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, different types of money have different economic strengths and liabilities. Theoretician Ludwig von Mises made that point in his book The Theory of Money and Credit, and he argued for the importance of distinguishing among three types of money: commodity money, fiat money, and credit money. Modern monetary theory also distinguishes among 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.[5] An example is coins made of precious metal.
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 1500s and 1600s 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. As a result, the purchasing power of those coins fell by 60% to 80%, i.e. the prices of goods rose, because the supply of goods did not keep pace with the increased supply of money.[6] In addition, the relative value of silver to gold shifted dramatically downward.[7] Such discoveries of huge sources of gold or silver are a thing of the past, and lend to their supply stability. More recently, from 1980 to 2001, gold was a particularly poor store of value, as gold prices dropped from a high of $850/oz. ($27.30 /g) to a low of $255/oz. ($8.20 /g), although this figure is now back to almost $750 per ounce as of late 2007.[8] It should be noted that gold was not a currency at this time, and was fluctuating due to its status as a final store of value — that is, the price never goes to zero as fiat currencies may (in theory). 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 governments attempt to fix exchange rates between different commodity monies. 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, but this is nothing by comparison to fiat currencies, where billions of dollars can be injected ("printed") into the market within moments.
Stability aside, commodity-based currencies may have a tendency to restrain growth in a very active economy. For example, in order to maintain the price level, the supply of money in an any economy must be equal or greater than the volume of goods and services produced. If commodities are used as money, then the total production can easily outstrip the supply of those commodities, which leads to price deflation. The lower prices of goods would signal to their producers to reduce the supply of goods, hence restoring the price level. As such, production within commodity-based economies tends to be limited by the supply of the commodity currency.[citation needed]
This problem is compounded by the fact that money also serves as a store of value. This encourages hoarding (in other circumstances known as "saving") and takes the commodity money out of 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 are used in jewelery, and nickel and copper have important industrial uses.
Commodity currencies may 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.
Representative money
Representative money refers to money that consists of token coins, other physical tokens such as certificates, and even non-physical "digital certificates" (authenticated digital transactions) that can be reliably exchanged for a fixed quantity of a commodity such as gold, silver or potentially water, oil or food. Representative money thus stands in direct and fixed relation to the commodity which backs it. This is to be distinguished from commodity money which is actually composed of a real and intrically valuable physical commodity.
Credit money
Credit money is any claim against a physical or legal person that can be used for the purchase of goods and services[5]. Credit money differs from commodity and fiat money in two ways: It is not payable on demand (although in the case of fiat money, "demand payment" is a purely symbolic act since all that can be demanded is other types of fiat currency) 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[5].
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.[9]
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 and then representative money. In many cases credit money has been converted to fiat money (see below), as governments have backed certain private credit instruments (first banknotes from central banks, then later certain types of deposits to banks), thus converting central banknotes to legal tender, and other types of notes (deposit certificates of less than a certain value) to a status not very different from fiat money, since they are backed by the power of the central government to redeem eventually with tax collection.
A particular problem with credit money is that its supply moves in line with credit/business cycles (colloquially: "booms" and "busts"). When lenders are optimistic (notably when the debt level is low), they increase their lending activity, thus creating new money. This may also trigger inflation and bull markets. When creditors are pessimistic (for instance, when debt level is perceived as too high, or unwise lending activity in the past has resulted in situations where defaults are expected to follow), then creditors reduce their lending activity and money becomes "tight" or "illiquid." Bankruptcies and market recessions (so-called bear markets) then follow.
Fiat money
Fiat money is any money whose value is determined by legal means, rather than the strict availability of goods and services which are named on the representative note.
Fiat money is created when a type of credit money (typically notes from a central bank, such as the Federal Reserve System in the U.S.) is declared by a government act (fiat) to be acceptable and officially-recognized payment for all debts, both public and private. Fiat money may thus be symbolic of a commodity or a government promise, though not a completely specified amount of either of these. Fiat money is thus not technically fungible or tradable directly for fixed quantities of anything, except more of the same government's fiat money. Fiat moneys usually trade against each other in value in an international market, as with other goods. An exception to this is when currencies are locked to each other, as explained below. Many but not all fiat moneys are accepted on the international market as having value. Those that are trade indirectly against any internationally available goods and services [5]. Thus the number of U.S. dollars or Japanese yen which are equivalent to each other, or to a gram of gold metal, are all market decisions which change from moment to moment on a daily basis. Occasionally, a country will peg the value of its fiat money to that of the fiat money of a larger economy: for example the Belize dollar trades in fixed proportion (at 2:1) to the U.S. dollar, so there is no floating value ratio of the two currencies.
Representative, credit, and fiat money all provide 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. Other types of moneys have as their sole use to be medium of exchange, so their supply is not limited by competing alternate uses. Credit and fiat monies can be created without limit in theory, so there is no limit on trade volumes.
Fiat money, if physically represented in the form of currency (paper or coins) can be easily damaged or destroyed. However, here fiat money has an advantage over representative or 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 U.S. government will replace mutilated federal reserve notes (U.S. fiat money) if at least half of the physical note can be reconstructed, or if it can be otherwise proven to have been destroyed. [10]. By contrast, commodity money which has been destroyed or lost is gone.
Paper currency is especially vulnerable to everyday hazards: from fire, water, termites, and simple wear and tear. Currency in the form of minted coins is more durable but a significant portion is simply lost in everyday use. In order to reduce replacement costs, many countries are converting to plastic currency. For example, Mexico has changed its twenty and fifty peso notes, Singapore its $2, $5, $10 and $50 bills, Malaysia with RM5 bill, and Australia and New Zealand their $5, $10, $20, $50 and $100 to plastic, both for the increased durability and because plastic may be easily specifically constructed for each denomination, thus making it impossible for counterfeiters to "lift" or raise the value of a bill by using the material of a bill of lesser value as a primary source to make a counterfeit note of higher value.
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 if successful counterfeiters flourish.
A criticism of credit and fiat moneys relates to the fact that their stabilities are highly dependent on the stability of the legal system backing the currency: should the legal system fail, so will the value of any type of money that depends on it. However, this situation is typical of the maintainance of the value of any promisory note system: if a guarantor creates money or wealth by means of any legal promise to provide goods or services in the future (as is the case with both credit and fiat type moneys), then any failure of a legal system which backs up the rights of the debt-holder to collect on the promise, will act to jeoparize the value of future promises.
Money supply
The money supply is the amount of money 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 European Central Bank. 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 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.
History of money
The first golden coins in history were coined by Lydian king Croesus, around 560 BC. The first Greek coins were made initially of copper, then of iron because copper and iron were powerful materials used to make weapons. Pheidon king of Argos, around 700 BC, changed the coins from iron to a rather useless and ornamental metal, silver, and, according to Aristotle, dedicated some of the remaining iron coins (which were actually iron sticks) to the temple of Hera[1]. King Pheidon coined the silver coins at Aegina, at the temple of the goddess of wisdom and war Athena the Aphaia (the vanisher), and engraved the coins with a Chelone, which is to this day as a symbol of capitalism. Chelone coins[2] were the first medium of exchange that was not backed by a real value good. They were widely accepted and used as the international medium of exchange until the days of Peloponnesian War, when the Athenian Drachma replace them. According other fables, inventors of money were Demodike (or Hermodike) of Kymi (the wife of Midas), Lykos (son of Pandion II and ancestor of the Lycians) and Erichthonius, the Lydians or the Naxians.
