What happened that day?

  • On 6 August 2024 the Nikkei 225 rose 10.23% in a single day
  • The day before, 5 August, had been one of the worst falls in the index's history
  • It started with a Bank of Japan rate rise. Enormous positions had built up borrowing cheap yen to buy assets elsewhere — the carry trade
  • When the yen suddenly strengthened, repaying those borrowed yen got expensive, and investors sold assets to buy yen back all at once
  • As the unwinding ran its course the market snapped back the next day. It helped that the BOJ said it would not raise rates further while markets were unstable
  • After two days of falling hard and rising hard, the index ended up close to where it started
