INTRODUCTION

Corn producers are constantly faced with production and market risks. Various

strategies can be used to minimize these risks. Market or price risk can be effectively

managed with a marketing plan that includes the use of futures markets through hedging or

using options. The use of futures markets allows producers to minimize downside cash price

risk by establishing a price floor or a price range. The determination of the final price

producers receive using such marketing strategies is affected by deviations in the expected

difference between local cash prices and futures contract prices at marketing. This difference

is called the basis. This publication defines basis and discusses terms frequently associated

with basis analysis. Several of the factors which affect basis are also discussed. A brief

section is included on understanding the importance of basis in hedging. The remainder of

the publication contains corn basis tables and graphs calculated for Campbellton, a major sales

point for commodities grown in North Florida. These graphs and tables provide information

about historical corn basis.



BASIS TERMINOLOGY

Basis is calculated by subtracting the price of a futures contract from the commodity

cash price at a particular point in time. For example, if September corn contracts are trading

for $2.90, and the local cash market for corn in August is $2.70 per bushel, the basis is 20

cents under the September futures price ($2.70 $2.90 = -$0.20). Basis is always

determined for a particular market location since cash prices differ from market to market.

Basis may be calculated as a current basis or a harvest basis. Current basis is found using

the nearby or current futures contract month. Harvest basis is calculated using the contract

which expires near the harvest month. For corn, the harvest month contract is typically the

point for commodities grown in North Florida. These graphs and tables provide information

about historical corn basis.



BASIS TERMINOLOGY

Basis is calculated by subtracting the price of a futures contract from the commodity

cash price at a particular point in time. For example, if September corn contracts are trading

for $2.90, and the local cash market for corn in August is $2.70 per bushel, the basis is 20

cents under the September futures price ($2.70 $2.90 = -$0.20). Basis is always

determined for a particular market location since cash prices differ from market to market.

Basis may be calculated as a current basis or a harvest basis. Current basis is found using

the nearby or current futures contract month. Harvest basis is calculated using the contract

which expires near the harvest month. For corn, the harvest month contract is typically the










September contract. The current basis and the harvest basis are the same during the harvest

season.

There are several characteristics to consider when analyzing basis. A basis is said to

be under if the cash price is lower than the futures price and over if the cash price is higher

than the futures price. If the basis becomes more positive over time, the basis is

strengthening. Conversely, a basis that becomes more negative over time is weakening.

Basis also narrows and widens. A basis narrows as cash and futures prices converge. A

narrowing basis typically occurs near harvest when cash prices are peaking and futures prices

reflect only transportation costs. Basis usually widens after harvest, as cash prices fall and

futures prices rise to reflect storage and interest costs.



FACTORS AFFECTING BASIS

The following economic factors typically affect basis.

Transportation Costs. The basis reflects costs of moving a commodity from a

production point to a futures delivery point. For example, if the cost to move corn from

Florida to Chicago, the delivery point for futures contracts, is 40 cents per bushel, then the

corn price in Chicago should be at least 40 cents higher than prices in Florida. If not, corn will

not be transported to the Chicago market. The shorter the distance between markets, the

narrower the basis will be.

Storage Costs. Monthly storage costs accumulate during the crop year. The further

away the delivery month, the higher the carrying charges will be to reflect storage costs until

that time. As a futures delivery month approaches, carrying charges will decline until the

basis reflects mainly transportation costs.









Interest Costs. Interest costs are incurred with stored commodities since either

borrowed or equity capital is committed to the investment. The longer commodities are

stored, the longer cash returns are delayed, causing the interest portion of the basis to be

greater the further away from the futures contract maturity.

Local Market Conditions. Supply and demand determinants in local cash markets may

differ from those in the national market. A commodity may command a premium over the

futures price or be discounted relative to the futures price because of local commodity

surpluses or deficits. Local supply and demand for a commodity should be considered when

localizing, or adjusting futures prices for basis. Seasonal local supply and demand conditions

are particularly important to consider.

Additional factors affecting the basis may include: variations between the cash

commodity quality and the contract grade specifications; supply, demand, and prices for

substitute commodities; and future price expectations. Storage costs and transportation costs

are generally considered the principle factors affecting basis.



USING BASIS

An understanding of basis is necessary to determine the expected local effective price

when using futures markets to manage market risk. The basis is used to translate a futures

price to the approximate selling price established by a market strategy. The following example

illustrates how the basis is used to determine the expected final market price established by

hedging in the futures market.










Example

Cash Market

March 31

expected price:
$3.00/bu
($3.20 $0.20)


Futures Market

sell Sep contract

Sep futures price:
$3.20/bu


Basis



expected basis:
$0.20 under


sell corn:
$2.65/bu


Hedging Summary 1
expected market price
change in basis ($0.20 $0.25)
net return


Hedging Summary 2
cash price received
gain/loss in futures ($3.20 $2.90)
net return


buy Sep contract

Sep futures price:
$2.90/bu


actual basis:
$0.25 under
($2.65 $2.90)


$3.00/bushel
-$0.05
$2.95/bushel



$2.65/bushel
$0.35
$2.95/bushel


The hedge allows the producer to establish a range of expected market prices,

dependent only upon the difference between the expected basis and the actual basis at

harvest. If the basis remains constant, the final price received equals the initial expected

market price of $3.00/bushel. Any basis deviation from the original expected basis is added

to or subtracted from the expected market price to determine the net return (Hedging

Summary 1). The net return to the producer can also be calculated by adding the gain/loss

in the futures market to the cash price received from selling corn in the local market (Hedging

Summary 2). Brokerage or handling charges must also be deducted to determine net returns.

In this example, brokerage charges of 2 cents per bushel would reduce the net return to $2.93

per bushel.








This example illustrates how a change in basis affects the final price received by the

producer. The deviation of the actual basis in September from its expected value in the

previous March accounts for the market risk the corn producer faces. However, in this

example, basis movement (-$0.05) is significantly less than cash price movement (-$0.35).

Relying on cash market sales alone is risky since downward cash price movements may be

large and unpredictable. With hedging, price risk lies solely with basis movement and is no

longer dependent on the variability in the cash market. Since basis risk is significantly smaller

than cash price risk, hedging is an effective risk management tool for producers. In the

example, the producer was able to set a market price subject only to the variation in basis.

Note that the actual basis might have been smaller than expected as well. In that case, a

positive change in basis would have been added to the expected market price, resulting in a

higher expected net return.



BASIS TABLES AND GRAPHS

The remainder of this publication contains tables and graphs of historical corn basis for

Campbellton, Florida. There are two tables listing corn basis for Campbellton from January

1979 through December 1989. Table 1 contains weekly and average weekly basis for

September harvest contracts. Table 2 contains weekly basis and average weekly basis for

current nearby futures contracts. The basis figures in each table are calculated from Tuesday

futures prices from the Chicago Board of Trade as reported in the Wednesday issue of The

Wall Street Journal and actual prices received by farmers in Campbellton. Basis is reported

in cents. Historical cash prices for the 11-year period are graphed in Figure 1. The historical

basis for the September harvest contract is graphed in Figure 2. Note that in Figure 2, the

basis shows a fairly cyclical pattern of strengthening early in each year, then peaking right











before harvest, and weakening after harvest. Strengthening occurs as cash prices rise within

the crop year and peak near harvest. After harvest, cash prices fall in response to new

production entering the market and the basis weakens accordingly. The current contract basis

is graphed in Figure 3. The current contract basis is less variable than the harvest contract

basis, as can be shown by comparing Figure 2 and Figure 3.

The average basis is calculated as the difference between average cash prices and

average futures contract prices in Figure 4 and Figure 5. The basis units are on the right-hand

axis. The 11-year average weekly basis for harvest and current futures contracts is graphed

in Figure 6 and Figure 7, respectively. One standard deviation around the average basis is

included to show basis variability. In other words, 66 percent of the time the basis will fall

within the range presented in the figures. Note that the corn basis is over the futures price

until harvest approaches in July, reflecting a premium for cash prices in the Campbellton

market over futures prices.

The graph in Figure 6 illustrates how basis narrows as harvest approaches, reflecting

only costs of transportation. The basis begins to widen after harvest as it reflects storage and

interest costs for the following year. The basis then narrows at harvest as does its variability.

The corn basis shown in Figure 6 falls most often within a 25 cent range at harvest; between

10 cents over the futures price and 15 cents under the futures price.

The difference between basis risk and cash price risk is illustrated in Figure 8. The

basis is shown in the top half of the graph and its units appear on the right-hand axis. Cash

prices are shown in the bottom half of the graph, with units on the left-hand axis. Basis

variability for the harvest futures contract is approximately 40 cents, narrowing to 20 cents

at harvest. However, cash prices may vary as much as $1.20.









SUMMARY

The basis is the difference between local cash prices and futures contract prices at a

specific point in time. Storage and transportation costs are the primary factors affecting

basis, although other economic forces may also influence basis. Basis also reflects seasonal

cash price changes. This seasonality can be seen as the basis narrows around harvest and

widens afterwards. Fluctuations in local cash prices are risky for producers who sell

commodities in the cash market. An understanding of basis allows producers to effectively

utilize marketing strategies that minimize downside cash price risk. Hedging is one tool that

reduces the risk of adverse cash price movements. When a corn producer hedges on the

futures market, the final price received depends upon changes in the basis. Thus, basis

becomes the bottom-line determinant of the price received by farmers when they use risk

management marketing strategies in the futures market.
