Economics has always had a strange and much-debated relationship with money. For a long time, economists – including Nobel laureates such as Merton Miller and Franco Modigliani – regarded money merely as a medium of exchange. But by building on the work of John Maynard Keynes and Hyman Minsky, economists have since moved beyond a narrow focus on the quantity of money to consider its structural influence on the real economy and the financial system.

A structural understanding of money and finance becomes even more important in an increasingly digitalised and cashless world because there is a growing need for policymakers to operate not just as market fixers but as proactive market shapers. A cashless world not only changes people’s relationship with money and creates new opportunities for how it is managed or even conceived; it also puts new pressure on central banks to reimagine their role and become more innovative.
