In our recent staff report, we size up this channel by studying how U.S. banks, large and small, fared against disasters past. We find even the most destructive disasters had insignificant or small effects on bank stability and small and positive effects on bank income. We conjecture that recovery lending after disasters helps stabilize larger banks while smaller, local banks’ knowledge of “unmarked” (flood) hazards may help them navigate disaster risk. Federal disaster aid seems not to act as a bank stabilizer.
