I don’t think you can really fault the FDIC on this, it’s purely Washington’s doing. And that would be under both parties (I’m pretty sure the coverage change had broad support so you can’t blame either party) under the Bush administration. The immediate change of protecting deposits up to $250,000 from $100,000 would have caused an excessive draw on the FDIC funds. As well, the premiums they’ve received over the past few years would have been based on $100K coverage, not $250K.
My recommendation would be to have them borrow directly from Washington, it was their policy decision, let them sort it out.
