Rhodium at $8,200/oz on July 10, steady for the week, according to Johnson Matthey. The metal surged 94.7% in 2025 and has stabilized in a $7,800-8,800 range since March 2026. At current levels, rhodium is 54% below its 2021 peak of $17,500/oz but 116% above start-of-2025 levels.
The rhodium market is expected to shift from a small deficit of roughly 10,000 oz in 2025 to a small surplus of about 15,000 oz in 2026, according to Heraeus and Metals Focus. That is a razor-thin balance in absolute terms — annual demand is roughly 310,000 oz — but a shift in direction nonetheless. The surplus is driven by two factors: declining ICE vehicle production (rhodium is used almost exclusively in gasoline catalytic converters) and higher recycling efficiency.
South Africa is the supply story. Over 83% of global rhodium output is a by-product of platinum and palladium mining in the Bushveld Complex. This means rhodium supply does not respond to rhodium prices — it follows platinum and palladium mining decisions. When South African mines cut PGM production (as Amplats and Impala are doing), rhodium supply declines proportionally. The supply curve is completely inelastic in the short term.
Automotive catalysts account for roughly 71-74% of rhodium demand, and there is no substitute technology at scale. Rhodium is essential for reducing NOx emissions in gasoline engines. Electric vehicles do not need catalytic converters, which is the long-term bear case, but the ICE fleet is still 1.4 billion vehicles and replacement demand for catalytic converters will remain significant for another decade.
The key insight is that rhodium is not a binary shortage/surplus story. At current prices, the market is balanced. Recycling efficiency is improving with better catalyst collection, adding roughly 5,000-8,000 oz of supply per year. But new mine supply is static to declining. The small surplus projected for 2026 could flip back to deficit in 2027 if South African production tightens further.
Bull case: South African production falls faster than expected, recycling growth plateaus, and ICE production holds steady. Rhodium retests $10,000.
Bear case: BEV adoption accelerates, ICE share drops below 75% of global sales, and the surplus widens. Rhodium falls to $5,000.
Base case: Rhodium holds $7,500-8,500 for the balance of 2026, balanced between declining ICE demand and constrained by-product supply.
Rhodium procurement is a niche but high-stakes category for automotive buyers and chemical catalyst users. The market is balanced, which means there is no urgency to lock in large volumes at current prices. For buyers with ongoing rhodium requirements, the best strategy is floating-price contracts indexed to Johnson Matthey or Heraeus published prices, with volume commitments but no fixed price. The small surplus gives buyers a negotiating advantage. The wildcard is South Africa — any deterioration in Eskom power supply or mine labor conditions could trigger a price spike regardless of the surplus. Buyers should maintain 4-6 weeks of safety stock on-site. Do not hedge financially in rhodium — the market is too thin and the bid-ask spread too wide.
