Andy Home: ROI-West must set its own prices to avoid China's control of rare earths.

The price of rare Earths has risen sharply, pushing the market price above the minimum price guaranteed by the U.S. government in its groundbreaking deal with domestic producer MP Materials.

The good news is that the U.S. government will not be subsidizing MP Materials' production of neodymium, praseodymium or NdPr as long as the price remains above the critical threshold at $110 per kilogram.

Since signing the agreement with the Department of Defense in July last year, the innovative 'floor-price' mechanism has protected the U.S. National champion from low prices. DoD earns 30% on the price increase.

The problem is that China sets the price reference.

If the West is to break China's stranglehold on rare Earths, they need not only their own production base, but also a market-based pricing mechanism.

CHINESE PRICING Power

According to MP Materials' regulatory filing, the current reference point in the MP Materials-DoD deal is the ex works China NdPr Index compiled by Asian Metal.

A competing Chinese agency, Shanghai Metal Market (SMM), is also referred to in the chart.

China's dominance in the supply chain is reflected in its influence on global rare earths prices. It is the largest physical market for critical metals required to manufacture permanent magnets.

Chinese pricing is inevitably accompanied by Chinese characteristics.

By its nature, a Chinese ex-works will refer to the market dynamics of China. They are diverging from the West's, where the West is trying to develop its own supply chain while China restricts exports.

The way Chinese prices are calculated is a problem.

AM and SMM both provide market data on industrial metals.

Both must adhere to Beijing's legal framework, which is codified in its 1998 Pricing Law.

According to a report from a U.S. Select Committee on China, published in November 2025. Select Committee on China "effectively makes illegal the publication of prices that differ from the PRC Government's wishes."

Escape Clause

The price mechanism in the U.S. Government's agreement with MP Materials contains an escape clause.

If "an internationally recognized alternative index that expresses mid-market prices per ton for NdPr (Pr6O11 25%), Nd2O3 (75%), ex-China is developed," the DoD may elect to change the price reference from AM's assessment.

Both Western price reporting agencies as well as exchanges appear to be aiming for this exact outcome.

Benchmark Mineral Intelligence began collecting prices of rare earths sold outside China. The CME Group, as well as the Intercontinental Exchange, are also studying the possibility of rare earth futures.

LITHIUM TEMPLATE

Lithium is a good example of a template.

Price swings at the Wuxi Exchange in China and, more recently, the Guangzhou Futures Exchange have historically had a great impact on the Western market.

The CME's development of futures contracts for lithium has reduced the dependence on Chinese prices.

The first two years after the CME launched its contract for lithium hydroxide in 2021 saw a minimal turnover.

Activity has increased rapidly since the Western?market matured, and both buyers as well as sellers have sought alternatives to Chinese currency exchange rates.

CME volumes increased by 37% in 2025 compared to the previous year. January's turnover was also a record, with 19,590 contracts.

CME has added to the original contract an option contract, a contract for lithium carbonate, and a contract for spodumene, creating a comprehensive supply-chain suite.

Chinese prices still influence Western pricing, as China is the largest market for lithium and rare earths.

Western lithium companies are no longer completely dependent on Chinese price discovery. They now have the ability to hedge their risk and attract funding for new projects.

TRANSPARENCY

China's pricing power in critical minerals is due to its dominance in both the physical supply chain as well as in price discovery.

For the West to be free, it must address both sides of the issue.

The U.S. Geological Survey has identified 60 minerals as being critical, including lithium and rare earths.

To build Western supply chains, you need to create a complementary market ecosystem.

The price of NdPr in China will determine the fate of both the U.S. taxpayers and government.
