True it’s only anecdotal evidence, but I’m pretty sure people search Google about FDIC insurance when they’re worried about their bank going bust.
What you see on this chart is a bank run precursor, the starting gun getting cocked. All someone has to do now is blink and the run is on. Doesn’t matter if it’s a false start or not once a run starts, the outcome becomes inevitable.
Note, there are solutions to this problem, as discussed by Roubini. It starts with the government increasing FDIC insurance immediately (a temporary increase to $250,000 FDIC insurance was signed into law on Friday) and also recapitalizing banks (more than buying bad assets).
