Commodity Futures Pricing
Discounted Cash Flow Analysis for Commodity Futures
Given the current expectation of the spot price of the commodity at some future date and
a measure of the risk characteristics of that price, we can measure the present value of
a claim to receive the commodity at that future date. We simply calculate the appropri-
ate risk premium from a model such as the CAPM or APT and discount the expected
spot price at the appropriate risk-adjusted interest rate, as illustrated in the following
example.
The general rule, then, to determine the appropriate futures price is to equate the present
value of the future payment of F
0
and the present value of the commodity to be received.
This implies
