Digital currencies involve tradeoffs. Libra resolves them less favorably than other projects, and less favorably than CBDC.
When confronted with the choice between the status quo and a new financial architecture with CBDC, most central banks have responded cautiously. But Libra or its next best replica will take this choice off the table – the status quo ceases to be an option. The new choice for monetary authorities and regulators will be one between central bank managed CBDC on the one hand and – riskier – private digital tokens on the other. Central banks have a strong interest to maintain control over the payment system as well as the financial sector more broadly and to defend the attractiveness of their home currency. Nolens volens, they will therefore introduce ‘Reserves for All’ or promote synthetic CBDCs. In economics, things take longer than one thinks they will, as Rudi Dornbusch quipped, but then they happen faster than one thought they could.
