This article identifies the barriers to entry of the CEMAC banking market and analyzes the behavior of banks in a competitive situation. The allotment efficiency scores, for the period 2000 to 2014, reveal the CEMAC banks’ dissuasive strategies. The highest scores indicate more restrictive regulations and therefore higher barriers. The degree of restriction of banking regulation is related to net interest margins. Thus, a 85% increase in the level of restrictions to entry results in an increase of 8,71% of the interest rate loans, with considerable differences between countries. We suggest the implementation of a dynamic approach to provisioning as well as of business intelligence within banks.
