Derivative (finance)
In finance, a derivative is a contract that derives its value from the performance of an underlying entity. This underlying entity can be an asset, index, or interest rate, and is often simply called the underlying.[1][2] Derivatives can be used for a number of purposes, including insuring against price movements (hedging), increasing exposure to price movements for speculation, or getting access to otherwise hard-to-trade assets or markets.[3]
This article is about the term as used in finance. For the calculus term, see Derivative. For other uses, see Derivative (disambiguation).
Some of the more common derivatives include forwards, futures, options, swaps, and variations of these such as synthetic collateralized debt obligations and credit default swaps. Most derivatives are traded over-the-counter (off-exchange) or on an exchange such as the Chicago Mercantile Exchange, while most insurance contracts have developed into a separate industry. In the United States, after the financial crisis of 2007–2009, there has been increased pressure to move derivatives to trade on exchanges.
Derivatives are one of the three main categories of financial instruments, the other two being equity (i.e., stocks or shares) and debt (i.e., bonds and mortgages). The oldest example of a derivative in history, attested to by Aristotle, is thought to be a contract transaction of olives, entered into by ancient Greek philosopher Thales, who made a profit in the exchange.[4] However, Aristotle did not define this arrangement as a derivative but as a monopoly (Aristotle's Politics, Book I, Chapter XI). Bucket shops, outlawed in 1936 in the US, are a more recent historical example.
Size of market[edit]
To give an idea of the size of the derivative market, The Economist has reported that as of June 2011, the over-the-counter (OTC) derivatives market amounted to approximately $700 trillion, and the size of the market traded on exchanges totaled an additional $83 trillion.[9] For the fourth quarter 2017 the European Securities Market Authority estimated the size of European derivatives market at a size of €660 trillion with 74 million outstanding contracts.[10]
However, these are "notional" values, and some economists say that these aggregated values greatly exaggerate the market value and the true credit risk faced by the parties involved. For example, in 2010, while the aggregate of OTC derivatives exceeded $600 trillion, the value of the market was estimated to be much lower, at $21 trillion. The credit-risk equivalent of the derivative contracts was estimated at $3.3 trillion.[11]
Still, even these scaled-down figures represent huge amounts of money. For perspective, the budget for total expenditure of the United States government during 2012 was $3.5 trillion,[12] and the total current value of the U.S. stock market is an estimated $23 trillion.[13] Meanwhile, the global annual Gross Domestic Product is about $65 trillion.[14]
At least for one type of derivative, credit default swaps (CDS), for which the inherent risk is considered high , the higher, nominal value remains relevant. It was this type of derivative that investment magnate Warren Buffett referred to in his famous 2002 speech in which he warned against "financial weapons of mass destruction".[15] CDS notional value in early 2012 amounted to $25.5 trillion, down from $55 trillion in 2008.[16]
