Why KOSPI 200 (KR200) fell 3.00%
KOSPI 200 (KR200) fell 3.00% on October 8, 2026 — Inflation worries drive Seoul shares lower.
What happened
The KOSPI 200 fell 3% after opening higher, as Seoul shares turned lower on inflation worries and rising bond yields.
Why it moved
Higher inflation expectations push the market to price in tighter policy for longer, which compresses equity valuations and makes bonds more attractive relative to stocks.
Why it matters
The Korean market's AI-chip rally in Korea Tech is being tested by a macro backdrop where rates and inflation matter more for the index.
What would break the thesis
Cooler inflation data or a policy signal from the central bank that leans softer would relieve the pressure on yields and multiples.
