Global Supply Chain Under Pressure From Dual Mega-Trends

The increasing demand for rare earth elements, driven by artificial intelligence infrastructure and defense spending, is putting pressure on global supply chains. Neodymium and praseodymium, used in high-efficiency magnets, are in high demand, but China’s control of 87% of global refining infrastructure poses a significant challenge. The US and other nations are investing in domestic supply chain resilience, but the 16-year timeline for new projects to come online may not meet current demand pressures, as reported by Unknown Source.
