Rhodium Market in Fragile Balance as EV Transition Reshapes Autocatalyst Demand

The rhodium market is experiencing its most significant structural transition in a generation. After 14 years of deficit that drove prices to a record $29,500/oz in 2021, the market is moving toward balance as EV adoption reduces the number of new gasoline vehicles requiring rhodium-containing three-way catalysts. Rhodium is an essential component of the autocatalyst formulation — no substitute metal provides the same NOx reduction efficiency.

The pace of the transition has been moderate. Global rhodium demand declined to approximately 980,000 ounces in 2025, down from 1.1 million ounces in 2019. The 11% decline over six years is significantly less severe than the 37% reduction in palladium autocatalyst demand over the same period, reflecting rhodium's smaller loading per vehicle and the lack of viable substitutes for its catalytic properties.

Supply conditions remain supportive. South Africa — which produces 83% of global rhodium — continues to face structural challenges. Amplats' Mogalakwena mine, the world's largest PGM operation, is undergoing shaft refurbishment expected to persist through Q3 2026. Total South African PGM output declined 2.5% in Q1 2026, with rhodium production proportionally affected. Russian rhodium supply from Nornickel also declined 3% year-on-year.

The secondary supply market is a growing factor. Rhodium recycling from end-of-life autocatalysts contributed 185,000 ounces in 2025, up from 160,000 ounces in 2023, as improved recycling technology and collection networks increase recovery rates. However, the autocatalyst recycling stream has a 10-15 year lag relative to new vehicle production, meaning that the reduction in new vehicle sales will only flow into recycling volumes with a significant delay.
