Korea Chip ETFs Fall 3% as Trump-Xi Summit Threatens Samsung, SK Hynix

Aju Press2 min read6 sources

Why are Korea semiconductor ETFs falling?

Korea chip ETFs (KCHP, KSMH) dropped 3% to around $24 Friday as markets priced in a US-China chip-equipment deal threatening Samsung and SK Hynix China fabs ahead of the September 24 summit.

Key numbers

KCHP 1-day move-3.08%to $24.62 on Sep 19, fourth day of trading
KSMH since launch-6.97%since Aug 19 inception
EWY 1-month decline-19.5%from June 2026 peak to Sep 2
SK Hynix China DRAM share~40%of total DRAM output from Wuxi plant
Samsung China NAND share~35%of total NAND output from Xi'an plant
China rare earth processing shareup to 90%of global capacity; moratorium expires Nov 10

What happened

Korea chip ETFs (KCHP, KSMH) dropped 3% to around $24 Friday as markets priced in a US-China chip-equipment deal threatening Samsung and SK Hynix China fabs ahead of the September 24 summit. Xi Jinping's first White House visit in 11 years may produce a deal swapping US chipmaking equipment access to China for Beijing extending a moratorium on rare earth export controls that expires November 10. Samsung makes about 35% of its NAND flash memory at its Xi'an, China plant; SK Hynix makes about 40% of its DRAM chips at Wuxi — both face costly disruptions if equipment rules shift. China controls up to 90% of global rare earth processing capacity.

Why it matters

Korea chip ETFs and the companies they track — Samsung and SK Hynix — are caught between two governments that each control something the other side needs. If Washington eases chipmaking equipment rules for China, it could erase the technology edge Samsung and SK Hynix built under years of US restrictions. And if China lets its rare earth moratorium expire on November 10, materials essential to chips, EVs, and defense hardware could become scarce worldwide.

How we got here

  1. Busan Summit: US-China truce pauses China rare earth controls to Nov 10, 2026.

  2. Samsung, SK Hynix lose automatic US equipment approvals for China fabs.

  3. KOSPI hits record high; SK Hynix briefly overtakes Samsung in market value.

  4. Korea chip stocks sell off; EWY falls nearly 20% over the following six weeks.

  5. Trump-Xi summit at White House; chip equipment-for-rare-earth deal expected.
