What moves the platinum price

The platinum price is the US dollar value of one troy ounce of platinum for immediate delivery. Platinum is about thirty times rarer than gold in the ground, yet it has traded below gold for most of the past decade because its demand is dominated by the car industry. Metal Sentinel returns the live spot quote and day range in 180 or more currencies.

  1. Autocatalyst demand

    Catalytic converters, especially in diesel vehicles, absorb around forty percent of platinum supply. European diesel sales and emissions rules therefore set the tone for the market.

    Diesel sales fall platinum falls

  2. Substitution for palladium

    When palladium trades far above platinum, car makers switch gasoline catalysts toward platinum. That substitution has been a steady source of new demand since the early 2020s.

    Car makers switch from palladium platinum rises

  3. South African supply

    South Africa mines roughly seventy percent of the world's platinum. Power shortages, wage disputes and deep, costly shafts make supply unreliable and keep the market in periodic deficit.

    South African mines stall platinum rises

  4. Hydrogen and investment

    Fuel cells and electrolysers use platinum catalysts, so hydrogen policy affects long-term forecasts. Exchange-traded funds and Chinese jewellery demand swing the short term.

    Hydrogen adoption accelerates platinum rises

About Platinum

What is Pt?

Platinum is a dense, ductile, and highly unreactive precious metal. About 70% of mined supply originates in South Africa, with Russia and Zimbabwe accounting for most of the rest. Most consumption is industrial, led by autocatalysts that scrub diesel emissions. The price is fixed twice daily by the London Platinum and Palladium Market.

Platinum price questions

Questions people ask before they wire the platinum price into a product.

Why is platinum cheaper than gold if it is rarer?

Price follows demand more than scarcity. Gold has central banks and investors as permanent buyers, while platinum depends on car production. When diesel demand fell after 2015, platinum lost its premium over gold.

How is platinum related to palladium?

Both are platinum-group metals mined together and both clean exhaust gases. They are partial substitutes, so a wide price gap between them tends to close over a few years as manufacturers switch.
