Andy Home: Demand destruction could help China break its rare earths shackles

Beijing's export restrictions have exposed the West's dependence on Chinese supplies of esoteric materials and permanent magnets.

It's not like we've never been in this situation before. China did the exact same thing in 2010.

Western automakers chose to ignore historical precedents and double down on a techniqe that is almost completely beholden Beijing's export whims.

Many of them have now entered a panic mode and several have already been forced to stop production lines. This shows the huge economic impact that niche metals like dysprosium (used in neodymium iron boron (NdFeB), magnets) can make.

China's willingness weaponise its dominant position in the metals which power our modern world, will accelerate the West’s drive to develop its own supply chain.

The solution lies in using less rare earths. The West cannot control the supply but can change demand.

The past is not for those who forget it.

Beijing said that its 2010 imposition of rare Earth export quotas was only to clamp down on illegal domestic mining.

The incident happened after a collision in disputed waters between a Chinese coast guard vessel and a Chinese trawler.

The entire West was affected by the skyrocketing prices of rare Earths if Japan were the target. According to Adamas Intelligence, the price of dysprosium oxide increased 26-fold between 2009 and 2012.

China only reversed its position after a panel of the World Trade Organization ruled against them in 2014.

Several automakers have learned the lesson.

Nissan Motor Co. of Japan launched in 2012 a new LEAF electric car with a motor that contained 40% less dysprosium.

Renault developed an alternative motor for its ZOE in the same model year, without permanent magnets or rare earths.

Adamas estimates that the number of EVs with rare-earth free motors grew from less than 1% in global sales in 2010, to 12% by 2017.

This was the pinnacle.

BUCKLE UP

Prices of rare earths fell in late 2010s and remained steady. Western automakers have largely switched back to permanent magnetics.

According to Adamas, around 97% of the EVs sold each year since 2017 have rare-earth motors.

The rapid growth of the EV market, especially in China (which for obvious reasons does not have a rare earths phobia), is reflected in the number of magnets that are used in new vehicles, whether they be pure battery or hybrid.

Magnets are also used to control heating, entertainment, braking, and remind the driver of their seat belt.

This has increased the dependence on a single country, which not only produces 95% of all NdFeB magnetic products in the world but also controls supply chains for the metals needed to produce them.

PEACE TALKS

China's rare earth exports may have been pushed too far this time, possibly because of an overzealous bureaucracy in the Ministry of Commerce that is responsible for segregating military from civilian applications.

The talks between Chinese and U.S. officials entered their second session on Tuesday, in an effort to find a compromise between China's restriction on rare earths and U.S. limitations on advanced semiconductors. Background: Tariffs are a major factor.

The automotive industry will remain dependent on rare earths even if Beijing eases up its restrictions.

It may take a while for Western supplies to catch up. Even though Western governments pour money into new projects to build a mine-to magnet supply chain, it will take years.

Civil sectors will also be second. The U.S. Department of Defense is the largest investor in rare earths, with a stated goal of supporting "all U.S. Defense requirements by 2027".

The speakers in your car radio are not as powerful as the magnets required for an F-35 fighter. This aircraft requires over 900 pounds worth of rare earths.

DEMAND DESTRUCTION

Does the technology used in non-critical applications really need to be deployed on new vehicles?

A bigger question is if they need a rare earth magnet in the engine.

Renault and BMW, which have learned from their past mistakes, have developed alternatives for their EV motors to reduce the impact of this current supply crisis.

Many other automakers have also been interested in the technology, but it is not yet ready for commercial production.

China's recent restrictions on rare earths should serve as a powerful motivation to speed up the redesign process.

When it comes to breaking free of China's chokehold over rare earth magnets, automakers may find that engineered demand destruction is faster than creating a new supply network.

It's not like they've never done it before.
