South Korea Daily Briefing

Newsis reported semiconductor stocks collapsed with the won/dollar exchange rate spiking as risk-off positioning hit KOSPI. SK Hynix and Samsung — NVDA's dominant HBM memory partners — absorbed the full governance-risk discount as investors repriced NVDA supply-chain concentration risk. The key question: if NVDA's data-center GPU business faces disruption from the Jensen Huang investigation, HBM orders from Samsung and SK Hynix could slow. AMD's concurrent +13.26% session in the US provided a partial offset — AMD is also a major HBM customer and its blowout data-center revenue suggests alternative demand pull-through.

Newsis reported the National Pension Service (NPS) has accumulated ₩109T in domestic equity losses, with limited remaining firepower for contrarian buying. The significance: NPS has historically acted as a structural buyer during KOSPI selloffs, but constrained 'remaining ammunition' (남은 실탄) means the institutional stabiliser is weakened. This removes a key support mechanism during semiconductor-led selloffs and increases KOSPI's beta to global risk-off events.

Newsis covered Korean biotech firms advancing blood disease drug programs as the K-바이오 (K-Biotech) narrative gains momentum as a KOSPI diversification story away from semiconductor concentration. The biotech sector offers a rare non-semi, non-China-dependent growth narrative for KOSPI — particularly relevant on a day when semiconductor names were under heavy selling pressure.
