Trouble is if those investments lose money then it could be the start of a downward spiral, where the sum of their available cash and unrealised investments is less than the sum of the customer's balances. In other words, they can't pay out everyone. A run on the bank (where a large number of customers withdraw all their money) could leave the remaining customers with cents in the dollar, or nothing.
