Oil’s global regime change
The embargo’s disruptive power was due to two key factors: OPEC’s dominance of world oil supply, and oil’s supremacy in the global energy mix.
Prior to the embargo, oil fueled almost half of total energy consumption in the United States (47.5%) and worldwide (49%). While OPEC countries produced more than half (53%) of global oil, the concessions were operated by Western oil majors.
After the embargo, producer states took over. Control of global oil production passed from Western oil giants like Shell and Exxon to newly formed national oil companies.
As a result, a torrent of cash from oil sales poured into Middle Eastern countries where rudimentary services like electricity were still being built out. Oil revenues in Saudi Arabia jumped fortyfold between 1965 and 1975, from US$655 million to $26.7 billion. These countries also amassed new geopolitical power.
How the oil price spike played out in the West
In the West, price increases wreaked havoc on economies and transport systems that were far less efficient than today. Inflation soon boiled over into “stagflation,” a combination of economic stagnation and high inflation. Misguided policies, including gasoline price controls and rationing, exacerbated shortages, creating long lines at service stations and emboldening gasoline thieves.
America saw a pell-mell downsizing of gas-guzzling vehicles and a simultaneous ramping up of imports of fuel-efficient Japanese cars. Drivers obsessed over miles per gallon, and the U.S. government imposed corporate average fuel economy, or CAFE, standards, aimed at saving fuel by requiring automakers to sell more fuel-efficient cars.
Western oil companies, kicked out of the Middle East and other oil regions, pivoted to more difficult terrain: the offshore Gulf of Mexico and North Sea, and the Arctic regions of northern Alaska.
As scholars of energy policy, we have long studied the embargo’s spillover effects on the global economy and political systems. These outcomes are a central theme in Jim Krane’s 2019 book “Energy Kingdoms.” On the embargo’s 50th anniversary, Oct. 17, 2023, King Faisal’s son, the former Saudi Ambassador to Washington Prince Turki Al Faisal, is joining us for a conference at Rice University’s Baker Institute to discuss the still-valid lessons of the Arab oil embargo.
50 years later, new pressures
Fifty years on, markets have changed. But oil continues to be the world’s dominant energy source.
On one hand, crude oil use has grown dramatically. Global supply has risen from less than 60 million barrels per day in 1973 to nearly 94 million barrels per day in 2022. Motor fuel prices are still a critical input to inflation; we calculate that the increase in gasoline prices in 2022 cost the average American household roughly $1,000.
On the other hand, OPEC’s importance – and oil’s share of the global energy mix – has declined. OPEC’s 13 members account for just 36% of global oil production today. The high oil prices caused by the 1973 embargo created incentives for oil drillers to diversify toward new sources of oil and develop substitute fuels to replace oil.
Within 15 years of the embargo, production outside OPEC increased by a massive 14 million barrels per day. Oil from Alaska and the Gulf of Mexico helped stabilize U.S. production. Later, the shale revolution turned the United States into the world’s largest producer and a net exporter of oil, capping a 50-year quest.
The world has also become much more efficient, reducing the amount of oil needed to maintain the same activity. Global per-capita oil use per dollar of gross domestic product has fallen by a massive 60% since 1973, our calculations show.
But, as in 1973, energy security concerns are back at the top of national agendas.
Russia’s 2022 invasion of Ukraine reprised the risks of energy “weaponization.” Europe, in particular, has been hurt by overdependence on Russian natural gas and has raced to shift its energy sources. The Israel-Hamas war that began on Oct. 8, 2023, has not yet ignited retaliatory responses from Arab governments, and the initial impact on oil has been minimal, but geopolitical effects from such a large event could still roil markets.
Energy security itself is also being altered. The transition to renewable energy sources like wind and solar insulates consumers from most supply chain risks. Electric vehicles likewise protect owners from swinging oil prices. So, while crucial materials can still be manipulated by governments, shortages and price spikes mainly affect component manufacturers and their investors. If supplies are bottlenecked long enough, the energy transition could be delayed.
Like the embargo 50 years ago, today’s crises have rendered the future of energy massively uncertain. Changes in the global energy mix, especially the rapid growth of electric vehicles, could weaken the importance of oil and the cartel that oversees it.
As former Saudi oil minister Ahmed Zaki Yamani was reported to have said a quarter-century ago: “The Stone Age did not end for lack of stone, and the oil age will end long before the world runs out of oil.”
