| Summary: | Futures markets play an important role in the price discovery and forward pricing
of agricultural commodities. Agricultural product prices have been found to be
particularly volatile and susceptible to sharp fluctuations which expose producers and
traders to increased risks in handling these products. For countries like Malaysia which
depend on commodity earnings for a substantial portion of their inflow of foreign
exchange, severe fluctuations in prices could have unfavourable effects on the economy.
The effects of futures prices on cash prices have been the subject of much
research in recent years. The contention is that if the futures market is efficient, then
futures prices should provide unbiased forecasts of cash prices in order to facilitate
optimal production and storage decisions. Many empirical studies have in fact shown
that futures trading leads to more efficient spot markets. The development of futures
markets in Malaysia was to fulfill the need for an efficient pricing and hedging mechanism for Malaysia's primary commodities. Whether that objective has been
fulfilled after twelve years since the setting up of the Kuala Lumpur Commodity
Exchange (KLCE) is the subject of this study. Over the years, the commodity base of the
exchange has expanded from crude palm oil (CPO) to rubber, tin, cocoa and refined,
bleached and deodorized (rbd) palm olein. The pricing efficiency of the CPO futures
market is evaluated in this study since it has important inferences for the later established
futures markets. The hypothesis tested is whether the futures market is informationally
efficient. Comparisons are made with cocoa futures which were introduced only recently
on the exchange and which represents another commodity where Malaysia has had to
depend on world markets {or domestic price determination.
This study evaluates pricing efficiency by using the cointegration approach which
examines the nature of the relationship between cash and futures prices for a commodity.
This method overcomes the problems associated with previous methods on testing futures
market efficiency. Assessments on the efficiency of the market are based on the degree
of divergence and the speed of adjustment between cash and futures prices. Daily prices
over the period 1981 to 1992 were used for CPO and a two year period between 1989
and 1990 were covered for cocoa.The results obtained indicate that in the case of the CPO market, with only one
exception, there was generally cointegration between cash and futures prices for the
period studied, implying pricing efficiency in the market. It was also found that a mechanism existed which brought cash and futures prices into alignment whenever they
diverged. The evidence also points to the dependence of cash markets on future markets
for price indications. The only exception was in 1984, and this was the year in which
the KLCE was embroiled in a crisis. The structural defects of the market appears to
have affected the pricing performance to such an extent that futures and cash prices went
out of alignment. In the case of the cocoa market, the results indicate that futures and
cash prices were cointegrated and there was pricing efficiency. But the subsequent
decline of trading interest in the market indicates that there were structural defects which
had led to a loss of confidence in the market and affected liquidity. This study therefore
underlines the possible influence of market structure on the pricing performance of the
market. |
