South Korean and Japanese equities plunged after a sudden reversal in global AI sentiment and macro developments. In Seoul, Samsung Electronics fell 7.4% and SK Hynix dropped 10.1% intraday; the two memory-chip makers account for roughly half of KOSPI market capitalization. KOSPI slid more than 9% intraday and triggered a 20-minute trading halt — the fourth such pause this year. In Tokyo, the Nikkei 225 fell over 3%, led by SoftBank and Kioxia, down about 10% and 14% respectively.
