A growing concern is emerging across the global auto industry. As China moves to strengthen its control over rare earth exports, automakers are becoming increasingly aware of how vulnerable their supply chains are — and how easily production could be disrupted.
Toyota executive Ryan Grimm highlighted the issue clearly:
“They can shut us down in two months — the entire auto industry.”
The Invisible Materials That Power Everything
Rare earth elements might sound obscure, but they’re the invisible force behind modern cars. They make the magnets that move your side mirrors, power your speakers, and even help control oil pumps and braking sensors. For electric vehicles, they’re absolutely indispensable — the heart of the motor itself.
And China controls almost all of it. Around 70% of global mining, 85% of refining, and a staggering 90% of magnet production happen under Beijing’s watch. When China decides to slow or stop exports, the rest of the world simply can’t keep up.
A Race Against the Clock
With new export restrictions taking effect on November 8, automakers are scrambling. Orders are being rushed, warehouses filled, and supply teams are in overdrive trying to build a safety cushion. But it might not be enough. Even if shipments leave China today, they take up to 45 days to reach Europe — and by then, the gates may already be closed.
“The situation is very tense,” said Nadine Rajner, CEO of German supplier NMD. “We’re pretty much sold out and have limited stocks.”
Bosch and Hyundai suppliers are reporting the same: stockpiles are drying up fast. Some companies are even “overstocking” rare earths out of fear, while others admit their inventories have already vanished.
Why Everyone Depends on China
The uncomfortable truth is that no one else can match China’s scale. Even countries rich in rare earth deposits, like Sweden, lack the refineries to turn raw material into usable components. And for heavy rare earths — the kind most critical for EVs — China controls an astonishing 99.8% of global refining capacity.
Europe and the U.S. have been slow to react. Recycling offers a glimmer of hope — Renault-backed Neutral is already reclaiming rare earths from old cars — but that effort is still small. “The challenge is scaling up,” said CEO Jean-Philippe Bahuaud.
Fighting Back with Innovation
Carmakers are trying to break free. BMW and Renault have already developed motors that don’t rely on rare earths, while GM, BorgWarner, and ZF are working on next-generation electric motors that use less of them.
In the UK, Monumo is using AI simulations to help manufacturers cut their rare earth use by nearly a quarter. But as promising as these solutions sound, most are still years away from mass production.
And even if new mines or technologies emerge, China could still crush competition simply by slashing prices — something it’s done before. “The Chinese can always undercut them,” said industry expert Andy Leyland. “It’s a really risky investment.”
A Power Move That Shakes the World
To many in the industry, this isn’t just about materials — it’s about power. By controlling rare earths, China has built a chokehold over one of the world’s most valuable industries. And with its growing influence over battery and chip production too, its leverage is only getting stronger.
“This is not the end of export controls,” warned Jan Giese from Tradium, a major rare-earth trader. Most experts agree — this is just the beginning.
So when Toyota’s Grimm says China could stop the auto industry in two months, he’s not exaggerating. The world’s most advanced factories could fall silent, not for lack of talent or technology — but because of a few rare metals buried deep beneath Chinese soil.
