A sweep account links your commercial checking account with an interest-bearing money market account. Your checking account balance is kept at a pre-determined level by transferring funds to or from your money market account. At the end of each business day, we "sweep" your checking account, placing funds into the money market to earn interest overnight. At the start of the next business day, your funds sweep back in to your checking account. All of this activity is done automatically, for a small monthly service charge. You can start a sweep account with us for just $1.
