What happened that day?

  • On 9 August 2007 the S&P 500 fell 2.96%
  • BNP Paribas froze withdrawals from three of its funds — funds holding US mortgage debt
  • The reason was the alarming part. The bank said it could not put a price on them, because the buyers had disappeared
  • Banks began doubting each other. Nobody knew who held how much, so even overnight lending dried up
  • The European Central Bank pushed emergency cash into the system that same day, on a scale it normally never uses
  • Many date the credit crunch from here. Lehman Brothers followed a year later
  • From the July peak the index was down 9.43% before it turned
