Rhodium has one of the most concentrated supply profiles of any critical industrial metal. Unlike platinum or palladium — which have meaningful production from Russia, Zimbabwe, and North America — rhodium's supply is overwhelmingly tied to the stability of South Africa's PGM mining complex, specifically the Bushveld Igneous Complex. This creates a structural vulnerability that no amount of recycling can fully offset.
Johannesburg — In the world of critical minerals, few supply chains are as precariously concentrated as rhodium's. An estimated 85% of global rhodium production originates from South Africa, with the vast majority extracted as a by-product of platinum and palladium mining in the Bushveld Igneous Complex. Russia accounts for roughly 10%, primarily from Norilsk Nickel's operations, with Zimbabwe and recycling making up the balance.
This concentration is not by design but by geology. Rhodium occurs at extremely low grades — typically just 0.2 to 0.5 grams per ton of ore — and is almost never mined as a primary product. Instead, its production is a captive by-product of platinum and palladium mining, meaning supply is almost entirely inelastic to rhodium's own price signals.

"New rhodium production does not simply ramp up in response to higher prices; it is locked into PGM mining cycles that take many years to adjust," notes Strategic Metals Invest. This supply rigidity means that any disruption in South Africa — whether from energy shortages (load-shedding), labor strikes, mine closures, or regulatory changes — can cause immediate and violent price spikes.
Johnson Matthey's latest report underscores the fragility: South African PGM supplies are expected to experience a modest decline in 2026, driven by a smaller benefit from the release of work-in-progress than in the prior two years, combined with continuing contraction in underlying mine production. Meanwhile, Russian supplies are expected to contract sharply as Norilsk Nickel's output shifts due to changes in mining mix.
Unlike gold, silver, or even platinum and palladium, rhodium has no active futures market and no centralized exchange. Prices are determined through bilateral negotiations among a small group of industrial suppliers, refiners, and consumers — primarily Johnson Matthey, Heraeus, and Umicore. The benchmark Umicore fixing price, published daily at 10 a.m., is the closest the market has to a transparent reference point.
This opacity amplifies every supply-side risk. A single mine shutdown in South Africa's Limpopo province, a port disruption at Durban, or an escalation in the country's endemic electricity supply issues could instantly reshuffle the global supply-demand balance — and with it, the price.
Recycling now contributes an estimated 20–25% of global rhodium supply, and that share is growing. Johnson Matthey forecasts double-digit growth in autocatalyst recycling this year, a key factor in the projected swing to surplus. However, even at elevated recycling rates, secondary supply remains tethered to the legacy fleet of ICE vehicles — and the collection and processing infrastructure is also heavily concentrated in Europe and North America.
"The recovery in autocatalyst recycling is positive, but it does not eliminate the concentration risk," one industry analyst noted. "South Africa remains the lynchpin. If the primary supply chain there is disrupted, recycling alone cannot fill the gap."
For traders and industrial buyers, South Africa's dominance means that the current surplus projection could be rapidly invalidated by a single supply event. The 2025 deficit of 50,000 oz was driven partly by constrained South African output. A similar disruption in 2026 could flip the forecast 15,000 oz surplus back into a deficit, reigniting the kind of price rallies that took rhodium from $6,500/oz to $11,500/oz in just over a year.
Heraeus has projected that rhodium prices trade in a reset-low environment in early 2026, but the firm also acknowledges that the metal's extreme supply concentration creates constant upside tail risk. As the old adage in PGM markets goes: when rhodium moves, it does not walk — it jumps.
• South Africa: ~85% of global mined rhodium (Bushveld Igneous Complex)
• Russia: ~10% (Norilsk Nickel by-product)
• Recycling: 20–25% of total supply (growing, but constrained)
• Number of major price-setting refineries: 3 (Johnson Matthey, Heraeus, Umicore)
• Futures market: None — no centralized exchange for price discovery
• Supply elasticity: Extremely low — mining cycles measured in years
