Answer:
Overdraft fees are required to be disclosed in writing under Regulation DD. You must advise your consumer customers of a fee change in writing, at least 30 days before it goes into effect. It can be on a statement, a statement stuffer or in a separate mailing. It can be delivered electronically if you and the customer have "done the E-SIGN dance" and you have the customer's demonstrable consent to electronic notification. A banner notice on your online banking site would be the equivalent of posting a notice in your customer lobby. It won't satisfy the regulatory disclosure requirement.
