Money is commonly expected to serve as both a medium of exchange and a store of value, but these functions can create different incentives. To function as a medium of exchange, money must move between participants in the economy. To function as a store of value, it must be retained for future use. The qualities that make money attractive to hold can therefore also make it easier to withdraw from circulation. However, the store-of-value function should not be treated as identical to the ability to store money at little or no cost. Preserving purchasing power and retaining a monetary balance are related but conceptually distinct characteristics. ## Medium of exchange and store of value A medium of exchange is a dynamic function. Money performs this function when it changes hands in return for goods, services or other assets. Money held in a wallet or stored in a bank vault is not actively functioning as a medium of exchange at that moment. It performs this function when it is transferred from one participant to another. A store of value is a temporal function. Money performs this function when it allows purchasing power received in the present to be used in the future. Someone can sell a good or provide a service today, retain the money received and use it later. The ability to transfer purchasing power across time is useful. People do not necessarily want or need to spend all of their income as soon as they receive it. They may need to prepare for future expenses, emergencies, periods when they cannot work or purchases that require income to be accumulated over time. The tension identified by Gesell does not arise merely because people retain money for future use. It arises when the qualities of money allow it to be withheld from exchange for prolonged periods at comparatively little cost. ## Store of value A store of value is an asset’s ability to preserve purchasing power through time. It enables someone to receive value in the present and retain a meaningful proportion of that value for future use. An asset does not need to preserve purchasing power perfectly to function as a store of value. Its future value may be affected by inflation or deflation, changes in market demand, risk of loss, maintenance and storage costs or changes in the condition of the asset. These factors can make an asset more or less effective as a store of value, but they do not necessarily prevent it from performing that function. Money acts as a store of value when it can be retained and later exchanged for goods and services without losing too much purchasing power. The relevant question is how much the money will purchase when it is eventually used, not merely whether the same nominal number of monetary units remains in the holder’s possession. For example, someone might retain £100 for a year and still possess £100 at the end of that period. The nominal quantity has remained unchanged, but its purchasing power may have increased or decreased as prices changed. The effectiveness of the money as a store of value depends on the amount of goods and services the £100 can purchase, rather than on the nominal balance alone. ## Storability Storability describes how easily and inexpensively an asset or monetary balance can be retained through time. For the purposes of this analysis, storable money is money that can be held for future use without physically deteriorating, expiring, requiring substantial maintenance or imposing significant storage or carrying costs. Storability does not describe whether money’s purchasing power remains stable. A form of money can be easy to store while losing purchasing power. Conversely, an asset can preserve purchasing power while being difficult or expensive to store. The distinction can therefore be stated simply: * **Store of value:** How effectively money preserves purchasing power through time. * **Storability:** How easily and inexpensively a monetary balance can be held through time. These two characteristics often occur together, but one does not necessarily imply the other. ## Store of value and storability are not identical An asset can be physically durable and inexpensive to retain while still experiencing substantial changes in purchasing power. Its physical storability may be high even though it is an unreliable store of value. The opposite is also possible. An asset may preserve purchasing power reasonably well while imposing meaningful costs on its holder. Property, machinery and other physical assets may retain or increase their market value while still requiring maintenance, security, insurance and administration. It is therefore useful to consider two separate questions: 1. How much purchasing power will the asset preserve? 2. What costs must its owner bear while retaining it? The first concerns the store-of-value function. The second concerns storability and carrying costs. ## Gold as an example Gold illustrates how store of value and storability can operate together. Gold can function as a store of value because it is durable, scarce and widely valued. However, its purchasing power can still fluctuate as the market value of gold changes relative to other goods and services. Gold is also physically storable. It does not rot, rust or expire, and its high value relative to its size allows substantial wealth to be held in a compact form. This makes it easier to retain than many ordinary commodities. Gold is not entirely costless to store. Large holdings may require secure facilities, insurance and protection against theft. Nevertheless, it can generally be retained for long periods without the deterioration experienced by food, manufactured inventory and many other forms of tangible wealth. Gold therefore combines relatively strong physical storability with the ability to preserve purchasing power over extended periods. From Gesell’s perspective, this combination becomes important when gold is used as money because it allows purchasing power to be withdrawn from circulation and retained with comparatively little loss. ## Fiat money as an example Fiat money also demonstrates why storability and store of value should be assessed separately. Physical banknotes and digital bank balances can usually be retained without physically deteriorating. Digital balances do not rot, rust or become technologically obsolete in the same way as many physical goods. In this sense, fiat money is highly storable. However, its purchasing power may decline because of inflation. Someone can retain the same nominal balance while becoming able to purchase fewer goods and services with it. Fiat money can therefore be easy to store without being a perfect store of value. Its nominal storability remains high even when its real purchasing power changes. Inflation may create a cost for holding fiat money, but this cost is not necessarily stable or predictable. During periods of deflation, the purchasing power of money may increase, making monetary retention more attractive. Storability and purchasing-power changes must therefore be considered independently. ## Money subject to a carrying cost The distinction can also be illustrated by imagining money that preserves reasonably stable purchasing power but imposes a recurring cost on its holder. Gesell proposed stamped money that required holders to purchase and apply stamps periodically for the money to remain valid at its full nominal value. The currency could continue to provide a unit of account and preserve a meaningful amount of purchasing power, but retaining it would involve an ongoing expense. The money would remain physically storable. A person could still keep it for future use. However, it would no longer be possible to hold it indefinitely without cost. This example demonstrates that imposing a carrying cost on money does not necessarily require the monetary unit itself to experience unstable purchasing power. The cost can be applied to the act of retaining a monetary balance rather than through a decline in the value represented by each unit. The same conceptual distinction could be applied to a durable asset such as gold. Imagine a system in which all monetary gold holdings were recorded and a small percentage was collected periodically. Gold would remain physically durable and could continue to preserve purchasing power, but retaining a balance would incur an institutional carrying cost. Such a system would be difficult to administer if people could conceal their gold. Nevertheless, it illustrates that an asset can remain durable and usable as a store of value while also becoming costly to hold. ## Saving Saving means setting aside part of one’s present income or wealth for future use. People save because they expect to have future needs and because their capacity to earn income may change over time. Savings can be held in several forms. People may decide to retain money, deposit money with a financial institution, lend it to another participant, invest it in a business, purchase financial assets or acquire buildings, equipment or other physical assets. Saving therefore does not necessarily mean holding money idle. It describes the broader act of transferring present income or wealth into the future. Money can be used as a vehicle for saving, particularly over short periods. Someone may need to retain part of their income until rent, bills or other expenses become due. A business may retain money to meet payroll, purchase supplies or manage unexpected costs. These balances support the practical use of money across time. The ability to save should therefore be distinguished from the decision to maintain large or prolonged idle monetary balances. ## Hoarding money For the purposes of this analysis, hoarding money means maintaining unusually large or prolonged idle monetary balances rather than spending, lending or investing them. The important characteristic is not simply that the money is being saved. It is that the medium of exchange is being retained without being made available for current exchange or productive use. A person who saves by investing in productive equipment has transferred purchasing power to the seller of that equipment. A person who lends money makes it available to another participant, assuming the borrower subsequently uses it. A person who purchases goods or services returns the money directly to circulation. By contrast, money held idle remains under the exclusive control of its holder and is not made available to another participant. It retains the potential to facilitate exchange but does not actively perform that function. Saving and hoarding should not therefore be treated as synonyms: * **Saving** is the general act of setting aside present income or wealth for future use. * **Hoarding money** is a particular form of saving in which the medium of exchange is held idle for a prolonged period. Not every retained monetary balance should be considered hoarding. People and businesses require working balances to manage the period between receiving income and making payments. The distinction concerns the scale, duration and purpose of the balance. ## Financial intermediation Money deposited with a bank is not necessarily withdrawn from economic use in the same way as physical money stored privately. Deposits may support lending, and the money made available through loans may then be spent or invested by borrowers. Similarly, money lent through financial markets becomes available for another participant to use. Saving through a deposit, loan or investment can therefore support continuing economic activity. However, financial intermediation does not guarantee that retained income will be converted into present spending or productive investment. Banks may decline to lend, potential borrowers may be unwilling to borrow or the recipients of money may continue to accumulate liquid balances. The distinction between saving and hoarding is consequently based on what happens to purchasing power after it is retained. Saving could make purchasing power available to others, while hoarding can mean leaving it idle and under the control of its existing holder. ## Gesell’s distinction Gesell did not deny that people need to save. His objection was to the assumption that idle money should be the ideal instrument for preserving and accumulating wealth. Ordinary goods and productive assets generally impose costs on their owners. Food deteriorates, merchandise requires storage, buildings require maintenance and machinery becomes obsolete. Money can often be retained more easily and at a lower cost than the goods and services for which it is exchanged. Gesell believed that this difference gave holders of money a special advantage. The owner of money could postpone buying, lending or investing until sufficiently favourable terms were available, while producers and sellers might face ongoing costs and pressure to complete an exchange. His proposal was not intended to eliminate saving. People could continue to preserve wealth through deposits, loans, buildings, equipment and other real or financial assets. His aim was to reduce the incentive to use idle balances of the medium of exchange as the preferred means of preserving and accumulating wealth. ## The expected return from holding money The incentive to retain money depends on its expected net return. This includes both changes in purchasing power and any costs associated with holding the monetary balance. If money is expected to appreciate, the holder may benefit from retaining it because the same balance will purchase more goods and services in the future. If it is expected to lose purchasing power, retaining it becomes less attractive. Carrying costs operate separately from changes in purchasing power. Money could preserve stable purchasing power while still imposing a cost on its holder. It could also appreciate while being subject to a carrying charge. What matters to the holder is the combined effect. If the expected appreciation of the money is greater than its carrying cost, retaining it may still provide a positive net return. If the carrying cost is greater than the expected appreciation, the holder faces a negative net return from leaving the balance idle. This is why value preservation and low-cost storability should not be treated as the same problem. The purchasing power of a monetary unit can remain reasonably stable while the monetary system imposes an ongoing cost on prolonged possession. The ability to preserve purchasing power can help make money acceptable for exchange and useful for short-term saving. The characteristic that becomes central to Gesell’s analysis is the ability to withhold money from circulation for prolonged periods at comparatively little cost.
