Money is anything that is generally accepted as payment for goods and services and repayment of debts.[1][2] The main functions of money are distinguished as: a medium of exchange, a unit of account, a store of value, and occasionally, a standard of deferred payment.[3][4]



Money originated as commodity money, but nearly all contemporary money systems are based on fiat money.[3] Fiat money is without value as a physical commodity, and derives its value by being declared by a government to be legal tender; that is, it must be accepted as a form of payment within the boundaries of the country, for "all debts, public and private".



The money supply of a country consists of currency (banknotes and coins) and demand deposits or 'bank money' (the balance held in checking accounts and savings accounts). These demand deposits usually account for a much larger part of the money supply than currency.[5][6] Bank money is intangible and exists only in the form of various bank records. Despite being intangible, bank money still performs the basic functions of money, being generally accepted as a form of payment.[7]
