South Korea Daily Briefing

Warsh's installation as Fed chair with an apparent rate hike bias (per Fed minutes) forces the Bank of Korea into a difficult position. BoK has been holding Selic-equivalent base rate stable, watching inflation trends and KOSPI sensitivity. If the Fed moves to hike, BoK faces the classic EM dilemma: follow and risk domestic growth, or hold and accept KRW weakness. KRW/USD is the immediate transmission channel — watch for BoK statement or emergency language if KRW moves below 1,380 to the dollar on USD strength.

The semiconductor cycle is the cornerstone of KOSPI's 2026 thesis, and Warsh's rate stance is now the key external variable. Samsung Electronics' HBM3E ramp for NVIDIA and SK Hynix's DRAM bit-growth guidance both depend on continued AI capex from US hyperscalers (Microsoft, Google, Amazon). If Warsh hikes, the cost of capital for hyperscaler capex rises — which could slow the AI infrastructure build that is driving HBM demand. The Korea Tech/Semis sector's implied activity today suggests near-term investor focus remains bullish on the HBM cycle, but the Warsh risk premium is building.

Trump's statement that he wants Warsh to be 'completely independent' after years of Fed pressure for rate cuts is being read by Korean markets as a signal that political rate-cut expectations are fading. For Korea, this matters because the rate-cut narrative had been supporting multiple expansion across KOSPI growth names (batteries, biotech, platform tech). A higher-for-longer Fed removes that tailwind. K-battery names (LG Energy, Samsung SDI, SK On) are particularly exposed — their capex cycles were financed assuming falling cost of capital.
