“…Interest based monetary policy which had been pursued in most of the countries of the world, including in the muslim majority countries had created the problems of under investment spending, unemployment, depressed economic growth rates, perpetual poverty, and periodic financial crisis. In current times, we have plenty of Islamic economic theories, and these theories and principles can easily be implemented for pursuing successful Islamic monetary policy (Selim 2015(Selim , 2019(Selim , 2020, especially for providing access to the lender of last resort services for the Islamic Banks (Selim & Hassan, 2020); for easily financing homes with Ijarah based diminishing Musharaka (Selim 2020a); for eliminating interest in trade or Riba al Fadl in foreign currency transactions (Selim 2021); for pursuing Sukuk based open market operation as part of Islamic Monetary policy (Selim 2015) instead of Treasury Bills and other interest based financial papers and securities; for pursuing interest free financing of infrastructure projects and redesigning it with Qard Hasan so that it will be acceptable to all Islamic Schools of Fiqh (Selim 2020); for providing Islamic business based Takaful insurance where the policy holders are both owners and risk takers and there are no middlemen who often deprive the share and benefits of the policy holders; here Policy holders are active participants and driving forces of such Islamic Business based Takaful Insurance and receive hundreds of thousands of Dinars (Here Dinar refers to Bahraini Dinar where 1 Bahraini Dinar=US$2.65) during their old age when they need it the most, (Selim 2015a); for providing Islamic value based Islamic Cooperative model for poverty elimination (Selim & Farooq, 2020); for permanently eliminating interest costs in trade deficits financing (Selim 2013) but in reality these wonderful Islamic economic theories have not been implemented correctly. This paper is a humble effort to urge nations of the world, especially the members of the Organization of Islamic Cooperation (OIC) countries to truly implement these theories and thus solving all the above problems of poverty, huge interest payments as part of trade deficit financing, unemployment, low income, widespread interest including Riba al Fadl or interest originating in trade, ineffectiveness in monetary policy and so on.…”
