A forward contract—or forward—is
an OTC
derivative. In its
simplest form, it is a trade that is agreed to at one point in time but
will take place at some later time. For example,
two parties might agree today to exchange 500,000 barrels of crude oil for
USD
42.08 a barrel three months from today.
A forward contract is specified with four variables:
the
underlier,
the
notional amount
n,
the
delivery price k, and
the
settlement
date on which the underlier and payment will be exchanged.
In our example, oil is the underlier. The notional amount
is 500,000 barrels. The delivery price is USD 42 per barrel. The
settlement date is the actual date three months from now when the oil will
be delivered in exchange for a total payment of USD 21.04MM.
The party who receives the underlier is said to be
long
the forward. The other party is short.
At settlement, the forward has a
market value given by
where s is the
spot price of the underlier at
settlement. This formula derives from the fact that, at settlement, the
long party is paying a delivery price k for an underlier then
trading at price s. The difference between those two prices,
multiplied by the notional amount, is the market value of the forward.
Formula [1] tells us that forwards have linear
payoffs. This is depicted in
Exhibit 1. Compare with the options payoffs depicted in the article
options spreads.

Forwards have linear payoffs. Graphs
depict the profit or loss from holding a forward as a function of
underlier value at settlement. |
A forward may be
cash settled, in which case the underlier
and payment never exchange hands. Instead, the contract settles with a
single payment for the market value of the forward at settlement, as given
by [1]. If the market value is positive, the short party pays the long
party. If it is negative, the long party pays the short party.
Suppose the forward in our oil example were cash-settled.
On the settlement date three months from today, no oil would change hands, and there would be no payment of USD
21.04MM. If the spot price at settlement were, say, USD 47.36, then the forward
would settle with a single payment of
|
500,000(47.36 – 42.08) = USD 2.64MM |
[2] |
made by the short party to the long party.
Forward are generally quoted as delivery prices, which are
called forward prices. Forward prices
fluctuate with market conditions. When a forward is entered into, the
contract's delivery price is set equal to the quoted forward price. That
delivery price then remains fixed until the forward settles. For example,
a dealer might quote a three-month oil forward at 41.25/41.29. Those are
the bid and offer forward prices. If a counterparty accepts the offer
price for 500,000 barrels, then the delivery price on that contract will
be USD 41.29.
Issues such as the
time value of money, short-term supply
and demand, market expectations of future spot prices and cash-and-carry
arbitrage tend to make forward prices diverge from spot prices, but
relevant factors vary from one market to the next. A graph of forward
prices for different maturities is called a forward curve.
Exhibit 2 shows the forward curve for West Texas intermediate crude oil on
September 15, 2005.

Forwards are a convenient vehicle for
hedging or
speculation. For example, an airline can conveniently hedge its fuel costs
by purchasing jet fuel several months forward. The hedge eliminates price
exposure, and it doesn't require an initial outlay of funds to purchase
the fuel. The airline is hedged without having to take delivery of or
store the jet fuel until it is needed. It doesn't even have to enter into
the forward with the ultimate supplier of the jet fuel. If the forward is
cash settled, the hedge can be put on with any counterparty.
Prior to settlement, a forward has a market value given by
where f is the current forward price and d
is the discount
factor. Returning to our oil example, suppose it is now a month until
the contract settles, one-month Libor
is 2.18, and the one-month forward price for oil is USD 45.16. Then
 |
[4] |
and the forward has market value
|
(.9981) 500,000 (45.16 – 42.08) = USD 1.54MM |

There are active forward markets on a variety of
commodity, energy and financial underliers. These include forward markets
for coffee, cocoa, cotton, natural gas, oil and electricity. The largest
forward market is the interbank foreign exchange forward market.
Forward rate agreements
(FRAs) are cash-settled forwards on short-term loans.
Forwards entail
market risk,
presettlement risk and
settlement risk. With cash-settled forwards, there can also be a risk
of manipulation of the underlier price index used for calculating the
settlement value. This has been a problem in energy markets when the
paper market dwarfed
the physical market.
In such a situation, a small physical transaction performed at an
off-market price could impact the settlement value of a far greater volume
of paper transactions.
Forwards are similar to
futures. The primarily difference is that forwards trade OTC while
futures are exchange traded.
Daily margining of futures eliminates
presettlement and settlement risk for those contracts.
