What happened that day?

  • The Tōhoku earthquake struck on 11 March, the reactor crisis followed, and the index crashed over two sessions
  • Factories stopped and power supply was cut, so disruption across manufacturing looked unavoidable
  • The Bank of Japan injected a record amount of funds and increased its equity ETF purchases
  • The rebound began as views spread that the reactor situation would not reach the worst case
  • Days later the major countries intervened together in the currency market to stop the yen surging
