CPiFutures?
The previous Weekly Letter included
a discussion of the social costs and
benefits of a proposed futures market
for the Dow-jones industrial average.
In that article, we described two conditions that generally would establish
social gains from a futures market: (1)
a spot market characterized by large
price fluctuations; and (2) a large class
of risk-averse investors desirous of
covering their positions in a forward
market.

How wOI!.lIid futures work?
Consider for example a one-year
$100 contract. This contract would be
a promise to deliver one year from
now the dollar value of a bundle of
commodities currently valued at $100.
In this way it is similar to an ordinary
commodity future. Where a wheat future, for example, is a promise to deliver a certificate equal in value to a fixed
amount of wheat, a CPI future would
be a promise to deliver the value of
the CPI
basket of consumer
goods and services. In other words,
both parties to the contract would
agree that, regardless of any price
changes between the sale of the contract and its maturity, the seller would
provide the buyer with the money
necessary to buy the same bundle of
goods 'and services.
N

The Dow jones industrial average
possesses neither of these two characteristics, yet it is impossible to develop
a D 11futures market with social benefits. The essential elements would be
(1) the presence of substantial price risk
of some sort, and (2) a collection of investors willing to cover this risk in the
futures market. It is not necessary that
the price risk covered in the futures
market emanate from a single spot
market, nor is it necessary that the futures contract provide a hedge that is
totally free of risk.
The present article extends this discussion by examining another possible
type of contract - a futures market in
the Consumer Price Index (CPI). A CPI
futures market would have some of
the properties of the proposed Dowjones futures contract and some of
the characteristics of the older commodities futures market.

Suppose that both buyer and seller expected the rate of inflation to be 10
percent. Then both buyer and seller
would expect the contract to pay $110
at maturity. The actual dollar return on
the contract would be uncertain, however, because the inflation rate is always uncertain. For example, prices
might only rise by 5 percent over the
course of the year. This outcome
would benefit the seller, because the
buyer of the contract, expecting a high
10-percent inflation rate, would pay
too much for the contract. But in the
case of a 20-percent inflation rate, the

(continued on page 2)

advantage would go to the buyer,
who would receive $120 at maturity - ten dollars more than he had anticipated.
At the time the futures contract is issued there is very little difference between the futures contract and, say, a
one-year Treasury note. In both cases
expected rates of return would take
into account the expected rate of inflation. The difference is at maturity.
With a one-year Treasury note the
dollar rate of return would be locked in
but the holder would be exposed to
the risk that inflation would be higher
than he thought. With the CPI future
the holder would not be subject to this
risk. The real return would be locked
in because the CPI future is based on
the actual rate of inflation.
In the case of the Treasury note the risk
that actual inflation is greater than
pected inflation is borne by the security buyer. In the case of the CPI future
this risk is borne by the seller.
h

In understanding how this contract
would work, it is useful to distinguish
between unanticipated inflation and
anticipated inflation: All fixed income
assets,from Treasury securities to corporate bonds, include premiums reflecting the anticipated rate of inflation
and therefore protect against inflation
of this sort. But the CPI future would
protect against the risk of unanticipated inflation as well.

iRiskaverters
The CPIfutures contract, in one sense,
would be the opposite of a commodity contract. An ordinary commodity

2

futures contract allows individuals to
hedge against the risk of an uncertain
dollar return on a single commodity. A
wheat future, for example, enables a
grain-elevator owner to guarantee the
dollar value of his inventory, regardless of fluctuations in the spot market
for wheat. The CPI futures market, on
the other hand, would enable the
owner of a contract promising a fixed
amount of future dollars to hedge
against the risk of a declining value of
those dollars. The salaried employee,
for example, could ensure that he
would receive the amount of goods
and services his salary would buy at
the time he negotiated his salary. There
are, of course, large numbers of people interested in protecting themselves
against the risk of inflation.
In fact, one class of investors would
conceivably be required by law to
take a position in CPI futures. Pensionfund managers, now subject to the
prudent-investor standard of the Employee Retirement Income Security
Act of 1974 (ERISA)might be required
to include CPI future'Sin their portfolios.
Both sides of market
There might well be risk averters on
both sides of a CPHutures market.
Consider the case of a firm which has
negotiated a three-year wage settlement for fixed percentage increases in
wages each year, and which manufactures a product whose price rises in line
with the rate of inflation. Since the
costs of the firm are fixed in dollar
terms and its revenues are tied to inflation, low inflation could mean losses
for the firm. By taking a short position

in CPI futures, the firm could offset
those losses by gains from its futures
contracts.
A market in CPI futures also could provide a market solution to the problem
of contract indexation. Economists
who have proposed that wage contracts be written to provide for inflation-triggered automatic salary
increases probably would support this
concept because employers would
then have a way of offering inflationinsulated wage contracts without exposing their firms (and stockholders)
to the risk of future inflation.

Simiiarities: DBIand CPI
The CPI futures market, like the Dow
Jones futures market, would not have
a single spot market behind it. Instead,
both contracts would represent an
average of several spot market prices.
Yet in neither case would this be a de-

terrent to the creation of a futures market since the fluctuations in the
average price are enough to involve
substantial risk.
Both 0 JIfutures and CPI futures represent new concepts. But why haven't
they been considered up to now? One
possible explanation is that investors
only recently have become interested
in the opportunity to hedge provided
by these markets. The stock market's
dismal performance over the past
decade has finally led investors to demand protection against conditions
that lead to weak stock prices - hence
their interest in OJI futures. And the
highly variable inflation of the 1970's
has increased investors' perception of
the desirability of protecting against
unanticipated inflation - hence their
interest in CPI futures. These futures
markets thus provide a way of dealing
with investors' legitimate concerns.

the effects of expectations formation on some basic propositions of macroeconomics, and second, the behavior of financial institutions over the business
cycle. Five research papers by West Coast academic economists (along with
discussion notes) are included in the volume. The Proceedingsare aimed primarily at an audience of financial analysts and academic economists . . . Free copies
