Store of value
A store of value is the function of an asset that can be saved, retrieved and exchanged at a later time, and be predictably useful when retrieved. More generally, a store of value is anything that retains purchasing power into the future.
The most common store of value in modern times has been money, currency, or a commodity like a precious metal or financial capital. The point of any store of value is risk management due to a stable demand for the underlying asset. Money is one of the best stores of value because of its liquidity, that is, it can easily be exchanged for other goods and services. An individual's wealth is the total of all stores of value including both monetary and nonmonetary assets.
Money as a store of valueEdit
Monetary economics is the branch of economics which analyses the functions of money. Storage of value is one of the three generally accepted functions of money. The other functions are the medium of exchange, which is used as an intermediary to avoid the inconveniences of the coincidence of wants, and the unit of account, which allows the value of various goods, services, assets and liabilities to be rendered in multiples of the same unit. Money is well-suited to storing value because of its purchasing power. It is also useful because of its durability.
Because of its function as a store of value, large quantities of money are hoarded. Money's usefulness as a store of value declines if there are significant changes in the general level of prices. So if inflation rises, purchasing power declines and a cost is placed on those holding money.
Workers who are paid in a currency which is experiencing high-inflation will prefer to spend their income quickly instead of saving it. When a currency loses its store of value, or more accurately when a currency is perceived to lose its future purchasing power, it fails to function as money. This causes people to use currencies from other countries as a substitute.
According to the Cambridge cash-balance theory, which is represented by the Cambridge equation, money's ability to store value is more important than its function as a medium of exchange. Cambridge claims that the demand for money is derived from its ability to store value. This is contrary to Fisher economists' belief that demand arises because money is needed for exchange.
Other stores of valueEdit
Examples for stores of value other than money are:
- Bonds - value is guaranteed by a legal contract
- Collectibles, e.g. original art by a famous artist or antiques such as ancient artifacts or ancient coinage
- Gift economy relationships – value is stored as social reputation
- Labor notes (currency)
- Livestock ownership and control (see African currency)
- Fine wine
- Precious metals – ownership in gold, silver, platinum, and palladium
- Real estate – ownership in actual deeds in protectable controllable land
- Stored-value cards – value is physically stored on the cards in the form of binary coded data
While these items may be inconvenient to trade daily or store, and may vary in value quite significantly, they rarely lose all value. It need not be a capital asset at all, merely have economic value that is not known to disappear even in the worst situation. The disadvantage for land, houses and property as a store for value is that it may take time to find a buyer for those assets. In principle, this could be true of any industrial commodity, but gold and precious metals are generally favored, because of their demand and rarity in nature, which reduces the risk of devaluation associated with increased production and supply.
Cryptocurrency's role as a store of value is currently a matter of debate.  The Internal Revenue Service has issued guidance on "virtual currencies" that refers to them as "a medium of exchange, a unit of account, and/or a store of value." The cryptocurrency Bitcoin is often compared by advocates to gold. In their role as a store of value, cryptocurrencies often elicit concern, due to their extreme volatility,  or due to concerns about the emergence of regulation and contradictory handling by governments.
