Expert Reveals China’s Rare Earth Chokehold: ‘Within 6 Weeks, American Industry Was Struggling’

A guest on the TechSurge Deep Tech Podcast reframed the rare earth debate in stark terms this week, arguing that Washington’s supply chain panic misses the actual problem. The headline numbers are jarring: “For heavy rare earths, China processes 99% of them.” When Beijing tightened export controls, the timeline to industrial pain was measured in weeks, not quarters.

“When China turned off the taps, within six weeks, American industry was struggling,” the guest said. That fragility is compounded by a stockpile that has been hollowed out. “In 1990, we had $25 billion of materials in our national defense stockpile. Last year, we had $900 million,” a collapse of roughly 96% in strategic reserves over three decades.

The Reframe: An Economics Problem Wearing Geopolitical Clothes

The most provocative claim from the segment was diagnostic. “The biggest misconception is it is a geopolitical problem. It is actually an economic problem,” the guest argued, adding that “making mining profitable is the biggest challenge that we have.”

The macro data backs that up. Bureau of Economic Analysis figures show U.S. mining value-added shrank from $411.1B in Q1 2025 to $370.9B in Q4 2025, with mining’s share of GDP compressing to just 1%. Q2 2025 alone posted a -9% growth rate, the sharpest contraction in the sector’s recent history. Capital does not flow toward businesses with persistently negative growth, and the U.S. trade deficit running at -$60.3B as of March 2026 reflects that import dependency.

What the Market Is Already Pricing In

MP Materials (NYSE:MP), the closest thing the U.S. has to a domestic rare earth flagship, has become the cleanest read on investor sentiment toward this thesis.

Shares are up 194% over the past year and 44% year to date, with a 42% surge in the past month alone. The market cap sits near $12.1 billion against trailing revenue of just $275.5 million, a price-to-sales ratio of 43.9 that prices in years of policy tailwinds. EBITDA remains negative $36.2 million and EPS is -0.5, which is precisely the guest’s point: even the U.S. champion is not yet a profitable mining business. MP Materials’ investor materials detail the Mountain Pass operation and the Independence magnetics build-out in Texas.

What to Watch Next

Sprott just launched the Rare Earths Ex-China ETF (NYSEARCA:REXC), and pure-play developers like USA Rare Earth (NASDAQ:USAR) and Critical Metals (NASDAQ:CRML) are racing to build Western processing capacity. The investable question is whether subsidies, offtake agreements, and tax credits can durably alter mining unit economics. Until they do, the 6-week buckle remains the base case for the next disruption.
