Basically most of the Western banking laws have just been recently changed to accommodate "bail-in" solutions instead of govt. rescues.
Read your banking fine print and you may have to go to govt. legal scholars to get the exact state of play such is the thicket that has been created. There are all kinds of considerations like secured note debt holders, unsecured notes, convertible notes, preferential debt obligations, etc, etc ... what it means is that bank depositors have now been placed at the end of a very long queue of people with their hand out when a banking collapse comes along.
Rule of thumb, as a depositor you should now view any money deposited in the bank as belonging to the bank, you do NOT have ownership, or possession, of that money any longer.
