The Size of the Market The market for derivative securities has become very large in recent years. The economic function of swaps and derivatives is to transfer risk from those who have it but who do not want to bear it to those who are willing to bear it for a fee.
Understanding Financial Derivatives
In this respect the derivatives market is much the same as the insurance industry. For example, a put option is insurance against the price of a stock falling. And, like the insurance industry, both the insuree and insurer are better off as a result of the transaction.
However, one usually does not refer to this insurance function as insuring; it is called hedging. Most of the transactions in these derivative securities is for speculation rather than for hedging.
Nevertheless the speculators serve a purpose. They provide the liquidity for the market to fulfill its social function of transferring risk.
A forwards swaps options part of the financial crisis of came as a result of businesses with risk involving their investment in home mortgages finding that that had not really transfered risk.
This happened because they dealt with counter parties who could not possibly fulfill the financial obligations they had incurred. Thus the businesses with a risk of mortgagee defaults had merely transformed that risk into counter-party risk. However because the businesses thought they had transfered the risk they more heavily invested in the risky securities.
Thus when mortgage defaults began to escalate the businesses found that in fact did not really have default insurance which meant their mortgage assets were worth far less than they had thought.
The derivative market, like the insurance industry, does involve gambling. The sizes of the bets in the financial markets however are vastly greater than in the gambling industry. The sizes of the involvement of banks and stock brokerage firms in derivative securities raises fears that there could be a catastrophic loss that would bring about a collapse of the financial system.

Other Derivative Securities There are many other contracts that businesses may find of interest. A cap is a contract that protects against rises in the interest rate beyond some limit. Likewise some businesses may want protection against a price drop beyond some level.
