This book seeks to develop a framework for understanding international reserve and trading currencies that may be supported by more than one country, each of which is associated with a distinctive geopolitical position. This category of global currencies is denoted in this book as a multi-geopolitical currency. To attain its main objective, the book conducted a review of extant theories of the geopolitical economy, reserve currencies and digital currencies as well as implementing the analysis of a DSGE model, in a bid to identify the necessary and sufficient conditions for the ascendancy of a multi-geopolitical currency. These conditions are applied to evaluate the strength and weaknesses of the BRICS currency and its readiness to exploit the opportunities for the evolution of a new global reserve currency that can crowd out the successful and dominant global currency of contemporary times, the US Dollars, amid the threats that may be confronted on the path of the evolution of such a currency. At the end of the day, the author believes that although the BRICS digital coin has a seemingly strong chance to evolve and dominate the international financial system, its success would be substantially dependent on the ability of the promoters of the currency, the BRICS consortium, to not only crush the inherent weaknesses of the BRICS grouping but also to navigate and overcome the myriad of external challenges that will inevitably confront the ascension of the BRICS digital coin. Finally, the book elaborates upon the implications and ripple effects of a successful evolution of the BRICS Digital currency on public policies of countries and private business strategies of global firms.
