What is "contango," and where did the word come from?

Contango is when the futures price is above the expected future spot price. Because the futures price must converge on the expected future spot price, contango implies that futures prices are falling over time as new information brings them into line with the expected future spot price.

'Contango is a term used in the futures market to describe an upward sloping forward curve (as in the normal yield curve). One says that such a forward curve is "in contango" (or sometimes "contangoed").

Formally, it is the situation where, and the amount by which, the price of a commodity for future delivery is higher than the spot price, or a far future delivery price higher than a nearer future delivery.

The opposite market condition to contango is known as backwardation'
