Goldminr: Rhodium vs. Platinum: Which PGM Offers Better Returns in the Current Market?

The world of precious metals is vast and complex, offering investors a range of options, each with its own unique characteristics and potential for returns. Among these, platinum group metals (PGMs) like rhodium and platinum stand out due to their rarity and critical industrial applications. As of December 2025, the question on many investors’ minds is: which of these PGMs, rhodium or platinum, offers better returns in the current market?

Understanding PGMs: Rhodium and Platinum

Before diving into the specifics of investment returns, it’s essential to understand what rhodium and platinum are and what factors influence their prices.

Platinum: Platinum is a silverish-white metal that is ductile, malleable, and highly unreactive. Its versatility is evident in its wide range of applications, with the automotive sector accounting for the highest percentage (43%) of global platinum consumption. Platinum, along with palladium and rhodium, is used to coat the ceramic hearts of catalytic converters, devices that reduce harmful emissions from vehicles. The jewelry industry consumes about a quarter of the annual platinum demand, prized for its lustrous appearance and hypoallergenic properties.
Rhodium: Rhodium is an ultra-rare, silver-white metal that is highly reflective and corrosion-resistant. It is one of the rarest elements in the Earth’s crust, making it even more scarce than platinum and gold. The primary use of rhodium is in automotive catalytic converters, where it reduces the amount of nitrogen oxides (NOx) exhaust gases emitted into the atmosphere.

Factors Influencing Rhodium and Platinum Prices

The prices of rhodium and platinum are influenced by a complex interplay of supply and demand dynamics, geopolitical events, economic indicators, market sentiment, and technological advancements.

Supply and Demand: The fundamental driver of any commodity price is the balance between supply and demand.
- Platinum: Platinum’s price is significantly influenced by the automotive industry, where it is used in catalytic converters to reduce emissions. As countries push for cleaner emissions, the role of platinum in catalytic converters becomes even more crucial, driving its demand and price upwards. Disruptions in major producing regions due to geopolitical tensions or labor strikes can impact the supply chain and lead to price spikes.
- Rhodium: The pricing of rhodium is influenced by its rarity, demand in various industries, and the limited nature of its sources. The automotive industry’s reliance on rhodium for emission control plays a significant role in driving its demand and price. Disruptions in South African mines due to political, social, or natural factors could significantly impact global supply and push prices higher.
Geopolitical Factors: Political instability in major platinum and rhodium-producing countries, such as South Africa and Russia, can significantly impact prices by disrupting the supply side of the commodity. Trade policies and tariffs can also create fluctuations in supply and demand, affecting market prices.
Economic Indicators: Economic indicators such as interest rates and inflation rates can influence the demand for platinum and rhodium. High inflation rates may drive investors to seek refuge in precious metals as a hedge against currency devaluation.
Market Sentiment and Speculation: Investor behavior and speculation can also play a role in price fluctuations. Expectations of future supply shortages or demand increases can lead to speculation, causing prices to rise.
Technological Advancements: Technological advancements in catalytic converter technology and the development of alternative technologies, such as electric vehicles, can impact the demand for platinum and rhodium.

Rhodium vs. Platinum: Recent Performance and Forecasts

To determine which PGM offers better returns, it’s crucial to analyze their recent performance and consider expert forecasts.

Platinum: Platinum began the year trading between US$900 and US$1,100 per ounce and has experienced an upward trend, propelled by strong fundamentals. Demand for platinum is expected to outstrip supply by a considerable margin, with the World Platinum Investment Council (WPIC) predicting a deficit of 966,000 ounces this year, following a 992,000-ounce shortfall in 2024. Gains in platinum demand largely came from a more than 300 percent rise in investment. Jewelry makers are beginning to use platinum instead of gold as the price of the yellow metal trends near all-time highs.
Rhodium: Rhodium prices have surged in 2025, driven by supply deficits and hybrid vehicle demand. Trading Economics reported a YoY increase of 57.53%, with prices at $7,325/oz in September 2025. Johnson Matthey predicts a 2025 rhodium market deficit, with prices projected to rise to $7,733/oz by late 2025.

Metals Focus expects average prices for platinum and rhodium to rise by 1% and 8%, respectively, in 2025.

Investment Risks and Considerations

Investing in rhodium and platinum carries inherent risks that investors should carefully consider.

Volatility: Both rhodium and platinum prices can be highly volatile due to supply and demand dynamics, geopolitical tensions, and economic conditions.
Market Liquidity: The market for physical platinum and some ETFs is smaller than for gold, which can impact liquidity and market depth.
Industrial Demand Dependence: Platinum and rhodium are sensitive to automotive trends, making them vulnerable to changes in the industry, such as the shift to electric vehicles.
Geopolitical Risks: Production is geographically concentrated, which raises the risk of mine disruptions and political or regulatory challenges.

Strategies for Investing in Rhodium and Platinum

Investors have several options for investing in rhodium and platinum, each with its own set of advantages and disadvantages.

Physical Bullion: Investors can purchase platinum and rhodium bars or coins from dealers and store them securely. This option provides direct ownership of the metal but may involve storage costs and security concerns. Note that rhodium bullion coins are not available due to the metal’s properties.
ETFs: Exchange-traded funds (ETFs) offer exposure to platinum and rhodium prices without the need to own the physical metal. They are more liquid and accessible but come with management fees.
Mining Stocks: Investing in companies engaged in platinum and rhodium mining and production can provide diversification but also carries company-specific risks.

Conclusion

As of December 2025, both rhodium and platinum present compelling investment opportunities in the PGM market. Rhodium, driven by its scarcity and critical role in emissions control, is expected to outperform platinum and palladium in price appreciation. However, its higher volatility and concentrated supply chain demand careful risk management. Platinum, with its growing industrial and investment demand, offers a more stable yet still promising outlook.

Ultimately, the decision of whether to invest in rhodium or platinum depends on an investor’s individual risk tolerance, investment goals, and understanding of the market dynamics. Diversification, thorough research, and staying informed about market trends are crucial for navigating the PGM market and maximizing returns.
