Palladium demand is undergoing a structural transition as two key forces reshape the autocatalyst market: substitution by lower-cost platinum and the long-term erosion of internal combustion engine vehicle production due to EV adoption.
The palladium-platinum price differential has inverted from historical norms. Traditionally, platinum traded at a premium to palladium. Today, palladium at approximately $814/oz trades near parity or even at a discount to platinum, making substitution commercially attractive for automakers.
Platinum can replace palladium in gasoline catalyst formulations to varying degrees, with some estimates suggesting up to 30-50 percent substitution is technically feasible. Automakers have been progressively increasing platinum loading in new catalyst designs, a process that accelerates when the substitution provides meaningful cost savings.
EV adoption, while growing rapidly to approximately 25 percent of global new vehicle sales, still leaves 75 percent of vehicle production using internal combustion engines that require palladium-containing catalysts. The transition is multi-decade, and near-term palladium demand from ICE production remains substantial.
