Enhanced demand deposit accounts

摘要

A method for adjusting a demand deposit account. The method may comprise the step of structuring the demand deposit account with at least a first balance tier and a second balance tier. The methods may also comprise the steps of monitoring a balance of the demand deposit account, and accruing interest to at least a portion of the balance of the demand deposit account at an interest rate if the balance falls within the second balance tier. The interest rate may be tied to an interest rate of an investment account.
