Euro 7 and China 7 emissions standards are breathing new life into rhodium demand. The tighter NOx and particulate matter limits require higher PGM loadings in both gasoline and diesel catalytic converters, with rhodium being the most effective metal for NOx reduction. The regulations are creating a meaningful demand boost for a metal that had been under pressure from automotive electrification fears.
Rhodium is currently trading in the $9,000-10,000 per ounce range, a level that reflects both the demand support from tighter emissions standards and the extreme supply concentration risk. South Africa accounts for more than 80% of global rhodium production, primarily as a by-product of platinum mining. The same shaft rationalizations and power shortages affecting platinum and palladium production apply equally to rhodium, with supply constraints providing a structural floor.
The market remains highly sensitive to any supply disruptions. Rhodium's extreme volatility — the metal has traded from $4,000 to $29,000 and back within the last five years — means that any South African power crisis, mine closure, or labor disruption can trigger rapid price swings. The Euro 7 and China 7 demand boost provides fundamental support, but the metal's thin market and concentrated supply mean pricing will remain volatile.
