This paper analyzes multiple reserve requirements of the type that have been imposed by a number of developing countries. We show that previous theoretical work on this topic has not succeeded in providing a social welfare rationale for the existence of multiple reserve requirements. We go on to present a model in which it is possible for a multiple reserves regime to improve social welfare relative to simpler regimes involving reserve requirements and/or deposit taxes. We demonstrate the empirical plausibility of our approach by providing a case study of Mexico, a country with extensive historical experience with multiple reserve requirements.
