The FDIC insures bank deposits up to a limit. The limit was $100000 for many years but was recently raised (supposedly temporarily until 12/31/2009) to $250000 due to the current financial crisis. The limit is per depositor per bank. However there is a loop hole involving revocable trust accounts which allows you to increase the limit several fold. In view of the current situation this seems like a good thing to do if you are over the limit. However I think it is questionable public policy to allow the limit to be increased in this way. It gives an undue benefit to paying attention. And setting up and maintaining the trust accounts imposes unproductive overhead costs on the economy.
