Michel Camdessus Central Banking Lecture – Washington, 14 September 2022 Ethics of currency: a possible guide for central bankers? Speech by François Villeroy de Galhau, Governor of the Banque de France  Press contact: Mark Deen (mark.deen@banque-france.fr), Déborah Guedj (deborah.guedj@banquefrance.fr)  Page 1 sur 10 Ladies and Gentlemen, It is my great pleasure to be in Washington with you today, and to deliver this speech in honour of Michel Camdessus. I would like to take this opportunity to pay a special tribute to him, and express my personal gratitude. Michel is not only one of my predecessors as a Governor of the Banque de France, but also a friend of mine and – yes – a master. My speech was prepared with his precious help, so today you can almost enjoy a “Camdessus Lecture by Michel Camdessus himself”. The theme we chose together, the “ethics of currency”, has guided him throughout his career. In the murky waters that we central bankers are navigating, it should more than ever serve as a golden thread. I will briefly discuss the reasons why I dare to talk about the ethics of currency (I), then elaborate on the golden triangle of trust today (II) and finally raise the question as to whether the international dimension of trust can still inspire us (III). I. Why I dare to talk about the ethics of currency Before going any further, we must find a common definition of “ethics”. Is it possible to take this word as a synonym for “morality”?
For centuries, this question has been the “bridge of donkeys” (pons asinorum) for philosophers’ apprentices. Supporters of the synonym theory highlight a common etymology between the two words – morality is the Latin translation of Greek ethos. Despite their initially identical meanings, the two words nevertheless have followed different paths over time: “morality” can be described as a “hard concept”, similar to the fundamental rules engraved on Moses’ stone tablets or in the code of Hammurabi. In contrast, “ethics” refer to a softer and less binding concept, a kind of existential version of morality with a more personal dimension. I will use the word ethics in that way in this speech. The question of interest rates is a noteworthy example of the way a moral prohibition can evolve into a more flexible and ethical approach. From a moral overall ban, ethically “fair” interest rates have been progressively distinguished from usury rate, with the latter still being forbidden. Page 2 sur 10 “Homo economicus” invented currency very early in human history, and it is striking that almost as soon as currency was born, countless abuses were seen as well: manipulation of gold or silver weight in coins, skewing of scales, and so forth. Men therefore quickly summoned ethics to define how to govern its use. However, human kind has also shown a tendency to exempt itself from the rules it had previously established, before setting new rules again in order to respond to the problems caused by deregulation.
