23.5 COST OF CARRY
The cost of carry is equivalent to the cost of storing a commodity. The major components of the cost of carry include:
In Exhibit 23.1, if the commodity is needed three months in the future, in theory it would make no difference to the buyers whether they paid $4.25 today in addition to $0.31525 in storage costs or paid a futures price of $4.56525 for delivery in three months' time. For these calculations, we ignore commissions and transaction costs.
