Estimates are derived of the potential variability of world wheat prices and the sources of this variability. These indicate a sizable increase in the probability of large short-run fluctuations in price. The bulk of this variability is due to fluctuations in the domestic grain production of developing and centrally-planned economies. However, most market participants are unresponsive to short-run changes in world price, and transmit a substantial amount of domestic variability to the world market. The key factor in world price stability is the short-run responsiveness of wheat exports from the USA. It is likely that both the physical and policy factors that have contributed to increased variability will persist.
