Les crypto-monnaies, unités de compte cryptées ou monnaie cryptée : le cas du Bitcoin et de la Libra
November 13, 2019

La décennie 2009-2019 a vu se développer les crypto-monnaies. Ce que certains appellent des unités de compte cryptées. Cette étude est consacrée à deux d’entre elles : le Bitcoin, créé en 2009, et la Libra, dont les premières devraient apparaître en 2020. Deux crypto-monnaies qui peuvent s’opposer ou se compléter. Unité de compte reconnue, le Bitcoin va vite apparaître aussi spéculatif, l’éloignant du caractère monétaire que certains veulent lui attribuer. A l’inverse, la Libra, monnaie en devenir Facebook, essaie de corriger certains aspects négatifs du Bitcoin, monnaie virtuelle, n’ayant aucune contrepartie réelle. C’est pourquoi, la Libra se veut être un « stable coin », dont l’émission est strictement en relation avec la détention de titres d’Etat ou/et de devises. Pour autant, les autorités bancaires privées et centrales ne semblent pas devoir faciliter son émission. Absentes lors de la création du Bitcoin, elles entendent peser de tout leur poids pour encadrer la Libra et différer sa date de lancement. L’étude, en rappelant ce qui fait l’originalité des deux, entend montrer aussi les raisons qui incitent le monde bancaire, national et international, à la prudence

Cette étude est consacrée aux crypto-monnaies, plus particulièrement à deux d’entre elles, la plus ancienne, le Bitcoin, et la plus récente, annoncée pour 2020, la Libra. Que faut-il entendre par crypto-monnaie ? Pas véritablement une monnaie, mais une unité de compte qui aspire à le devenir, peut-être, utilisant la cryptographie afin de sécuriser ses transactions. Qu’estce alors que la cryptographie ? C’est un ensemble de procédés visant à crypter les informations échangées lors de transactions, c’est-à-dire à les transformer en un message codé compréhensible seulement par ceux qui disposent du code.

    First appeared at AMERICAS QUARTERLY A growing global imbalance threatens to further weaken already vulnerable emerging markets. The massive vaccine disparities between advanced and developing economies may exacerbate what the IMF has dubbed “divergent recoveries”—with dire consequences for Latin America. Despite being home to only 8% of the world’s population, the region has already suffered nearly 30% of all global COVID-19 deaths. The pandemic has also hit GDP and employment ha ...

    China is the world's largest exporter of goods. It is also, by any plausible criterion, a developing country. China's dual status needs to be better reflected in Chinese policies - recognizing its global responsibilities -- and in those of the Western powers - recognizing China's limitations. Across three important agendas - macroeconomics, development assistance, and climate - important differences between China and the West remain, yet none of these issues appears intractable. ...

    Commodity prices have recovered their 2020 losses and, in most cases, are now above pre-pandemic levels (Figure 1). The pace of Chinese growth since 2020 and the economic recovery that has accompanied vaccine rollouts in advanced companies are seen as driving demand upward, while supply restrictions for some items—oil, copper, and some food products—have favored their upward adjustment. Some analysts have started to speak of the possibility of a new commodity price ‘super-cycle’ aft ...

    The projections for United States GDP released by the Federal Reserve on March 17, pointed to a growth rate of 6.5% in 2021, well above December’s 4.2% forecast. Congressional approval of the Biden administration’s $1.9 trillion fiscal package and the vaccination march against COVID-19 explain the rise in the estimate. However, it should not be forgotten that growth in 2021 will follow a fall in GDP of 3.5% last year. While the expected unemployment rate at the end of 2021 is now 4 ...
