The electric vehicle transition is the most discussed long-term risk to rhodium prices. Battery electric vehicles (BEVs) use absolutely no rhodium. But with 1.4 billion internal combustion engine (ICE) vehicles on the road, hybrid vehicles surging, and emerging markets adopting EVs slowly, how fast will rhodium demand actually fall?
Let's start with the absolute certainty: Battery Electric Vehicles (BEVs) like a Tesla Model Y or BYD Seal do not have an internal combustion engine, produce no exhaust, and therefore have no catalytic converter. They require exactly zero grams of rhodium, platinum, or palladium.
Every time a consumer buys a BEV instead of a petrol car, the global rhodium market loses approximately 0.4g to 0.6g of demand. Over time, this is a structural, permanent destruction of rhodium demand.
In 2026, BEVs account for roughly 15-18% of all new light vehicle sales globally. However, this adoption is highly asymmetrical:
To understand the price impact, we have to quantify how many EVs it takes to move the needle on a 30-tonne-per-year rhodium supply base.
Global light vehicle production is approximately 85 million units per year.
A 1 percentage point increase in global BEV market share equals ~850,000 fewer ICE vehicles produced.
At a global average loading of ~0.5g of rhodium per ICE vehicle, those 850,000 vehicles would have consumed ~425 kg of rhodium.
425 kg represents roughly 1.4% of total annual global rhodium supply (~30,000 kg).
If global BEV share grows by 2% per year, rhodium demand falls by roughly 2.8% per year (all else being equal). While this is a clear negative trend, it is not a cliff-edge drop. It is a slow bleed that takes over a decade to halve global demand, giving South African miners significant time to adjust production or for other factors to intervene.
The narrative that EVs will kill rhodium demand by 2030 suffers from extreme Western bias. It ignores the developing world.
India produces over 4 million passenger vehicles a year and is growing rapidly. It recently implemented strict BS6 emission standards, requiring heavy rhodium loadings. BEV adoption in India remains negligible for passenger cars due to high battery costs and lack of charging infrastructure. Similar dynamics exist across Southeast Asia, Africa, and Latin America.
These markets will continue to build and buy millions of rhodium-bearing petrol vehicles well into the 2040s, providing a massive buffer against demand destruction in Europe and China.
Many consumers buy Plug-in Hybrid Electric Vehicles (PHEVs) believing they are part of the EV revolution. The rhodium market sees them differently: PHEVs are ICE vehicles that carry a battery.
Because a PHEV has a petrol engine, it must have a full catalytic converter system to pass emission tests. Real-world data from organizations like the ICCT (International Council on Clean Transportation) show that PHEV owners charge their vehicles far less than expected, relying heavily on the internal combustion engine.
Furthermore, because PHEV engines turn on and off frequently, the catalytic converter cools down. Cold starts generate massive NOx spikes, forcing automakers to use more rhodium or electrically heated catalysts to ensure compliance. A booming PHEV market is actually highly supportive of rhodium demand.
The EU, UK, and California have legislated bans on the sale of new ICE vehicles by 2035. However, these bans only apply to new vehicle sales in those specific jurisdictions. They do not force the scrappage of existing vehicles.
There are over 1.4 billion ICE vehicles on global roads today. Even if Western 2035 bans hold firm (and political pushback makes delays possible), rhodium demand will persist strongly through 2030, and the massive installed base will guarantee a robust secondary market (recycling) for decades.
Pure Battery Electric Vehicles (BEVs) like Teslas use absolutely no rhodium. They have no exhaust, so they do not need catalytic converters. However, Hybrid Electric Vehicles (HEVs) and Plug-in Hybrids (PHEVs) still have combustion engines and therefore still require full rhodium-bearing catalysts.
EV adoption is already shaving small percentages off global rhodium demand. However, because global vehicle production is so large (~85M/year), it will take until roughly 2030-2032 for EV market penetration to destroy enough ICE demand to fundamentally break the rhodium market, assuming mine supply remains stable.
China is the most critical market. China produces ~30 million vehicles a year and has strict China VI emission standards. The rapid adoption of EVs in China (~40% market share) is currently the biggest single headwind for global rhodium demand.
Hydrogen Fuel Cell Electric Vehicles (FCEVs) use catalysts, but they primarily use platinum to facilitate the chemical reaction in the fuel cell. They do not use meaningful amounts of rhodium. FCEVs are neutral for rhodium demand.
Extremely slow for passenger cars (under 3% market share). India is a highly price-sensitive market where EV battery costs remain prohibitive, and charging infrastructure is scarce. Because India recently mandated strict BS6 emission standards requiring high rhodium use, India's growing ICE fleet is a major buffer keeping global rhodium demand high.
In the very long term (10-15 years), yes—the total addressable market for rhodium will shrink permanently as the ICE fleet declines. However, in the short-to-medium term, tightening emission standards on the remaining ICE vehicles, hybrid growth, and South African mine constraints can easily overpower the EV demand destruction, causing massive price spikes.
