A derivative is a financial instrument that is derived from some other asset, index, event, value or condition (known as the underlying asset). Rather than trade or exchange the underlying asset itself, derivative traders enter into an agreement to exchange cash or assets over time based on the underlying asset. A simple example is a futures contract: an agreement to exchange the underlying asset at a future date. Derivatives are often highly leveraged, such that a small movement in the underlying value can cause a large difference in the value of the derivative. Derivatives can be used by investors to speculate and to make a profit if the value of the underlying moves the way they expect (e.g. moves in a given direction, stays in or out of a specified range, reaches a certain level). Alternatively, traders can use derivatives to hedge or mitigate risk in the underlying, by entering into a derivative contract whose value moves in the opposite direction to their underlying position and cancels part or all of it out. Derivatives are usually broadly categorised by:
[edit] Uses[edit] HedgingHedging is a technique designed to eliminate or reduce risk. Derivatives allow risk about the price of the underlying asset to be transferred from one party to another. For example, a wheat farmer and a miller could sign a futures contract to exchange a specified amount of cash for a specified amount of wheat in the future. Both parties have reduced a future risk: for the wheat farmer, the uncertainty of the price, and for the miller, the availability of wheat. However, there is still the risk that no wheat will be available because of events unspecified by the contract, like the weather, or that one party will renege on the contract. Although a third party, called a clearing house, insures a futures contract, not all derivatives are insured against counterparty risk. From another perspective, the farmer and the miller both reduce a risk and acquire a risk when they sign the futures contract: The farmer reduces the risk that the price of wheat will fall below the price specified in the contract and acquires the risk that the price of wheat will rise above the price specified in the contract (thereby losing additional income that he could have earned). The miller, on the other hand, acquires the risk that the price of wheat will fall below the price specified in the contract (thereby paying more in the future than he otherwise would) and reduces the risk that the price of wheat will rise above the price specified in the contract. In this sense, one party is the insurer (risk taker) for one type of risk, and the counterparty is the insurer (risk taker) for another type of risk. Hedging also occurs when an individual or institution buys an asset (like a commodity, a bond that has coupon payments, a stock that pays dividends, and so on) and sells it using a futures contract. The individual or institution has access to the asset for a specified amount of time, and then can sell it in the future at a specified price according to the futures contract. Of course, this allows the individual or institution the benefit of holding the asset while reducing the risk that the future selling price will deviate unexpectedly from the market's current assessment of the future value of the asset. Derivatives traders at the Chicago Board of Trade. Derivatives serve a legitimate business purpose. For example a corporation borrows a large sum of money at a specific interest rate.[1] The rate of interest on the loan resets every six months. the corporation is concerned that the rate of interest may be much higher in six months. The corporation could buy a forward rate agreement. A forward rate agreement is a contract to pay a fixed rate of interest six months after purchases on a notional sum of money.[2] If the interest rate after six months is above the contract rate the seller pays the difference to the FRA buyer, the corporation. If the rate is lower the corporation would pay the difference to the seller. The purchase of the FRA would serve to reduce the uncertainty concerning the rate increase and stabilize earnings. [edit] Speculation and arbitrageDerivatives can be used to acquire risk, rather than to insure or hedge against risk. Thus, some individuals and institutions will enter into a derivative contract to speculate on the value of the underlying asset, betting that the party seeking insurance will be wrong about the future value of the underlying asset. Speculators will want to be able to buy an asset in the future at a low price according to a derivative contract when the future market price is high, or to sell an asset in the future at a high price according to a derivative contract when the future market price is low. Individuals and institutions may also look for arbitrage opportunities, as when the current buying price of an asset falls below the price specified in a futures contract to sell the asset. Speculative trading in derivatives gained a great deal of notoriety in 1995 when Nick Leeson, a trader at Barings Bank, made poor and unauthorized investments in futures contracts. Through a combination of poor judgment, lack of oversight by the bank's management and by regulators, and unfortunate events like the Kobe earthquake, Leeson incurred a $1.3 billion loss that bankrupted the centuries-old institution.[3] [edit] Types of derivatives[edit] OTC and exchange-tradedBroadly speaking there are two distinct groups of derivative contracts, which are distinguished by the way they are traded in the market:
[edit] Common derivative contract typesThere are three major classes of derivatives:
More complex derivatives can be created by combining the elements of these basic types. For example, the holder of a swaption has the right, but not the obligation, to enter into a swap on or before a specified future date. [edit] ExamplesThe overall derivatives market has five major classes of underlying asset:
Some common examples of these derivatives are:
Other examples of underlying exchangeables are:
[edit] Cash flowThe payments between the parties may be determined by:
Some derivatives are the right to buy or sell the underlying security or commodity at some point in the future for a predetermined price. If the price of the underlying security or commodity moves into the right direction, the owner of the derivative makes money; otherwise, they lose money or the derivative becomes worthless. Depending on the terms of the contract, the potential gain or loss on a derivative can be much higher than if they had traded the underlying security or commodity directly. [edit] Valuation[edit] Market and arbitrage-free pricesTwo common measures of value are:
[edit] Determining the market priceFor exchange-traded derivatives, market price is usually transparent (often published in real time by the exchange, based on all the current bids and offers placed on that particular contract at any one time). Complications can arise with OTC or floor-traded contracts though, as trading is handled manually, making it difficult to automatically broadcast prices. In particular with OTC contracts, there is no central exchange to collate and disseminate prices. [edit] Determining the arbitrage-free priceThe arbitrage-free price for a derivatives contract is complex, and there are many different variables to consider. Arbitrage-free pricing is a central topic of financial mathematics. The stochastic process of the price of the underlying asset is often crucial. A key equation for the theoretical valuation of options is the Black–Scholes formula, which is based on the assumption that the cash flows from a European stock option can be replicated by a continuous buying and selling strategy using only the stock. A simplified version of this valuation technique is the binomial options model. [edit] CriticismsDerivatives are often subject to the following criticisms: [edit] Possible large lossesSee also: List of trading losses The use of derivatives can result in large losses because of the use of leverage, or borrowing. Derivatives allow investors to earn large returns from small movements in the underlying asset's price. However, investors could lose large amounts if the price of the underlying moves against them significantly. There have been several instances of massive losses in derivative markets, such as:
Members of President Clinton's Working Group on Financial Markets: Larry Summers, Alan Greenspan, Arthur Levitt, and Robert Rubin, have been criticized for torpedoing an effort to regulate the derivatives' markets, and thereby helping to bring down the financial markets in Fall 2008. President George W. Bush has also been criticized because he was President for 8 years preceding the 2008 meltdown and did nothing to regulate derivative trading. Bush has stated that deregulation was one of the core tenets of his political philosophy. [edit] Counter-party riskDerivatives (especially swaps) expose investors to counter-party risk. For example, suppose a person wanting a fixed interest rate loan for his business, but finding that banks only offer variable rates, swaps payments with another business who wants a variable rate, synthetically creating a fixed rate for the person. However if the second business goes bankrupt, it can't pay its variable rate and so the first business will lose its fixed rate and will be paying a variable rate again. If interest rates have increased, it is possible that the first business may be adversely affected, because it may not be prepared to pay the higher variable rate. Different types of derivatives have different levels of risk for this effect. For example, standardized stock options by law require the party at risk to have a certain amount deposited with the exchange, showing that they can pay for any losses; Banks who help businesses swap variable for fixed rates on loans may do credit checks on both parties. However in private agreements between two companies, for example, there may not be benchmarks for performing due diligence and risk analysis. [edit] Unsuitably high risk for small/inexperienced investorsDerivatives pose unsuitably high amounts of risk for small or inexperienced investors. Because derivatives offer the possibility of large rewards, they offer an attraction even to individual investors. However, speculation in derivatives often assumes a great deal of risk, requiring commensurate experience and market knowledge, especially for the small investor, a reason why some financial planners advise against the use of these instruments. Derivatives are complex instruments devised as a form of insurance, to transfer risk among parties based on their willingness to assume additional risk, or hedge against it.

(See Berkshire Hathaway Annual Report for 2002) [edit] Leverage of an economy's debtDerivatives massively leverage the debt in an economy, making it ever more difficult for the underlying real economy to service its debt obligations, thereby curtailing real economic activity, which can cause a recession or even depression. In the view of Marriner S. Eccles, U.S. Federal Reserve Chairman from November, 1934 to February, 1948, too high a level of debt was one of the primary causes of the 1920s-30s Great Depression. (See Berkshire Hathaway Annual Report for 2002) [edit] BenefitsNevertheless, the use of derivatives also has its benefits:
