📉 MSCI Korea Drops 3.9% Across All Sectors Despite OECD Growth Upgrade to 3.7%
Korean equities saw one of Asia's sharpest declines Wednesday, with iShares MSCI Korea falling 3.85% to 185.20. The selloff was broad-based — zero gainers among tracked names. Industrials led losses at -3.72% (KEPCO KEP -3.72%), followed by Tech/Semiconductors at -2.96% (LPL -2.96%) and Banks at -2.78% (KB Financial -2.72%). The decline came despite OECD raising Korea's 2026 GDP growth forecast from 2.6% to 3.7%, suggesting global risk-off flows overwhelmed the macro upgrade. KOSPI and KOSDAQ proxies both under pressure as Samsung and SK Hynix HBM demand outlook awaits clarity.
With no gainers among tracked Korean ADRs, the selloff hit Industrials (-3.72%), Tech/Semi (-2.96%) and Banks (-2.78%) equally. KEPCO (-3.72%) and LPL (-2.96%) led sector drops. The breadth of the decline suggests global risk-off positioning rather than Korea-specific fundamentals.

For SK Hynix and Samsung, the key question is whether HBM demand accelerates alongside model proliferation or whether cheaper model architectures reduce per-unit memory intensity.

The divergence between the OECD growth upgrade (+1.1pp to 3.7%) and the -3.85% equity move is a signal that global risk-off is dominating. Watch SK Hynix and Samsung pre-market Thursday — HBM order visibility from Nvidia's next earnings will reset the semi sector view. BoK rate decision timing is the domestic catalyst.
