- In this study, we explored some of the important community linkages of municipal bank deposits. The results provide insight into bank community involvement and services to municipal customers. Also, estimates of the loss of credit and the economic impact of the loss of municipal bank deposits are presented. These multiple factors need to be assessed in combination with any prospective increases in interest revenue for New York's municipalities. A comparison is made with the potential need for state programs to elicit capital to replace the potential investment lost to rural communities if municipal bank deposits were lost through other investment options.
