Types of money

In economics, money is a broad term that refers to any instrument that can be used in the resolution of debt. However, not all money is created equal. One theoretician, Ludwig von Mises, argued for the importance of distinguishing between three types of money: commodity money, fiat money, and credit money. Each carries different economic strengths and liabilities - a point driven home in his book The Theory of Money and Credit. Modern monetary theory also distinguishes between different types of money, using a categorization system that focuses on the liquidity of money. Commodity money Commodity money is any money that is both used as a general purpose medium of exchange and as a tradable commodity in its own right.[2] Commodity based currencies are often viewed as more stable, but this is not always the case. The value of a commodity based currency as a medium of exchange depends on its supply relative to other goods and services available in the economy. Historically, gold, silver and other metals commonly used in commodity based monetary systems have been subject to regular and sometimes extraordinary fluctuations in purchasing power. This not only damages its stability as a medium of exchange; it also reduces its effectiveness as a store of value. In the 1500 and 1600's huge quantities of gold and even larger amounts of silver were discovered in the New World and brought back to Europe for conversion into coin, the purchasing power of those coins fell by 60% to 80%, i.e. prices of commodities rose, because the supply of goods for sale did not keep pace with the increased supply of money.[3] In addition, the relative value of silver to gold shifted dramatically downward.[4] More recently, from 1980 to 2001, gold was a particularly poor store of value, as gold prices dropped from a high of $850/oz. to a low of $255/oz. The advantage of gold and silver, however, lies in the fact that, unlike fiat paper currency, the supply cannot be increased arbitrarily by a central bank. It is also possible for the trading value of a commodity money to be greater than its value as a medium of exchange. When this happens people will often start melting down coins and reselling the metal used to make them. This has happened periodically in the United States, eventually causing it to move away from pure silver nickels and pure copper pennies.[citation needed] Shipping coins from one jurisdiction to another so that they could be reminted was sometimes a lucrative trade before the advent of trusted paper money.[citation needed] Commodity money's ability to function as a store of value is also limited by its very nature. Copper and tin risk rust and corrosion. Gold and silver are soft metals that can lose weight through scratches and abrasions. Stability aside, commodity based currencies are limiting in a rapidly growing or very active economy. The supply of money in an economy must be equal or greater than the volume of trade. If commodities are used as money, then the money supply must equal the total amount of goods and services sold. In a large economy, the volume of trade can easily outstrip the supply of any one commodity. This problem is compounded by the fact that money also serves as a store of value. This encourages hoarding and takes the commodity money out circulation, reducing the supply. The supply of circulating commodity currency is further reduced by the fact that commodity moneys also have competing non-monetary uses. For example, gold and silver is used in jewelery and nickel and copper have important industrial uses. Commodity based currencies also limit the geographic extent of the trading market. To make large purchases either a large volume or a high weight or both of the commodity must be transported to the seller. The cost of transportation of the currency raises the transaction cost and makes long distance sales less attractive. Fiat money Fiat money is any money whose value is determined by legal means rather than the relative availability of goods and services. Fiat money may be symbolic of a commodity or government promises.[2] Fiat money provides solutions to several limitations of commodity money. Depending on the laws, there may be little or no need to physically transport the money - an electronic exchange may be sufficient. Its sole use is as a medium of exchange so its supply is not limited by competing alternate uses. It can be printed without limit, so there is no limit on trade volumes. Fiat money, especially in the form of paper or coins, can be easily damaged or destroyed. However, it has has an advantage over commodity money in that the same laws that created the money can also define rules for its replacement in case of damage or destruction. For example, the US government will replace mutilated paper money if at least half of the bill can be reconstructed.[5]. By contrast commodity money is gone for good. Paper money is especially vulnerable to everyday hazards: from fire, water, termites, and simple wear and tear. Money in the form of minted coins is sometimes destroyed by children placing it on railroad tracks or in amusement park machines that restamp it. In order to reduce replacement costs, many countries are converting to plastic bills. For example, Mexico has changed its twenty and fifty pesos notes, Singapore its $2 and $10 bills, Malaysia with $1,$5,$10,$50 and $100, and Australia and New Zealand their $5, $10, $20, $50 and $100 to plastic for the increased durability. Some of the benefits of fiat money can be a double-edged sword. For example, if the amount of money in active circulation outstrips the available goods and services for sale, the effect can be inflationary. This can easily happen if governments print money without attention to the level of economic activity or counterfeiters are allowed to flourish. Perhaps the biggest criticism of paper money relates to the fact that its stability is highly dependent on the stability of the legal system backing the currency. Should the legal system fail, so would the currency that depends on it. Credit money Credit money is any claim against a physical or legal person that can be used for the purchase of goods and services[2]. Credit money differs from commodity and fiat money in two important ways: It is not payable on demand and there is some element of risk that the real value upon fulfillment of the claim will not be equal to real value expected at the time of purchase[2]. This risk comes about in two ways and affects both buyer and seller. First it is a claim and the claimant may default (not pay). High levels of default have destructive supply side effects. If manufacturers and service providers do not receive payment for the goods they produce, they will not have the resources to buy the labor and materials needed to produce new goods and services. This reduces supply, increases prices and raises unemployment, possibly triggering a period of stagflation. In extreme cases, widespread defaults can cause a lack of confidence in lending institutions and lead to economic depression. For example, abuse of credit arrangements is considered one of the significant causes of the Great Depression of the 1930s. [6] The second source of risk is time. Credit money is a promise of future payment. If the interest rate on the claim fails to compensate for the combined impact of the inflation (or deflation) rate and the time value of money, the seller will receive less real value than anticipated. If the interest rate on the claim overcompensates, the buyer will pay more than expected. Over the last two centuries, credit money has steadily risen as the main source of money creation, progressively replacing first commodity then fiat money. The main problem with credit money is that its supply moves in line with credit booms and bust. When lenders are optimistic (notably when the debt level is low), they increase their lendings activity, thus creating new money and triggering inflation, when they are pessimistic (for instance because the debt level is perceived as so high that defaults can only follow), they reduce their lending activities, bankrupcies and deflation follows. Money supply The money supply is the amount of money available within a specific economy available for purchasing goods or services. The supply in the US is usually considered as four escalating categories M0, M1, M2 and M3. The categories grow in size with M3 representing all forms of money (including credit) and M0 being just base money (coins, bills, and central bank deposits). M0 is also money that can satisfy private banks' reserve requirements. In the US, the Federal Reserve is responsible for controlling the money supply, while in the Euro area the respective institution is the ECB. Other central banks with significant impact on global finances are the Bank of Japan, People's Bank of China and the Bank of England. When gold is used as money, the money supply can grow in either of two ways. First, the money supply can increase as the amount of gold increases by new gold mining at about 2% per year, but it can also increase more during periods of gold rushes and discoveries, such as when Columbus discovered the new world and brought gold back to Spain, or when gold was discovered in California in 1848. This kind of increase helps debtors, and causes inflation, as the value of gold goes down. Second, the money supply can increase when the value of gold goes up. This kind of increase in the value of gold helps savers and creditors and is called deflation, where items for sale are increasingly less expensive in terms of gold. Deflation was the more typical situation for over a century when gold and credit money backed by gold were used as money in the US from 1792 to 1913. Monetary policy Monetary policy is the process by which a government, central bank, or monetary authority manages the money supply to achieve specific goals. Usually the goal of monetary policy is to accommodate economic growth in an environment of stable prices. For example, it is clearly stated in the Federal Reserve Act that the Board of Governors and the Federal Open Market Committee should seek “to promote effectively the goals of maximum employment, stable prices, and moderate long-term interest rates.” [7] A failed monetary policy can have significant detrimental effects on an economy and the society that depends on it. These include hyperinflation, stagflation, recession, high unemployment, shortages on imported goods, inability to export goods, and even total monetary collapse and the adoption of a much less efficient barter economy. This happened in Russia, for instance, after the fall of the Soviet Union. Governments and central banks have taken both regulatory and free market approaches to monetary policy. Some of the various tools used to control the money supply include: currency purchases or sales increasing or lowering government spending increasing or lowering government borrowing changing the rate at which the government loans or borrows money manipulation of exchange rates taxation or tax breaks on imports or exports of capital into a country raising or lowering bank reserve requirements regulation or prohibition of private currencies For many years much of monetary policy was influenced by an economic theory known as monetarism. Monetarism is an economic theory which argues that management of the money supply should be the primary means of regulating economic activity. The stability of the demand for money prior to the 1980s was a key finding of Milton Friedman and Anna Schwartz [8] supported by the work of David Laidler[9], and many others. Technical, institutional, and legal changes changed the nature of the demand for money during the 1980s and the influence of monetarism has since decreased.
