In the FT, Jean-Pierre Landau argues that central banks should introduce central bank digital currency:
A CBDC would protect the pre-eminence of public money in a digitalised economy. It would maintain effective convertibility of private into public money and provide a defence against digital dollarisation.
For that purpose, a CBDC should be as close as possible to cash. It should be a complement, not a substitute, to bank deposits. It should not carry interest. Whether it should be anonymous, as cash currently is in certain limits, is a fundamental social choice. It must be openly debated as the digitalisation of money forces us to reconsider and rethink the place of privacy in our lives.
