Our operations department is wanting to change our system in order to allow negative balances on savings accounts. The premise for this is to collect all of the fees that a customer owes on small balance accounts.
For example, a customer has $5 in their account and they are due to be charged a $10 fee. Currently , we only take the $5 that is available. Under the proposed idea, we would allow the balance to go to -$5 and then collect that amount from the customer. We would only allow this on fees that we charge on the accounts (and that were properly disclosed), we would not allow an ACH item or in person withdrawal to cause this to happen. (Some holes exist that allow ATM withdrawals to cause an overdraft currently.)
My question is "Is this permissible"? Is there any guidance to this that I can find? Will I need to change disclosures to properly indicate that this is a possibility?
Thanks for any advice.
