Money is any item or verifiable record that is generally accepted as payment for goods and services and repayment of debts or even the establishment of new debts in a particular country or socio-economic context. Money is historically an emergent market phenomenon establishing a commodity money, but nearly all contemporary money systems are based on fiat money. Fiat money, like any check or note of debt, is without intrinsic use value as a physical commodity. It 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".
Such laws in practice cause fiat money to acquire the value of any of the goods and services that it may be traded for within the nation that issues it. The money supply of a country consists of currency (banknotes and coins) and usually includes bank money (the balance held in checking accounts and savings accounts). Bank money, which consists only of records (mostly computerized in modern banking), forms by far the largest part of broad money in developed countries.
