The dynamics of platinum group metal substitution are shifting as the price gap between platinum and palladium narrows. During 2023–2024, platinum traded at a $500–$1,000/oz discount to palladium, incentivizing automakers to substitute platinum for palladium in gasoline catalytic converters. This substitution was a key driver of platinum’s demand growth.
With platinum now at $1,754/oz and palladium trading near $1,850/oz, the spread has collapsed to approximately $100/oz. At this level, the cost savings from substitution are minimal, especially considering the engineering and certification costs associated with changing catalyst formulations. The incremental substitution-driven platinum demand is therefore largely exhausted.
Palladium’s recent weakness relative to platinum reflects its own fundamentals: palladium has been in surplus since 2024 as Russian supply remains resilient and auto demand growth has plateaued. The narrowing spread is therefore more a story of palladium weakness than platinum strength.
Looking forward, the structural growth driver for platinum remains hydrogen fuel cells and electrolyzers, which could add 875–900 koz of demand by 2030. However, in the near term, this is a distant catalyst that has limited price impact. Without the substitution tailwind, platinum demand in 2026 is largely dependent on automotive and industrial end-use, neither of which shows strong growth momentum.
The narrowing platinum-palladium spread removes the substitution-driven demand support for platinum. Buyers should assess palladium as a potential alternative in procurement strategies, as near-parity pricing creates flexibility. For long-term contracts, consider pricing mechanisms that track both metals given the increased correlation.
