Rhodium supply is under acute pressure from structural challenges in South Africa's PGM mining sector. Shaft rationalizations by major producers — including Anglo American, Impala Platinum, and Sibanye-Stillwater — have removed significant rhium-bearing production capacity. The Eskom power crisis adds operational costs and uncertainty to deep-level mines that already rank among the world's most complex and expensive to operate.
The supply concentration risk is extreme: more than 80% of global rhodium comes from South Africa's Bushveld Complex, with most as a by-product of platinum mining. This means rhodium supply is almost entirely dependent on platinum mining economics. When platinum mines close shafts to cut costs, rhodium supply falls regardless of rhodium's own price. This structural by-product dependency creates a perpetual supply risk premium in rhodium pricing.
Historically, periods of rhodium supply disruption — whether from mine accidents, labor strikes, or Eskom grid failures — have triggered price spikes of 50-200% within weeks. The market is thin, with annual demand of approximately 800,000-1,000,000 ounces against supply that has been structurally declining. The combination of Euro 7/China 7 demand support and constrained South African supply creates a bullish setup for the metal heading into 2027.
