Crude Volatility: The History and the Future of Boom-Bust Oil Prices

by Robert McNally

Quick Summary

A comprehensive historical analysis arguing that oil price volatility is the natural state of the petroleum market, not an aberration. McNally traces the critical role of swing producers -- from Standard Oil through the Texas Railroad Commission to OPEC -- in maintaining price stability, and argues that the disappearance of effective supply management since the mid-2000s has returned oil to its inherent boom-bust pattern, with profound implications for the global economy and geopolitics.

Detailed Summary

Robert McNally's "Crude Volatility," published as part of Columbia University's Center on Global Energy Policy Series, presents a historical thesis with significant contemporary implications: that oil prices are inherently prone to extreme volatility, and that the periods of relative price stability in oil market history were not natural but were achieved through active supply management by dominant producers. The book includes two novel historical data sets -- a continuous market-based price series for U.S. crude extending back to 1859 and historical data on spare production capacity.

Part One covers the period from 1859 to 1972, beginning with the chaotic early decades of the American oil industry when prices fluctuated wildly between boom and bust. The initial discovery era saw prices collapse as new wells flooded the market, then spike as demand outran supply. John D. Rockefeller's Standard Oil achieved a degree of market stability through monopolistic control of refining and transportation infrastructure, but its dissolution by the Supreme Court in 1911 removed this stabilizing mechanism.

The book explains why oil is particularly prone to boom-bust cycles: inelastic supply and demand in the short run (neither producers nor consumers can quickly adjust to price changes), long lead times for new production, the exhaustible nature of individual wells, and the tendency of speculative investment to amplify cycles. These characteristics create a market where small shifts in the supply-demand balance produce large price movements.

The chapter on the Texas era (1934-1972) describes how the Texas Railroad Commission, through production quotas (prorationing), effectively served as a swing producer that could increase or decrease output to stabilize prices. This system, combined with international agreements among the "Seven Sisters" (major oil companies), maintained relatively stable prices for nearly four decades.

Part Two covers the OPEC era from 1973 to 2008, tracing how OPEC, particularly Saudi Arabia, inherited the swing producer role from Texas as U.S. production peaked and began declining. The 1973 oil embargo, the 1979 Iranian Revolution price spike, the 1986 price collapse when Saudi Arabia abandoned its swing producer role, and the subsequent decades of OPEC's attempts to manage supply are analyzed through the lens of swing producer theory.

The critical argument emerges in Part Two's later chapters: beginning in the mid-2000s, OPEC's spare capacity -- the key mechanism for moderating price swings -- shrank to historically low levels as surging Asian demand, particularly from China, consumed the buffer. The result was the price spike to $147/barrel in 2008, the subsequent crash, and the volatile pattern that has characterized oil markets since, including the dramatic boom-bust cycle driven by the unexpected emergence of U.S. shale production.

McNally concludes that without a willing and able swing producer, the oil market will continue to experience the kind of extreme price volatility that characterized its earliest decades, with significant implications for economic stability, energy policy, and geopolitical relations.
