Bank branch deposit competitiveness and deposit growth: Granular data and a new measure of competitiveness

We investigate the relationship between deposit growth and branch deposit competitiveness. We introduce a new measure of competitiveness focused at the branch level that utilizes granular product data. We find more competitive branches have higher rates of deposit growth that vary across product types and local market structures. The new measure of competitiveness at the branch level is intended to complement existing bank and market-level measures of competition and opens up a number of new opportunities for banking research and policy investigation.
