Please link to the policy where the FDIC announced 100% coverage of all deposits in all banks, not the press release where they announced providing depositors coverage in two specific banks.
Edit: this is not debating nuances. Insurance coverage is not what we feel and think it is. It's what is specifically documented and funded. In this case, the FDIC is neither documenting nor funding 100% coverage for all deposits in the nation. They may decide to do so, but they certainly have not at this time.
