AI动荡令美元强势受抑 · 外汇每日快照
Core conclusion · Tlines extraction
The dollar gave back gains made after a stronger-than-expected September US CPI, with the index falling from a year-to-date high of 102.95 toward 102.00. The 2-year Treasury yield jumped about 18bps to 4.95% post-CPI before retreating to near 4.70%. MUFG attributes the reversal mainly to an unwind of AI-related trades driving risk-off conditions, most visibly a near 9% Kospi fall, extending its decline from the June peak to just over 40%.

Key arguments

- South Korean equities led the sell-off, with Kospi down almost 9% and chipmakers SK Hynix and Samsung each down around 12%.
