How It Works
On November 29, 2010, the spot price of gold was $1,367.40 per ounce on the New York Commodities Exchange (COMEX). That was the price at which one ounce of gold could be purchased at that particular moment in time. The spot price for a bushel of wheat was about $648 on the same day.
On November 29, 2010, the futures price for an ounce of gold to be delivered in December 2011 was $1,373.20. The futures price for December 2011 delivery of a bushel of wheat was about $764.
Large differences between the spot price and the futures price can exist because the market is always trying to look ahead to predict what prices will be. Futures prices can be either higher or lower than spot prices, depending on the outlook for supply and demand of the asset in the future.
