What happened that day?

  • On 20 November 2008 the S&P 500 fell 6.71% in a single day
  • The index fell to its lowest level of the crisis so far. The final low would come the following March
  • US carmakers had said they were out of cash and asked for government help, and Congress was leaning toward refusing
  • Cars are built on tens of thousands of supplier firms, so one failure stops manufacturing in a chain
  • An argument broke out over why banks got public money and manufacturers should not, and the decision was postponed
  • In December the government did provide emergency funding and the worst was avoided. The index low still came in March 2009
