The economists’ solution – often called the Chicago Plan – was to remove commercial banks from the money-creating business. One of the main problems of a central bank digital currency (CBDC) is that it would compete with old-fashioned bank deposits. With the digital money supply increasing in line with the economy’s potential growth, roughly as Friedman advised, inflation would soon come under control. Non-bank lenders like Apollo Global Management (APO.N) would have an enhanced role under the digital Chicago Plan. At present, there’s little chance of the digital Chicago Plan coming to pass.
