What is a Futures Contract?

A futures contract is a contractual agreement to buy or sell a specific commodity or financial instrument at a pre-determined price in the future. This usually occurs on the trading floor of a futures exchange. Some futures contracts require physical delivery of the asset, while others are settled with money.

Buyers and suppliers opt for a futures contract because they seek price stability.

The futures exchange acts as the mediator between the two parties involved. In contrast to an option, both parties of a futures contract must fulfill the contractual agreement on the delivery date.

The buyer of the contract known as the ‘long’, while the seller is the ‘short’.

Futures Contract If milk goes below $3 dollars the investor pays the difference to the farmer. If it goes above $3, the investor keeps the difference. The contract with the ice-cream seller works the opposite way.

According to nasdaq.com, a futures contract is:

“A legally binding agreement to buy or sell a commodity or financial instrument in a designated future month at a price agreed upon at the initiation of the contract by the buyer and seller.”


A futures exchange institution not only acts as an intermediary but also mitigates the risk of a default occurring. A margin is required by both parties (an initial amount of cash) – typically 5%-15% of the contract’s value.

As a futures price changes on a daily basis, the price that was agreed upon at the time the contract was made and the change in a futures price (on a daily basis) is settled on a regular basis (variation margin).

The exchange will take money out of one party’s margin account and allocate it into the other, depending on the daily profit or loss.

When a margin account falls below a specific value, then a margin call is made and the owner of the account must add money back into it (a process known as marking to market).

On the delivery date, the amount exchanged is not equal to the price agreed upon when the contract was created, it also accounts for the spot value – any gains or losses that have been settled by marking to market.

Definition of a futures contract, according to Björk:

There is a quoted price F(t,T) –  the futures price at time t for delivery of J at time T.
During any time interval [t,s] , the holder receives the amount F(s,T) – F(t,T).
At T, the holder pays F(T,T) and is receives J.
