Key Takeaways
- People and companies use money as a valuable medium of exchange, enabling them to trade effectively without being constrained by barter.
- Money is good because it is interchangeable with other money of the same value (fungible), lasts over time (durable), is easy to carry (portable), is easy to identify (recognizable), and its value does not change quickly (stable). These characteristics all help lower the costs and effort involved in people trading with each other (transaction costs).
- Today’s economies use several forms of money: government-issued currency, fiat money, market-determined money, cryptocurrencies, and money substitutes such as checks or electronic credits.
- Fiat currencies are not backed by any physical substance but by the stability of the issuing government and its economic power, which allows it to manipulate the money supply for economic purposes.
- Digital currencies, such as cryptocurrencies, have certain attributes of money, are speculative investments, and, in some circumstances, serve as legal mediums of exchange, as in El Salvador.
What Is Money?
Explaining Money: Key Characteristics: Money is a unit of account, a store of value, and a standard of deferred payment. It serves as the medium of exchange and promotes transactions in an economy. Its main qualities are fungibility and durability, which lower transaction costs. Therefore, for buyers and sellers, it is less costly to make deals with money than to trade in barter. Most monetary systems are based on standard currencies issued by central banks. But the nature of money has changed over time, and today it encompasses fiduciary media and electronic cryptocurrencies.
Functionality of Money in Economic Transactions
Money is a liquid asset, used to enable the exchange of values. It is a means of transaction between persons and entities. It is also a unit of account for measuring the value of other things and a store of value.
Before money, most economies used barter. People exchanged goods they had for what they needed. This led to the problem of double coincidence of wants. Both parties had to want what the other party offered in order for trade to occur. Money solves this by acting as an intermediary good.
The earliest known forms of money were agricultural goods, such as grain or animals. These items were in high demand, and traders understood they could use or trade them again in the future. Other early forms of money include cowrie shells, cocoa beans, and agricultural equipment.
As the economy became more complex, money was standardized into currencies. This reduced transaction costs, since it was easier to quantify and compare values. Also, the money representations became increasingly abstract, from precious metals and engraved coins to paper notes and, in the modern period, electronic records.
Key Characteristics that Define Money
To lower transaction costs and facilitate exchanges, money must be fungible, durable, portable, recognizable, and stable.
Money Should Be Fungible
“Fungible” denotes that items can be exchanged or swapped for another object of equal worth; money units should be interchangeable.
For instance, metal coins must have a defined weight and purity. Commodity money should be of fairly uniform quality. If money is a non-fungible good, there are transaction costs, implying that the units of money must be valued individually before an exchange may occur.
Money Should Be Durable
Money must be durable enough to be used for many future transactions. A perishable good or one that deteriorates rapidly is less valuable for future exchanges. Using a non-durable product as money contrasts with money’s inherent future-oriented use and value.
Money Should Be Portable
Money must be easy to carry and split. A meaningful amount should fit on a person’s person or be transported. Goods that are hard or cumbersome to carry require physical transportation, thereby incurring transaction costs.
Money Should Be Recognizable
The good must be easily identifiable to users in terms of legitimacy and quantity, so they can agree to the terms of an exchange. With a non-recognizable good like money, transaction costs are incurred in authenticating the items and agreeing on the quantity needed for an exchange.
Money’s Supply Should Be Stable
The supply of money should stay stable over time. This helps keep its value steady. If money is not stable, its value can rise or fall before the next transaction. This creates transaction costs due to changes in scarcity or abundance.
How Is Money Used?
People mostly use money as a medium for exchanging objects of value. However, they also use it for secondary purposes, such as storing value.
The Role of the Unit of Account
People use money as a measure of value for all kinds of commodities and services because they use it to buy and sell them.
That is, money tracks the changing value of things over time and across many transactions. People use it to compare valuations of different combinations or quantities of products and services.
As a unit of account, money enables earnings and losses to be recorded, a budget to be balanced, and a company’s total assets to be valued.
The Importance of Money as a Store of Value
Money, as a means of exchange, is inherently forward-looking. This means it can be used to preserve a monetary value for future use without that value deteriorating.
So when people trade things for money, that money has a particular value that can be used in subsequent trades. This ability to function as a store of value makes it easier to save for the future and to transact over great distances.
Understanding Money as a Standard for Deferred Payments
Money is universally accepted and retains its value. So it can move value over time as credits and debts .
One individual can loan another a certain amount of money for a certain period of time and receive a different amount back at some future date.
Exploring the Various Types of Money
Market-Driven Forms of Money
Markets are a spontaneous order, and money can come from that. As merchants barter for different things, some goods will be more convenient than others because they offer the optimal mix of the five attributes of money: durability, portability, divisibility, uniformity, and acceptability.
In time, these things may be attractive for their use as objects of commerce, rather than for their practical purpose. Eventually, people may want a better future.
Historically, precious metals like gold and silver have been widely used as market-determined currencies. They were in high demand in various cultures and nations. In today’s cashless economies, cigarettes, instant noodles, and other non-perishable products are often used by consumers as market-determined alternatives to cash.
Understanding Government-Issued Currency
Governments generally control the form of money as currency, standardizing coins or notes to reduce transaction costs.
The government may declare some currency legal tender. In other words, courts and government entities must accept that type of money as a final settlement of payment .
Seigniorage is the difference between a currency’s face value and the cost of producing it. The government benefits from seigniorage by issuing money.
For example, if it costs only $10 to print a $100 bill, the government will make a $90 profit on every bill it publishes. But governments that rely too much on seigniorage can end up debasing their currency.
The Concept and Impact of Fiat Currency
Fiat currency is currency that is not representative of any commodity. Many countries issue fiat currency . Instead, fiat money is supported by the issuing government’s economic power. It gains its worth from supply and demand and the stability of the government.
Fiat money allows the government to pursue its economic strategy by expanding or contracting the money supply. In the United States, the Federal Reserve and the Treasury Department monitor different components of the money supply to control and alleviate monetary problems.
Fiat money isn’t backed by a genuine commodity . It’s the government’s responsibility to ensure that fiat money has the 5 necessary features.
The International Monetary Fund (IMF) and World Bank are the world’s supervisors of international currency exchange. Governments may also try to stabilize the currency on international markets by imposing capital controls or pegging it to another currency.
Substitutes for Money and Fiduciary Instruments
Merchants and traders sometimes exchange money for replacements to lighten the load of carrying so much currency. These substitutes may be written assertions of debt, to be redeemed later. These declarations can obtain attributes of money, especially when used by traders in place of actual currency.
Thus, in the days of old, banks would send bills of exchange to their depositors, specifying the sum placed and the conditions for its redemption. The depositor would not go to the bank to withdraw money for payments; instead, they would simply trade their bills. The recipient may redeem or trade them as they please. This usage of money substitutes can make money more portable and durable, and lower the cost of storage. However, money substitutes also have risks. This is called fractional reserve banking . It means banks can create more bills than they have money to redeem . A bank run might occur if too many people try to withdraw their money at once.
Fiduciary media are money substitutes that enter circulation and are not fully backed by the base money. Contemporary examples of fiduciary media include paper checks, coins, and electronic credit.
The Role of Cryptocurrencies in the Monetary System
Lately, there have been digital currencies that lack a physical form, such as Bitcoin. Unlike electronic bank records or payment systems, these virtual currencies are not issued by a government or other central entity. Some of the features of money are found in cryptocurrencies, which are sometimes used in online transactions.
Cryptocurrencies are not often used for day-to-day transactions but rather used as investments or stores of value. Some countries, including El Salvador, take them as payment.
What Are the 4 Types of Money?
Money is whatever market participants decide to assign value to and treat as interchangeable. Money is a currency (paper money and coins) issued by the government. The third sort of money is fiat currency, which is 100% backed by the economic might and good faith of the issuing government. The fourth category of money is money substitutes, which are anything that is exchangeable for money at any moment. For example, a check drawn on a bank account is a substitute for money.
What Is the Difference Between Hard and Soft Money?
Hard money is money backed by something of value. Gold or silver, for example . These metals are less susceptible to inflation than soft money, such as printed banknotes, because their supply is limited. Some may see soft money as hazardous because there is no guarantee that more notes will not be created.
Is Cryptocurrency Money?
Cryptocurrency has many of the features of money and is sometimes used as a means of exchange. While many governments treat cryptocurrencies as taxable assets, few treat them the same as foreign currency. In some places, such as El Salvador, Bitcoin has been adopted.
The Bottom Line
Money is not just a medium of exchange. It is also a unit of account and a store of value. It allows us to plan and save economically. The main role of money is as a medium of exchange, facilitating transactions in goods and services by reducing the inefficiencies of barter systems. Its fundamental attributes are frangibility, durability, portability, irreconcilability, and stability, as these qualities lower transaction costs . Money has developed throughout time from agricultural commodities to standardised currencies to cryptocurrencies. That noted, cryptocurrencies are decentralised and not recognised as legal tender in many governments, including the U.S.
