Central banks already issue digital money, but only to a select group of financial institutions. Central bank digital currency would extend this to households and firms. This column examines the proposal for such currency and assesses the opportunities and risks. It argues that while preparations for the launch of Libra have not proceeded according to plan, it has become clear that for central banks, maintaining the status quo is not an option.

Plans by Facebook and its partners to launch a global digital currency have the FinTech sphere buzzing with rumours, and regulators, central banks, and ‘old finance’ worried. This column, part of the Vox debate on the future of digital money, argues that while we may be witnessing a seismic shift in the monetary system, Libra’s role in that shift will be an indirect one. By taking the status quo option off the table, Libra or its next best replica will force monetary authorities and regulators to choose between central bank-managed digital currency and riskier private digital tokens.

New entrants are vying to occupy the space once used by paper bills. This column, part of the VoxEU debate on the future of digital money, proposes a simple framework to make sense of who is attempting to pry our wallets open. It argues that the adoption of new digital means of payment could be rapid and bring significant benefits to customers and society, but that the risks must be tackled with innovative approaches and heightened collaboration across borders and sectors. One approach is for central banks to engage in a public–private partnership with fintech firms to provide a safe, liquid, and digital alternative to cash: synthetic central bank digital currency.

Both proponents and opponents of central bank digital currency have suggested that it would fundamentally change the macroeconomy. This column questions this paradigm, arguing that the introduction of such a currency need not alter the allocation nor the price system. Concerns about central bank digital currency choking investment, cutting into banks’ profits, or increasing the likelihood of bank runs are misplaced.

The idea of a central bank digital currency has prompted a mixed reaction among economists. This column uses a simple theoretical framework to investigate the impact of such a currency on a monopolistic banking sector. There are two main results. First, the introduction of an interest-bearing digital currency increases financial inclusion, diminishing the demand for physical cash. Second, while an interest-bearing digital currency reduces monopoly profit, it need not disintermediate banks in any way. A central bank digital currency may, in fact, lead to an expansion of bank deposits if the resulting competition compels banks to raise their deposit rates.
