geopolitical risk

Geopolitical risk in semiconductors refers to the impact of trade policies, export controls, national security concerns, and regional conflicts on the global semiconductor supply chain and technology access. Key geopolitical tensions: (1) US-China technology competition—export controls on advanced chip technology, equipment, and talent; (2) Taiwan risk—TSMC produces ~90% of advanced logic, Taiwan Strait stability critical; (3) Russia/Ukraine—neon gas supply disruption (used in lithography lasers); (4) Japan-Korea—2019 trade dispute affected photoresist and HF supply. US export controls: (1) Entity List—restrict sales to specific Chinese companies (Huawei, SMIC); (2) Equipment controls—ban export of advanced lithography (EUV), etch, deposition to China; (3) Technology thresholds—limit chip performance (computing power, bandwidth) exportable to China; (4) Foreign direct product rule—extraterritorial application to non-US companies using US technology. China response: massive domestic investment ($150B+ Big Fund), develop domestic equipment and EDA tools, stockpile inventory, focus on mature nodes where restrictions are fewer. Industry impact: (1) Supply chain bifurcation—separate US-allied and China ecosystems emerging; (2) Redundant investment—duplicate fabs in multiple regions; (3) Increased cost—regionalization less efficient than optimized global supply chain; (4) Innovation risk—restricted collaboration may slow progress. Regionalization efforts: US CHIPS Act ($52B), EU Chips Act (€43B), Japan ($13B+), India ($10B+), Korea K-Chips Act. Strategic implications: semiconductor technology increasingly viewed as national security asset, not just commercial product. Companies must navigate complex compliance requirements while maintaining global operations.
