South Korea Daily Briefing

Korean banks sold off sharply, with Woori Financial (WF) down 4.12% to $66.32, Shinhan Group (SHG) -2.62% to $66.13, and KB Financial -1.72% to $114.54. The move likely reflects BoK rate-hold positioning: markets are pricing a longer plateau at 3.50% after recent inflation data came in above 3.0%, which compresses bank NIM expansion expectations. The chaebol governance discount also remains a structural headwind — Korean financial conglomerates trade at 0.5-0.7x book versus their Japanese peers at 1.0-1.2x post-TSE reforms.

The 1.54% gain in EWY masks significant breadth weakness underneath. The KOSDAQ — where K-battery names (LG Energy, Samsung SDI, SK On) and smaller tech firms trade — was under pressure while KOSPI's top-heavy Samsung Electronics weighting supported the headline index. This divergence is the classic Korean market tell: when global semis are bid (likely driven by overnight Nasdaq moves) and domestics are soft, the ETF looks better than the experience of investors holding mid/small names. HBM cycle watchers will focus on SK Hynix's delivery cadence for NVIDIA's H200/H300 GPU builds.

Korea Electric Power (KEP) fell 1.40% alongside the broader Industrials sector, as global oil prices bouncing to 5-month highs (per Business Times SG) create cost pressure for Korea's energy-import-dependent utility sector. KEP's government-controlled tariff structure means it absorbs fuel cost spikes without immediate pass-through — which compresses operating margins in a rising-oil environment. This is a stock-specific headwind that could prompt another quarterly loss disclosure when Q3 numbers arrive.
