About Rhodium

Rhodium is the rarest and most valuable of the platinum group metals, primarily used in three-way catalytic converters for gasoline vehicles where it reduces nitrogen oxide emissions. South Africa produces approximately 80% of global supply. Rhodium prices have historically been the most volatile of any precious metal due to its extremely thin market and lack of substitutes in autocatalysts.
