payment schedules associated with the uniform rate of interest. A variable-rate instrument, such as many consumer mortgages, will reflect the standard rate for deferred payment set by the central bank prime rate, increasing it by some fixed percentage. Other instruments, such as citizen entitlements, e.g. "U.S. Social Security", or other pensions, may be indexed to the rate of inflation, to provide a reliable value stream. Trading in stock markets or commodity markets is actually trade in underlying assets which are not wholly financial in themselves, although they often move up and down in value in direct response to the trading in more purely financial derivatives. Typically commodity markets depend on politics that affect international trade, e.g. boycotts and embargoes, or factors that influence natural capital, e.g. weather that affects food crops. Meanwhile, stock markets are more influenced by trust in corporate leaders, i.e. individual capital, by consumers, i.e. social capital or "brand capital" (in some analyses), and internal organizational efficiency, i.e. instructional capital and infrastructural capital. Some enterprises issue instruments to specifically track one limited division or brand. "Financial futures", "Short selling" and "financial options" apply to these markets, and are typically pure financial bets on outcomes, rather than being a direct representation of any underlying asset. Broadening the notion The relationship between financial capital, money, and all other styles of capital, especially human capital or labor, is assumed in central bank policy and regulations regarding instruments as above. Such relationships and policies are characterized by a political economy – feudalist, socialist, capitalist, green, anarchist or otherwise. In effect, the means of money supply and other regulations on financial capital represent the economic sense of the value system of the society itself, as they determine the allocation of labor in that society. So, for instance, rules for increasing or reducing the money supply based on perceived inflation, or on measuring well-being, reflect some such values, reflect the importance of using (all forms of) financial capital as a stable store of value. If this is very important, inflation control is key - any amount of money inflation reduces the value of financial capital with respect to all other types. If, however, the medium of exchange function is more critical, new money may be more freely issued regardless of impact on either inflation or well-being. Economic role Socialism, capitalism, feudalism, anarchism, and other civic theories take markedly different views of the role
