China's Ministry of Commerce announced dramatic expansion of rare earths export restrictions on October 9, 2025, adding five new elements and extending controls to 14-nanometer and more advanced semiconductors, memory chips (256+ layers), chipmaking equipment, and AI research with military applications. The move follows similar April restrictions and U.S. calls for broader chipmaking equipment bans ahead of Trump-Xi talks. For financial institutions, this signals sustained structural volatility in semiconductor supply chains and potential margin pressure on AI chipset producers dependent on Chinese materials or processing.
