Title: 1Introduction to Forward Derivative Contracts
11Introduction to Forward Derivative Contracts
22Forward Derivative Contract Defined
- Defn A forward contract is a formal agreement
between two parties to exchange specified assets
over specified future time periods (see example). - That it is a contract suggests that it is a
legally binding agreement. Time may reveal that
you would have been better off, ex-post, if you
had not signed the contract. And so a means of
enforcement may be necessary as a precautionary
measure.
33Spot Contracts (Simultaneity)
- An alternative is a spot agreement. Spot
agreements are sometimes legally binding, in
which case they are spot contracts. - Defn A spot agreement/contract is an
agreement/contract between two parties to
exchange an asset immediately (or within a very
short period of time from now) at a certain price
(usually the prevailing spot price). - Examples include trades of used cars, pens of
cattle, and items in WalMart. The law may turn a
spot agreement into a formal contract by, for
example, obliging parties to the trade to nullify
the agreement if one party changes its mind
within a specified period of time subsequent to
the spot trade. Financing contracts may also be
tied to a spot trade.
44Forward vs. Spot Contracts
- Forward agreements are usually more formal in
nature than spot agreements. This is because
they are generally more complicated and risky
than spot agreements. Specifically, - there should be agreement on what to deliver and
when. If you are obliged to deliver 100 tons of
corn in one month then you will likely deliver
the lowest quality corn available on the spot
market. Quality issues arise more often in
commodity markets than in security markets, but
related issues are common in bond markets because
bond derivatives may cover several types of
bonds. - Depending upon intervening price movements,
forward agreements may acquire positive/negative
value. As a precaution, it may be best to have a
legal means of enforcement.
55Examples of Forward Contracts
- Packerland Packing Co. Contract.
- An agreement to sell 4,000 oz of gold _at_290/oz on
1/29/2001. - An agreement to buy 2,000,000 ECU _at_ 1.1/ on
9/1/2001. - An agreement to earn 5 interest compounded
quarterly on 1,000,000 for 1 year starting
September 1st 2000. - An agreement to sell 2,000,000 Bu wheat _at_
3.35/Bu on February 2nd 2000.
66OTC Nature of Forward Contracts
- The contract is generally over-the -counter
(OTC). i.e., the deal is agreed upon in an
environment whereby the parties are not
constrained to pre-determined contract
specifications. The parties can write a contract
to suit their particular needs provided it does
not violate regulatory constraints. - Normally when a forward contract is first written
the forward price is chosen so that the contract
initial value is 0. That is, there is no need
to buy ones way into a contract when it is first
written. It is for convenience that the initial
value is generally 0. Why not 10 (or - 10)?
Then the forward price would likely differ from
what one might expect it to be. Then one may
think of the forward contract as an agreement to
sell forward at a reasonable price plus a loan
agreement.
77Issues when Writing Forward Contracts
- The specifications of a forward contract can be
quite complicated because the purchaser wants to
be clear about what is delivered. Issues that
may arise include the ability to measure quality,
the cost of measuring quality, who measures it,
transportation, and delivery points. - While flexible in term of their content, once
entered into forward contracts tend to be
inflexible. Both parties must agree to any
change. This is a very important issue. There
are many reasons why a party might wish to exit a
forward contract during its duration. Market
conditions may change.
88Issues when Writing Forward Contracts, Contd
- A firm may learn more about future
production/financing activities. It may be
difficult/costly to extricate oneself from such
an agreement (time costs, payment of
compensation, legal costs). - Among all forward contracts, foreign exchange
forwards are generally easiest to get out of
because they are so liquid and because
specifications often do not differ much across
contracts. In fact, it is often possible to
exit the contract by entering a second contract
that reverses your previous position, e.g., sell
forward to offset a situation where you had
bought forward.
99Forward Price
- Defn The time to maturity of a contract is the
time until delivery. - For example, if it is now time t and delivery
(maturity) is at time T, then the time to
maturity is T - t. - Defn The forward price FT,t at time t for a
forward contract with maturity at time T is the
delivery price at time T which is guaranteed in
the contract.

1010The Long and the Short of a Contract
- There are generally two parties to a forward
contract. The party that agrees to buy forward
(i.e., take delivery) is said to assume the long
position, and the party that agrees to sell
forward (i.e., deliver) is said to assume the
short position. As a mnemonic, s is for sell and
for short. - Example On January 12th 2000 a firm agrees to
buy 10,000,000 Euros at 1.05/ in 90 days.
Here, the firm is taking a long position in the
forwards market. At maturity, in 90 days, let
the exchange rate on the spot market be 1.03/.
The firm pays 10.5 mill., and takes delivery of
1 mill. Euros. But these are worth 10.3 mill.
in the spot market, and so the long position
incurs a loss of 0.2 mill.
1111The Long and the Short of a Contract, Contd
- The firm made a loss on being long because the
spot price fell after the agreement was entered
into. Ex-post, the firm might like to reneged on
the agreement, but it couldnt. - Had the spot price moved up, the long firm would
profit. E.g., if the spot price at maturity were
1.07/ then the long would book a gain of 0.2
mill. - Note the symmetry
- for every long position that is assumed, some
party always assumes a short position - for every short position that is assumed, some
party always assumes a long position - apart from transactions costs, accounting gains
and losses are zero sum. As in gambling, what
someone gains someone loses.
1212Comments on Purposes of Forwards
- If all that occurs is a wealth transfer, then why
the big deal? Shouldnt society view forwards as
just gambling? - Briefly, there are two responses.
- Forwards allow firms to manage risk, or trade
risk so that those in a better position to cope
with the possible consequences of risk are those
that actually assume it. - Risk markets in general reveal (free) information
to others. To that extent, risk markets generate
a positive externality. This information allows
firms to plan better and so be more efficient in
using scarce resources. - Defn A positive externality occurs to party B if
actions taken by party A in pursuit of private
interests improve the welfare of B even though B
does not reward A. (von Hayek intangibles)

1414Position Diagram, Contd
- Note that profit in the long position is
increasing in the underlying variable. You
commit to buy now at a fixed price. If price
rises before maturity, then you can take delivery
at maturity and sell at a profit. Alternatively,
you can consume the item delivered and you paid a
price lower than the prevailing price for the
items you consumed. - Conversely, if price falls before maturity, then
you must take delivery at maturity and you have
bought at over the prevailing spot price.

- Now suppose a firm holding a long position
decides to double the size of that long position.
The position diagram continues to intersect the
horizontal axis at the same point, but the slope
is twice as large. If the size of the long
position is halved, then the slope is halved.

1818Flexibility and Forwards
- Now lets review the nature of forward contracts
- They are OTC, and can be tailored to fit
(ex-ante) the needs of the parties involved. - But there are so many requirements about product
type that have to be met, and - parties are bound to dealing with the other party
(i.e., a 1-to-1 relationship between shorts
longs), and - it is necessary to deliver unless the short gets
the long to agree with some other form of
settlement. - Is there a way of locking into a future price
without encountering these inconveniences? Yes
futures contracts.
