The most startling surprise in the international economy during the 1980s has been the fulfillment of prophecies made five years ago—often voiced, seldom believed—that oil prices would decline significantly from their peak price of over $40 a barrel in 1980-81. Prices have, in fact, fallen to less than $12 a barrel on the spot market this past winter.
There is almost universal agreement that, on the whole, lower oil prices are beneficial to the world economy. But very low prices will pose very big problems. A further dramatic decline in oil prices will have a revolutionary impact on world politics and the international economy of a magnitude tantamount to that of the oil price increases in 1973-74 and 1979-80.
An explanation of the events that will be triggered by an oil price collapse depends, first, on an understanding of the peculiar nature of the international oil trade, so unlike that of other commodities, and second, on a determination of exactly what happened this past winter. Then the conditions that would allow a free-fall in oil prices can be defined. The consequences of such a price drop, including the implications for Western energy security, will become evident. And appropriate policy responses can be discussed.
