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

1. Gold: An Arbitrage Opportunity?
Suppose that:The spot price of gold is US$900The 1-year forward price of gold is US$1,020The 1-year US$ interest rate is 5% per
annum
Is there an arbitrage opportunity?

2. Gold: Another Arbitrage Opportunity?
Suppose that:- The spot price of gold is US$900- The 1-year forward price of gold is US$900- The 1-year US$ interest rate is 5% per
annum
Is there an arbitrage opportunity?
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 12
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 = 900, T = 1, and r =0.05 so that
F = 900(1+0.05) = 945

Hedging Strategies Using Futures
Chapter 3
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 19
Long & Short Hedges
A long futures hedge is appropriate when you know you will purchase an asset in the future and want to lock in the price
A short futures hedge is appropriate when you know you will sell an asset in the future and want to lock in the price
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 20
Arguments in Favor of Hedging
Companies should focus on the main business they are in and take steps to minimize risks arising from interest rates, exchange rates, and other market variables
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 21
Arguments against Hedging
Shareholders are usually well diversified and can make their own hedging decisions
It may increase risk to hedge when competitors do not
Explaining a situation where there is a loss on the hedge and a gain on the underlying can be difficult
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 22

Basis Risk
Basis is the difference between the spot and futures price
Basis risk arises because of the uncertainty about the basis when the hedge is closed out
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 24
Long Hedge
We defineF1 : Initial Futures Price
F2 : Final Futures Price
S2 : Final Asset Price
If you hedge the future purchase of an asset by entering into a long futures contract then
Cost of Asset=S2 – (F2 – F1) = F1 + Basis
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 25
Short Hedge
Again we defineF1 : Initial Futures Price
F2 : Final Futures Price
S2 : Final Asset Price
If you hedge the future sale of an asset by entering into a short futures contract then
Price Realized=S2+ (F1 – F2) = F1 + Basis
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 26
Choice of Contract
Choose a delivery month that is as close as possible to, but later than, the end of the life of the hedge
When there is no futures contract on the asset being hedged, choose the contract whose futures price is most highly correlated with the asset price. This is known as cross hedging.

Swaps
Chapter 7
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 28
Nature of Swaps
A swap is an agreement to exchange cash flows at specified future times according to certain specified rules
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 29
An Example of a “Plain Vanilla” Interest Rate Swap
An agreement by Microsoft to receive 6-month LIBOR & pay a fixed rate of 5% per annum every 6 months for 3 years on a notional principal of $100 million
Next slide illustrates cash flows that could occur

Valuation of an Interest Rate Swap That Is Not New
Interest rate swaps can be valued as the difference between the value of a fixed-rate bond and the value of a floating-rate bond
Alternatively, they can be valued as a portfolio of forward rate agreements (FRAs)
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 37
Valuation in Terms of Bonds
The fixed rate bond is valued in the usual way
The floating rate bond is valued by noting that it is worth par immediately after the next payment date
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 38
Valuation in Terms of FRAsEach exchange of payments in an interest rate swap is an FRA
The FRAs can be valued on the assumption that today’s forward rates are realized
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 39
An Example of a Currency SwapAn agreement to pay 5% on a sterling principal of £10,000,000 & receive 6% on a US$ principal of $18,000,000 every year for 5 years
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 40
Exchange of Principal
In an interest rate swap the principal is not exchanged
In a currency swap the principal is usually exchanged at the beginning and the end of the swap’s life

Typical Uses of a Currency Swap
Conversion from a liability in one currency to a liability in another currency
Conversion from an investment in one currency to an investment in another currency
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 43
Valuation of Currency Swaps
Like interest rate swaps, currency swaps can be valued either as the difference between 2 bonds or as a portfolio of forward contracts
Options, Futures, and Other Derivatives, 7th International Edition, Copyright © John C. Hull 2008 44
Swaps & Forwards
A swap can be regarded as a convenient way of packaging forward contracts
Although the swap contract is usually worth zero at the outset, each of the underlying forward contracts are not worth zero
