The move also marked the stock's biggest intraday percentage gain since October 24, 2023. "Lynas' rally ... is a powerful reflection of the dual drivers at play today: escalating geopolitical tensions and surging demand for green technology," said Hebe Chen, market analyst at Vantage Markets. "As China tightens rare-earth export controls, markets are pricing in supply risks — positioning Lynas ... as a strategic hedge." China, which accounts for about 90% of global rare-earth production, imposed export restrictions in April on the strategic minerals in response to tariffs introduced by US President Donald Trump. The move raised alarms across industries reliant on the 17 rare-earth elements, which are critical for defense systems, electric vehicles, clean energy, and advanced electronics.
