Determinants of customer loyalty: a study with customers of a Brazilian bank

The purpose of this paper is to analyze customer loyalty in the context of existing relationships between Brazilian banking service provider and its customers in the context of B2C (Business-to-Consumer) relationships. Hence, a theoretical model was proposed and tested with banking services private individual customers taking into account perceived value, service provider reputation, financial bonding tactics, structural bonding tactics, social bonding tactics and switching costs as customer loyalty determinants.

A multivariate statistical approach with structural equations modeling was used in a 505 customer sample of the one prominent bank in Brazil.

Results indicate that the proposed theoretical model confirming a satisfactory fit, presenting a good explanatory power (R²=0.738) and supporting that perceived value influences the service provider reputation; financial bonding tactics, structural bonding tactics and social bonding tactics influence perceived value; service provider reputation influences switching costs; switching costs influence customer loyalty and the social bonding tactics influence customer loyalty.

The results evidenced in the present research could serve as benchmarking for other researchers or managers connected to the financial service sector (or bank service) when looking for a better understanding about the antecedents of customer loyalty, adapting strategies and actions to stimulate and generate better market and economic–financial results for the institutions of this sector.

Finding out which constructs better explain customer loyalty, and its possible relations, is something relevant for the banking sector, once it can generate more effective managerial insights, positively making an impact in a customer portfolio performance, or the financial institution itself, from the construction, maintenance and strengthening of the relationships with customers.
