Derivatives Markets

Exchange Traded




standard products
trading floor or computer trading
virtually no credit risk
Over-the-Counter



non-standard products
telephone market
some credit risk
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 an investment
without incurring the costs of selling one

Forward Contracts

A forward contract is an agreement to buy or sell an asset
at a certain time in the future for a certain price (the
delivery price)




It can be contrasted with a spot contract which is an agreement to
buy or sell immediately
The contract is an over-the-counter (OTC) agreement
between 2 companies
The delivery price is usually chosen so that the initial
value of the contract is zero
No money changes hands when contract is first
negotiated and it is settled at maturity
The 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

agreement to buy £1 million in three months at an
exchange rate of 1.6196
This obligates the trader to pay $1,619,600 for £1
million on November 20, 2006

Futures

Futures - similar to forward but feature formalized and
standardized characteristics



Agreement to buy or sell an asset for a certain price at a certain time
Whereas a forward contract is traded OTC a futures contract is
traded on an exchange
Key difference in futures


Exchange traded
Specifications need to be defined:




What can be delivered,
Where it can be delivered,
When it can be delivered
Settled daily
Options


A call option is an
option to buy a
certain asset by a
certain date for a
certain price (the
strike price)
Exotic options

A put is an option to
sell a certain asset
by a certain date for
a certain price (the
strike price)

Examples

Insurance as options



Put options is an insurance for an asset one already
owns
Call option is insurance for an asset one plans to own
in the future
Equity linked CDs


Example: a simple 5 ½ year CD with a return linked to
the S&P 500 might have the following structure: at
maturity the CD is guaranteed to reply the invested
amount, plus 65% of the simple appreciation in the
S&P 500 over that time.
What is the payoff?

Swaps
A swap is an agreement to exchange cash
flows at specified future times according to
certain specified rules
 Basic forms of swaps


Interest rate swaps;
currency swaps

An Example of a “Plain Vanilla” Interest
Rate Swap

An agreement by Microsoft to receive 6month LIBOR & pay a fixed rate of 5% per


Converting a liability
from
 fixed rate to
floating rate
 floating rate to
fixed rate

Converting an
investment from
 fixed rate to
floating rate
 floating rate to
fixed rate

Currency Swap
Example
An agreement to pay 11% on a sterling
principal of £10,000,000 & receive 8% on a
US$ principal of $15,000,000 every year for 5
years

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
26
Credit Risk



A swap is worth zero to a company initially
At a future time its value is liable to be either
positive or negative
The company has credit risk exposure only
when its value is positive

The risk is asymmetric!
27
Swaptions

What is a swaption?



Swap + Option = swaption
It is an option written on a swap rate
How does it work?
28
Credit Derivatives

Credit Default Swap



Company A buys default protection from B to
protect against default on a reference bond issued
by the reference entity, C.
A makes periodic payments to B
In the event of a default by C


A has the right to sell the reference bond to B for its face
value, or
B pays A the difference between the market value and
the face value
