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

The U.S. government's groundbreaking deal with domestic producer MP Materials has resulted in a sharp rise in the price for rare earths.

The good news is that the U.S. government won't have to subsidise the MP Materials' production of neodymium & praseodymium(NdPr), as long as the prices remain above $110 per kilogram.

Since signing the agreement with the Department of Defense in July of last year, the innovative floor-price system has protected the U.S. National?champion against low prices. DoD earns 30% of 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 their own market pricing mechanisms.

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 reflects its influence on rare earths prices globally. It is the largest physical market for critical metals required to make permanent magnets.

Chinese pricing is inevitably accompanied by Chinese characteristics.

By its nature, a Chinese ex-works will be a reference to the?dynamics of the Chinese market. 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 set is even more problematic.

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

The DoD can choose to change the price reference from AM's assessment to the Chinese market if "an internationally recognized alternative index is developed which expresses the middle-market price of NdPr (Pr6O11 25%) and Nd2O3 (75%).

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 China's Wuxi Exchange, and more recently 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 and seller sought alternatives to Chinese exchange prices.

CME volumes increased by 37% in 2025, and the January turnover reached a record of 19,590 contracts.

CME has added to the original contract?with options contracts, a contract for lithium carbonate, and a contract for spodumene, creating an holistic supply-chain products suite.

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

Western lithium companies no longer have to rely 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 designated 60 minerals as critical, including lithium and rare earths.

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

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