There is a very valuable reference article, " The New York Fed's timelines of policy responses to the global financial crisis" by Rebecca Hellerstein, William Ryan and Jeffrey Shrader out on July 14, 2009. Read the entire story here.
The article has detailed tables covering:
* Fed policy actions
* Market events
* Other policy actions (U.S.)
* International bank liability guarantees
* International liquidity and rescue interventions
* Other market interventions
Hat tip to Barry Ritholtz (The Big Picture) here.
