What happened that day?

  • The Nasdaq rose 2.71% on the day
  • The Fed cut its policy rate by half a point at once. The market had expected half that
  • It was the first cut in four years, reversing a direction that had only gone up for more than two
  • The message mattered more than the size. Cutting large says the situation is judged serious, and also that they will not stand back
  • The cut carried the Nasdaq into late October and its last high before the crisis
  • But lower rates did not fix banks refusing to lend to each other. That was a problem of trust, not of price
