US Chip Curbs Impact Samsung and SK Hynix Shares in China

New US Chip Export Restrictions

• ⏳ The new curbs will take effect 120 days after an official notice, potentially impacting a substantial portion of the companies' memory chip output.

Impact on South Korean Chip Giants

• ⚠️ Analysts estimate that approximately one-third of the memory chip output for Samsung and SK Hynix is based in China.
• 🏢 Previously, the companies relied on exemptions to sweeping US export controls, but the new policy prohibits upgrading or expanding operations in China.
• 📉 By midafternoon Monday, Samsung shares were down nearly 3%, and SK Hynix shares fell by about 5%.

Company Responses and Future Outlook

• 🗣️ Samsung declined to comment on the developments.
• 🤝 SK Hynix stated it would maintain close contact with Washington and Seoul to minimize the impact of the policy change.
• 🏠 Analysts suggest the firms might limit short-term effects, as both companies have primarily planned new production line development in their home countries while maintaining existing China operations.
