What is Long The Basis

Long the basis refers to a situation when a trader who owns or has purchased, a commodity, such as oil, gold or lumber, hedges their investment by selling futures contracts on the commodity. This hedging provides a guaranteed price at which they may sell their commodities if the market price moves against their underlying position. For background, see the entry on basis trading.


Long the basis, by definition, means that the investor must be bullish on a particular commodity, and usually is looking to hedge their bullish position. For instance, a gold-mining company maintains a significant position in the precious metal. However, the price of gold is susceptible to market pressures and is likely to fluctuate at times. To hedge against adverse changes the company may choose to buffer its bullish stance through the sale of futures contracts and thus lock in a guaranteed range of value.

In contrast, a trader who is bearish on a commodity may enter into a short the basis trade. Shorting the basis implies that the investor will be taking a short position in the commodity and a long position in the futures contract. This strategy is used to hedge a position by locking in a future spot or cash price and thereby removing the uncertainty of rising prices.

Both the long the basis and the short the basis trades are basis trading strategies. Basis trading relates to a trading strategy in which a trader believes that two similar securities are mispriced relative to each other, and the trader will take opposing long and short positions in the two securities to profit from the convergence of their values.

Example of Long The Basis

It is August, and the Jones family, farmers in the Midwest, have agreed to sell their soybean crop to a wholesaling group Soy Tofu. The contracted price is $400 a ton, which is the current cash price. The wholesalers think they have gotten a good deal, believing that soybean prices will rise in coming months. However, they also are a bit concerned about what it would mean for their profit, at resale, if bean prices were to fall.

As a result, Soy Tofu decides to sell soybean futures at $425 per ton. The wholesalers are now long the basis, meaning they are long soybeans and short soybean futures. If the price falls, being long the basis will guarantee a favorable price at which they can resell. Their cost basis, in this case, is negative $25, or cash of $400, minus futures of $425.

The wholesalers are making a trade-off, however. They are exchanging price risk for basis risk, that is, the risk that the price of soybeans and soybean futures will not move in lockstep. The wholesalers will profit if the differential between soybean and soybean futures prices narrows. However, a widening of this differential will result in a loss.

Rather than for hedging purposes, the wholesalers may also choose to go long the basis by speculating about the price differential between soybeans and soybean futures. Perhaps they believe local prices for soybeans will rise. If the price reaches $450 while the futures price advances only to $430, their net proceeds due to the narrowing of the basis will be $25 on the soybeans, negative $5 on the soybean futures for a total of $20. Their bullish bet will have paid off.

However, if the price of soybeans stays at $400 while the futures price rises to $435, the basis will be negative $35. The widening of the basis from the previous negative $25 will result in a $10 per-ton loss.

Note that it is also possible for the Jones family to go long on the basis, as well. To do so, they would hold their soybeans in storage and sell soybean futures. The family may choose to do this if they think local soybean prices will rise.
