Figure 22.4 illustrates the nature of the hedge in Example 22.5. The upward-sloping
line is the revenue from the sale of oil. The downward-sloping line is the profit on the
futures contract. The horizontal line is the sum of sales revenue plus futures profits. This
line is flat, as the hedged position is independent of oil prices.
To generalize Example 22.5, note that oil will sell for P
T
per barrel at the maturity of
the contract. The profit per barrel on the futures will be F

T
. Therefore, total revenue
is P

, which is independent of the eventual oil price.
The oil distributor in Example 22.5 engaged in a
short hedge, taking a short futures
position to offset risk in the sales price of a particular asset. A long hedge is the analogous
hedge for someone who wishes to eliminate the risk of an uncertain purchase price. For
example, a power supplier planning to purchase oil may be afraid that prices might rise by
the time of the purchase. As the following Concept Check illustrates, the supplier might
buy oil futures to lock in the net purchase price at the time of the transaction.
The revenue from the oil sale plus the proceeds from the contracts equals the current
futures price, $91.86 per barrel. The variation in the price of the oil is precisely offset by
the profits or losses on the futures position. For example, if oil falls to $89.86 a barrel,
the short futures position generates $200,000 profit, just enough to bring total revenues
to $9,186,000. The total is the same as if one were to arrange today to sell the oil in
February at the futures price.
Suppose as in Example 22.5 that oil will be selling in February for $89.86, $91.86, or $93.86 per barrel. Con-
sider a firm that plans to buy 100,000 barrels of oil in February. Show that if the firm buys 100 oil contracts
today, its net expenditures in February will be hedged and equal to $9,186,000.
