Fiat money

The term fiat money is used to mean:

* any money declared by a government to be legal tender.
* state-issued money which is neither legally convertible to any other thing, nor fixed in value in terms of any objective standard.
* money without intrinsic value.

The term derives from the Latin fiat, meaning "let it be done", as the money is established by government decree. Where fiat money is used as currency, the term fiat currency is used. Today, most national currencies are fiat currencies, including the US dollar, the euro, and all other reserve currencies, and have been since the Nixon Shock of 1971.

Banknote

A banknote (often known as a bill, paper money or simply a note) is a kind of negotiable instrument, a promissory note made by a bank payable to the bearer on demand, used as money, and in many jurisdictions is legal tender. Along with coins, banknotes make up the cash or bearer forms of all modern fiat money. With the exception of non-circulating high-value or precious metal commemorative issues, coins are used for lower valued monetary units, while banknotes are used for higher values.

Security (finance)

A security is a fungible, negotiable instrument representing financial value. Securities are broadly categorized into debt securities (such as banknotes, bonds and debentures) and equity securities, e.g., common stocks; and derivative contracts, such as forwards, futures, options and swaps. The company or other entity issuing the security is called the issuer. A country's regulatory structure determines what qualifies as a security. For example, private investment pools may have some features of securities, but they may not be registered or regulated as such if they meet various restrictions.

Securities may be represented by a certificate or, more typically, "non-certificated", that is in electronic or "book entry" only form. Certificates may be bearer, meaning they entitle the holder to rights under the security merely by holding the security, or registered, meaning they entitle the holder to rights only if he or she appears on a security register maintained by the issuer or an intermediary. They include shares of corporate stock or mutual funds, bonds issued by corporations or governmental agencies, stock options or other options, limited partnership units, and various other formal investment instruments that are negotiable and fungible.

Intrinsic value (finance)

In finance, intrinsic value refers to the value of a security which is intrinsic to or contained in the security itself. It is also frequently called fundamental value. It is ordinarily calculated by summing the future income generated by the asset, and discounting it to the present value.

Economic bubble

An economic bubble (sometimes referred to as a speculative bubble, a market bubble, a price bubble, a financial bubble, a speculative mania or a balloon) is “trade in high volumes at prices that are considerably at variance with intrinsic values”. It could also be described as a trade in products or assets with inflated values.

While some economists deny that bubbles occur, the cause of bubbles remains a challenge to those who are convinced that asset prices often deviate strongly from intrinsic values.

While many explanations have been suggested, it has been recently shown that bubbles appear even without uncertainty, speculation, or bounded rationality. It has also been suggested that bubbles might ultimately be caused by processes of price coordination or emerging social norms. Because it is often difficult to observe intrinsic values in real-life markets, bubbles are often conclusively identified only in retrospect, when a sudden drop in prices appears. Such a drop is known as a crash or a bubble burst. Both the boom and the bust phases of the bubble are examples of a positive feedback mechanism, in contrast to the negative feedback mechanism that determines the equilibrium price under normal market circumstances. Prices in an economic bubble can fluctuate erratically, and become impossible to predict from supply and demand alone.

Depression

In economics, a depression is a sustained, long-term downturn in economic activity in one or more economies. It is a more severe downturn than a recession, which is seen by economists as part of a normal business cycle.

Considered a rare and extreme form of recession, a depression is characterized by its length, and by abnormally large increases in unemployment, falls in the availability of credit— often due to some kind of banking/financial crisis, shrinking output and investment, large number of bankruptcies—including sovereign debt defaults, significantly reduced amounts of trade and commerce—especially international, as well as highly volatile relative currency value fluctuations—most often due to devaluations. Price deflation, financial crises and bank failures are also common elements of a depression.

Recession

In economics, a recession is a business cycle contraction, a general slowdown in economic activity over a period of time longer than a few months. During recessions, many macroeconomic indicators vary in a similar way. Production, as measured by Gross Domestic Product (GDP), employment, investment spending, capacity utilization, household incomes, business profits and inflation all fall during recessions; while bankruptcies and the unemployment rate rise.

Recessions generally occur when there is a widespread drop in spending often following an adverse supply shock or the bursting of an economic bubble. Governments usually respond to recessions by adopting expansionary macroeconomic policies, such as increasing money supply, increasing government spending and decreasing taxation.

Inflation

In economics, inflation is a rise in the general level of prices of goods and services in an economy over a period of time. When the general price level rises, each unit of currency buys fewer goods and services. Consequently, inflation also reflects an erosion in the purchasing power of money – a loss of real value in the internal medium of exchange and unit of account in the economy. A chief measure of price inflation is the inflation rate, the annualized percentage change in a general price index (normally the Consumer Price Index) over time.

Inflation's effects on an economy are various and can be simultaneously positive and negative. Negative effects of inflation include a decrease in the real value of money and other monetary items over time, uncertainty over future inflation may discourage investment and savings, and high inflation may lead to shortages of goods if consumers begin hoarding out of concern that prices will increase in the future. Positive effects include ensuring central banks can adjust nominal interest rates (intended to mitigate recessions), and (as the rate of inflation rises) debt relief by reducing the real level of debt.[citation needed]

Economists generally agree that high rates of inflation and hyperinflation are caused by an excessive growth of the money supply. Views on which factors determine low to moderate rates of inflation are more varied. Low or moderate inflation may be attributed to fluctuations in real demand for goods and services, or changes in available supplies such as during scarcities, as well as to growth in the money supply. However, the consensus view is that a long sustained period of inflation is caused by money supply growing faster than the rate of economic growth.

Today, most mainstream economists favor a low steady rate of inflation. Low (as opposed to zero or negative) inflation may reduce the severity of economic recessions by enabling the labor market to adjust more quickly in a downturn, and reduce the risk that a liquidity trap prevents monetary policy from stabilizing the economy. The task of keeping the rate of inflation low and stable is usually given to monetary authorities. Generally, these monetary authorities are the central banks that control the size of the money supply through the setting of interest rates, through open market operations, and through the setting of banking reserve requirements.

Interest rate

An interest rate is the rate at which interest is paid by a borrower for the use of money that they borrow from a lender. For example, a small company borrows capital from a bank to buy new assets for their business, and in return the lender receives interest at a predetermined interest rate for deferring the use of funds and instead lending it to the borrower. Interests rates are fundamental to a capitalist society[dubious – discuss]. Interest rates are normally expressed as a percentage rate over the period of one year.

Interest rates targets are also a vital tool of monetary policy and are taken into account when dealing with variables like investment, inflation, and unemployment.

Economic expansion

An economic expansion is an increase in the level of economic activity, and of the goods and services available in the market place. It is a period of economic growth as measured by a rise in real GDP. The explanation of such fluctuations in aggregate economic activity is one of the primary concerns of macroeconomics.

Typically an economic expansion is marked by an upturn in production and utilization of resources. Economic recovery and prosperity are two successive phases of expansion. It may be caused by factors external to the economy, such as weather conditions or technical change, or by factors internal to the economy, such as fiscal policies, monetary policies, the availability of credit, interest rates, regulatory policies or other impacts on producer incentives. Global conditions may influence the levels of economic activity in various countries.

Economic contraction and expansion relate to the overall output of all goods and services, while the terms inflation and deflation refer to increasing and decreasing prices of commodities, goods and services in relation to the value of money.

Business cycle

The term business cycle (or economic cycle) refers to economy-wide fluctuations in production or economic activity over several months or years. These fluctuations occur around a long-term growth trend, and typically involve shifts over time between periods of relatively rapid economic growth (expansion or boom), and periods of relative stagnation or decline (contraction or recession).

These fluctuations are often measured using the growth rate of real gross domestic product. Despite being termed cycles, most of these fluctuations in economic activity do not follow a mechanical or predictable periodic pattern.

Option (finance)

In finance, an option is a derivative financial instrument that establishes a contract between two parties concerning the buying or selling of an asset at a reference price during a specified time frame. During this time frame, the buyer of the option gains the right, but not the obligation, to engage in some specific transaction on the asset, while the seller incurs the obligation to fulfill the transaction if so requested by the buyer. The price of an option derives from the value of an underlying asset (commonly a stock, a bond, a currency or a futures contract) plus a premium based on the time remaining until the expiration of the option. Other types of options exist, and options can in principle be created for any type of valuable asset.

An option which conveys the right to buy something is called a call; an option which conveys the right to sell is called a put. The price specified at which the underlying may be traded is called the strike price or exercise price. The process of activating an option and thereby trading the underlying at the agreed-upon price is referred to as exercising it. Most options have an expiration date. If the option is not exercised by the expiration date, it becomes void and worthless.

In return for granting the option, called writing the option, the originator of the option collects a payment, the premium, from the buyer. The writer of an option must make good on delivering (or receiving) the underlying asset or its cash equivalent, if the option is exercised.

An option can usually be sold by its original buyer to another party. Many options are created in standardized form and traded on an anonymous options exchange among the general public, while other over-the-counter options are customized to the desires of the buyer on an ad hoc basis, usually by an investment bank.

Commodity

A commodity is a good for which there is demand, but which is supplied without qualitative differentiation across a market. Commodities are often substances that come out of the earth and maintain roughly a universal price. A commodity is fungible, that is, equivalent no matter who produces it. Examples are petroleum, notebook paper, milk, and copper. The price of copper is universal, and fluctuates daily based on global supply and demand. Stereo systems, on the other hand, have many aspects of product differentiation, such as the brand, the user interface, the perceived quality etc. And, the more valuable a stereo is perceived to be, the more it will cost.

In contrast, one of the characteristics of a commodity good is that its price is determined as a function of its market as a whole. Well-established physical commodities have actively traded spot and derivative markets. Generally, these are basic resources and agricultural products such as iron ore, crude oil, coal, ethanol, salt, sugar, coffee beans, soybeans, aluminum, copper, rice, wheat, gold, silver, palladium, and platinum. Soft commodities are goods that are grown, while hard commodities are the ones that are extracted through mining.

There is another important class of energy commodities which includes electricity, gas, coal and oil. Electricity has the particular characteristic that it is either impossible or uneconomical to store, hence, electricity must be consumed as soon as it is produced.

Commoditization occurs as a goods or services market loses differentiation across its supply base, often by the diffusion of the intellectual capital necessary to acquire or produce it efficiently. As such, goods that formerly carried premium margins for market participants have become commodities, such as generic pharmaceuticals and silicon chips.

Gold standard

The gold standard is a monetary system in which the standard economic unit of account is a fixed weight of gold. There are distinct kinds of gold standard. First, the gold specie standard is a system in which the monetary unit is associated with circulating gold coins, or with the unit of value defined in terms of one particular circulating gold coin in conjunction with subsidiary coinage made from a lesser valuable metal.

Similarly, the gold exchange standard typically involves the circulation of only coins made of silver or other metals, but where the authorities guarantee a fixed exchange rate with another country that is on the gold standard. This creates a de facto gold standard, in that the value of the silver coins has a fixed external value in terms of gold that is independent of the inherent silver value. Finally, the gold bullion standard is a system in which gold coins do not circulate, but in which the authorities have agreed to sell gold bullion on demand at a fixed price in exchange for the circulating currency.

Reserve currency

A reserve currency, or anchor currency, is a currency which is held in significant quantities by many governments and institutions as part of their foreign exchange reserves. It also tends to be the international pricing currency for products traded on a global market, and commodities such as oil, gold, etc.

This permits the issuing country to purchase the commodities at a marginally lower rate than other nations, which must exchange their currencies with each purchase and pay a transaction cost. For major currencies, this transaction cost is negligible with respect to the price of the commodity. It also permits the government issuing the currency to borrow money at a better rate, as there will always be a larger market for that currency than others.

Nixon Shock

The Nixon Shock was a series of economic measures taken by U.S. President Richard Nixon in 1971 including unilaterally canceling the direct convertibility of the United States dollar to gold that essentially ended the existing Bretton Woods system of international financial exchange.

Bretton Woods system

The Bretton Woods system of monetary management established the rules for commercial and financial relations among the world's major industrial states in the mid 20th century. The Bretton Woods system was the first example of a fully negotiated monetary order intended to govern monetary relations among independent nation-states.

Preparing to rebuild the international economic system as World War II was still raging, 730 delegates from all 44 Allied nations gathered at the Mount Washington Hotel in Bretton Woods, New Hampshire, United States, for the United Nations Monetary and Financial Conference. The delegates deliberated upon and signed the Bretton Woods Agreements during the first three weeks of July 1944.

Setting up a system of rules, institutions, and procedures to regulate the international monetary system, the planners at Bretton Woods established the International Monetary Fund (IMF) and the International Bank for Reconstruction and Development (IBRD), which today is part of the World Bank Group. These organizations became operational in 1945 after a sufficient number of countries had ratified the agreement.

The chief features of the Bretton Woods system were an obligation for each country to adopt a monetary policy that maintained the exchange rate of its currency within a fixed value—plus or minus one percent—in terms of gold and the ability of the IMF to bridge temporary imbalances of payments.

On August 15, 1971, the United States unilaterally terminated convertibility of the dollar to gold. This action, referred to as the Nixon shock, created the situation in which the United States dollar became the sole backing of currencies and a reserve currency for the member states.

Forex

The foreign exchange market (forex, FX, or currency market) is a worldwide decentralized over-the-counter financial market for the trading of currencies. Financial centers around the world function as anchors of trading between a wide range of different types of buyers and sellers around the clock, with the exception of weekends. The foreign exchange market determines the relative values of different currencies.

The primary purpose of the foreign exchange is to assist international trade and investment, by allowing businesses to convert one currency to another currency. For example, it permits a US business to import British goods and pay Pound Sterling, even though the business's income is in US dollars. It also supports speculation, and facilitates the carry trade, in which investors borrow low-yielding currencies and lend (invest in) high-yielding currencies, and which (it has been claimed) may lead to loss of competitiveness in some countries.

Real interest rate

The "real interest rate" is approximately the nominal interest rate minus the inflation rate (see Fisher equation and below for exact equation). It is the rate of interest an investor expects to receive after subtracting inflation. This is not a single number, as different investors have different expectations of future inflation. If, for example, an investor were able to lock in a 5% interest rate for the coming year and anticipated a 2% rise in prices, he would expect to earn a real interest rate of 3%.

Since the inflation rate over the course of a loan is not known initially, volatility in inflation represents a risk to both the lender and the borrower.

Negative Interest Rates

If there is a negative real interest rate, it means that the inflation rate is greater than the interest rate. If the Federal funds rate is 2% and the inflation rate is 10%, then the borrower would gain 7.27% of every dollar borrowed.
