- 4. Derivatives Markets Exchange traded Traditionally exchanges have used the open-outcry system, but increasingly they are switching to electronic trading Contracts are standard there is virtually no credit risk Over-the-counter (OTC) A computer- and telephone-linked network of dealers at financial institutions, corporations, and fund managers Contracts can be non-standard and there is some small amount of credit risk
- 5. Size of OTC and Exchange Markets (Figure 1.1, Page 3) Source: Bank for International Settlements. Chart shows total principal amounts for OTC market and value of underlying assets for exchange market
- 6. Ways Derivatives are Used To hedge risks To speculate (take a view on the future direction of the market) To lock in an arbitrage profit To change the nature of a liability To change the nature of an investment without incurring the costs of selling one portfolio and buying another
- 7. Forward Contracts Forward contracts are similar to futures except that they trade in the over-the-counter market Forward contracts are particularly popular on currencies and interest rates

- 9. 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
- 10. Terminology The 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
- 11. Example (page 4) On June 3, 2003 the treasurer of a corporation enters into a long forward contract to buy £1 million in six months at an exchange rate of 1.6100 This obligates the corporation to pay $1,610,000 for £1 million on December 3, 2003 What are the possible outcomes?

- 16. Examples of Futures Contracts Agreement to: buy 100 oz. of gold @ US$400/oz. in December (NYMEX) sell £62,500 @ 1.5000 US$/£ in March (CME) sell 1,000 bbl. of oil @ US$20/bbl. in April (NYMEX)
- 17. 1. Gold: An Arbitrage Opportunity? Suppose that: The spot price of gold is US$300 The 1-year forward price of gold is US$340 The 1-year US$ interest rate is 5% per annum Is there an arbitrage opportunity?
- 18. 2. Gold: Another Arbitrage Opportunity? Suppose that: The spot price of gold is US$300 The 1-year forward price of gold is US$300 The 1-year US$ interest rate is 5% per annum Is there an arbitrage opportunity?
- 19. The Forward Price of Gold 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 = 300, T = 1, and r =0.05 so that F = 300(1+0.05) = 315
- 20. 1. Oil: An Arbitrage Opportunity? Suppose that: The spot price of oil is US$19 The quoted 1-year futures price of oil is US$25 The 1-year US$ interest rate is 5% per annum The storage costs of oil are 2% per annum Is there an arbitrage opportunity ?
- 21. 2. Oil: Another Arbitrage Opportunity? Suppose that: The spot price of oil is US$19 The quoted 1-year futures price of oil is US$16 The 1-year US$ interest rate is 5% per annum The storage costs of oil are 2% per annum Is there an arbitrage opportunity ?

- 27. Types of Traders Hedgers Speculators Arbitrageurs Some of the largest trading losses in derivatives have occurred because individuals who had a mandate to be hedgers or arbitrageurs switched to being speculators (See for example Barings Bank, Business Snapshot 1.2, page 15)
- 28. Hedging Examples (pages 10-11) A US company will pay £10 million for imports from Britain in 3 months and decides to hedge using a long position in a forward contract An investor owns 1,000 Microsoft shares currently worth $28 per share. A two-month put with a strike price of $27.50 costs $1. The investor decides to hedge by buying 10 contracts
- 29. Value of Microsoft Shares with and without Hedging (Fig 1.4, page 11)
- 30. Speculation Example An investor with $4,000 to invest feels that Amazon.com’s stock price will increase over the next 2 months. The current stock price is $40 and the price of a 2-month call option with a strike of 45 is $2 What are the alternative strategies?
- 31. Arbitrage Example A stock price is quoted as £100 in London and $172 in New York The current exchange rate is 1.7500 What is the arbitrage opportunity?
- 32. Hedge Funds (see Business Snapshot 1.1, page 9) Hedge funds are not subject to the same rules as mutual funds and cannot offer their securities publicly. Mutual funds must disclose investment policies, makes shares redeemable at any time, limit use of leverage take no short positions. Hedge funds are not subject to these constraints. Hedge funds use complex trading strategies are big users of derivatives for hedging, speculation and arbitrage
