"Money that is deposited into a checking or savings account is considered an “unsecured debt” of the bank. Thus, before a bank becomes insolvent, the European regulators can simply require the bank to confiscate its customer’s deposited money and convert it to shares of equity that have the potential to become worthless on the market or be tied up for years in resolution proceedings. The result is that the distressed bank’s customers may very well become the largest class of unsecured creditors of the distressed bank, or worse, the largest class of shareholders of the distressed bank. Unsecured creditors and shareholders are the next to last and last, respectively, parties to be paid in bankruptcy or liquidation proceedings."

"Your status is that of A CREDITOR TO THE BANK and the BANK IS IN LAW A DEBTOR to you. You are deemed to have “lent” your money to the bank for the bank to apply to its banking business (even to gamble in the biggest casino in the world – the global derivatives casino).
You have become a creditor, AN UNSECURED CREDITOR."
