What happened that day?

  • 28 June 2002 — the Nikkei 225 rose 3.51% to close at 10,621.84. No single cause can be pinned to the day
  • Two sessions earlier Tokyo had fallen hard on news of accounting fraud at a large American telecom. This was the second day of taking it back
  • Why that news reached Tokyo is simple: if American corporate numbers cannot be trusted, neither can the outlook for American demand
  • Japanese exports stood on that demand, so an American accounting problem became a Japanese earnings problem
  • It was also the last trading day of the first quarter of Japan's fiscal year, which stacks book-tidying trades onto the same session
  • From late May to 10 October the index fell 29.55% over this episode
  • Tokyo's own bottom came later still, in November
