Timothy Geithner's exit interview

A: Your predecessor Hank Paulson in his book describes how at the height of the crisis he would have sleepless nights, worrying that a giant financial collapse was going to occur on his watch and that he would go down in history as the Herbert Hoover of the current era. Your colleagues all say you are remarkably calm, even in the middle of a crisis.
TG: Well I was very worried throughout that period of time. Starting in August of 07 I had moments of deep, serious concern about the future. The hardest part for me was that period between when we knew we faced an existential threat of collapse but before we figured out what we were going to be able to do. Before we figured out the contours of our plan.
LA: Was that from Lehman onwards?
TG: I would say from the end of December of 07, there was a great sense of foreboding, gathering storm, forces beyond our control. Even as early as back in August of 07. But it dramatically worsened in the fall of 08, of course.
