Rare earth metals have a wide variety of applications, including for magnets in medical technology, defense, and energy productssuch as wind turbines and electric motors.
Jacquez told me there has been “years of work, including by the first Trump administration, that has pointed to this exact case as the worst-case scenario that could happen in an escalation with China.” It stands to reason, then, that experienced policymakers in the Trump administration might have been mindful of forestalling this when developing their tariff plan. But apparently not.
“The lines of attack here are numerous,” Jacquez said. “The fact that the National Economic Council and others are apparently just thinking about this for the first time is pretty shocking.”
And that’s not the only thing the Trump administration is doing that could hamper American access to rare earths and critical minerals.
Though China still effectively controls the global pipeline for most critical minerals (a broader category that includes rare earths as well as more commonly known metals and minerals such as lithium and cobalt), the U.S. has been at work for at least the past five years developing its own domestic supply chain. Much of that work has fallen to the Department of Energy, whose Loan Programs Office has funded mining and processing facilities, and whose Office of Manufacturing and Energy Supply Chains hasfunded and overseen demonstration projects for rare earths and critical minerals mining and refining.
The LPO is in line for dramatic cuts, as Heatmap has reported. So, too, are other departments working on rare earths, including the Office of Manufacturing and Energy Supply Chains. In its zeal to slash the federal government, the Trump administration may have to start from scratch in its efforts to build up a rare earths supply chain.
The Department of Energy did not reply to a request for comment.
This vulnerability to China has been well known in Washington for years, including by the first Trump administration.
“Our dependence on one country, the People's Republic of China (China), for multiple critical minerals is particularly concerning,” then-President Trump said in a 2020 executive order declaring a “national emergency” to deal with “our Nation's undue reliance on critical minerals.” At around the same time, the Loan Programs Office issued guidance “stating a preference for projects related to critical mineral” for applicants for the office’s funding, noting that “80 percent of its rare earth elements directly from China.” Using the Defense Production Act, the Trump administration also issued a grant to the company operating America's sole rare earth mine, MP Materials, to help fund a processing facility at the site of its California mine.
The Biden administration’s work on rare earths and critical minerals was almost entirely consistent with its predecessor’s, just at a greater scale and more focused on energy. About a month after taking office, President Bidenissued an executive order calling for, among other things, a Defense Department report “identifying risks in the supply chain for critical minerals and other identified strategic materials, including rare earth elements.”
Then as part of the Inflation Reduction Act in 2022, the Biden administration increased funding for LPO, which supported a number of critical minerals projects. It also funneled more money into MP Materials — including a $35 million contract from the Department of Defense in 2022 for the California project. In 2024, it awarded the company a competitive tax credit worth $58.5 million to help finance construction of its neodymium-iron-boron magnet factory in Texas. That facilitybegan commercial operation earlier this year.
The finished magnets will be bought by General Motors for its electric vehicles. But even operating at full capacity, it won’t be able to do much to replace China’s production. The MP Metals facility is projected to produce 1,000 tons of the magnets per year.China produced 138,000 tons of NdFeB magnets in 2018.
The Trump administration is not averse to direct financial support for mining and minerals projects, but they seem to want to do it a different way. Secretary of the Interior Doug Burgum has proposed using a sovereign wealth fund to invest in critical mineral mines. There is one big problem with that plan, however: the U.S. doesn’t have one (for the moment, at least).
“LPO can invest in mining projects now,” Jacquez told me. “Cutting 60% of their staff and the experts who work on this is not going to give certainty to the business community if they’re looking to invest in a mine that needs some government backstop.”
And while the fate of the Inflation Reduction Act remains very much in doubt, the subsidies it provided for electric vehicles, solar, and wind, along with domestic content requirements have been a major source of demand for critical minerals mining and refining projects in the United States.
“It’s not something we’re going to solve overnight,” Jacquez said. “But in the midst of a maximalist trade with China, it is something we will have to deal with on an overnight basis, unless and until there’s some kind of de-escalation or agreement.”
