What is a Derivative?
A derivative is an instrument whose value depends on, or is derived from, the value of another asset.
Examples: futures, forwards, swaps, options, exotics…
1
Why Derivatives Are ImportantDerivatives play a key role in transferring risks in the economy
The underlying assets include stocks, currencies, interest rates, commodities, debt instruments, electricity, insurance payouts, the weather, etc
Many financial transactions have embedded derivatives
The real options approach to assessing capital investment decisions has become widely accepted
2
How Derivatives Are Traded
On exchanges such as the Chicago Board Options Exchange
In the over-the-counter (OTC) market where traders working for banks, fund managers and corporate treasurers contact each other directly

Forward Price
The forward price for a contract is the delivery price that would be applicable to the contract if were negotiated today (i.e., it is the delivery price that would make the contract worth exactly zero)
The forward price may be different for contracts of different maturities (as shown by the table)

TerminologyThe party that has agreed to buy has what is termed a long position
The party that has agreed to sell has what is termed a short position

Example (page 5)
On May 24, 2010 the treasurer of a corporation enters into a long forward contract to buy £1 million in six months at an exchange rate of 1.4422
This obligates the corporation to pay $1,442,200 for £1 million on November 24, 2010
What are the possible outcomes?

Buy 100 oz. of gold @ US$1400/oz. in December

1. Gold: An Arbitrage Opportunity?
Suppose that:The spot price of gold is US$1,400The 1-year forward price of gold is US$1,500The 1-year US$ interest rate is 5% per
annum
Is there an arbitrage opportunity?
15
2. Gold: Another Arbitrage Opportunity?
Suppose that:- The spot price of gold is US$1,400- The 1-year forward price of gold is
US$1,400- The 1-year US$ interest rate is 5% per
annum
Is there an arbitrage opportunity?
16
The Forward Price of Gold (ignores the gold lease rate)
If the spot price of gold is S and the forward price for a contract deliverable in T years is F, then
F = S (1+r )T
where r is the 1-year (domestic currency) risk-free rate of interest.In our examples, S = 1400, T = 1, and r =0.05 so that
F = 1400(1+0.05) = 1470
