The effect of capital adequacy guidelines on large bank holding companies

The United States federal bank regulators imposed numerical capital guidelines in 1981. If these guidelines are binding on bank holding companies, then theoretical evidence suggests that banking organizations may be increasing asset risk. This study tests empirically the hypothesis that the guidelines are binding. Two models of changes in bank holding company equity capital to assets ratios are developed and tested using maximum likehood estimation: a regulatory model and a market model. The results indicate that most large bank holding companies are influenced by regulatory forces.
