In 2010, China cut off rare earth exports to Japan for two months. The trigger was a fishing boat fight near a chain of islands in the East China Sea. Japan's factories — the ones that made hybrid car motors, hard drives, and wind turbines — ran on rare earth magnets. When the supply stopped, so did the machines. Japan spent the next decade building stockpiles so it would never get caught again.

Sixteen years later, the same fear has reached the chip fabs. Every chip TSMC makes starts with a machine that moves. Robotic arms load wafers. Belts shuffle trays. Motors spin at thousands of RPMs in clean rooms the size of football fields. And inside nearly every one of those motors sits a small block of rare earth magnet. Neodymium. Iron. Boron. Made in China.

That is the problem TSMC just decided to fix. Reuters reported on October 22 that the world's biggest chipmaker has started asking its suppliers a blunt question: can you build us motors that run without rare earth magnets? Three people close to the talks confirmed it. TSMC would not comment.

The timing is not random. China's 12-month pause on its October 2025 export controls expires on November 10. No extension has been published. If Beijing turns those rules back on, any product with more than 0.1% Chinese rare earth content could need a new license. That means the magnets inside the motors inside the machines inside TSMC's fabs. One snag could slow chip output for Apple, Nvidia, and the Pentagon at the same time.

So TSMC is planning ahead. The question is simple: can motors that use copper coils instead of rare earth magnets run a chip fab? Two designs fit the bill — induction motors and switched reluctance motors. Neither uses rare earths. But neither matches the torque and speed of the magnets they would replace. Rare earth magnets pack more power per kilogram than anything else. That is why they ended up in every factory on Earth. Taking them out means bigger motors, lower efficiency, or both.

China controls roughly 70% of rare earth mining, 90% of refining, and 94% of finished permanent magnets. TSMC's move shows that even the most advanced company on Earth still depends on a supply chain that runs through one country. And the clock is ticking. November 10 is fifteen days away.

TSMC is not the only one paying attention. The SMM weekly review noted that ex-China rare earth prices edged lower this week on sluggish trading. But the bigger picture is hard to miss. Every major buyer of rare earth magnets is now asking the same question: what happens if China's pause ends? The fabs run on magnets. The magnets come from China. And China has not said what comes next.

In April 2026, Elon Musk announced he was partnering with Intel.

The result?

Shares took off…

And were trading 177% higher just two months later.

I believe Elon is about to announce a NEW partnership with this little-known company…

To work on what he called "the most epic AI project in history."

But you need to act fast…

Because Elon has already approached this company.

I believe he's going to make it official by October 30…

Which should send shares higher than anyone can imagine.

Malaysia approved a batch of unprocessed rare earth ore for export — the first time the country has allowed it under a new framework that went live this month. The buyer was not named. Lynas Rare Earths is the only big producer working in Malaysia outside China, and more than a dozen US firms are looking at deals there. The new rules tie exports to pledges on local refining and tech sharing. That is a shift. Malaysia banned raw exports in 2024. Now it is letting small lots leave if the deals bring refining jobs back. France's Carester and Malaysia's Malaco Mining are already planning a rare earth plant in the northern state of Perak.

A new study from GEM Mining Consulting says Chile's push into rare earths has a gap in the middle. The country has mines and a new demo plant that turns oxides into metal — but no large-scale plant to split mixed rare earths into pure forms. GEM found that projects outside China could meet only 25% of the world's non-Chinese refining needs by 2035. Plants outside China cost 20% to more than 150% more to build and about 50% more to run. Aclara's Penco clay deposit in the Biobío region just got a new after-tax net present value of $344 million. But the company plans to ship its output to Louisiana for refining, not do it at home. Chile has the rocks. What it does not have is the middle of the chain.

China's October 2025 export controls were frozen for 12 months. That freeze ends November 10. No one has published a renewal. If the pause lapses, rules on five more rare earths, lithium batteries, graphite, and any product with more than 0.1% Chinese rare earth content all snap back. The April 2025 permit rules for seven heavy rare earths — dysprosium, terbium, gadolinium, samarium, lutetium, scandium, and yttrium — never paused at all. Total Chinese rare earth exports fell 9.6% to 43,711 tonnes in the first nine months of 2026, even as September alone rose 6.7% year on year.

Union Minister G. Kishan Reddy arrived in Sydney on October 25 for talks on mining deals, rare earths, and lithium. India and Australia signed a minerals pact in 2020. This trip aims to turn those pacts into real money.

The Pentagon added $4.6 million for samarium and gadolinium work at Ucore's plant in Alexandria, Louisiana. Total grants from the U.S. government now stand at $27 million. Samarium-cobalt magnets hold up at high heat, which is why the military wants a U.S. source. Ucore aims to start running its first full-scale unit in the first half of 2027.
