Some countries have issued their own central bank digital currencies, and many European economists favour such a currency too. This column shows that when properly designed, central bank digital currencies can help stabilise the financial and monetary system. Furthermore, a complementary currency backed by a central bank digital currency can not only compensate for the demise of commercial bank money, but it can also democratise money creation. The authors also show that complementary currencies can have higher multiplier effects on local expenditure, allow central banks to control circulation velocity, and help countries in currency crises.
