A 'standard of deferred payment' is the accepted way (in a given
market) to settle a
debt. For example, while the
gold standard reigned,
gold or any
currency convertible to gold at a fixed rate constituted such a standard. As of
2003, the
US dollar and the
euro are the most generally accepted standards for international settlements.
However, for certain kinds of transactions (such as for illegal goods like narcotics or weapons), gold or diamonds may be preferred as the
medium of exchange — there being no recourse in case of
counterfeit currency being used — and there is rarely any deferral of payment: if there is, it will most likely be stated in dollars.
This is distinct from the
store of value function which relates to the saving, storing, and retrieval of value, and from the
unit of account function which requires fungibility so accounts in any amount can be readily settled. It is also distinct from the
medium of exchange function which requires durability when used in trade, and a minimum of opportunity to cheat others — as the diamond or gold example makes obvious.
When
currency is stable,
money can serve all four functions. When it isn't, or when complex and volatile forms of
financial capital are involved, it becomes important to identify a single standard of deferred payment to avoid cheating by selecting a denominator of debt that one knows is dropping in value.
Historically, there have been many times when
creditors have had to hide from
debtors to avoid being paid off in near worthless currency.
Time-based currency such as
Ithaca Hours establishes fixed amounts of human labour as the only standard of deferred payment.
