.
- Catalytic activity: the surface of platinum metal accelerates numerous chemical reactions without being consumed itself – the basis of its most important field of use.
- Ductility: platinum can be drawn into extremely fine wires and rolled into foils.
- Biocompatibility: it is largely inert to the human body and therefore suitable for medical implants and chemotherapeutic agents.

Industrial use
Around 75–80 % of global platinum demand goes to industrial applications – which sets the metal apart fundamentally from gold, where investment and jewellery demand dominate.
Platinum demand structure (2024 estimate):
─────────────────────────────────────────
Autocatalysts (diesel cars, heavy vehicles) ~35–40 %
Jewellery (esp. China, Japan) ~25–30 %
Industry (chemicals, glass, electronics) ~15–20 %
Investment (bars, coins, ETCs) ~5–10 %
Other (medicine, hydrogen) ~5 %
─────────────────────────────────────────
Autocatalysts are the single most important segment: platinum oxidises carbon monoxide and unburned hydrocarbons in diesel exhaust into CO₂ and water. The diesel scandal from 2015 onwards and the shift towards petrol cars (which rely more on palladium) noticeably dampened platinum demand from this segment. In the medium term, however, the hydrogen economy – platinum is a key catalyst in fuel cells and electrolysers – could provide fresh demand impetus.
Platinum as an investment metal
Bars and coins
Investment bars of platinum are traded as standard at a fineness of 999.5‰ (also written "Pt 999.5"). Common denominations range from 1 g to 1 kg. Well-known investment coins include:
- Maple Leaf (Canada) – 999.5‰, 1 oz, since 1988
- Vienna Philharmonic (Austria) – 999.5‰, 1 oz, since 2016
- American Platinum Eagle (USA) – 999.5‰, 1 oz, since 1997
- Platinum Koala (Australia, Perth Mint) – 999.5‰, 1 oz, 1988–2000
Tax specifics in Ireland (not tax advice)
Unlike investment gold, which is exempt from VAT under the VAT Consolidation Act 2010 (Schedule 1), this exemption does not extend to platinum. Platinum bars and coins carry the standard Irish VAT rate of 23 %, applied to the full purchase price. This markedly raises the entry hurdle compared with gold. (In Germany, by contrast, platinum is taxed at that country's standard rate and dealers there sometimes use a margin scheme – Ireland offers no such relief.)
For a private individual selling platinum, a gain is chargeable to Capital Gains Tax at 33 %, after the annual personal exemption of EUR 1,270. Ireland grants no holding-period relief, so – in contrast to the German one-year rule under Paragraph 23 EStG – there is no route to selling tax-free after a set period. For a binding assessment, consult a qualified adviser.
Price formation and historical development
The platinum price is quoted in US dollars per troy ounce and set daily on the NYMEX/COMEX and via the LBMA fixing. The historical prices show that platinum traded above gold for decades – a relationship that has inverted since the diesel scandal and rising palladium demand. Platinum currently sits mostly well below the gold price, which is historically unusual.
In a nutshell
Platinum combines extreme rarity with industrial indispensability: without platinum catalysts, clean combustion engines and hydrogen technologies would be hard to imagine. As an investment metal, platinum is more demanding to assess than gold because of its VAT liability and heavy industrial dependence – yet for informed investors it offers a historically favourable entry level.
