- Lynas shares were last quoted at A$17.95, down 9.8% from A$19.90 on May 13.
- The U.S. and China are weighing a rare-earth truce extension, but Chinese shipments of some heavy rare earths remain down about 50% since controls began in April 2025.
- Polymarket showed a 53% chance of a U.S.-China tariff agreement by May 31, a thin but timely read on how traders see the talks.
Lynas Rare Earths Limited shares fell 9.8% on Thursday, cutting into one of the strongest rallies on the Australian market as investors reassessed how much of the stock’s value rests on China supply risk and the premium for non-Chinese rare earths. The stock was last shown at A$17.95, compared with a May 13 close of A$19.90.
The timing matters. Lynas is the world’s largest producer of rare earths outside China, and rare earths are used in products from electric vehicles and chips to defence equipment. That makes the company a direct market proxy for supply-chain fear when Beijing and Washington argue over critical minerals.
Reuters reported this week that the U.S. and China were considering extending a truce on Chinese rare-earth export curbs at a leaders’ summit, even as Chinese customs data showed shipments of yttrium, dysprosium and terbium still down about 50% since controls were imposed in April 2025. Dysprosium and terbium are heavy rare earths used to strengthen magnets, including those used in electronics, cars and defence systems.
That is the trade investors were marking down. The Bull, an Australian market site, said Lynas fell without specific company news, while Lynas’ own announcements page listed its April 20 quarterly activities report as the latest major ASX filing.
Lynas has not lacked operating momentum. The company reported gross sales revenue of A$265 million for the quarter ended March 31, more than double a year earlier, and total rare earth oxide production of 3,233 metric tons, up more than 69%. It also said customers had a “renewed and urgent focus” on securing supply chains outside China. Reuters
Chief Executive Amanda Lacaze said last week that U.S. and European rules were already leading to “changed purchasing decisions” by customers seeking compliant supply outside China. She also called for governments beyond the U.S. and Japan to use floor prices to support non-Chinese supply. Reuters
Analysts tracking the physical market remain wary of any easy read from headline export data. Ilya Epikhin, senior principal at Arthur D. Little, told Reuters that “headline export volumes can be misleading,” while Project Blue research director David Merriman said the situation “looks set to get worse before getting any better.” Reuters
Prediction markets showed no clean consensus on a broader thaw. A Polymarket contract on whether the U.S. and China would reach a tariff agreement by May 31 showed a 53% implied probability, with about $48,100 in volume; the contract is not a rare-earth-specific market, but it gives a rough gauge of how traders are pricing the summit’s trade risk.
Competition is also moving. U.S. peer MP Materials said it produced a record 917 metric tons of neodymium-praseodymium, or NdPr, in the first quarter, up 63% from a year earlier, and sold a record 1,006 metric tons. NdPr is used in high-strength permanent magnets, a core product area for both Lynas and its rivals.
The risk for Lynas is two-sided. If the Trump-Xi talks produce a durable easing of China’s curbs, some of the scarcity premium in non-Chinese rare-earth equities could fade quickly; if curbs remain tight, customers may keep paying for alternative supply. Lynas also still has regulatory exposure in Malaysia, where its licence was renewed for 10 years but with a requirement to stop producing radioactive waste by 2031 and a five-year review that could affect operations if conditions are breached.
Even after Thursday’s fall, the stock remains far above where it began the year, with market data showing Lynas up about 60% in 2026. The selloff, for now, looks less like a break in the company story than a test of how much investors are willing to pay for rare-earth security before the geopolitics are settled.
