I have been commissioned to write the Introduction (Preface) to the upcoming book – The Last Colonial Currency: A History of the CFA Franc – by Fanny Pigeaud and Ndongo Samba Sylla, which is an English version of the original 2018 book, L’arme invisible de la Françafrique. It will soon be published by Pluto Press (UK) – as soon as I finish this introduction. The book is incredibly important because it shows the role that currency arrangements play in perpetuating colonial oppression and supporting the extractive mechanisms that the wealthy have used for centuries to further their ambitions. It also resonates with more recent neoliberal trends where these extractive mechanisms, formerly between the colonialist (metropolis) and the occupied peripheral or satellite nation, have morphed into intra-national urban-regional divides. I am very appreciative for the chance to write this introduction for these great authors. This is Part 1. Part 2 follows tomorrow. And then you can all rush out and purchase the book.
