This report gives an overview of the major regulatory relief provisions in H.R. 3505 and S. 2856, focusing on their potential impact on bank concentration. The report examines both bills’ provisions to assess whether they are likely to support or discourage bank consolidation. The consolidation of the banking industry arguably reduces competition, which could tend to raise the price of banking services. On the other hand, there is empirical evidence that shows economies of scale in banking, including economies in complying with banking regulations, suggesting larger banks might be able to provide banking services at lower cost than smaller banks.
