South Korea industrial output jumps most in 15 years on chips

· Economy · South Korea

South Korea's industrial output expanded in September at its fastest pace in 15 years, driven by semiconductors, Yonhap reported, citing official data. Retail sales and facility investment also rose during the month. Separately, foreign investors again turned net sellers of Korean stocks in September, the data showed. The figures underscore how strongly chip exports, boosted by the global AI build-out and soaring memory prices, are supporting Asia's fourth-largest economy even as domestic demand and equity flows remain uneven. Korean newspapers meanwhile warned that headline national wealth can rise while households feel poorer.

Why it matters：Korea's chip-led rebound is a leading indicator for the global memory and AI hardware cycle, and its uneven spillover into domestic demand mirrors a pattern across export-led economies.

Key points

  • Industrial output grew at a 15-year high in September.
  • Retail sales and facility investment also increased.
  • Foreign investors returned to net selling of Korean stocks in September.
