Data files on 407 banks, between the dates of 2007 to 2009, on the daily borrowing with the US Federal Reserve bank. The data sets are available from Bloomberg at this address data
This is an unprecedented look into the day-to-day transactions of banks with the Feds during one of the worse and unusual times in US financial history. A time of weekend deals, large banks being summoned to sign contracts, and all around chaos. For the economist, technocrat, and R enthusiasts this is the opportunity of a life time to examine and analyze financial data normally held in the strictest of confidentiality. A good comparison would be taking all of the auto companies and getting their daily production, sales, and cost data for two years and sending it out to the world. Never has happened.
Thank you Bloomberg for making it available and Drudgereport.com for the link to it.
