Imagine, for starters, if central banks were to take back the power to create money and then issue it to commercial banks, while simultaneously requiring them to hold 100% reserves for the loans that they make – meaning that every loan would be backed by someone else’s savings, or the bank’s own capital. It would certainly separate the role of providing money from the role of providing credit, so helping to prevent the build-up of debt-fuelled credit bubbles that burst with such deep social costs.
