SECTION SUMMARIES
Definitions
Hedging is the process of protecting oneself against future price changes by shifting
some or all of the risk to someone else, and involves using one transaction to offset the
effect of another transaction.
Hedger is the one who wants to shift risk away from him/herself.
Speculator is the one who accepts a greater risk, with a view to profit from the change in
the asset’s price.
Hedge funds represent a pooling of funds from wealthy investors and large institutional
investors that use spot and derivative market instruments to reduce investment risk (by
combining leverage and short-selling).

Margin is the amount of cash (deposit) put up by the investor as a security against the
purchase of an asset or used to ensure that a particular contract is fulfilled. The margin is
a fraction of the value of the asset.
Financial Futures and Forwards
Future contracts are agreements to accept (buy) or make delivery of (sell) an asset on a
particular future date at a price struck today. In a spot market (cash market), the asset is
delivered at the same time as the determination of price. Future contracts are made both
in financial and commodity markets.
Financial futures are an innovation of recent decades. Following the post-war
system of fixed exchange rates, many countries moved towards deregulation of financial
systems in response to the problem of exchange rate variability. This resulted in increased
volatility in the prices of all financial assets, leading to the emergence of financial
futures.
Forward Markets: Forward contracts are made in forward markets. In a forward contract,
the seller undertakes to provide the buyer with an amount of an asset at some future date
at a price agreed to in advance.
Forward and Futures Markets Compared: Forward and futures markets are alike in many ways:
both deal in durable storable products; both can be used for hedging; both require estimates of the
future from participants. They are different in that: a) the buyer in a forward contract generally
intends to take future delivery of the asset, whereas futures market participants typically intend to
make offset transactions; b) forward contract participants are directly responsible for ensuring
that the terms of agreement are fulfilled, while in a futures contract, an intermediary ensures that
the payment and delivery are made; and c) forward contracts are concluded over the phone, while
futures markets operate in an auction setting (see Table 15.1 in the text).
The Forward Market in Operation: A Canadian importer expects to receive US$2,000,000 worth
of widgets in three months. At the current exchange rate (US$1 = C$1.50), the Canadian dollar
cost would be C$3,000,000. The importer believes that the exchange rate will change to US$1 =
C$1.60 (i.e., the Canadian dollar will depreciate), and that the cost of imports in Canadian dollars
will rise, in three months. If this were to happen the cost would be C$3,200,000. To avoid this
foreign exchange risk, the importer can arrange with a bank to deliver US$2,000,000 in three
months at today’s prevailing forward exchange rate, say US$1 = C$1.55. With this forward
contract the cost of imports is fixed at
C$3,100,000, which is less than the otherwise anticipated cost of C$3,200,000. This is a simple
example which ignores several considerations.
The Workings of Futures Markets: In futures markets, an individual who expects that
some asset prices will rise (fall) is said to take a long position (short position). The long
position is the purchase of an asset that is to be held until it matures or must be sold. The
short position is the sale and delivery of an asset in the future, with the intent to buy it at
a lower price. Hedging requires one person to take a long position and another to take a
short position. It may involve taking one position in the spot market and an opposite
position in futures market.
The difference between the futures price [F(t)] and the spot price [S(t)] is known
as the basis:

F(t) - S(t) = basis
Futures contracts are mark-to-market, which means that gains and losses are settled at
the close of trading each day, not at the end of the contract. The reporting of financial
futures differs from that of spot markets. The prices listed are points of 100 percent, not
percentages of face value. Brisk trade in futures means that their market price changes
almost constantly. There are limits on how much the price of an instrument can vary
during any one day. Stock index futures are sold in multiples of the prevailing index.
A Long Hedge: A long hedge involves an attempt to reduce the risk of lower future
interest rates. For example, suppose that interest rates are high now and that an investor
expects them to fall. The investor also expects to receive $100,000 in three months. If the
interest rates do fall, the yield on the asset the investor purchases will be less than the
yield the same asset would produce today. This implies a loss of potential interest
income. To reduce this risk (or loss), the investor can lock into the current high interest
rates by purchasing a futures contract today and selling it (at a relatively higher price)
three months from today.
A Short Hedge: A short hedge involves an attempt to reduce the risk of a future rise in
interest rates. For example, suppose that an investor owns a $100,000, 9% Government of
Canada bond due today, and that the bond sells at 87.35 in the spot market. A futures
contract is sold at a cash price of 95. The investor expects a fall in bond prices to 86.8 in
three months. The investor can reduce the potential loss by selling the equivalent of a
$100,000 bond in futures at a cash price of 95, and buying a futures contract at a lower
cash price in three months.
The Difficulty of Perfect Hedges: The sequence of future market transactions that would
produce a gain exactly equal to the loss is called a perfect hedge. A perfect hedge is
unlikely for several reasons: 1) it is not always possible to buy and sell the same asset in
the futures market; 2) spot and futures prices do not necessarily move in concert; and 3)
futures prices in both the spot and futures markets are uncertain. Therefore, hedging
cannot eliminate risk entirely.
Future Prices and Spot Prices: The futures price [F(t)] is the spot price [S(t)] plus the
cost of carry, which is the opportunity cost of carrying the contract until delivery.
F(t) = S(t) + [(RS- RL) (-t)/360)S(t)]
where RS is the yield on a short-term instrument, RL is the yield on a long-term
instrument,  is the date of the delivery, t is the today’s date. Note that as the delivery
date approaches, the cost of carry approaches zero and F(t) = S(t).
Financial Options
An option is the right (but not the obligation) to buy or sell a given amount of a
particular security at a particular price in the cash or futures market before a specified
expiration date.
The set price of options is called the exercise or strike price. The right to buy a
financial asset is a call option. The call price includes the interest and hence is greater
Page 3 of 8

than the face value. A put option is the right to sell a financial asset. A call option whose
strike price is below (above) the market price is said to be "in the money" ("out of the
money"). The buyer of a call option (put option) is protected against unexpected price
increases (decreases), while the buyer of a put option is protected against unanticipated
decreases in price.
The Mechanics of an Auction: Two Illustrations: Suppose a Canadian exporter expects
future exports earnings in US dollars, and wants to protect the Canadian dollar value of
those export earnings from falling due to future exchange rate changes. The exporter can
purchase a put option at a certain strike price (say, C$1.45 per US$1), and thereby protect
against the exchange rate falling below the strike price. A call option can be used to
protect against the exchange rate rising above the strike price.
Figure 15.1 shows how a put option places a minimum value on the US dollar
and how a call option places a maximum value on the US dollar. Figure 15.2 shows how
options narrow the distribution of asset returns and reduce interest rate risk.
The Value of Options: The value of a call at expiration (Call) is given by:
Call = MAX {0, S-E}
where S is spot price, E is exercise price, and MAX means maximum. The value of a put
option (Put) is given by:
Put = MAX{0, E-S}
where S is spot price, E is exercise price, and MAX means maximum.
According to the Black-Scholes options pricing model, three other factors (the anticipated
volatility of an underlying asset’s price, the interest on a riskless asset, and the time until
the exercise date) also help to determine the value of options.
A Numerical Example: This example shows how a British company which wants to
purchase C$2,000,000 in 90 days, and anticipates an appreciation of the Canadian dollar,
protects itself from a possible increase in the cost of purchasing Canadian dollars by
purchasing a call option.
Hedging with Options: The crucial point that drives the choice of a call or a put, is the
expectations of investors. If shares are expected to fall (rise) in the short-term the investor
will want to write a call (put). The expectations will also drive the strategy of the investor
as the expiration date of the call or put approaches. The gains or losses from the choice of
options will depend on the fee/premium and the differential between the market and
exercise prices.
Swaps: Interest rate swaps and foreign exchange swaps are derivatives designed to
protect lenders and borrowers from unfavourable changes in interest rates and exchange
rates.
A swap is an agreement to exchange, for a pre-agreed period into the future, a series of
interest payments or foreign exchange at fixed rates for a series of available interest
payments or for foreign currency at a variable exchange rate. Note that, in the case of
swaps, the ownership of the underlying asset does not change.

The Importance of Hedging in the Financial System
The dollar value of futures and options is difficult to measure since they appear as offbalance sheet items in the financial statements of chartered banks. Banks, large
corporations, and small businesses all use derivatives to hedge against unfavourable
changes in interest rates and exchange rates. Globally, hedging instruments have spread
rapidly. Among the derivative products, swaps pose relatively less "systematic risk" in
the financial system than do other derivative products.

Answers to problems:
1.
(a) (1350-1200)/1200 = 0.125 (or 12.5%).
(b) The yield in Canadian dollars can be calculated as follows:
[(1350 x 1.30) - (1200 x 1.20)]/(1200 x 1.20) = (1755-1440)/1440
= 0.21875 (or 21.875%)
(c) The yield in Canadian dollars can be calculated as follows:
[(1350 x 1.00) - (1200 x 1.20)]/(1200 x 1.20) = (1350-1440)/1440
= -0.0625 (or -6.25%)
2. Cost of exercising the option = C$1.30 x 500,000 + C$0.02 x 500,000
= C$650,000.00 + C$10,000.00
= C$660,000.00
Cost at the spot rate 90 days from today = C$1.35 x 500,000
= C$575,000.00
Therefore, exercising the option is relatively less costly.
3. If unhedged, the cost of the unhedged purchase would be $10 x 5000 = $50,000.
If hedged, the purchase cost would be $7.50 x 5000 = $37,500; sales revenue would be
$10.90 x 5000 = $54,500, and profit generated would be $(54,000-37,000) = $17,000.
The net cost, therefore, would be $(50,000-17,000) = $33,000.
4.a) A hedger is one who wants to shift risk away from him/herself. A speculator is
one who accepts a greater risk, with a view to profit from the change in an asset’s price.

b) A futures contract is a contract to buy or sell an asset at a specified future date. A
forward contract is a contract according to which a seller agrees to sell an amount of an
asset to a buyer at a future date at a price agreed upon in advance.
c) A call option is the right, but not obligation, to buy an asset at a particular price during
a stipulated period. A put option is the right, but not obligation, to sell an asset at a
particular price during a stipulated period.
