A Moebs $ervices Study on Checking Account Types & Features found that credit unions in comparison to other depository institutions tend to offer a single checking account option to consumers.
The study noted that 11.4 percent of all depository institutions offer just one type of checking account.
Among financial institutions that offer a single checking account option, 71 percent were credit unions.
The top reason cited by credit unions for offering a single checking account was "to keep servicing costs to a minimum." In addition, many credit unions with less than $100 million in assets "cannot justify the cost of 2 or more checking accounts."
