Imagine one metal so precious that its value exceeds that of gold by almost twenty times. This is rhodium, a rare and essential element for several industries, which is facing an alarming shortage.
Currently priced at US$29.800 per ounce (approximately R$142.900, considering the June 2024 price), rhodium is vital for the automotive sector, where it is used in catalysts to reduce harmful emissions. The supply crisis for this metal raises significant concerns about the future of many technologies.
Rhodium and its Utilities: A Jewel of the Automotive Industry
Rhodium stands out for its unique chemical properties, being extremely effective in neutralizing polluting gases emitted by vehicles.
Thanks to rhodium, automotive catalysts can transform toxic gases into substances that are less harmful to the environment. This critical use makes rhodium an indispensable component, especially in times of increasing stringency in environmental regulations.

Where It’s Found: A Valuable Byproduct
Rhodium production is complex and limited. Mainly mined as a byproduct of platinum mining in South Africa and nickel in Russia, rhodium faces tight supply.
South Africa is responsible for approximately 80% of global rhodium production, making it a key country in the market for this precious metal. However, South African production has suffered from challenges such as strikes, political instability and high costs, impacting global supply.
The Rhodium Price Rollercoaster
Historically, rhodium prices have shown extreme volatility. According to experts, rhodium reached its peak in 2022, selling for US$29.800 (approximately R$142.900) per ounce, a significant increase compared to the US$639 (approximately R$3.065) recorded in 2016.
This fluctuation reflects market uncertainties and the difficulty in maintaining a constant supply. Investors are watching closely, aware that environmental regulations and industrial demand could drive further price increases.
Impact in Brazil: Exploring the Potential
In Brazil, rhodium mining is still in its initial phase, but the country has the potential to explore this market. According to geological studies, there is evidence of platinum and nickel deposits that could eventually include rhodium as a byproduct.
The development of this exploration could represent a new source of revenue for the Brazilian mineral industry, in addition to contributing to the global supply of the metal.
Challenges and Future Perspectives
The rhodium shortage not only generates price volatility, but also puts pressure on the search for alternatives.
According to experts, recycling used catalysts is one of the most promising solutions, reducing dependence on new extractions. However, according to these experts, the economic and technical viability of recycling still faces significant obstacles.
Additionally, we bring Research is underway to develop catalysts that use less rhodium or other materials. Meanwhile, industry continues to rely heavily on this metal, especially in the automotive and electronics fields.
In this sense, experts assess that the rhodium crisis illustrates the challenges faced by an industry dependent on rare materials and difficult to extract. With fluctuating prices and limited supply, rhodium's future remains uncertain, but its strategic importance is undeniable.
Because of this, investors, scientists and industries are closely watching the next steps in the saga of this precious metal, aware that its unique properties are irreplaceable in the current technological and environmental scenario.
