I stand corrected <blush>.
Most likely the process is seamless, and if you write a check that gets delayed, you did so in good faith and only an ogre would give you grief about it.
Well, FWIW, there was some verbiage on another page about some program last fall that was for "unlimited" coverage for non-interest bearing checking and savings which required an opt-out from each institution. My reading of it is that this was to protect folks who had inadvertently gone over the $100,000 limit, but the bank opting out would mean the limit was still in force. So either way my small account is still okay. The new legislation does not supercede this program - so if the institution has not opted out, some accounts might still have the unlimited coverage, else the limit is now $250,000.
Perhaps this was the program you were thinking about. The wording is not straightforward, so it would be easy to think that some checking and saving accounts are not covered at all, rather than covered to the max.
Personally, I can't imagine having that much money in an account that was not interest bearing. Well actually, these days I have a hard time imagining having that much money... period.
So, thanks for the heads up. Made me do a little work, but hey - serendipity. Now I know where to find out what to do next with my account, sometime in the next few days, after the data is available on the fdic site.
