The price of oil is rarely stable, but certain moments in history have sent shockwaves through the global economy, reshaping industries and international relations. From geopolitical conflicts to economic downturns, a series of crises have underscored the world’s dependence on this essential commodity. Understanding these past disruptions – the oil shocks of 1973, 1979, 1990, 2008, and 2022 – is crucial to navigating the complexities of today’s energy landscape and anticipating future vulnerabilities. These events demonstrate how quickly global energy markets can be thrown into turmoil, impacting everything from the cost of gasoline to international political stability.
The modern era of oil price volatility began with the 1973 Yom Kippur War. The conflict, fought between Israel and a coalition of Arab states led by Egypt and Syria, triggered a coordinated response from oil-producing nations. In retaliation for Western support of Israel, the Organization of Arab Petroleum Exporting Countries (OAPEC) imposed an embargo on oil shipments to the United States and other allied nations, whereas simultaneously increasing prices. This action wasn’t simply about restricting supply; it was a calculated move to leverage oil as a political weapon.
The First Shockwave: The 1973 Oil Crisis
The impact was immediate and dramatic. Within months, the price of crude oil quadrupled, soaring from around $3 to $12 per barrel. Jean-Thomas Bernard, a professor of economics at the University of Ottawa, illustrates the magnitude of the increase, stating, “In today’s context, before the war in Iran, the price was around $70. It’s as if it went to $280.” The effects weren’t perceived as temporary. The surge in oil prices fueled a period of “stagflation” – a rare and painful combination of economic slowdown, widespread price increases, and high unemployment. Canada experienced a recession alongside an inflation rate that peaked at 12.7% in December 1974, according to Statistics Canada data .
Yvan Cliche, an energy specialist at the Centre d’études et de recherches internationales at the University of Montreal, recalls the psychological impact: “It was a big psychological shock for Western countries, especially the United States, with lines at gas stations.” The crisis prompted the creation of the International Energy Agency (IEA) in 1974, designed to coordinate energy policies and ensure energy security. Today, the IEA comprises 32 member states and maintains strategic petroleum reserves totaling 1.2 billion barrels.
From Revolution to War: 1979 and 1990
The 1970s weren’t finished with oil shocks. The 1979 Iranian Revolution, which ousted the Shah and established an Islamic Republic, sent prices soaring again. Iran, then the world’s fourth-largest oil producer, drastically reduced its exports. This disruption was compounded in September 1980 by the outbreak of the Iran-Iraq War, further destabilizing the region. Between 1978 and 1981, Iranian oil production plummeted by 75%, while Iraqi production fell by 66%, as documented by Our World in Data . Global oil prices nearly tripled.
The resulting stagflation returned, and Canada again faced economic hardship. Inflation reached nearly 13% in July 1981, prompting the Bank of Canada to raise interest rates to a staggering 21%, severely braking economic growth. In response, the Canadian government implemented the National Energy Program (NEP), a highly interventionist policy aimed at isolating Canada from global market forces and controlling prices. Bernard describes the program as an attempt to “Canadianize” the sector, but it proved deeply unpopular with Western provinces and ultimately “excessively costly,” creating a lasting deficit.
Barely two years after the end of the Iran-Iraq War, another crisis erupted in the Persian Gulf. In 1990, Iraq invaded Kuwait, a significant oil producer. The United States, under President George H.W. Bush, led a coalition to liberate Kuwait. “It had an impact on Kuwait, which was a fairly important producer,” Bernard notes. Production in both Kuwait and Iraq collapsed, sending prices higher. The United States’ motivations, Cliche points out, were inextricably linked to oil supply, as the country relied heavily on the resource and didn’t want Iraq to become a dominant market player. This concern resurfaced during the 2003 invasion of Iraq.
In 1991, the IEA tapped into its strategic reserves for the first time. This emergency measure was repeated in 2005 following Hurricane Katrina, in 2011 due to unrest in Libya, and twice in 2022 following Russia’s invasion of Ukraine. Most recently, on March 11th, G7 countries agreed to release 400 million barrels of oil to alleviate market pressures related to the ongoing conflict .
The Financial Crisis and the Shale Revolution
The crisis of 2008 differed in origin. It wasn’t a geopolitical event, but rather a financial meltdown triggered by the collapse of the U.S. Housing bubble and the subsequent failure of financial institutions. However, the global economic recession it caused still impacted oil prices. The price of a barrel of oil doubled in a single year, peaking at $147 in July 2008. Cliche attributes this surge to the rapid industrialization of China, which became “the world’s factory” and fueled unprecedented demand for oil.
The spike proved short-lived. By December 2008, prices had fallen below $40 per barrel. This decline coincided with the rise of shale oil and gas production in the United States, driven by advancements in hydraulic fracturing (“fracking”). This technological breakthrough dramatically increased oil supply, transforming the U.S. Into the world’s leading producer.
Russia’s Invasion of Ukraine and the Current Landscape
The most recent major disruption came with Russia’s invasion of Ukraine in February 2022. Western sanctions imposed on Russia, a major oil producer, aimed to cripple its economy. Oil prices initially jumped to around $120 per barrel. However, Russia redirected its exports to China and India, which then facilitated the flow of oil to Europe, mitigating the initial shock. “We benefited greatly from the flexibility” of supply chains, Bernard observes, noting that oil is now transported on massive tankers that can be rerouted quickly.
While economies are less reliant on oil than in the past, increasing their resilience to price shocks, Cliche cautions that the decline of oil is relative, not absolute. Global oil consumption remains at record levels, and the resource remains critical for transportation. “That’s why the impacts remain significant for the economy whenever there’s an increase in prices.”
Looking ahead, the energy transition and geopolitical factors will continue to shape the oil market. While renewable energy sources are gaining prominence, oil will likely remain a significant part of the global energy mix for the foreseeable future. The IEA will continue to play a vital role in monitoring market developments and coordinating responses to potential disruptions. The next key event to watch will be the OPEC+ meetings in the coming months, as decisions regarding production levels will significantly influence global oil prices.
