Contango

From Wikipedia, the free encyclopedia

Contango is a futures market term. 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. A contango is normal for a non-perishable commodity which has a cost of carry. Such costs include warehousing fees and interest forgone on money tied up, less income from leasing out the commodity if possible (e.g. gold).

Markets for non-perishable goods may also exist in a state of contango. For example crude oil prices in 2006 have routinely been in a state of contango.

The contango should not exceed the cost of carry, because producers and consumers can compare the futures contract price against the spot price plus storage, and choose the better one. Arbitrageurs can sell one and buy the other for a risk-free profit too (see rational pricing – futures).

If there is a near-term shortage, the price comparison breaks down and contango may be reduced or perhaps even reverse altogether into a state called backwardation. In that state, near prices become higher than far prices because consumers prefer to have the product sooner rather than later (see convenience yield), and because there are few holders who can make an arbitrage profit by selling the spot and buying back the future. A market that is steeply backwardated — i.e., one where there is a very steep premium for material available for immediate delivery — often indicates a perception of shortage in the underlying commodity. By the same token, a market that is deeply in contango may indicate a perception of supply surplus in the commodity.

For perishable commodities, price differences between near and far delivery are not a contango. Different delivery dates are like different commodities in this case, since fresh eggs today are not fresh in 6 months time, or 90-day treasury bills will mature, etc.

In the past on the London Stock Exchange, contango was a fee paid by a buyer to a seller when the buyer wished to defer settlement of the trade they had agreed. The charge was based on the interest forgone by the seller not being paid.

The purpose was normally speculative. Settlement days were on a fixed schedule (such as fortnightly) and a speculative buyer did not have to take delivery and pay for stock until the following settlement day, and on that day could "carry over" their position to the next by paying the contango fee. This practice was common before 1930, but came to be used less and less, particularly after options were reintroduced in 1958.

This fee was similar in character to the present meaning of contango, i.e. future delivery costing more than immediate delivery, and the charge representing cost of carry to the holder.
