Banks are selling owned portfolio properties or letting leases lapse to setup in retail strip mall or other buildings to decrease size/costs due to more digital options and less foot traffic. This is not new, only excellerated by the lockdowns...

I would not waste time on how many or where banks are... see if assests under management change. That is the only way to determine if a bank is actually hurting. Less assets, less lending to charge interest. Deposit accounts are important to maintain and offer lending... no ability to create new debt, means no money.

A lot of consolidation and acquisitions have taken place which is different than going under. It just means assests under management become more concentrated by the larger or growing institutions...
