1. The degree of change in quality of the underlying asset on a futures contract that is allowed. Every futures contract specifies the quality of the commodity underlying it that must be delivered in order for the seller to fulfill the contract. The differential allows the seller to deliver a good of a different quality, at least within certain limits. Not all futures contracts allow for differentials.

2. A change in the location of delivery that some futures contracts allow the seller to make at his/her discretion.


1. In commodities trading, the premium or discount in the futures contract price caused by delivering a commodity that does not exactly meet the standards fixed by the exchange. Allowances for these differentials are included in the contract specifications.
