What happened that day?

  • On 5 February 2008 the S&P 500 fell 3.2%
  • A services sector reading that morning fell sharply. Services are far larger than manufacturing, so it landed hard
  • At the same time there was talk that bond insurers might be downgraded
  • Those firms had guaranteed bad debt. If the guarantee failed, the losses at the banks holding it grew again
  • From here the structure of the crisis — spreading from one place to the next — became clear
  • No single trigger can be pinned to this day
  • In this stretch the index was 18.64% below its peak
