Cryptocurrencies’ market capitalization has grown rapidly in recent years. This blog post analyzes the role of macro factors as possible drivers of cryptocurrency prices. We take a high-frequency perspective, and we focus on Bitcoin since its market capitalization dwarfs that of all other cryptocurrencies combined. The key finding is that, unlike other asset classes, Bitcoin has not responded significantly to U.S. macro and monetary policy news. This disconnect is puzzling, as unexpected changes in discount rates should, in principle, affect the price of Bitcoin.
Bitcoin, and more generally, cryptocurrencies, are often described as a new type of money. In this post, we argue that this is a misconception. Bitcoin may be money, but it is not a new type of money. To see what is truly new about Bitcoin, it is useful to make a distinction between “money,” the asset that is being exchanged, and the “exchange mechanism,” that is, the method or process through which the asset is transferred. Doing so reveals that monies with properties similar to Bitcoin have existed for centuries. However, the ability to make electronic exchanges without a trusted party—a defining characteristic of Bitcoin—is radically new. Bitcoin is not a new class of money, it is a new type of exchange mechanism, and this type of exchange mechanism can support a variety of forms of money as well as other types of assets.
