What happened that day?

  • On 7 April 2025 the KOSPI fell 5.57% in a single day
  • It came right after the US announced broad tariffs across trading partners
  • Korea depends heavily on exports and the US is a major market, so the impact was direct
  • Cars and semiconductors, with their large US shares, fell hardest
  • Tariffs on China also shook the structure where Korea sells components into Chinese manufacturing
  • A tariff pause days later produced the rebound
