SK Hynix keeps US and Japan expansion options open despite KRW40T capex plan

SK Hynix’s KRW40T capex plan signals a decisive shift in global memory supply chains, driven by AI demand. This move accelerates upstream advancements in EUV lithography, high-k dielectrics, and advanced packaging, while pressuring downstream AI chipmakers to integrate memory and compute more tightly. However, its cautious stance on U.S. and Japanese investments reflects strategic risk management amid tightening tech export controls. Should U.S. restrictions on China intensify, SK may pivot to Southeast Asia or China Taiwan/ Taiwan, China to secure supply chain resilience. Competitors like Micron and Infineon may respond with accelerated Asian expansions to capture market share. Over the next 12–24 months, the global memory sector will be shaped by a convergence of technological innovation and geopolitical dynamics, with SK’s adaptive strategy likely setting the tone for industry evolution.
