The evolution and importance of money: from barter to blockchain
Money, as any item or medium of exchange representing perceived value, plays a crucial role in our daily lives. People accept it for the payment of goods and services and the repayment of loans, facilitating transactions and driving financial growth. Economists define money, its origin, and its worth. Here are the various characteristics of money that make it a practical and essential part of our lives.
History and evolution of money
Before money, people bartered to get goods and services.
Two individuals, each with something the other wanted, would trade. Bartering had issues. It could have been more easily transferable and divisible. For example, if someone had wheat but needed cloth, they had to find someone who had cloth and wanted wheat. If that person only had shoes and needed wheat, a complicated chain of trades had to happen. It made bartering tiring, confusing, and inefficient. Even if a trade partner was found, agreeing on the value was another challenge. How many units of cloth equal a bushel of wheat?
Commodity money solved the problems associated with bartering.
Commodity money, a type of good that functions as a currency, was a significant development in the history of money. It is a form of money with intrinsic value, meaning it is valuable in and of itself, not just because it is used as money. In the 17th and early 18th centuries, American colonists used beaver pelts and dried corn for transactions. These commodities had generally accepted values and were durable, portable, and easy to store. A more advanced example of a commodity is gold. For centuries, gold-backed paper currency was in use until the 1970s.
The transition from commodity money to fiat money
Gold, a scarce resource, needed help meeting the needs of rapidly growing economies. People left commodity money and started using fiat money. Fiat money is a currency a government declares legal tender, but a physical commodity like gold or silver does not back it. Instead, its value comes from the trust in the government that issues it. The government issues fiat currency and derives its value from the government’s trust and authority.
Unlike older currencies, the value of fiat money is not backed by a physical commodity like gold or silver. Instead, its value comes from the trust in the government that issues it. This trust-based value of fiat money is a crucial aspect of our financial system, providing greater flexibility and allowing governments to manage and stabilize the economy more effectively. This trust underpins the stability of our economic system, reassuring us of the value of our money.
Modern money: value and inflation
Today, the value of money, including the dollar and most other currencies, is mainly determined by its purchasing power, which is affected by inflation. It means that printing more money doesn’t create wealth. Money’s value comes from the balance between our need for goods, our desire for them, and our belief in what has value. Money is valuable because it lets us buy the products and services we need and want. The strength of a currency depends on the health of its economy, stable supply and demand, and the trust people place in it.
Measuring the money supply: categories and components
Money is measured as the money supply, which refers to the total amount of monetary assets available in an economy at a specific time. It includes various forms of money, such as cash, coins, and balances held in checking and savings accounts.
Understanding the money supply is crucial for economists and investors as it helps them to understand inflation (rising prices) or deflation (falling prices).
Categories of money supply
Economists and investors need to know the money supply in the economy to understand inflation (rising prices) or deflation (falling prices). To make this easier, they categorize money into three main groups: M1, M2, and M3. These categories help analyze the total amount of monetary assets available and their liquidity levels.
M1 is the narrowest category and includes the most liquid forms of money, meaning it’s ready to be spent.
It includes physical cash (coins and bills), checking accounts, traveler’s checks, and other easily accessible deposits, like savings accounts.
M2 is a broader category that includes all the money in m1
M2 includes savings and other time-related deposits, certain retirement accounts, and non-institutional money market funds. M2 represents money that can be quickly converted into cash but is not used directly for transactions. It provides a more comprehensive view of the money available in the economy.
M3, the broadest category, includes everything in m2
M3 includes large-time deposits, institutional money market funds, short-term repurchase agreements, and other significant liquid assets. M3 gives the entire picture of the total money supply in the economy, including more oversized, less liquid financial assets.
The role of Central Banks in regulating the money supply
Central banks play a crucial role in regulating the money supply and ensuring economic stability through various monetary policy tools. Their management of the money supply through adjustments in interest rates and open market operations, such as buying or selling government securities, is critical to maintaining the stability of our economies. Understanding these mechanisms can give us a deeper insight into the factors influencing our financial well-being.
By raising or lowering interest rates, central banks can either encourage borrowing and spending to stimulate economic growth or discourage it to curb inflation.
Additionally, central banks are increasingly exploring the development of Central Bank Digital Currencies (CBDCs), digital forms of national currencies.
CBDCs aim to enhance the efficiency and security of payment systems, provide a reliable digital alternative to private cryptocurrencies, and ensure central banks retain control over the monetary system in an increasingly digital economy. Through these measures, central banks strive to maintain price stability, promote sustainable economic growth, and ensure the overall health of the financial system.
How money is created?
In current economic systems, money is created through two main processes: legal tender and bank money.
Legal tender, or narrow money (M0)
It is the cash a central bank creates by minting coins and printing banknotes. The government directly issues this form of money, which includes physical currency in circulation.
Bank money or broad money (M1/M2)
Private banks create it by recording loans as deposits for borrowing clients. This process relies on a partial reserve system indicated by the cash ratio.
Today, most bank money is electronic and recorded on the books of financial institutions. Bank money is the most significant part of broad money in developed countries and can be converted into physical notes or used for cashless payments.
In most countries, most money is created as M1/M2 by commercial banks making loans. Contrary to some popular misconceptions, banks do not act merely as intermediaries lending out deposits that savers place with them. Instead, they create new loans and deposits independently of the central bank money (M0).
Functions of money
Money has a few important jobs in the economy. First, it makes it easier for people to buy and sell things. Money also helps us measure the value of goods and services. This is important for setting prices and keeping track of money. Additionally, money can be saved and used later. Lastly, money lets people buy things now and pay for them later. Overall, money is a very important tool for trade, stability, and growth in modern economies.
Properties of money
For money to effectively perform its functions as a medium of exchange, a unit of account, and a store of value, it must possess several fundamental properties:
Fungible
Fungibility means that individual units of money must be capable of mutual substitution, meaning they are interchangeable. Each unit of currency, whether a coin, bill or digital balance, must hold the same value as any other unit of the same amount. Money has uniformity, so one dollar bill is interchangeable with another, making it easy to use in transactions without needing to evaluate each unit separately.
Durable
Durability refers to the ability of money to withstand repeated use. Money must be made of materials that can endure physical wear and tear, ensuring it remains in circulation for a long time. Coins and banknotes are designed to be robust, while electronic money is stored digitally, reducing the risk of physical degradation. Durability is crucial for maintaining the value and utility of money over time.
Divisible
Divisibility means that money can be divided into smaller units to facilitate transactions of varying sizes. This property allows people to make purchases of both large and small items without difficulty. For instance, the dollar is divisible into cents, making it easy to price and pay for goods and services of any value. Divisibility ensures that money can accommodate a wide range of economic activities.
Portable
Portability refers to the ease with which money can be carried and transported. Adequate money must be lightweight and convenient, enabling people to conduct transactions wherever they go. Physical money, such as coins and banknotes, is designed to be portable, while electronic money can be transferred quickly and effortlessly through digital means. Portability enhances the practicality of money in everyday use.
Acceptable
Acceptability means that most people must recognize and accept money as a valid form of payment. For money to function effectively, there must be widespread trust and agreement in its value. This acceptance is typically established by government backing and legal tender laws, ensuring that money is recognized and used consistently within an economy.
Scarce
Scarcity refers to the limited supply of money in circulation. To maintain its value, money must be manageable. Central banks manage the money supply to ensure it remains scarce enough to preserve its purchasing power. If money were too plentiful, it would lose value due to inflation, undermining its effectiveness as a medium of exchange, unit of account, and store of value.
