Central banks across the world are considering sovereign digital currencies. This column argues that these currencies could transform all aspects of the monetary system and facilitate the systematic and transparent conduct of monetary policy. In particular, a central bank digital currency can serve as a practically costless medium of exchange, a secure store of value, and a stable unit of account. To achieve this, the currency would be account based and interest bearing, and the monetary policy framework would target true price stability.

If the share of payments made by cryptocurrencies increases, government-issued money will face market competition from private issuers. The column argues that, even if this system could maintain price stability in an economy, the market would not provide the socially optimum amount of money. A government could still, however, maximise social welfare using monetary policy in response to peg the real value of money. The threat of competition from private monies may therefore impose welcome market discipline on any government that issues currency.

The cryptocurrency Bitcoin has attracted widespread interest, in large part due to wild swings in its valuation. This column considers an earlier rise in the Bitcoin price to investigate what is driving the currency’s price spikes. The 2013 rise was caused by fraudulent trades taking place at the largest Bitcoin currency exchange at the time. This finding has implications for policymakers as they weigh what, if anything, to do about regulating cryptocurrencies in light of the record high Bitcoin valuation that many fear is a bubble.

The blockchain technology underlying Bitcoin and other cryptocurrencies is attracting growing interest. This column argues that if transactions facilitated by this technology become pervasive, it will have implications for the conduct (and success) of central bank monetary policy. Central banks should embrace the technologies that underpin cryptocurrencies, or risk being cut out from intermediation and surveillance and also risk payment service providers moving to other currency areas with an institutional environment that is more appealing for buyers and sellers.
