The value of a forward contract at initiation is zero. Over time, the value depends on the relationship between the forward price and the expected future spot price. Futures prices also converge to the spot price at expiration. Like forwards, futures have value of zero at initiation but are marked to market daily. Factors like storage costs, convenience yields, and interest rates can cause the futures price to be in contango or backwardation relative to the expected future spot price.

10. Convergence of Futures Price
to Spot Price at Expiration
long - The party in the futures contract that agrees to buy the
asset in the future is called the.
short - The party agreeing to sell the asset is called the.
futures price - the price today for the delivery of an asset in the
future.
spot price - the price for immediate delivery.
The spot price at expiration must equal to the futures price.
If the prices are not the same, there will be an arbitrage
opportunity.

of a Futures Contract

change since the last marked to market.
Value of futures contract at expiration=0

15. Normal Backwardation
backwardation - when the futures price is less than the spot
price in the market. In backwardation the benefits are more
than the costs plus interest.
normal backwardation theory - the markets are lead by hedgers
who hold short positions. This theory states that the futures
price is less than the expected future spot price.

contango - when the futures price is greater than the spot price
in the market. In contango, the benefits are less than the cost
plus interest.
