Depositors lent their money to the bank. They took a risk by trusting a bank to manage their money for them. The bank took their money, invested it and lost it all.
It didn’t lose it all. About 90% is still there as assets and is being sold as we speak. The liquid assets have been sold already, so 50% will go back to the depositors next week.
Of course but the point still stands. If it lost it all we’d all be in serious trouble. It lost ~10% and there’s a nonzero chance depositors will be made whole anyway (with zero taxpayer money involved).
Let them lose too.
