The big impact will be on businesses. They will be the ones most likely to have more than 100K on deposit. Regular people who have 100K are more likely to have it invested.
The net effect on businesses will be to leave much less money in the bank, and work off a line of credit so that their net balance stays close to zero or slightly negative.
I'm going to guess that the bond holders had more "pull" with the EU bureaucrats than common depositors did.
The bondholders were largely Germans, and Germany controls he Eurozone.
