In addition to these three fundamental functions of money there are many minor functions. One of the latter, important in banking, is the storing of value against emergencies. As will be explained later, credit-issuers, such as banks and governments, hold on hand reserves of the money commodity. Other commodities may be and are, directly or indirectly, used to store values; the money commodity, however, by reason of durability, stable value, and small bulk, may perform this function better than other commodities.
Moreover, just as money acts as a means of storing values and making payments over periods of time, it is used to facilitate payments over distances, a capacity which rests upon money's common acceptability in distant marts and upon its portability. This function has been very much reduced by credit operations, but continues for the settlement of ultimate balances.
