What Is a Medium of Exchange?

A medium of exchange is an intermediary instrument or system used to facilitate the purchase ꦯand sale of goods and services between parties.

For a system to function as a medium 🐲of exchange, it must represent a stan💃dard of value. Further, all parties to the transaction must accept that standard.

In modern economies, the medium of exchange is currency. Gold has served as a medium of exchaꦰnge throughout history.

How a Medium of Exchange Works

A traditional barter system only works when both parties to a transaction have something that the other party wants. Even then, it works only when both parties agree on the value of the goods that each is offering. Is one chicken worth two bars of soap or thre🌠e? The haggling must have been endless.

Thus, introducing a medium of exchange allows for greater efficiency in an economy and stimulates an increase in overa🥀ll trading activity. One or both parties can sell tꦛheir product for a number of gold coins, which can then be used to buy the products they want.

Money As a Medium of Exchange

Money enables anyone who possesses it to participate as an equal market player. When consumers use money to purchase an item or service, they are effectively making a bid in𝔉 resp🐼onse to an asking price.

This interaction creates order and predictability in the marketplace. Producers know what 🐽to produce 🐭and how much to charge, while consumers can reliably plan their budgets around predictable and stable pricing models.

If money—as represented by a currency—is no longer viable as a medium of exchange, or if its monetary units can no longer be accurately valued, businesses and consumers loseಞ their ability to plan. M🉐arket volatility will cause the markets to become chaotic.

Prices are bid up, or raised, in response to worries about scarcity and fears of the unknown. Meanwhile, supply diminishes because of hoarding behavior, coupled with an inability of producers to quickly re🥀plenish inventory.

Characteristics of a Medium of Exchange

An effective medium of exchange has certain characteristics. Most of all, its value is widely recꦕognized and reasonably stable. Even so, the proliferation 𒁏of currencies around the world makes it necessary for travelers to exchange their native currency with a local currency in order to do business.

For sheer practicality, a medium of exchange must be dividable into a number of smal൲ler units that can be added or subtracted to equal the payment chargꦚed for a specific product or service.

The governments that 🅘issue currency are responsible for most of their qualities. They must make certain that the currency is made widely available to the public, that it is not easy to copy or reproduce, and that it is available in sufficient quantities as needed.

Some of these characteristics may not apply to cryptocurrency, which has no physical existence. The extreme volatility of cryptocurrency prices may p♎revent them for now from being widely adopted as a means of payment.

Purposes of a Medium of Exchange

As noted, the primary purpose of a medium of exchange is to smooth transactions between parties. A🐲n effective medium of exchange has a reasonably stable value that is known and accepted by all parties.

That relative stability gives currency, as the primary medium of exchange, another important purposeܫ: It can be stored for a long period of time. The concepts of saving and investing evolved from the potential of currencies to serve over the long term as stores of value.

Alternative Currencies As a Medium of Exchange

Alternative currencie꧋s have appeared throughout time during periods of economic duress to spur commerce ಌor buttress a national currency.

In 1907, a cascading series of bank failures caused widespread cash shortages. Companies had to issue company scrip a💮nd other forms of emergency currency in order to pay their workers.

Workers could redeem the scrip for food and services, or they could hold onto it for fuཧture redemption once U.S. dollars became available. Such informal money substitutes are little more than an IOU and depend on the reputation of the issuer for their acceptability as a form of payment.

Example of an Alternative Medium of Exchange

Across the U.S., local currencies have sprung up with the primary purpose of fostering economic growth and sustainability in a region. The best-known case of a thriving local currency is 澳洲幸运5开奖号码历史查询:BerkShares, launched in 2006 and still accepted by so🧜me 350 buꦆsinesses in the Berkshires region of Massachusetts.

The value of BerkShares is pegged to the value of the dollar but the bills are issued at a discount. B𒈔erkShares can be obtained at participating bank branches (nine branch offices of three local banks) in exchange for U.S. dollars at a rate of 95 cen♔ts.

The Bottom Line

In an Encyclopedia Britannica article written in part by Milton Friedman, money is defined as "a commodity accepted by general consent as a medium of economic exchange." In modern economies, the local currency is the universal medium of exchange, except in dire economic circumstances. For example, as Britannica points out, the usual medium of exchange in Germany directly after World War II was cigarettes or cognac.
