Without doubt, money and monetary policymaking has evolved significantly. The original function of money was to allow trade with a standardised unit of account. A monetary policy would originally have implied simply some arrangement of institutional practice so that the right amount of commodity-based money could be used to facilitate the level of trade. It is probably the case, as is still the case in many parts of the world, that large amounts of trade stood outside the monetary system and relied on barter or non-pecuniary grace and favours. Even standardisation was and remains no easy matter as it is no simple task to set the correct relative prices between various types of monies and goods, ensure the absence of counterfeiting, or clipping, and decide on how to get the right amount of money into circulation. We continue to debate whether notes should be limited in denomination and whether monetary policy will have to be rethought once all money is electronic, which is now part of the very near future.
