This chapter analyzes the retail banking behavior in Portugal for the period between 2008 and 2010. The data collection took place through the accounting consultation of the reports and accounts of the years under analysis. The selected variables reflect the strategic actions of retail banking during the period under analysis, and it can be argued that retail banking in Portugal has clear differences among players over time. In particular, banking institutions have different competitive strategies, the strategic groups do not have similar resources, and strategies also differ between strategic groups. This reflects the competitive structure of the national retail banking industry.
