Cryptoassets (or ‘cryptocurrencies’) are notoriously volatile. For example, in November 2018, Bitcoin – one of the more stable cryptoassets – lost 43% of its value in just 11 days. This kind of volatility makes it difficult for cryptoassets to function as money: they’re too unstable to be a good store of value, means of exchange or unit of account. But could so-called ‘stablecoins’ solve this problem and finally provide a price-stable cryptoasset?
The topics of central bank digital currency (CBDC) and distributed ledger technology (DLT) are often implicitly linked. The genesis of recent interest in CBDC was the emergence of private digital currencies, like Bitcoin, which often leads to certain assumptions about the way a CBDC might be implemented – i.e. that it would also need to use a form of blockchain or DLT. But would a CBDC really need to use DLT? In this post I explain that it may not be necessary to use DLT for a CBDC, but I also consider some of the reasons why it could still be desirable.
