Frankfurt, July 16, 2026

Asian stock markets were mostly down significantly on Thursday, driven by a broad sell-off in chip stocks, which caused the South Korean KOSPI to temporarily plunge more than six percent and also pulled the Japanese Nikkei deep into negative territory.

A broad sell-off in chip stocks sent stock markets in East Asia into a downward spiral on Thursday. In Seoul, Samsung Electronics and SK hynix are plunging, with both stocks together accounting for half of the KOSPI's weighting. The South Korean benchmark index temporarily crashed 6.41 percent to 6,817.72 points; trading in Seoul was temporarily halted due to excessive price swings, as has frequently been the case in recent weeks. In addition, the Bank of Korea has raised interest rates for the first time in three and a half years, with the key rate now at 2.75 percent following a 25 basis point move expected by market participants.
