Bank stocks will crash more, and consumers will ultimately feel the pinch as banks use the only tools then available to create margins: dramatically increased fees and cost of borrowing.
But to say that the FDIC came out and announced 100% protection of all deposits is no more true today than it was when banks were bailed out in the '08 crisis, and there have been many, many examples of depositors losing money since those bailouts happened.
You can debate the nuances all you want, I’m sticking with the simple proof and reality. FDIC member banks offer 100% depositor protection now.
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.
