An economic theory of Islamic finance

Purpose: This paper aims to provide an economic rationale for Islamic finance. Design/methodology/approach Its methodology is simple. It starts with listing the contributions to economic analysis relevant to the required rationale in the theories of banking, finance, price, money and macroeconomics, to identify the main rationale for Islamic finance. A concise description of the author's model for an Islamic economic system, within which Islamic finance can be operational, is provided. Findings The paper finds distinct advantages of Islamic finance, when properly applied within the author's model. Islamic finance can therefore be a candidate as a reform agenda for conventional finance. It opens the door for significant monetary reform in currently prevalent economic systems. Research limitations/implications The first limitation of the paper is that the distinct benefits of Islamic finance are all of macroeconomic types which are external to Islamic banking and finance institutions. They are therefore not expected to motivate such institutions to apply Islamic finance to the letter, without regulators interference to ensure strict application. The second limitation is the necessity to set up enabling institutional and regulatory arrangements for Islamic finance. Originality/value The results are unique as they challenge the received doctrine and provide non-religious rationale for Islamic finance.
