What happened that day?

  • The Nasdaq fell 5.22% on the day
  • It emerged that a European bank had borrowed dollars from the European Central Bank, meaning it could not get them in the market
  • European banks took deposits in euros and lent in dollars. If dollars cannot be found, assets have to be sold
  • This is exactly the mechanism that broke in 2008. The problem was maturity, not price
  • US data was weak the same day and European bond yields rose again
  • The slide ran into early October, ending when the ECB opened long-term lending to banks
