I often get asked about cryptocurrency. And I immediately become bored. The sort of claims that people have made about this phenomenon, which is historically just another speculative asset, are over-the-top to say the least. There are two realities that seem to be ignored. First, we already have mainstream digital money and have had for a long time, before cryptocurrencies emerged. For example, when the central banks credit reserve accounts held by commercial banks as part of the daily payments system clearing, digitial transactions take place. Similarly, when you go on-line and conduct some bank transactions shifting deposits to other owners (paying bills etc) you are using digital currency. Second, cryptocurrencies are not currencies nor are they money, which makes their name rather misleading. In fact, they are just another speculative, non-money asset that are not backed by anything so we say that the fair value is zero. There is an intermediate asset that has emerged – the so called – Stablecoin – which differs from cryptocurrencies, in that the asset is specifically pegged in some way to some national currency or basket of assets. However, the hype surrounding stablecoins is similar to that which has accompanied the evolution of cryptocurrencies, the point being that the ‘stable’ bit is not backed in anyway by any government guarantees. I also distinguish this class of non-monetary assets from the recent developments in central banking known as – Central Bank Digital Currency – which is really just an extension of the already myriad of digital transactions that central banks conduct every day.
