Depends. As I’ve stated here before, there are two things that kill a bank: concentration and leverage (which eventually lead to death via lack of liquidity). The biggest banks are being killed by both (but mainly leverage). The small banks that are failing thus far are entirely the result of insanely high concentrations in construction and development. I think we’re in for 300-500 FDIC-insured failures, so we’re really just getting started. But, personally, I don’t expect to have any involvement with any of these. Recall that this number represents 4%-6% of the total bank and thrift charters out there. Regarding “worry,” well, where you stand depends upon where you sit. I’m concerned about the overall economy (that’s an understatement), but I’m not particularly concerned about my personal economy, which is the only one I have much control over. I can’t speak for your personal economy, though.
