1973 oil crisis
The 1973 oil crisis began in October 1973 when the members of the Organization of Arab Petroleum Exporting Countries proclaimed an oil embargo. The embargo was targeted at nations perceived as supporting Israel during the Yom Kippur War. The initial nations targeted were Canada, Japan, the Netherlands, the United Kingdom and the United States with the embargo also later extended to Portugal, Rhodesia and South Africa. By the end of the embargo in March 1974, the price of oil had risen from US$3 per barrel to nearly $12 globally; US prices were significantly higher. The embargo caused an oil crisis, or "shock", with many short- and long-term effects on global politics and the global economy. It was later called the "first oil shock", followed by the 1979 oil crisis, termed the "second oil shock."
American production decline
By 1969, American domestic output of oil could not keep pace with increasing demand; in 1925, oil had accounted for one-fifth of American energy use; by the time World War II started one-third of America's energy needs was met by oil. Oil started to replace coal as a preferred fuel source — it was used to heat homes and generate electricity, and it was the only fuel that could be used for air transport. In 1920, American oilfields accounted for nearly two-thirds of global oil production. In 1945, US production had increased to just over two-thirds. The US had been able to meet its own energy needs independently in the decade between 1945 and 1955, but was importing 350 million barrels per year by the late 1950s, mostly from Venezuela and Canada. In 1973, US production had declined to 16.5% of global output.
The costs of producing oil in the Middle East were low enough that companies could turn a profit despite the US tariff on oil imports. This hurt domestic oil producers in places like Texas and Oklahoma who had been selling oil at tariff-supported prices and now had to compete with cheap oil from the Persian Gulf region. The first American firms to take advantage of low production costs in the Middle East were Getty, Standard Oil of Indiana, Continental Oil and Atlantic Richfield. In 1959, President Dwight D. Eisenhower said "As long as Middle Eastern oil continues to be as cheap as it is, there is probably little we can do to reduce the dependence of Western Europe on the Middle East." Eventually, at the behest of independent American producers, Eisenhower imposed quotas on foreign oil that would stay in place between 1959 and 1973. Critics called it the "drain America first" policy. Some scholars believe the policy contributed to the decline of domestic US oil production in the early 1970s. While US oil production declined, domestic demand was increasing at the same time leading to inflation and a steadily rising consumer price index between 1964 and 1970.
US surplus production capacity had declined from 4 million bpd to around 1 million bpd between 1963 and 1970, increasing American dependence on foreign oil imports. When Richard Nixon took office in 1969, he assigned George Shultz to head a committee to review the Eisenhower-era quota program — Shultz's committee recommended that the quotas be abolished and replaced with tariffs but Nixon decided to keep the quotas due to vigorous political opposition. Nixon imposed a price ceiling on oil in 1971 as demand for oil was increasing and production was declining, which increased dependence on foreign oil imports as consumption was bolstered by low prices. In 1973 Nixon announced the end of the quota system. Between 1970 and 1973 US imports of crude oil had nearly doubled, reaching 6.2 million barrels per day in 1973. Until 1973, an abundance of oil supply had kept the market price of oil lower than the posted price.
The Organization of the Petroleum Exporting Countries (OPEC), was founded by five oil producing countries at a Baghdad conference on September 14, 1960. The five founding members of OPEC were Venezuela, Iraq, Saudi Arabia, Iran and Kuwait. OPEC was organized after the oil companies slashed the posted price of oil, but the posted price of oil remained consistently higher than the market price of oil between 1961 and 1972.
In 1963, the Seven Sisters controlled 86% of the oil produced by OPEC countries, but by 1970 the rise of "independent oil companies" had decreased their share to 77%. The entry of three new oil producers—Algeria, Libya and Nigeria—meant that by 1970 eighty-one oil companies were doing business in the Middle East.
In the early 1960s Libya, Indonesia and Qatar joined OPEC. OPEC was generally regarded as ineffective until political turbulence in Libya and Iraq strengthened their position in 1970. Additionally, increasing Soviet influence provided oil producing countries with alternative means of transporting oil to markets.
Under the Tehran Price Agreement of 1971 the posted price of oil was increased and, due to a decline in the value of the US dollar relative to gold, certain anti-inflationary measures were enacted.
In September 1973 Richard Nixon said, "Oil without a market, as Mr. Mossagedh learned many, many years ago, does not do a country much good," referring to the 1951 nationalization of the Iranian oil industry, but between October 1973 and February 1974 the OPEC countries raised by posted price fourfold to nearly $12.
End of Bretton Woods
On August 15, 1971, the United States unilaterally pulled out of the Bretton Woods Accord. The US abandoned the Gold Exchange Standard whereby the value of the dollar had been pegged to the price of gold and all other currencies were pegged to the dollar, whose value was left to "float" (rise and fall according to market demand). Shortly thereafter, Britain followed, floating the pound sterling. The other industrialized nations followed suit with their respective currencies. Anticipating that currency values would fluctuate unpredictably for a time, the industrialized nations increased their reserves (by expanding their money supplies) in amounts far greater than before. The result was a depreciation of the dollar and other industrialized nations' currencies. Because oil was priced in dollars, oil producers' real income decreased. In September 1971, OPEC issued a joint communiqué stating that, from then on, they would price oil in terms of a fixed amount of gold.
This contributed to the "Oil Shock". After 1971, OPEC was slow to readjust prices to reflect this depreciation. From 1947 to 1967, the dollar price of oil had risen by less than two percent per year. Until the oil shock, the price had also remained fairly stable versus other currencies and commodities. OPEC ministers had not developed institutional mechanisms to update prices in sync with changing market conditions, so their real incomes lagged. The substantial price increases of 1973–1974 largely returned their prices and corresponding incomes to Bretton Woods levels in terms of commodities such as gold.
The "oil weapon"
Arab oil producing countries had attempted to use oil as leverage to influence political events on two prior occasions—the first was the Suez Crisis in 1956 when the United Kingdom, France and Israel invaded Egypt. During the conflict the Syrians sabotaged both the Trans-Arabian Pipeline and the Iraq–Baniyas pipeline, which disrupted the supply of oil to Western Europe. The second instance was when war broke out between Egypt and Israel in 1967, but despite continued Egyptian and Syrian enmity against Israel, the embargo lasted only a few months. Most scholars agree that the 1967 embargo was ineffective.
Although some members of Organization of Arab Petroleum Exporting Countries (OAPEC) supported the use of oil as a weapon to influence the political outcome of the Arab–Israeli conflict, Saudi Arabia had traditionally been the strongest supporter of separating oil from politics. The Saudis were wary of the tactic due to the availability of oil from non-Arab oil producing countries, and in the decades leading up to the crisis, the region's conservative monarchies had grown dependent on Western support to ensure their continued survival as Nasserism gained traction. On the other hand, Algeria, Iraq and Libya had strongly supported the use of oil as a weapon in the conflict. Arab newspapers like the Egyptian Al-Ahram, Lebanese An-Nahar and Iraqi Al-Thawra had historically been supportive of the use of oil as a weapon.
On October 6, 1973 Egypt attacked the Bar Lev Line in the Sinai Peninsula and Syria launched an offensive in the Golan Heights, both of which had been occupied by Israel during the 1967 Six-Day War. On October 12, 1973, US president Richard Nixon authorized Operation Nickel Grass, a strategic airlift to deliver weapons and supplies to Israel in order to replace its materiel losses, after the Soviet Union began sending arms to Syria and Egypt. The following day, on October 17, Arab oil producers cut production by 5% and instituted an oil embargo against Israel's allies: the United States, Netherlands, Rhodesia, South Africa, and Portugal. Saudi Arabia only consented to the embargo after Nixon's promise of $2.2 billion in military aid to Israel. The embargo was accompanied by gradual monthly production cuts—by December, production had been cut to 25% of September levels. This contributed to a global recession and increased tension between the United States and European allies who faulted the US for provoking an embargo by providing assistance to Israel. OAPEC demanded a complete Israeli withdrawal from all territories beyond the 1949 Armistice border.
Effectiveness of embargo
The embargo lasted from October 1973 to March 1974. Since Israeli forces did not withdraw to the 1949 Armistice Line, the majority of scholars believe the embargo was a failure. Roy Licklieder, in his 1988 book Political Power and the Arab Oil Weapon, concluded the embargo was a failure because the countries that were targeted by the embargo did not change their policies on the Arab–Israeli conflict. Licklieder believed that any long term changes were caused by the OPEC increase in the posted price of oil, and not the OAPEC embargo. Daniel Yergin, on the other hand, has said that the embargo "remade the international economy".
Over the long term, the oil embargo changed the nature of policy in the West towards increased exploration, alternative energy research, energy conservation and more restrictive monetary policy to better fight inflation.

Immediate economic effects
The effects of the embargo were immediate. OPEC forced oil companies to increase payments drastically. The price of oil quadrupled by 1974 from US$3 to nearly US$12 per barrel (75 US$/m3), equivalent in 2018 dollars to a price rise from $17 to $61 per barrel.
This price increase had a dramatic effect on oil exporting nations, for the countries of the Middle East who had long been dominated by the industrial powers seen to have taken control of a vital commodity. The oil-exporting nations began to accumulate vast wealth.
Some of the income was dispensed in the form of aid to other underdeveloped nations whose economies had been caught between higher oil prices and lower prices for their own export commodities, amid shrinking Western demand. Much went for arms purchases that exacerbated political tensions, particularly in the Middle East. Saudi Arabia spent over 100 billion dollars in the ensuing decades for helping spread its fundamentalist interpretation of Islam, known as Wahhabism, throughout the world, via religious charities such al-Haramain Foundation, which often also distributed funds to violent Sunni extremist groups such as Al-Qaeda and the Taliban.
Control of oil became known as the "oil weapon." It came in the form of an embargo and production cutbacks from the Arab states. The weapon was aimed at the United States, Great Britain, Canada, Japan and the Netherlands. These target governments perceived that the intent was to push them towards a more pro-Arab position. Production was eventually cut by 25%. However, the affected countries did not undertake dramatic policy changes.
In the United States, scholars argue that there already existed a negotiated settlement based on equality between both parties prior to 1973. The possibility that the Middle East could become another superpower confrontation with the USSR was of more concern to the US than oil. Further, interest groups and government agencies more worried about energy were no match for Kissinger's dominance. In the US production, distribution and price disruptions "have been held responsible for recessions, periods of excessive inflation, reduced productivity, and lower economic growth." Some researchers regard the 1973 "oil price shock" and the accompanying 1973–74 stock market crash as the first discrete event since the Great Depression to have a persistent effect on the US economy.
The embargo had a negative influence on the US economy by causing immediate demands to address the threats to U.S. energy security. On an international level, the price increases changed competitive positions in many industries, such as automobiles. Macroeconomic problems consisted of both inflationary and deflationary impacts. The embargo left oil companies searching for new ways to increase oil supplies, even in rugged terrain such as the Arctic. Finding oil and developing new fields usually required five to ten years before significant production.
OPEC-member states raised the prospect of nationalization of oil company holdings. Most notably, Saudi Arabia nationalized Aramco in 1980 under the leadership of Saudi oil minister Ahmed Zaki Yamani. As other OPEC nations followed suit, the cartel's income soared. Saudi Arabia undertook a series of ambitious five-year development plans. The biggest began in 1980, funded at $250 billion. Other cartel members also undertook major economic development programs.
The average US retail price of a gallon of regular gasoline rose 43% from 38.5¢ in May 1973 to 55.1¢ in June 1974. State governments asked citizens not to put up Christmas lights. Oregon banned Christmas and commercial lighting altogether. Politicians called for a national gasoline rationing program. Nixon asked gasoline retailers to voluntarily not sell gasoline on Saturday nights or Sundays; 90% of gas station owners complied, which produced long queues of motorists wanting to fill up their cars while they could.
The embargo was not uniform across Europe. Of the nine members of the European Economic Community (EEC), the Netherlands faced a complete embargo, the UK and France received almost uninterrupted supplies (having refused to allow America to use their airfields and embargoed arms and supplies to both the Arabs and the Israelis), while the other six faced partial cutbacks. The UK had traditionally been an ally of Israel, and Harold Wilson's government supported the Israelis during the Six-Day War. His successor, Ted Heath, reversed this policy in 1970, calling for Israel to withdraw to its pre-1967 borders.
The EEC was unable to achieve a common policy during the first month of the War. It issued a statement on November 6, after the embargo and price rises had begun. It was widely viewed as pro-Arab supporting the Franco-British line on the war. OPEC duly lifted its embargo from all EEC members. The price rises had a much greater impact in Europe than the embargo.
Despite being relatively unaffected by the embargo, the UK nonetheless faced an oil crisis of its own—a series of strikes by coal miners and railroad workers over the winter of 1973–74 became a major factor in the change of government. Heath asked the British to heat only one room in their houses over the winter. The UK, Germany, Italy, Switzerland and Norway banned flying, driving and boating on Sundays. Sweden rationed gasoline and heating oil. The Netherlands imposed prison sentences for those who used more than their ration of electricity.
A few months later, the crisis eased. The embargo was lifted in March 1974 after negotiations at the Washington Oil Summit, but the effects lingered throughout the 1970s. The dollar price of energy increased again the following year, amid the weakening competitive position of the dollar in world markets.
Price controls and rationing
Price controls exacerbated the crisis in the US. The system limited the price of "old oil" (that which had already been discovered) while allowing newly discovered oil to be sold at a higher price to encourage investment. Predictably, old oil was withdrawn from the market, creating greater scarcity. The rule also discouraged development of alternative energies. The rule had been intended to promote oil exploration. Scarcity was addressed by rationing (as in many countries). Motorists faced long lines at gas stations beginning in summer 1972 and increasing by summer 1973.
In 1973, Nixon named William E. Simon as the first Administrator of the Federal Energy Office, a short-term organization created to coordinate the response to the embargo. Simon allocated states the same amount of domestic oil for 1974 that each had consumed in 1972, which worked for states whose populations were not increasing. In other states, lines at gasoline stations were common. The American Automobile Association reported that in the last week of February 1974, 20% of American gasoline stations had no fuel.
Odd–even rationing allowed vehicles with license plates having an odd number as the last digit (or a vanity license plate) to buy gas only on odd-numbered days of the month, while others could buy only on even-numbered days.
In some states, a three-color flag system was used to denote gasoline availability at service stations—green for unrationed availability, yellow for restricted/rationed sales and red for out of stock.
Rationing led to violent incidents, when truck drivers chose to strike for two days in December 1973 over the limited supplies Simon had allocated for their industry. In Pennsylvania and Ohio, non-striking truckers were shot at by striking truckers, and in Arkansas, trucks of non-strikers were attacked with bombs.
America had controlled the price of natural gas since the 1950s. With the inflation of the 1970s, the price was too low to encourage the search for new reserves. America's natural gas reserves dwindled from 237 trillion in 1974 to 203 trillion[clarification needed] in 1978. The price controls were not changed despite president Gerald Ford's repeated requests to Congress.
Conservation and reduction in demand
To help reduce consumption, in 1974 a national maximum speed limit of 55 mph (about 88 km/h) was imposed through the Emergency Highway Energy Conservation Act. Development of the Strategic Petroleum Reserve began in 1975, and in 1977 the cabinet-level Department of Energy was created, followed by the National Energy Act of 1978. On November 28, 1995, Bill Clinton signed the National Highway Designation Act, ending the federal 55 mph (89 km/h) speed limit, allowing states to restore their prior maximum speed limit.
Year-round daylight saving time was implemented from January 6, 1974, to October 27, 1975, with a break between October 27, 1974 and February 23, 1975, when the country observed standard time. The move spawned significant criticism because it forced many children to travel to school before sunrise. The prior rules were restored in 1976.
The crisis prompted a call to conserve energy, most notably a campaign by the Advertising Council using the tagline "Don't Be Fuelish". Many newspapers carried advertisements featuring cut-outs that could be attached to light switches, reading "Last Out, Lights Out: Don't Be Fuelish."
By 1980, domestic luxury cars with a 130-inch (3.3 m) wheelbase and gross weights averaging 4,500 pounds (2,041 kg) were no longer made. The automakers had begun phasing out the traditional front engine/rear wheel drive layout in compact cars in favor of lighter front engine/front wheel drive designs. A higher percentage of cars offered more efficient 4-cylinder engines. Domestic auto makers also began offering more fuel efficient diesel powered passenger cars as well.
Although not regulated by the new legislation, auto racing groups voluntarily began conserving. In 1974, NASCAR reduced all race distances by 10%; the 24 Hours of Daytona and the 12 Hours of Sebring race were cancelled.
Alternative energy sources
The energy crisis led to greater interest in renewable energy, nuclear power and domestic fossil fuels. According to Peter Grossman, American energy policies since the crisis have been dominated by crisis-mentality thinking, promoting expensive quick fixes and single-shot solutions that ignore market and technology realities. He wrote that instead of providing stable rules that support basic research while leaving plenty of scope for entrepreneurship and innovation, congresses and presidents have repeatedly backed policies which promise solutions that are politically expedient, but whose prospects are doubtful.
Israel was one of the few countries unaffected by the embargo, since it could extract sufficient oil from the Sinai. But to supplement Israel's over-taxed power grid, Harry Zvi Tabor, the father of Israel's solar industry, developed the prototype for a solar water heater now used in over 90% of Israeli homes.
The crisis was a major factor in shifting Japan's economy away from oil-intensive industries. Investment shifted to industries such as electronics. Japanese auto makers also benefited from the crisis. Increased fuel costs allowed their small, fuel-efficient models to gain market share from the "gas-guzzling" American competition. This triggered a drop in American auto sales that lasted into the 1980s.
Western central banks decided to sharply cut interest rates to encourage growth, deciding that inflation was a secondary concern. Although this was the orthodox macroeconomic prescription at the time, the resulting stagflation surprised economists and central bankers. The policy is now considered by some to have deepened and lengthened the adverse effects of the embargo. Recent research claims that in the period after 1985 the economy became more resilient to energy price increases.
The price shock created large current account deficits in oil-importing economies. A petrodollar recycling mechanism was created, through which OPEC surplus funds were channeled through the capital markets to the West to finance the current account deficits. The functioning of this mechanism required the relaxation of capital controls in oil-importing economies. It marked the beginning of an exponential growth of Western capital markets.
In 1974, seven of the fifteen top Fortune 500 companies were oil companies, falling to four in 2014.
The crisis had a major impact on international relations and created a rift within NATO. Some European nations and Japan sought to disassociate themselves from United States foreign policy in the Middle East to avoid being targeted by the boycott. Arab oil producers linked any future policy changes to peace between the belligerents. To address this, the Nixon Administration began multilateral negotiations with the combatants. They arranged for Israel to pull back from the Sinai Peninsula and the Golan Heights. By January 18, 1974, US Secretary of State Henry Kissinger had negotiated an Israeli troop withdrawal from parts of the Sinai Peninsula. The promise of a negotiated settlement between Israel and Syria was enough to convince Arab oil producers to lift the embargo in March 1974. and again during the 1979 energy crisis.
America's Cold War policies suffered a major blow from the embargo. They had focused on China and the Soviet Union, but the latent challenge to US hegemony coming from the third world became evident.
In 2004, declassified documents revealed that the U.S. was so distraught by the rise in oil prices and being challenged by under-developed countries that they briefly considered military action to forcibly seize Middle Eastern oilfields in late 1973. Although no explicit plan was mentioned, a conversation between U.S. Secretary of Defense James Schlesinger and British Ambassador to the United States Lord Cromer revealed Schlesinger had told him that "it was no longer obvious to him that the U.S. could not use force." British Prime Minister Edward Heath was so worried by this prospect that he ordered a British intelligence estimate of U.S. intentions, which concluded America "might consider it could not tolerate a situation in which the U.S. and its allies were at the mercy of a small group of unreasonable countries," and that they would prefer a rapid operation to seize oilfields in Saudi Arabia and Kuwait, and possibly Abu Dhabi if military action was decided upon. Although the Soviet response to such an act would likely not involve force, intelligence warned "the American occupation would need to last 10 years as the West developed alternative energy sources, and would result in the 'total alienation' of the Arabs and much of the rest of the Third World."
Western Europe began switching from pro-Israel to more pro-Arab policies. This change strained the Western alliance. The US, which imported only 12% of its oil from the Middle East (compared with 80% for the Europeans and over 90% for Japan), remained staunchly committed to Israel. The percentage of U.S. oil which comes from the nations bordering the Persian Gulf remained steady over the decades, with a figure of a little more than 10% in 2008.
With the embargo in place, many developed countries altered their policies regarding the Arab-Israeli conflict. These included the UK, which refused to allow the United States to use British bases and Cyprus to airlift resupplies to Israel along with the rest of the members of the European Community.
Canada shifted towards a more pro-Arab position after displeasure was expressed towards Canada's mostly neutral position. "On the other hand, after the embargo the Canadian government moved quickly indeed toward the Arab position, despite its low dependence on Middle Eastern oil".
Although lacking historical connections to the Middle East, Japan was the country most dependent on Arab oil. 71% of its imported oil came from the Middle East in 1970. On November 7, 1973, the Saudi and Kuwaiti governments declared Japan a "nonfriendly" country to encourage it to change its noninvolvement policy. It received a 5% production cut in December, causing a panic. On November 22, Japan issued a statement "asserting that Israel should withdraw from all of the 1967 territories, advocating Palestinian self-determination, and threatening to reconsider its policy toward Israel if Israel refused to accept these preconditions". By December 25, Japan was considered an Arab-friendly state.
The oil embargo was announced roughly one month after a right-wing military coup in Chile led by General Augusto Pinochet toppled socialist president Salvador Allende on September 11, 1973. The response of the Nixon administration was to propose doubling arms sales. As a consequence, an opposing Latin American bloc was organized and financed in part by Venezuelan oil revenues, which quadrupled between 1970 and 1975.
A year after the start of the embargo, the UN's nonaligned bloc passed a resolution demanding the creation of a "New International Economic Order" under which nations within the global South would receive a greater share of benefits derived from the exploitation of southern resources and greater control over their self-development.
Prior to the embargo, the geo-political competition between the Soviet Union and the United States, in combination with low oil prices that hindered the necessity and feasibility of alternative energy sources, presented the Arab States with financial security, moderate economic growth, and disproportionate international bargaining power.
The oil shock disrupted the status quo relationships between Arab countries and the US and USSR. At the time, Egypt, Syria and Iraq were allied with the USSR, while Saudi Arabia, Turkey and Iran (plus Israel) aligned with the US. Vacillations in alignment often resulted in greater support from the respective superpowers.
When Anwar Sadat became president of Egypt in 1970, he dismissed Soviet specialists in Egypt and reoriented towards the US. Concerns over economic domination from increased Soviet oil production turned into fears of military aggression after the 1979 Soviet invasion of Afghanistan, turning the Persian Gulf states towards the US for security guarantees against Soviet military action.
The USSR's invasion of Afghanistan was only one sign of insecurity in the region, also marked by increased American weapons sales, technology, and outright military presence. Saudi Arabia and Iran became increasingly dependent on American security assurances to manage both external and internal threats, including increased military competition between them over increased oil revenues. Both states were competing for preeminence in the Persian Gulf and using increased revenues to fund expanded militaries. By 1979, Saudi arms purchases from the US exceeded five times Israel's.
In the wake of the 1979 Iranian Revolution the Saudis were forced to deal with the prospect of internal destabilization via the radicalism of Islamism, a reality which would quickly be revealed in the Grand Mosque seizure in Mecca by Wahhabi extremists during November 1979, and a Shiite Muslim revolt in the oil rich Al-Hasa region of Saudi Arabia in December of the same year, which was known as the 1979 Qatif Uprising. Saudi Arabia is a near absolute monarchy, an Arabic speaking country, and has a Sunni Muslim majority, while Persian speaking Iran since 1979 is an Islamist theocracy with a Shiite Muslim majority, which explains the current hostility between Saudi Arabia and Iran.
The oil crisis sent a signal to the auto industry globally, which changed many aspects of production and usage for decades to come.
After World War II, most West European countries taxed motor fuel to limit imports, and as a result most cars made in Europe were smaller and more economical than their American counterparts. By the late 1960s increasing incomes supported rising car sizes.
The oil crisis pushed West European car buyers away from larger, less economical cars. The most notable result of this transition was the rise in popularity of compact hatchbacks. The only notable small hatchbacks built in Western Europe before the oil crisis were the Peugeot 104, Renault 5 and Fiat 127. By the end of the decade, the market had expanded with the introduction of the Ford Fiesta, Opel Kadett (sold as the Vauxhall Astra in Great Britain), Chrysler Sunbeam and Citroën Visa.
Buyers looking for larger cars were increasingly drawn to medium-sized hatchbacks. Virtually unknown in Europe in 1973, by the end of the decade they were gradually replacing saloons as the mainstay of this sector. Between 1973 and 1980, medium-sized hatchbacks were launched across Europe: the Chrysler/Simca Horizon, Fiat Ritmo (Strada in the UK), Ford Escort MK3, Renault 14, Volvo 340 / 360, Opel Kadett, and Volkswagen Golf.
These cars were considerably more economical than the traditional saloons they were replacing, and attracted buyers who traditionally bought larger vehicles. Some 15 years after the oil crisis, hatchbacks dominated most European small and medium car markets, and had gained a substantial share of the large family car market.
Before the energy crisis, large, heavy, and powerful cars were popular. By 1971, the standard engine in a Chevrolet Caprice was a 400-cubic inch (6.5 liter) V8. The wheelbase of this car was 121.5 inches (3,090 mm), and Motor Trend's 1972 road test of the similar Chevrolet Impala achieved no more than 15 highway miles per gallon. In the fifteen years prior to the 1973 oil crisis, gasoline prices in the U.S. had lagged well behind inflation.
The crisis reduced the demand for large cars. Japanese imports, primarily the Toyota Corona, the Toyota Corolla, the Datsun B210, the Datsun 510, the Honda Civic, the Mitsubishi Galant (a captive import from Chrysler sold as the Dodge Colt), the Subaru DL, and later the Honda Accord all had four cylinder engines that were more fuel efficient than the typical American V8 and six cylinder engines. Japanese imports became mass-market leaders with unibody construction and front-wheel drive, which became de facto standards.
From Europe, the Volkswagen Beetle, the Volkswagen Fastback, the Renault 8, the Renault LeCar, and the Fiat Brava were successful. Detroit responded with the Ford Pinto, the Ford Maverick, the Chevrolet Vega, the Chevrolet Nova, the Plymouth Valiant and the Plymouth Volaré. American Motors sold its homegrown Gremlin, Hornet and Pacer models.
Some buyers lamented the small size of the first Japanese compacts, and both Toyota and Nissan (then known as Datsun) introduced larger cars such as the Toyota Corona Mark II, the Toyota Cressida, the Mazda 616 and Datsun 810, which added passenger space and amenities such as air conditioning, power steering, AM-FM radios, and even power windows and central locking without increasing the price of the vehicle. A decade after the 1973 oil crisis, Honda, Toyota and Nissan, affected by the 1981 voluntary export restraints, opened US assembly plants and established their luxury divisions (Acura, Lexus and Infiniti, respectively) to distinguish themselves from their mass-market brands.
Compact trucks were introduced, such as the Toyota Hilux and the Datsun Truck, followed by the Mazda Truck (sold as the Ford Courier), and the Isuzu-built Chevrolet LUV. Mitsubishi rebranded its Forte as the Dodge D-50 a few years after the oil crisis. Mazda, Mitsubishi and Isuzu had joint partnerships with Ford, Chrysler, and GM, respectively. Later the American makers introduced their domestic replacements (Ford Ranger, Dodge Dakota and the Chevrolet S10/GMC S-15), ending their captive import policy.
An increase in imported cars into North America forced General Motors, Ford and Chrysler to introduce smaller and fuel-efficient models for domestic sales. The Dodge Omni / Plymouth Horizon from Chrysler, the Ford Fiesta and the Chevrolet Chevette all had four-cylinder engines and room for at least four passengers by the late 1970s. By 1985, the average American vehicle moved 17.4 miles per gallon, compared to 13.5 in 1970. The improvements stayed even though the price of a barrel of oil remained constant at $12 from 1974 to 1979. Sales of large sedans for most makes (except Chrysler products) recovered within two model years of the 1973 crisis. The Cadillac DeVille and Fleetwood, Buick Electra, Oldsmobile 98, Lincoln Continental, Mercury Marquis, and various other luxury oriented sedans became popular again in the mid-1970s. The only full-size models that did not recover were lower price models such as the Chevrolet Bel Air and Ford Galaxie 500. Slightly smaller models such as the Oldsmobile Cutlass, Chevrolet Monte Carlo, Ford Thunderbird and various others sold well.
Economical imports succeeded alongside heavy, expensive vehicles. In 1976 Toyota sold 346,920 cars (average weight around 2,100 lbs), while Cadillac sold 309,139 cars (average weight around 5,000 lbs).
Federal safety standards, such as NHTSA Federal Motor Vehicle Safety Standard 215 (pertaining to safety bumpers), and compacts like the 1974 Mustang I were a prelude to the DOT "downsize" revision of vehicle categories. By 1977, GM's full-sized cars reflected the crisis. By 1979, virtually all "full-size" American cars had shrunk, featuring smaller engines and smaller outside dimensions. Chrysler ended production of their full-sized luxury sedans at the end of the 1981 model year, moving instead to a full front-wheel drive lineup for 1982 (except for the M-body Dodge Diplomat/Plymouth Gran Fury and Chrysler New Yorker Fifth Avenue sedans).
Decline of OPEC
OPEC soon lost its preeminent position, and in 1981, its production was surpassed by that of other countries. Additionally, its own member nations were divided. Saudi Arabia, trying to recover market share, increased production, pushing prices down, shrinking or eliminating profits for high-cost producers. The world price, which had peaked during the 1979 energy crisis at nearly $40 per barrel, decreased during the 1980s to less than $10 per barrel. Adjusted for inflation, oil briefly fell back to pre-1973 levels. This "sale" price was a windfall for oil-importing nations, both developing and developed.
The embargo encouraged new venues for energy exploration including Alaska, the North Sea, the Caspian Sea, and the Caucasus. Exploration in the Caspian Basin and Siberia became profitable. Cooperation changed into a far more adversarial relationship as the USSR increased its production. By 1980 the Soviet Union had become the world's largest producer.
Part of the decline in prices and economic and geopolitical power of OPEC came from the move to alternative energy sources. OPEC had relied on price inelasticity to maintain high consumption, but had underestimated the extent to which conservation and other sources of supply would eventually reduce demand. Electricity generation from nuclear power and natural gas, home heating from natural gas, and ethanol-blended gasoline all reduced the demand for oil.
The drop in prices presented a serious problem for oil-exporting countries in northern Europe and the Persian Gulf. Heavily populated, impoverished countries, whose economies were largely dependent on oil—including Mexico, Nigeria, Algeria, and Libya—did not prepare for a market reversal that left them in sometimes desperate situations.
When reduced demand and increased production glutted the world market in the mid-1980s, oil prices plummeted and the cartel lost its unity. Mexico (a non-member), Nigeria, and Venezuela, whose economies had expanded in the 1970s, faced near-bankruptcy, and even Saudi Arabian economic power was significantly weakened. The divisions within OPEC made concerted action more difficult. As of 2015[update], OPEC had never approached its earlier dominance.
