The Economics Committee of the UK House of Lords reported in Jan 2022 that a CBDC is a 'solution looking for a problem'. It might cause extra financial instability, i.e. worse than today's fiat currencies.

One member of this Committee is Lord (Mervyn) King, last but one Governor of the Bank of England.

Of course, the Chancellor, Jeremy *unt and the current BoE Governor are ploughing on.
